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

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

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

[QUOTE=budm;684860]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.[/QUOTE

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.

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

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.

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.

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

Anyone have any clues what to check next? I'm guessing it's not relay related since the headphone jack is before the relay and the headphone jack has the issue as well.

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

Per block diagram, the Headphone jack is BEFORE the Front Left, Front Right speaker relay, so use the Headphone to see if you do get the sound of both channels through the headphone or not.

Ok I had a look and threw headphones same issue I just get the left channel but not the right. I noticed if I crank it to max with the headphones or even a speaker connected I get very faint distorted audio on the right channel. I'll wait to hear back from you guys on the next step.

I will check that and get back to you within the hour.

Thank you

I am sure their on online explanations of OHM's Law. This would be in a beginners course. You could learn this as it would help your understanding what you are doing. Kind of learn as you go. That is if you have a interest in learning this. Otherwise, you should rely on a technician to troubleshoot your equipment as you can get harmed with this stuff if you do not know what your doing. The Block Diagram I referred you to is not a schematic.

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

Unfortunately I don't know Ohms law. Maybe this is way beyond my scope. Would be nice if I could get it going. I will look at the schematic and see if I could make sense of it.

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

If you are going to repair these things you need to be able to read a schematic. Otherwise you will just be guessing. You could fix a problem and later on it could occur again because the cause of the problem was not fixed. Do you have any experience with OHM's Law?

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

The first place you would begin is on the block diagram on page 4 of manual that Bud M supplied. You will need to know what he ask you from that page. That is tracing from the output to the input. This is kind of like a flow chart.

Do you think it's possible you or someone walk me threw this?

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

Read the schematic is the start, you need to be able to read the diagram to be able to trace the signal paths on the unit based on the diagram, form output back to input if you know what that means.
If you are a real beginner and want to tackle something this complex it is not going to be easy for us to hold your hands on every steps.
So tell us what your experience is first.

I would say for something like this im a beginner. The most I have ever done is replace capacitors at board level. I cant even make sense of the schematic. Maybe I should throw the unit away, I dunno at this point.
