ICOM IC7610 : Pannes rencontrées

Looking at an audio analysis program fed by the rig's USB, I was surprised to see a heavy peak at 60 Hz. Since we have 50 Hz supplies and the rig is fed by DC it cannot be supply related.
It did not go away when unplugging the microphone so I now wonder if the rig electronics generates that into the audio system.

The acoustic noise generated by the fan when it comes on is also of concern that may need sorting out.
My headset mic picks it up and is quite audible in the earphones and hence transmission.

../..

Using the supplied HM219 (not directional) or my Heil proset plus.
Distance 1m or further. This 250Hz vibration seems to carry far.

../..

Generally one is not a meter away but I pick it up even there and further.
A friend has complained of the same thing. We like a quiet shack hi.
The trouble is the pitch of the noise. It is not low frequency enough.
My settings are: Mic 30%, Monitor 50%, Comp 4, TBW WIDE or MED.
That is enough to drive my 500W linear with 25W.
I have not opened the cover but suspect the fan is rigidly mounted to the frame or maybe has ball bearings.

I would like to ask a small favour of all who have experienced main receiver audio loss on their IC-7610.
Please e-mail me (off-list) a short description of the operating conditions and station configuration at the time of the failure, and mention what you did to restore normal operation. I shall forward this information to my Icom contacts for further analysis.

I had a few issues with my new 7610. HRO has a return policy of 10 days.
After the tone issue and no volume control. Also I think HRD with the settings might cause some issues.
I took it back to store. Bought a 7300.
I'll wait till after Dayton in the hopes they get these radio issues taken care of.
Maybe after Dayton they will also have some discounts and rebates. Hi
I know it's not all the radios having the problems, but it's not worth $4000 dollars
and all the aggravation the way it is to me..

It happens so infrequently, 3 times in 2 months, and recovery so painless why all the fretting over a minor bug that will be fixed shortly?
Tim W4YN

Symptom appears if I qsy to another band or simply after I have transmited
1. Rf on main and sub set to 12 o'clock
2. Firmware 1.04
3. Nothing but power and coax connected
4. Tried multiple resets (full) no joy
5. Turned off rig for 15 minutes
6.Turned back on all seems fine
7. Receive goes dead just listening to a QSO. repeated step 4, 5,and 6

Well, it finally happen to me after almost a month of owning the IC-7610, I experienced a No RX failure.  Specifically, the RX went dead with no signals being heard or displayed on the spectrum scope.
It happened on 75 meters, LSB, whilst turning the VFO to my scheduled frequency.

Important observation:  As soon as I crossed 3.768.000 moving in the direction of 3.800.000, I heard a relay click, and then the RX went dead!  I would have not noticed the relay click if it were not for the fact that I had the audio turned down.

I continued to move the VFO to 3.800.000 and stopped.  The RX was still dead!

Important observation: I reversed the direction of the VFO towards 3.700.000 and as soon as I crossed back over 3.768.000 my RX came back to life immediately after hearing the relay click again.

I don't think a relay click and No RX or a relay click and RX Working again is a coincidence.  I think the relay click has a causal connection to the No Rx.

As bad as that sounds, this type of hardware problem will be easy to trace to a specific lot of relays.  I would recommend that ICOM pull a sample of 3 percent from each lot of these relays and have an independent lab perform Destructive Physical Analysis (DPA) on them.  That will become an important step to rule out Infant Mortality (relays experienced an early life failure).  Does anybody know the reliability (MCBF) on these relays?  I am just curious.

I went to HRO and took the 7610 back and picked up a new one. As soon as i got it home i put in the Latest firmware.
Low and behold i have the same issues with the Decode as i did with the last two. I have pictures of what the decode scope looks like but
and not familiar on how to upload them to this group. I think with the pictures it would explain better.
As for what i had connected to the 7610 at the time of the issues with the receiver was the USB cable, DVI to HDMI to TV for a monitor.
Plus one speaker jack and that's all that was connected. I talked to tech at Icom but he's not in today so could not give him the run down
of the same issues on the new radio. Serial Number on the last radio is 12002376, this one i picked up today is 12001873 older than the last one.
If you need the pictures tell me were to upload them..
This is my third 7610.  All three had issues.

