Re: Onkyo HT-R690 AV Receiver Front Right Channel Not Working

Come on dudes someone has to know where I could check from here. I would like to not throw this out if possible. I have been doing research and watching videos on troubleshooting, but still having issues. Please help.

Look at PDF page 7 which is the Block diagram, you will see FR comes out from IC Q4001 pin 21, FL pin 23.
Those two output signals are fed to the connector P6600B (PDF page 11).
So those are where you need to trace and find out if you have audio signals there or not.

I repair TV's all the time not knowing ohms law and not knowing schematics. I guess receivers are different.

No it is not different. To repair TV's then you must understand circuitry? If not you must be guessing at what is wrong, then you are lucky you have not zap yourself with a good amount of voltage. Ohms Law explains how voltage, current and resistance is represented in a circuit. It is so basic and simple. From Ohms Law power can be understood.

Thanks BudM for the page correction. I had just look at the first diagram and did not see the small letters for the model number.

Correction! PDF page 10, NOT 11, disregard about the connector P6600B in post #22.

Thanks guys I'll have a squiz at it when I get home from work this evening and I'll post my findings.

I'm looking all over the place for Q4001 I can't find it.

PDF page 7 & page 10 Board # BAAF-0621

Re: Onkyo HT-R690 AV Receiver Front Right Channel Not Working

I don't see any board by that name. What's on this board? Is it the HDMI board?

[sfernandes]

Re: Onkyo HT-R690 AV Receiver Front Right Channel Not Working

All my boards start with bchdm

[sfernandes]

Re: Onkyo HT-R690 AV Receiver Front Right Channel Not Working

Well not all, but I looked at every board I don't see any with the name baaf

Re: Onkyo HT-R690 AV Receiver Front Right Channel Not Working

Audio input, it has connectors p5502b, 5503b, 5504b, PDF page 10.

Re: Onkyo HT-R690 AV Receiver Front Right Channel Not Working

Ok found it. It's called BCAF 0621 no wonder I couldn't find it. I'm happy I looked for the numbers instead. So I'm assuming this IC is in the bottom correct? If so how is it possible to probe it playing audio with the whole unit apart and all boards disconnected?

Re: Onkyo HT-R690 AV Receiver Front Right Channel Not Working

PDF page 2 Exploded view # U0010.
PCB Part list page 53, Q4001 listed on page 56.
You NEED to look at the service manual.
I looked at 130 pages.

Re: Onkyo HT-R690 AV Receiver Front Right Channel Not Working

I have the manual open on my laptop next to the unit.

[sfernandes]

Re: Onkyo HT-R690 AV Receiver Front Right Channel Not Working

So what are you saying? I'm not understanding. I'm looking at the manual at the pages you told me.

[budm]

Re: Onkyo HT-R690 AV Receiver Front Right Channel Not Working

Well look at page 2, page 7, page 10, page 53 and see how they all are related to each other.

Re: Onkyo HT-R690 AV Receiver Front Right Channel Not Working

Is this ic on the bottom? Do I have to strip this thing down? If so how would I test it? Build it on my carpet with no chassis?

[sfernandes]

Re: Onkyo HT-R690 AV Receiver Front Right Channel Not Working

I'm looking at those pages I can't see any relation. The first page shows how the unit comes apart and the others is a block diagram and a schematic.

I do not know I do not have the unit or the board in front of me but you now know where the board is so now you need to figure out how to get to it to look for the IC and how to get to it to test it.
If it is going to be easy for beginner then every body can do it, but it is not for beginner.
