Onkyo TX-SR606 HDMI Switching headache

Plow Boy

Hi to all, I have a Onkyo TX-SR806 that is around four years old. For the past few months it has started not being able to switch from one hdmi to another. The sound coming will crackle and pop; it will take an extremely long time to for audio and video to come up. I've tried using all the hdmi ports with no success, is this the same problem occuring with the 606's? I would like to know what capacitors need to be replaced on my hdmi board since it is a little different than the 606 model. Thanks for your help.

My 606 is having issues, and is at the point of no longer tolerable. Before I buy some capacitors and track down a soldering gun, I want to make sure my problem is related to the caps.

I don't seem to have any problems switching HDMI sources, and it takes about 2-3 seconds at most. These are my problems:

- No OSD most of the time, just a blue screen.
- Sound and video will cut out, sometimes just sound, or just video. Sometimes for a split seconds, sometimes for a few seconds.
- Composite input will only display a blue or snowy screen with sound. I have to power cycle a few times to get picture.
- The newest issue, I'm starting to get horizontal lines around the bottom half of my picture.

I just want some input to see if my issue is related to the caps, or my unit is worse off than that.

I was ready to swap my old receiver in place of the 606, but first I wanted to rule out the HDMI cable. At first I thought that was it, and it was working great. 20 minutes later issues returned. Definitely seem to be the receiver is to warm. Took the cover off to let the heat escape more, seems to be working better now. Still have the issue with composite having no video until a power cycle.

For the TX-SR607 owners out there, I also had no analog video connections and no OSD. This was after I accidentally left my stereo cabinet door closed for several days in a row. I usually always left it open for some heat dissipation. Worked for a year and a half that way.

I successfully repaired mine by replacing all five 100uf 4V 85 degree caps with 100uf 10V 105 degree caps (digikey part# 565-3047-ND)

and all five 470uf 16V 85 degree caps with 470uf 16V 105 degree caps (digikey part# 493-1522-ND)

The 1uf 50VDC red thin film caps (digikey part# P4675-ND) were on backorder, but replacing the 10 caps above solved my problems. Since those 10 fixed it, I'm choosing not to add the 1uf 50VDC red thin film caps to the regulators unless my unit fails again.

I've no clue if replacing the five 470uf 16V 85 degree caps were necessary, but since my refurbished unit had obvious solder signs that those five caps had been replaced previously, I went ahead and replaced them with 105 degree caps to be on the safe side.

Since the obvious problem for the old caps was heat, I went ahead & ordered a controlled-speed dual fan setup off of ebay to sit on top of the receiver:

Search ebay for "Receiver/Amplifier dual-cooling fans/air-chamber bases" Or search the ebay seller "drmckenzie" If he doesn't already have what you're looking for, he can custom-make any fan setup you want.

I have the same board configuration as you. I think it's glue on that capacitor as mine only has it on the side (between it and the board), not on the top of the capacitor as yours does.

Did you do the capacitor replacement discussed in this thread and on the You Tube video? Was it successful? I'm just starting this project right now, so was wondering if you had done it. I'm still trying to get the cables connected to the board off without breaking anything, as there are unfortunately very few comments about that on the forum (and none in the video).

Hi guys, I have a TX-SR805 and I'm having pretty much the identical issue mentioned throughout this thread. When I have my HTPC hooked up during boot the image is all green and snowy, after it's booted it just displays all snow screen can't see any of the OSD from the HTPC. I can run the HTPC at 1080i60 and 1080p24, as well as other devices but if I up it to 1080p60 I get snowy screen.

I'm curious if the 606 fix will work on the 805? Are the parts different? Obviously this is way out of warranty so I'd prefer to just fix it my self. Any help is greatly appreciated.

I was having issues similar to those reported in this thread with my Onkyo TX-SR607; intermittent OSD and analog upscaling/conversion from composite and component sources.

I took a quick trip to Sayal and picked up five 100uf 35v caps, rated to 85C, electrolytic. The replacement of five 100uf 4v SMT capacitors on the bottom of the HDMI PCB did the trick. They're slightly bigger and bulkier than the originals (ok a lot) but they work. I now have OSD and analog upconversion/upscaling from both composite and component sources (cable tv and wii, respectively). My HDMI connections seem in good order as well.

Since the 607 board varies from the 606 (all 100uf caps are on a single side) I thought I'd share some images to illustrate their location.

