How to DIY ; TX-SR576/TX-SR606/etc HDMI daughterboard repair (for dummies?) - Page 9

Everyone with this fix, have you check your VD firmware version numbers? I checked the Video Display (VD) firmware version and it displays all ???????? i assume at this point i am SOL on this fix. Any solutions for removing the EEPROM and getting it reprogrammed, or simply replaced. Any ideas where i can order a new board for my DTR 5.9

How where do you check firmware version? I'm seeing the typical symptoms here (on a 606) - I'd like to see if my EEPROM is cooked (yet).

While on, press and hold the display button then hit the off/standby button. You'll get a quick display before it goes out cycle with the tone > button or i think its tone + on mine, you will a few different firmware version numbers on the 3rd press you should get VD then numbers. If its ???????? you VD is corrupt and from what i can tell are SOL.

I just got mine back from Onkyo.

Original Issue:
No OSD, no upconversion, HDMI stopped working for some devices

After self repair:
HDMI switching was working great, but still no OSD and no up-conversion

After Onkyo repair:
Everything seems to work

it looks like they replaced the whole HDMI daughtercard because it looks very different from what I had before.

Mine was out of warranty and they granted me a repair exception. Give it a try before you do the repair yourself(unlike me) and just try to be nice, maybe you will get helped too. I am still surprised they fixed it even after I tried to fix it.

Hi

Thx for the DIY CZ_the_DAY.
I have Onkyo TX-SR576 and got the hdmi problem. My amp had to warm up few minutes at first until it got hdmi connection to work. after few months the time needed to warm up started to be about an hour.
I followed your guide and replaced six 100uF capacitors from hdmi board. New ones are 100uF/16V 105 C.
Now after few minutes test the hdmi seems to work like charm.

Thx again.

Problem with my TX-SR606 has progressively gotten worse, at this point I just leave the receiver on, as it can take almost 1/2 hour to "warm up". Only happens on the DVD HDMI input, the VCR/DVR input works just fine, although I think it tried the other HDMI inputs with my PS3 and could not get anything. No OSD with any of the HDMI's. I will have to do this fix sooner than later it seems.

Edit:UPDATE--Replaced C8072,C8096,C8602,C8609, and C8162, before would have the issues listed above.
AFTER: HDMI connects like it should, OSD is now working as well.

I used the Radio Shack 100uf 35V capacitors.

I Just repaired my 2.5yr old HT-R960 (ht-s9100 THX) by replacing :
10x 100uF caps
5x 1uF caps
and one 220uF cap

1080p and pass-through now works as it should, the osd still seems broken... but it only worked for about a month when i first bought it, so im used to look at the receiver when changing settings anyway.

I spent about 6 euros on parts.

thanks to all contributors here for all the info, you know who you are

In case you life in The Netherlands like i do, here's where i got the parts:

It isn't because of Google, even if it helped me to find this thread. No it is because of CZ_the_DAY and all the fantastic content providers like him. THANKS

I have today fixed my TX-SR606 by replacing the five suspect 100µF capacitors on the HDMI board. After this small surgery everything is back to normal, all my HDMI ports now works flawless (PC, Mac and PS3 1080p) and OSD is back.

I live in Sweden, Stockholm, and I used the following capacitors:
Elektrolytkondensator 100 µF 25 VDC, 25ZL100M63X11 from ELFA.

[quote=stufq;20051947]Hi
As I have mention somewhere above I have been very successfully with my repair.
I have attached some pictures after replacing caps and fitting the fan. I had to use fan Speed Reduction Cable to slow down my 120mm fan.




Hi,
Just looking at the pictures that stufq posted and I see a small problem. It looks like you used 10uf @ 100v for the replacements. If it still works good then I won't rock the boat, but if not you might want to swap those out to 100uf.

[quote=runuts;20148519]
Wow !
Is working no issue handshake with xbox is a bit slow (2-3sec) but except that no issue, osd work. But still can't believe what I have done... amazing...
Thanks for pointing that out but I can't be bother to take it apart again if is working.

First off, Thank You Very Much for the information on this problem.
It has been a long time since the receiver has worked this well. It was looking like the dump for my 606 if this didn't work out.

Original Issues:
1. OSD would work some times
2. Picture/audio would blackout in random half second intervals. Worst when cold and became more frequent as months passed.
3. Short white lines would twinkle across picture on all hdmi inputs. The input device i.e. Satellite @1080i, produced most problems. PS3 and Blu ray worked ok on all inputs (both @ 1080p)

Repair:
Replaced all ten 100uf/4v surface mount capacitors with radial 100uf/16v @105C capacitors. I figured if the 4 were bad, an extra 15min and $5 was time/money well spent.
If you are in Calgary, MRO Electronic Supply had a better selection and pricing on capacitors. They are just down the road from active electronics in the NE.