Just purchased 3 days ago. Came with 1.04 firmware so updated to 1.06. It has been working normally up until a couple hours ago.
I noticed the audio scope FFT was not displaying the received signal that was still shown on the scope side. No response to pressing
menu button. I then tried to power it off and it froze at the powering down message on screen. I had to shut the power
supply off to reset. It powered up by itself when the supply was turned on, so it did not remember that I pressed the power button.
Unit is back to normal and I've made a few contacts. Serial number range is 120022XX.
I have the RC-28 plugged in, as well as ethernet cable and rear USB2 cable, along with USB interface plugged into ACC1. All this was working and is once again.
I was toggling between TX and RX looking at the waveform from the USB interface (running FT8) mode was USB-D1. On 7.074 Mhz

Richard WB6NGC - Mai 2018

My receiver has started losing audio output on the main channel only.  When it goes silent I can move the volume control or touch the screen and it comes back for a while, but not permanently.  Have any of you had this problem, and if so did you find a solution.  I have the 1.06 software upgrade installed.  Robert, W7GKM - Mai 2018 

Have you by chance heard what ICOM plans on doing about all these Screen Washout problems?  Given that my IC-7610 serial number falls between the S/Ns of the screen failure events reported so far, it's most likely my display is defective too along with many others.

It has been suggested that maybe I should leave my radio on 24/7 to accelerate the opportunity to fail before the warranty runs out.  This is silly and I'd rather see ICOM step up and identify all the affected radios by S/N so we can schedule our returns for new displays.

Based on reading though this group's messages, it appears that this is a known problem and based on the S/N data provided so far by this group, there are a lot of potential radio's that will most likely experience a screen failure over the next many months.  

I would like to point out that the number of incident reports is Not the main issue.  It's the number of radios involved by S/N in the population from the lowest S/N to the highest S/N where a radio has experienced a screen failure.  Please see the screen failures reported below:

1) K3HTK,  2/1/2018, No S/N, Top left side washed out
2) N8DC, 2/1/2018, 12001026, Lower left side washed out
3) K6DHL 2/3/2018 12001103 See Spec Scope burn in
4) WB5JJJ,  5/13/2018, 12001105, 1/4 of the screen is fading
5) W5JMW, 5/11/2018,  No S/N,   Burn in of previous screen
6) N8DC, 5/29/2018, 12002146, Display issue again and this time the right side of the screen is washing out
7) N0JX, 6/1/2018,  No S/N, Right side Washed out
8 ) N8AWW, 6/2/2018, No S/N, Similar problem (washed out)

Interesting history that was reported to this group by W5JMW ON May 11:

No Barry, It is only some units. Icom told me the vendor assured Icom this could not happen. When Icom saw this I understand they quit using that model.  I spoke to Icom last week.  Since there is a full year warranty they suggested to hold and see if any other problems occurred.  I would do the same thing again, even after the screen issue.  You can easily see the screen.  There is a burn in of a previous screen way in the background.  I would suggest either a brand new one or a re-pack that has full warranty.  Whatever problems they will repair..73 john

Adam, please work your magic and see what can be done to ensure the best possible outcome.

The hum is heard when using a touch stylus, but not as loud.  My experimenting to identify the conditions which produce the loudest hum, I noticed the following:  Please note: Only happens on 6 meters.

    1. As I use palm of my hand and slowly approach the screen, the hum gets louder and louder.  I don't have to touch the screen for the hum to be heard.
    2.  Disconnected antenna and no change.
    3. Turned off all devices in shack, no change/
    4. Measured for common mode between equipment (AC/DC) and get zero.
    5. Toggling P.AMP from off to 1 & 2 increase the volume of the hum.
    6.  Hum is not heard when I stay away from the screen with any objects.

Power supply has a grounded plug.
   
Hope this helps!

Hi,

got the 7610 last week. Saturday morning the RX was dead after switching on. No chance to get them back, even with a full reset.
Not a big issue as the dealer wants to replace them, but anyone has experienced the same?

09/10/2018 a écrit:Just today, a bright, persistent, perfectly vertical green line suddenly showed up on the display of my IC-7610 (firmware v1.11).  I've tried power cycling the unit but the green line is still there.  On my display, this green line appears alittle over an inch away from the left side of the touch screen (it's positioned directly above the "M.Scope" physical button.

Anybody else having this problem with their IC-7610 display?

my External display monitor, which is Vibrant, Contrast, and  Colours  are nice,
But on the ic7610 screen, complete lack of contrast, even with backlight  at 100%,
The black background looks more grey then black, I also see image persistence,
on the screen, more so when i go into menu and set, If i set the lcd backlight to 50%
it just looks dull , I have no other screen problems just the above , but to my eyes
it just does not look correct, Anyone out there see similar with their rig, or do i need
new glasses hi. Serial no is 13001376  rig is 10 mth old.

