Nobody thinks that is easy you just make it look that way  I still grumble swapping dead caps on motherboards. I just replaced a half dozen CPU caps and threw a drive in a yard sale HTPC, my son has a system with a wire less keyboard and I am out less than 40$ and half an hour.....
and he now thinks bringing dead electronics back to life is easy:-)
What was the AVR Mac?

It was a Pioneer VSX-94txh. I have bought and sold quite a few of these and the 92txh but mostly with minor issues. The symptoms were garbled display and no other functions.
I have a 92txh test unit that I use for repairing boards and don't use it for anything else. After repairing this 94txh and while testing all the outputs I noticed it had a USB port for thumb drive and a network link for internet radio, items the 92 does not have. I liked these features so I swapped this unit into my main system.

Nice work Mac, that looks like the work you were doing to my Denon board with the main IC. Too bad we didn't realize we needed the programmed version first
All in all, nice You have surely got some steady hands
Jask... Motherboard caps are quite the Pita, I've repaired so many of them though, that I have a fairly well developed technique. I can usually recap a motherboard with 20+ bad capacitors in about 10 to 15 minutes, all without the solder work looking bad, since usually that's the issue most have with motherboard work, they mess up the contacts where they are trying to remove the old cap and there you have a useless board.
I'll give you credit for working on them though, they are no easy task

That one really pissed me off. That should have been nothing more then a basic CPU but Denon had to go and do pin reassignment. Then when I contacted them for the firmware to reprogram it since it had simple onboard programming they would not give it to me. Then I have a guy who is denon ASC and they wouldn't give it to him either. That really turned me off to Denon and Marantz.
They were selling a 50 dollar chip (retail) with their programming on it for 125.00. Just another instance of dicking people over.

I agree with you there. For a $6000 unit they could and should have given the firmware up for it. Good thing McIntosh isn't owned by D & M anymore
Regardless of how much of a POS that Denon was, the second unit I bought and repaired is still quite a nice unit. Just as long as it doesn't go to hell so I don't have to deal with it

Had another interesting repair this week. Another one of my flat panels went down, number 3 or 4 in 3 years, lol. Glad I don't pay full price for these things.
Anyway, the tv lost all tuner function, both audio and video and lost audio on all other inputs. I'll skip the boring details of my troubleshooting process and just post a picture of the 1 bad part that caused the issues.
The first image does not show anything special other then a SMD part. The second picture puts it into perspective.
Oh, it's that speck to the right of the penny, lol.

Not an LG from around 2008 is it? Ive got one at work that shows no signal on composite video, yet it displays a half cut of the image from the composite video input when set to DTV Tuner.... Ive fixed 14 of these damn things now but I haven't looked hard enough to find an issue on this one.

No, this was a Vizio. You need to test the output of all the regulators on the main board and tuner board if it's separate. What's the model number?

Not sure on model number, im not at work today so ill have a look and post it up tomorrow
It has 2 separate boards screwed onto the flat metal plate inside the back plastic cover yes, although one is the power supply and the other is the mainboard with the tuner on it.