Edit: Turns out I can't actually link to the images without posting five times :/


The trickiest part was disconnecting the black ribbon cable that attached to the board via two white connectors, which were impossible to separate. Instead I simply pulled the cable out of the mating connectors (exposing the leads) and slid them back in upon reconnection. I thought I might have hosed it but the connection was fairly solid on reconstruction.

In any case things seem good and if it ever goes again I know the fix is fairly easy. All said and done preparing the caps and soldering took less than five minutes, but the prep work and inspection to make sure I didn't fuck anything up took a good half hour to an hour.

Edit 2: Pics time!

Hi there,
I'm from Germany and have searched for information about the HDMI-Issue @ my Onkyo TX-SR606...
As there are different ways to solve this problem I looked also @eBay for professional help/information...but the one @ eBay/de was not very kind and would not be helpful to me, as he heared that I will do it on my own.
But I've found "davehtuc" @ eBay/com he's a great man and will help professional if you won't be able to solder this f**cking issue away by your own...

But also thx to everyone here in this forum you all were helpful and inspiring for me

I just purchased an Onkyo 606 and it looks like it may have issues as discussed in the pages I've read on this thread, but wanted to make sure.

1. I reset the receiver to its factory settings.
2. I have an hdmi cable running from my project to the HDMI out on the receiver
3. I have an hdmi cable running from my blu ray to my receiver

The OSD menu will not display and I don't get any type of sound from the speakers/signal from the blu ray player.

Am I screwed, or am I missing a setting on the receiver?

Of Onkyo doesn't fix it and I have to fix it myself which capacitor would be best to get?

Hi All

Just my little bit of an update . My amp had the hdmi touch of doom. So I opted to go for the fix which seem to have worked a treat.. I now have vidoe 1080p and OSD this dispite the fact i get VD???????. The question i have is I cannt seem to find the caps show in the other posts. I have managed to find 1uF 50v Metallised Polyester (PET) Capacitors can i use these instead o or can I use 0.1uf 50v Metallised Ceramic Plate Capacitors. Or do they have to be the ones specified.

OK an update, the fix seems to work on the video side. but I get sound through the TV speakers, as I have pass through enabled. but no sound at all from the sround speakers.I have checked the joints and there seems to be no unwanted solder. I would add that I ended up using the 1uF 50v Metallised Polyester (PET) Capacitors in the end.

Any ideas, or has any one come across theis before.

I would like o sort this out before i attempt to repair the second 606 i have.

This thread seem to be the excellent thread about onkyo hdmi board repairs. I've bought a SR607 with the switching/OSD fault and will attempt to repair the unit as soon as I receive it.

As I understand some board revisions have voltage regulators made by ROHM, which don't need the addition of a filter cap. Wouldn't it be better to to replace the Toshiba caps with the ones from ROHM, as it seems they are less likely to oscillate.

Also does anyone have the (body) size of the original SMD caps for the SR607?

Just replace them with the 1uF 50V ones. I read somewhere that onkyo replaced the caps that are shipped to service centers to 1uF ones. They just didn't update the bulletin.

You say you get VD???????. Can you check if the upscaling/component works? As I understood the VD??????? means you have a corrupted video eeprom.

I am another victim of the 606 HDMI issues. I have followed and read through this thread carefully.
My receiver is 3 years old and has had this issue for at least 1.5 years. I have ignored it and bypassed the hdmi functions until now.
I finally decided to fix it and opened up the unit to inspect and remove the HDMI board for repair.
Before removing the board I noticed one of the 220uf caps tilted. When I touched it it just flopped over. Solder connections were gone. As I looked around and gently touched the other caps included the 100uf ones, they all popped off with the smallest of touch. Even the regulators when touched slightly came off the board.
It appears to me this board was subjected to a great deal of heat eventhough it does not show any discoloration.
My question at this point is...Have any of you other forum folks experienced or seen the same on your HDMI board? I don't even know if it is worth trying to fix at this point. so many loose items now.
I can't imagine this was due to defective soldering but maybe.
Interested in anyones feedback. I believe it overheated as this receiver does run very hot and was in a small cabinet.
this unit might be headed for the garbage can. What a bummer.

Can you post a picture? If the solder pads aren't damage go ahead and replace the caps and resolder the regulators. If the regulators are trashed you could try to replace them. I think the regulators are in a DPAK (TO-252) package.

When the caps go bad the ESR increases, causing the regulators to oscillate with in turn causes even more heat being generated. Also when the regulators are oscillating they begin to output dodgy power witch makes the HDMI chips to go mad.

When replacing the caps choose high quality ones with low ESR.