14/11/2018 a écrit:I took delivery of my 7610 in mid December and I had my screen replaced in June.  However the replacement screen is starting to show the same symptoms as the original screen with bleed through.  The problem is very evident when I first turn the radio on but after 30-40 minutes it's almost unnoticeable.   Im concerned the condition will continue to degrade over time.  I dread having to ship the radio off to Michigan again.

15/11/2018 a écrit:Good morning.
FYI, I had my IC7610 screen replaced in late July. 
I just returned my IC7610 to have that (replacement) screen replaced. It looked worse than the original screen that was replaced in July.
I purchased my rig in mid January.

15/11/2018 a écrit:My first 7610 had two replacement screens go bad. A new rig sent as a replacement is beginning to show symptoms already. I will hold off on this one to wait for Icom to
straighten it out before sending it in under warranty... This MUST be addressed...

21/06/2019 a écrit:My second display is also degrading. I was offered a replacement that the local ICOM repair shop had in stock 
but told them they better scrap it since nobody in their right mind would accept it. I will turn my unit in for repair 
once I am sure to get the new display panel. 

Neither the local dealer nor the repair shop have any information on the display case.  
ICOM does not seem to communicate at all on this. Not a great strategy for building 
customer confidence. Or dealer confidence, for that matter.

11/05/2018 a écrit:Has anyone else had their radio reboot during cw transmission? It's happened to me twice recently now. And once again this morning while I was running VARA an AFSK mode. RF getting in somewhere maybe? Funny thing is, everything was working just fine for a month or so and then it just started happening. Haven't made any big changes to my station or anything. Puzzling and therefore troubling.

Many thanks..  Ridge/N3JUY

15/03/2018 a écrit:I have had this problem since I got the radio.The vfo frequency drops to a memory channel for no reason.When this happens there is no audio,screen goes dead,no audio.I found that if I hit the quick menu I could restore it fairly easily by just hitting vfo button.Today I found the fix.I am running a icom-7610 and a om power 2000a+.I found that the amp was polling the radio for frequency.The radio took one of the polls as a command to switch to memory.The final fix for me and perhaps others who are having similar experiances.Go to menu,set,connectors,civ...and change from auto baud to a fixed baud rate.I chose 4800.The reason for the slow speed is because it's just frequency,Doesn't have to be fast.I don't know if this will fix problems with any amps that use civ.It die on the ompower.I want to thank all on this list.I want to especially thank Ray Novak with Icom for all the support He gave me.At times this was driving me nuts.He listened to my complaints and help calm an old man,hi..hope this helps,73 john w5jmw

Aucune idée si la méthode ci-dessous améliore ou non l'affichage.
Je la conserve ici mais à tester à vos risques et périls...

I've been reading about "resetting the crystals" in LCD screens so I thought I would experiment on my IC-7610 to see if I could affect the screen. It seems to have helped mine and maybe 
some others could try this and report their results. 

What you want is the brightest screen possible running overnight or at least for a few hours. 
To accomplish this:
1. Go to menu / Set / Display / Screen Saver --- Turn off
2. LCD Backlight 100%
3. Display Type B (ugly mode)
4. Meter type (Normal Screen) BAR
5. Push M.Scope until scope is off
6. Mine looked worse on the right side so I punched VFO B to light up the meter on that side.
7. Go to bed
8. Change everything back to normal.

Ideally a totally white screen or bright, random colors would be better for this but not available to my knowledge.

So that's it. Let us know what happens. Mine looks better. There's room for improvement of course.

My experience compels me to wait for the failure review results and/or history of success with the new displays as I have run and/or participated in thousands of complex system and component level failure reviews on multi-billion dollar programs during my 45 year working career. 

For those wondering why I have not sent my radio in for a screen replacement is simple.  The replacement screens have been reported to exhibit the same grayed out and burn-in (persistence) effects.  That known fact was a show stopper for me and convinced me that there was no point of getting a display screen replacement without knowing the root cause of failure.  Besides, I just did not think it would take this long to solve the problem.  Even today, I still do not know for certain if the problem is in the display screen or the radio and I don't think ICOM knows either. 

It's important to note that ICOM told me they will provide screen replacements even on the radios out of warranty at no charge.  

Everything else about the radio IMHO is World Class and it's just unfortunate that the display screen for the radio in my case is not and has made my experience awful.  For this reason, my patience with ICOM is running thin as we are approaching the second year mark.
