Onkyo HT-R690 AV Receiver Front Right Channel Not Working

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

I have never managed to put these together without a chassy(for measuring). I just measure the suspected components and replace the bad ones.
You should have said, that you want to take a brake from this unit for now and you will come back another time.
Bud is awesome on helping others, I don't even understand how he has time for all this.
Only for his commitment, I could not have stopped from a repair. I still have a Pioneer VSX-1122K, that we could not repair it and I'm still thinking about trying again. I don't like to give up, on anything. Right now, I try to repair a Harman Kardon AVR 1700(from two units, I make one).

Yeah, but the knowledge from learning is worth a lot more than that. Like I said some time I spend hours, days, or month on and off to figure what is going on, sometime I put it a side to clear my head and get back on it again later on.
You insisted on some one to give you the help and I did and I do not even getting pay for it and you worry about the money?
When I used to do repair work in the shop, I did lose money on the first unit when it is tough unit to work on, but once you figure it out, then when you see the same model again, then you know where to look right away because you apply what you learn form fixing the first unit..
Just like what info you get from Badcaps for free due to someone else has done the work and spends time to figure out, tracing out the boards and circuits just from the pictures provided and able to provide you the info for free so you do not have to spend hours or days on something you have never work on before.
Lots of people here have done that without getting any money and willing to share the knowledge.
Heck, I spent lots of times fixing something that is worth a lot less than my time spent, but the knowledge from it was worth far beyond.

I appreciate and apologize for your time. What's your PayPal? I'll pay you for your time. Let me know how much you want. I'm here to get help and make friends I don't want people to not like me and I would like people to help when I need. I didn't think I would upset so many people by giving up on the receiver. I also gave up because I wasn't understanding the schematics, the block diagrams nothing. I was looking at them and couldn't find nothing. The boards on the unit didn't even match with the part numbers in the manual. Also was afraid or getting hurt having to build it with no case to test. This is a receiver I'm sure those caps have quite the charge not like an LCD TV that takes bugger all stay away from led driver and inverter your golden in a receiver I dunno what to stay away from. So I thought about all that and I thought it's not worth risking my safety etc.

I understand what you are saying.
You can not control what another person does or says you can only learn from the encounter. As my father use to say you can lead the horse to water, but you can not make him drink.

A person has to make a living. Your right we do not know your circumstances. When you can afford the time sometimes breaking even on a project do not matter.
Not just for the knowledge you will gain but for customer satisfaction and repeat customers.
I understand BudM's point in asking a person how committed they are.
I think it was also important that you did apologize.

It becomes obvious that it is too hard for him to spend time after posting this:
'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." So I took the chance and look at 130 pages of the service manual pointing out how each page related to each other and where to test the signal, I suire spent lots of my times on this thread
Next when some one complaining about nothing getting help, I am going to ask first how SERIOUS the person is about trying to repair anything.
You need to pay your due, your times, effort, and commitment, otherwise you will not really learn anything.

I'm very sorry I spent your time. I do want to learn, but right now i have to clear out my room. Nobody here knows my situation so it's not fair to bad mouth me. If this would be an easy and faster repair great, but I can't spend that time right now I'm just to busy at the moment. I'm sorry I wasted your time. Sometimes the time it takes to fix something is not worth it as well. I got that unit for free it's only worth 200 if I have to spend many hours on it it's not worth it because I'm taking time from other things that will be less time for more money.

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

I agree, but the only issue is I have many many other things and projects to repair so right now i just don't have the time for a project like that. I have roughly 18 TVs to repair at this time and I'm the only one working on them.

The thing is by learning how to work on one device it crosses over to other devices. It helps to reduce repair time and it increases the amount of devices that you will be able to repair. You don't try and learn it all at once. Just learn one thing at a time. When that is learned you move on to learning something else. Otherwise you will only be a parts swapper.

Good luck with all of those in your to do list.

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

I also have many other things like headphones and things like that to repair.

56 Threads worth.
It could have been a great lesson to learn on how to troubleshoot the problems.

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

To late guys I gave up on it last night and discarded it on the way to work this morning so it's gone. I took the good HDMI board out and I'm gonna fix my bosses unit with the board cause his is faulty. Thanks for the knowledge guys.

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

I would check to see if the Muting Transistor is being turned on when it should not be or it has leakage resistance between E and C, see schematic PDF page 10.

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

I also tried banging the unit on the floor with good force while playing music and no change. Flexed the PCBs as well nothing

[sfernandes]

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

This problem could be as simple as a bad connection at a connector.

It could be yes, but in this case I'm sure it's not since before I got deep into it I used the eraser on the side of a pencil to flex, move hit and prod at all the components while playing music and nothing changed. I also flexed all cables while playing music and nothing. Also hit the relays etc no change.

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

Well, the service manual show you the signal paths and the the actual diagram of what is section is and how audio form the input gets to the output.
the bottom line is to understand the basic and how each component works, for example, transistor can be used as amplifier or as a switch, you have to be able to read the schematic to understand how the parts is being used. Once you have good base of understanding then it does not matter if you work on the amplifiers or the TV. You can fix TV power supply because you can see the bulging on the top of the caps but do you really understand each function of each section of the power supply to figure out why it is not working if you are not seeing any caps with bulging tops, that is the real troubleshooting. Replacing caps with bulging tops are easy, it is not easy when there is no clue.
What do you do if some one gives you the TV power supply board to fix that does not work and no sign of caps with bulging tops?

I get the service manual if it's not silk screen on the board but lots of times it is and I probe the voltages on the cables to find out what's missing because sometimes it could be the main board that's at fault and doesn't trigger the PS to come on

Yes I understand what you're saying.