Conclusion:
Repair worked, all noted problems above have been fixed. I can't thank everybody enough in the help on this one.

isn't the dtr5.9 still under the 3 yr manf warranty ?

Hey folks -

First I just want to thank you all so much for providing such a valuable resource. I purchased a TX-SR606 about a month before CC went out of business. I guess 2-years ago? Year and a half? Of course no receipt because that was there big selling point - they keep receipts on file for you!

Anyways, my HDMI switching was acting up, taking a very long time until it would "warm up".

I bought a new TX-SR608, then a few weeks later found this so thought I'd take a whack at fixing my old one.

Long story short - I couldn't figure out how to get the damn power cable disconnected and ended up breaking it.

I did resolder all capacitors as described here.

Any advice now? I thought about disconnecting the cable from the other side, and simply hardwiring each wire to it's terminal (how do I determine which is which?), but where it connects to the otherboard seems more difficult to remove and I didn't want to risk breaking that side too!

I COULD try soldering each connection directly leaving the cable intact, but it would be very awkward to work like that, and further more I STILL have the trouble of determining which wire connects to which pin.

The board is etched "Power / Ground / Power / Groud" so I imagine it would be very bad to guess which goes where.

Any advice would be GREATLY appreciated. I feel like I'm so close to fixing this.

Thanks,
J

I apologize for the giant picture, I didn't mean it to be that big, all six pins are intact on the HDMI board, despite the picture looking like one is missing, sorry I couldn't get a better shot.. it's through a magnifying glass w/ my cell phone.

I may have answered my own question after doing a little homework.

What if I grab the following from radioshack?
it wouldn't let me link - but the item is a 6 position polarized connector (male and female).

Both male and female and connect the 6 wires to the plug, and solder jumper wires from each pin on the board, to the otherside of the plug?

This way I keep the ability to disconnect the HDMI board should I need to in the future?

I do recall the power cable did not twist, so I shoudl be able to go pin to pin from left to right.

Any special wire I need to use to go from the pins on the HDMI board to the plug?

Sorry for the questions, my electronics experience is limited to desoldering/soldering in a chip on an Xbox!

I had to join the forum just to say

THANK YOU!!!!!!!!!!!!!! CZ_THE_DAY

My TX-SR706 stopped recognizing 1080P sources a couple months ago. Unfrotunately it is also the XM receiver for my whole house music system on Zone 2, so replacing it with a new model was NOT an option. (only 2 versions offer sat anymore, and they use the Sirius tuner, not the XM version I have)

This is also the receiver for the 52" LCD over my fireplace in the formal living room, so although not much is watched in there as people want to see everything on the big screen, I did not want to lose 1080P viewing capability in that room.

I stumbled upon this after calling Onkyo, and they were worthless. (had the receiver for about 28 months - out of warranty)

The nearest Onkyo service center was an hour away, and they said they would need to replace a dozen capacitors, so........

That lead me to finding this site while searching for capacitors.

FYI - I did not diconnect any of the cables to the HDMI board, I simply removed the screws, and twisted the board around to work on it.

It required 12 capacitors to fix it.

Thank You SOOOOOOOOOOOOOOOOOO much for saving me a LOT of time & money.

Total cost for me was about an hour and $20 (including shipping) for 25 high heat capacitors from a place called mcmelectronics. (they have a coupon online for 15% off)

Hey Guys, I ordered these parts but just noticed that my 100uf capacitors are 4v on the board. Did I order the wrong parts for my receiver? I was planning on installing them tomorrow. Please let me know if I should go ahead. Thanks!

Well for what it's worth I had the 7 each 100uf capcitors changed out on my Onkyo 805 HDMI board and it did not fix the problem. I put the board back in, got sound but no video. I know the cables are good cause I checked them with another set up. Any suggestions? Really frustrated.

Just wanted to express my gratitude for this thread. I followed cz_the_day's instructions and was able to get my sr606 working like I remember. Funny how it took me less time reading the thread, buying the parts, and soldering them on than all the time I've spent trouble-shooting it the past year.

Also wanted to share my experience. My soldering & electronics skills are of the beginner level. I was nervous about trying this. I thought I would ruin the receiver. From Radio Shack, I bought 9 100 uf (part number 272-1028) capacitors and 1 220 uf (the local store only had 9 and I was eager to try this out). They were the 35WVDC variety (for those worried about not using the exact same as the originals). Maybe I should've only replaced the 4 capacitors that were mentioned in the service bulletin. I guess I didn't want to run through multiple passes to see if it worked and I also thought fresh caps all around would be better in the long run. How concerned should I be that one cap is 220 uf? From the little I know about electronics and caps specifically, I would think it's ok.

