    When I want to watch a DVD connected to the HDMI system, the display(video) comes on every 5 to 10 seconds and otherwise I get the snow screen and flickering.

    I have tried changing the HDMI cables but they are fine. It appears the Receiver is the problem. Given the unit is in a cabinet and gets very hot could it mean the circuitry is cooked???

    appreciate your help

    My issue is the same as tony67... the display on the reciever itself stopped working. Any ideas would be appreciated.

    no display on Onkyo 875 receiver

  • Anonymous Jun 02, 2008

    Onkyo TXDS797 Front Panel Display Blank or Gibberish. I've tried resetting the receiver (Video 1 Button on Receiver held while pressing Standby Button) but each time it comes back on for about 12 seconds and then goes blank again. Already had to send it back during Warranty for the surround channel "popping " error fix. Sometimes the display will come back but only displaying random lines looking like Martian characters. Most of the time it's blank now. It will allways display menu settings on the TV Screen when the TV is hooked up as monitor but not on the Receiver itself. I suspect either an overheated/faulty chip, or an oxidized connection, or a bad solder joint.

    If it's a chip, does anyone have any suggestions as to which it might be (possibly Q7502, the M66005-0001FP on the Display Circuit PC Board, or Q7501, the 16-BT-96GNK, the FL Tube itself - hopefully not Q7201, the Submicroprocessor itself, the M30624MGA-359FP)?

    Looks like this display business is not so rare with TX-SR875. Mine also went out for no reason. I would really appreciate if some of you guys with blank display succeed to solve the problem, to post here what have you done. And by the way - for those who's display is still off - the setup is still possible through on-screen display (connect the receiver to a screen with HDMI) - at least in my case everything works just perfect, except the display itself.

    Dead display, looking for schematics/service manual to repair - e-bay purchase, no warranty.
    All voltages wfs seem correct, filament voltage present, etc

    Overall insanely hot, I installed HS over the Reon chip and added two low noise fans externally (powered via the switched AC plug)

    i have the same problem my display just switched of,so im taking it back its still under garentee thank god

    No display on the front of the unit.  $1,400 for this POS.  :-(  Onkyo said to bring it in for service.  They should recall it and pick it up.

The 10 Ohms resistor R9304 in series with the the 44V display power supply was open.

How to find it:
Remove the to cover.
On the right hand side of the front panel you will see on the side a wide white flat cable going toward the back of the receiver.
Beside it is a 4 black wire band connecting the front panel to a 3x4cm power PCB which is parallel with the front panel inside the receiver (attached to the front frame).
It has visible on the left side a diode bridge and a fuse - above the fuse you can find the R9304, a SFR16 package (1x3.5mm) marked BrownBlackBlack.
Check continuity.Replace if open wit a 1W resistor
Good job ONKYO, save 1/3 of a penny...

For the DIY:
As an added step I replaced the R9304 with a 2W 47R resistor, replaced the series transistor regulator Q9301 (tall TO92) with a bigger package (isolated TO220) and one of the two series 22V zenners from the base - D9310 - with a 10V one.
Output voltage drops from 44V to 34V, display is slightly dimmer but overall stress is down.

Good luck!

    This solution worked for me! I replaced both R9304 and R9310 with 10 Ohm 1W resistors and the display is working like a champ! Kudos to you, friend!

Replacing the resistors marked, 9304 & 9310, on the display board, fixed the problem.

My configuration:
ZONE 1 (living room)
DishNetwork Dual Tuner DVR Tuner 1 [S-Video out] -> [S-Video in] ONKYO TX-SR875 [HDMI out] -> [HDMI in] Sony KDS-60A3000 rear projection TV

ZONE 2 (living room)
DishNetwork Dual Tuner DVR Tuner 2 [Composite Video out] -> [Composite Video in] ONKYO TX-SR875 [Composite Video out] -> [Composite Video in] Samsung AQUOS LCD TV

Problem:
ONKYO receiver stops sending video signal to my ZONE 1 Sony TV through the HDMI connection. ZONE 2 may still receive video. (NOTE: the issue might be related to the upconverter circuitry?)

Symptom:
I couldn't see any video, but I could hear the Tuner 1 audio through my ONKYO. An important clue is that I couldn't see ONKYO's on-screen display menu on my TV when hitting the [Setup] button on my remote. But, I could see my TV's Sony-based menus and display options.

Solution:
1. Put all ZONES in Standby mode using the remote. Hit these buttons on remote: [Receiver], then [Standby]. [Receiver], [ZONE2], then [Standby], [Receiver], [ZONE3], then [Standby]. You should NOT see any lights on the ONKYO except maybe one red led near the power button.
2. Pull the power plug out of the back of the ONKYO, and leave unplugged for 20-30 seconds. Turning off any power center it is connected to isn't enough. You MUST unplug the power from the back of the ONKYO for 20-30 seconds.
3. Reconnect the power cord to the ONKYO.
4. Using the remote, set ZONE1 to a video source known to be working. If you don't see video, try leaving the power cord off for a longer period.

I know it sounds too simple to work, but that's what brought the video back for me the few times the video stopped displaying. Hope it works for you.

R9304 or R9310 are broken, if no light in display. This are 10 ohm resistor sitting on the board behind the volum knob in front.

Display has become almost illegible


Maybe your Contrast is screwed up. Try soft resetting, then hold "Alt" and the ">" or "<" key at the same time. You can also see if you can turn up the brightness, using the two keys next to the delete key.
