I have a Pioneer VSX94-THX AV receiver that is in need of repair. It's freezing up and then I can unplug it and plug it back in and it will work for a short time then shut down. Does anyone know anybody that can work on these and fixt them or is in now to old and junk?

No decent repair shop will take in any surround sound receiver. They are far too complex to work on, and most have problems with overheating chips that need reballing (google that!) , and that sounds like what yours needs. The unit heats up, the solder joints under the SMT chips crack, and you're DOA.

With a forum name like Munkynutz, maybe he's familiar with reballing? (sorry, couldn't resist!)
More reflow/reballing info here if anyone's curious:

Most people outside of EE's and techs wouldn't know what this means, until the Xbox 360 had issues ~15 years ago that was so widespread that it became something more were familiar with.
Either way, good luck!

Yep, the HP DV series were known for it as well. I actually sent one down to some repair place that I found on eBay, and they did a really good job for the $100 they charged. It worked fine after that for 3-4 years. Consumer receivers though.. not so much.
The oven trick has never worked for me, but it does for some..

You had better luck than I did with my PS3. I took it to a local repair place 2-3 times and they would fix the RROD for maybe 3–6 months. I eventually gave up and got an actual DVD player for my theater.