Since these are much larger in size than the originals, I just made short right angle bends in them to solder them on and left them sticking out. I removed the sirius daughter board underneath to not have to worry about them bumping anything since I don't use sirius.

I did get tripped up on those wires in that white connector thingie. I almost broke the white part off trying to get them out - it's not like a connector I'm used to. Luckily, I remembered cz_the_day's note about those. Just wanted to remind others that you need to push *in* on the end of the white piece to release the wires- it stays on the board and only the wires come out.

Having the case open and tons of extra computer fans around, I thought would be a good time to try and wire up a fan to help with air flow. Since not using the sirius board, I thought I could use the power wires from its wire harness to power the fan. I read on the board that pins 8 & 9 are the + & - 15V. I solder those to pins and pushed the two pins into case fan connector. Unfortunately, no luck getting the case fan to spin. If anyone has any recommendations on how to power the case fan, I'd be grateful.

Cheers and thanks again,
Erik

Success!!!

Went back and reread the thread and realize that my question was answered already. Changed out all the 100 uf capacitors, added the 1 uf bridges, and changed the 220 uf capacitor. Also added a fan. Whoo hoo! For the cost of $25 my receiver is working again!!!

Hey Guys,

Was wondering if any of you gurus who have repaired your Onkyo's might be able to suggest a fix for me on mine.

Unit now powers on, bad news, it only stays on for about 10-12 seconds.

The owners manual says that if the unit powers on then powers back off after a few seconds then the amp protection circuit has been activated. It says to try this:

Unplug the unit from the wall, disonnect all speakers and inputs. Wait 1 hour, turn the volume up to max the plug it back in. If this doesn't work then send unit to repair center. Well, as luck would have it, this did not work. I also tried a factory reset, that did not work as well.

Anyone have any other ideas? Anyone know how to deactivate the amp protection circuit? I think this would fix the problem, I really do.

PLEASE IF ANY OF YOU ELECTRONIC GENIUSES HAVE ANY IDEAS TO TRY PLEASE LET ME KNOW. I WOULD LOVE TO GET THIS BAD BOY WORKING. THANKS A MILLION FOR GUYS FOR TRYING TO HELP.

I had to also replace another 5x 1uf capacitors as well to fix the problem...
just replacing the 10uf ones wasnt enough

Thanks digi_brat. Well I sent both the 1 and 100 capacitors to my man doing the repair for me but for reason he chose not to replace the 1's. He gave me a reason but I forget what it was but I just figured he knew a lot more about it than me. I live in TN and he lives in CA so the round trip postage is quite a bit. I know of no one locally that could do this for me so if someone a bit close to TN that replace the 1F capacitors for me I would really appreciate it. I will gladly pay you for your time and of course would pay for all postage charges. Please let me know. Thank you all very much for trying to help me get my 805 fixed.

I stumbled upon this thread looking for some reviews of receivers. My 606 dvd input stopped working yesterday. A few months ago game input failed. I'll be heading to radio shack shortly to try fix this myself........

i'd gladly do it but as im in the netherlands postage and the time to get it sent around would take ages. i think you'd be better off taking the info on this forum and give it to a repair shop and have them solder everything for a few bux.

Im having the same problem w/ my tx-sr805. Im testing the voltage on each board as I tear the sucker down board by board. Its going to take a while, but I have no $ to buy a new reciever. Ive gone through the HDMI board, power board, sirius board and the coaxal/am-fm board. Nothing blown so far. Ill keep you updated w/ pics if I find a problem.

Oh, and as a few ppl on this page mentioned, the white connecter w/ the black wires on the HDMI board, DO NOT try to remove the white piece. Push straight down (into the board)(w/ the flat head of the screw driver or pliers), on the white piece. Then pull up on the black wires and they will come out of the white piece. You will see the bare wire at this point. Hope this helps anyone that was confused like I was

Thanks, look forward to your findings.

CZ_THE_DAY - you're a life saver My TX-SR576 had gotten to where it would sporadically completely drop the HDMI signal after it heated up for an hour or two (slightly different from most people's complaint). I simply replaced the six caps you originally mentioned with 100mfd/10v @ 105'C and I ran it practically all day yesterday with no receiver drop-outs at all!! I didn't get a chance to install a fan yet, but I made sure that my cabinet was better ventilated by cutting a big hole behind the receiver in the fiberboard webbing at the back.

Thanks again!!

Find service manual. There is a diagnostic procedure for protection triggers described there.

I want to do this repair on my 606 but I've never soldered anything in my life.

I can't believe how many of you guys are perfectly comfortable with soldering.

I'm keeping my man card, though.
