re: TX-SR607

Hi!

As described in the thread even my display went out of business i while ago. I was a bit confused, but still solved the problem. On my board, the resistor was named R9001 (maybe different specs in different countries?), the servicemanual named it as R9010 mounted in the same position.

I changed the R9001 to a new 2,2 ohm 0,5w resistor and the display lit up just as I was hoping for. Wow!

Thanx a million for all you brainiacs out there who have the knowhow and interest in solving these kind of problems!

TX-SR607 Display Problems

I know that there are some fixes concerning the display.

I got a broken Onkyo TX-SR607 from Ebay. As i bought it, i knew that the frontdisplay was not working. So that was ok for me. I found a fix, and so that should solve my problemes, I thought.

BUt after checking the resistors placed on a board connected to transformer I was disapointed.
the AC voltage was ok, and there was a voltage drop on the resistor, so there should be around 100mA for the heater of the display. Hm 4V directly on the panel. So this was not my error.
And I couldn't find open solderings.

So these were the fixes I found.

Than I found the service manual here on hifiengine.
today i googled a little how this kind of display work.
I remembered that a voltage called VP or VP- (sometimes with sometimes without - in the manual)
was about 3.4V on my board.
Hm one of the voltages on the board should be negative I thought......

So I found a discreet voltage regulator
on the analog videoboard BAVD-0038/U0032 under the HDMI board.

AND I found a broken resistor called R9010 which should be 2.2 ohm 1/2watt
it was about 2Mohm. So I resoldered 2 4.7Ohm in parallel to have something around 2.2 ohm and the one i had where 1/4Watt, so everything was fine.

And I am back in the game, Display is nice and bright,

But I think his receiver gets really warm inside, I will use a fan inside.
I hope that the receiver will work a little longer.
The capacitor inside especially the smd soldered on the HDMI board don't like heat.

I hope some could fix his onkyo to. And I hope to hear of that

re: TX-SR607 Display Problems

Registered just to say thank you for this post.
With limited electronic knowledge I managed to fix the LCD display on my father-in-law's Onkyo TX-SR607 by replacing the 2.2 ohm 0.5 watt resistor R9010.
All in, a two hour job. It took longer to go down to Maplin and get the right resistor!

Once again, many thanks. Without this post the amp would have been binned.

Cheers.

Hello.
Would it be possible to add some photo's of the repair.
Thank you Olan.

re: TX-SR607 Display Problems

Hi,

My TX-SR607 had an issue where the On Screen Display (OSD) stopped working and then a few months later the front display also stopped working. I found this post while doing some research to see if any others have encountered the same types of problems.

I want to thank you because I have now fixed both problems based on the information here as well as information from other forums regarding Cap replacement on the HDMI board.

To fix the front display problem, I tested R9010, which is on the board under the HDMI board. In my case this resistor tested bad (over 10 Mohm). I ordered a pack of 2.2 ohm 1/2 watt resistors from digikey and replaced the resistor (Part #2.2H-ND - RES 2.2 OHM 1/2W 5% AXIAL). Voila, the front display lit up (Horray!!!).

While I was in there, I replaced 10 caps from the HDMI board (also ordered from digikey) and doing so fixed the problem with the On Screen Display (Horray!!!).
Part #565-3047-ND - CAP ALUM 100UF 10V 20% RADIAL
Part #493-1522-ND - CAP ALUM 470UF 16V 20% RADIAL

My unit is back up and running and again I thank you for the valuable information provided here!!

re: TX-SR607 Display Problems

I am wondering if anyone has been able to fix the front panel display problem that has happened to the sr-607 reciver i have read the detailed http://www.avsforum.com/t/857502/the-onkyo-tx-sr805-thread/17310 but as the layout of the 607 is diferant than the detailed pics on the 805 i am at a loss as to where i can find the the 2 resistors that need to be replaced
After reading the above thread i am wondering if i was to replace R9010 with a 10-ohm 1W resistor
will this solve my front panel display problem

Please i need to be able to fix this asap

Onkyo TX-SR607

The following was posted by HUNT on avforums and after following the instructions I managed to find the fult(the resistor was failing).

The display module of this model uses an FL (florescent) glass tube. For the display to work, the FL module (Q7002) must be supplied with low ACV to powerthe heater/filaments. Almost always, a no display condition would indicate low or missing ACV supply.

Proposed diagnosis / repair approach:

check continuity of R950 (8.2Ω / ½W) and replace if open;
presence of ACV between terminals P950 & P951 of the main transformer;
presence of ACV on pins 1-2 and 58-59 of Q7002;
in most instances, it would be a cold-solder condition. Fix is to re-solder.

R950 and the terminals P950 & P951 are on the small PCB board marked U0012 soldered to the main transformer;
Q7002 would be on the front panel display PCB marked as U003.

The value of R950 a reason:

8.2Ω - to limit the voltage current to the filament/heaters. Anything lower and the display goes brighter but heats up faster; higher and the display is dimmer but not as hot;
½W - serves as a sort of thermal fuse; anything higher and it will not burn up quickly enough; lower and it would constantly go open.

Thank you all very much for

Thank you all very much for donating information , very much appreciated , really useful.

Sadly: it is great while it works, but it is not reliable.

This amp, as several other Onkyo AV receivers seem to suffer from common problems, as is apparent when searching the web:
1. The front panel display fails quite soon.
2. The HDMI board fails, manifested by long connection times or inability to switch inputs.

There are several threads on fixing the HDMI board - it seems some capacitors overheat and pack up, but sadly I have found no threads with a fix for the first problem. And guess what, my display has packed up after 2 years.

So I will steer clear of Onkyo products as it is not just this model that suffers from these problems; several models have the same problems.

Thanks for the service manual, I might be able to find the fault.

HDMI board

I have the same issue with the HDMI board. Would get it repaired but not worth it

re: HDMI board

i have replaced all caps but still have a blue screen when setup i get the osd no problems my setup im familiar with had the unit 5 years.

smd caps replaced 16v 100uf x5 and 6.3vf 220uf x5 black negative to the flat side of the square. dnt know where to go from here pls help
