Hello, I have a RCA Model #F32650, Serial #C512C20GQ, Chassis #ATC113CA1, manufactured December 2002. The main circuit board fried and I am wondering where I can purchase a replacement board at a reasonable price. Thanks Brett

you just start from speaker first. if the speaker is out there will be no sound output from your TV. To confirm this, just plug in an earphone or headphone pin into the headphone or earphone socket , if provided, on the TV. If sound is available through headphone, it means that the sound output section of your TV has no trouble, but the speker is out. Replacing it with same type and number will resolve your problem. If there is no sound fron the earphone too, surely the sound output section inside the circuit board of your TV has the fault.
If so you have to open your TV. Locate the sound output stage, which can be easly locted through following the speaker wires. There will be an Ic [Sound Output Ic], normally screwed onto a metal plate, to radiate heat out when it works. Check for any bad solderings at the legs of that Ic by tuning the printed circuit board upside down. It is very difficult to locate loose solderings. i always do is, resoldering the suspected solder points by applying a little more solder. You also do this first. If it does not help, resolder the Ic out from the circuit board, and go for a same type and number. Replacing it will solve your problem. In some RCA sets, sound section is built out on to another board. Locate it and do the same. OK.
I already figured out that my flyback transformer was bad, this is an ongoing problem with a lot of RCA CRT televisions because RCA used very cheap parts in order to save them more money, rather than making there customers happy with good quality parts, and my TV was made in MEXICO, and that my friends is why we the American people are getting screwed. (Shame on you RCA)
This could cause a problem, because modern TVs and most other entertainment electronic goods, have a small kind of computer chip, but there should be a Reset button probably inside the set!
If you feel confident about computer chips you may be able to find the button by tracing the circuit.(Disconnected from the mains).
Another idea is if there is a small button cell or battery inside, then try disconnecting it for a day.
