Mitsubishi Error Code 57

post #1 of 8
Thread Starter 
I have a Mitsubishi WD-65837. A couple weeks ago, I started getting an error code 57. I took out the electronics and gave them to a friend to look at, since none of the caps on the ballast looked bad. He said a couple on the main board tested kinda iffy, so he changed them out. Everything looked fine on the ballast. I still get an error code 57. He suspected a faulty chip on the main board, but could offer no further assistance.

He's suspecting the main board, which is a little tough to find. I don't really want to buy a ballast if that's not the problem.

Advice?

Three prossibles (read to me from the service manual - no I don't have a copy or access to a copy).

Error Code 57 means Ballast communication problem (ballast to chassis)
Possible causes:
1. Loss of 340V from PWB-POWER to Ballast (Loose PL or CJ1 connector);
2. Loss of communications between PWB-MAIN and Ballast (Loose FB or CJ3 connector).
3. Ballast Failure

Right, the information I have, I got from the service manual. I was hoping to hear from someone that had experience with these things to gauge how likely it is for the main board to have a chip failure. Also, how likely is it for the ballast to be bad when there doesn't appear to be any damaged components and the caps on the ballast tested fine.

Most of the suggestions relate to security of the connectiors between boards not caps or chips, you may already checked those but you did not say so.

What with the ballast fails? My electronics guy is looking at the TV today and I'd like to have some guidance.
