Pcj522r I think I do now. They were facing the side of the cabinet so you can not see them without taking out the board. Do you have to solder them in?

No video. audio comes through crystal clear. model #vs6140

A very common problem in older Mitsubishi sets is bad solder connections develop.

If bumping or jarring brings back picture you are going to have to get the entire chassis loose----it involves getting the chassis unbolted from cabinet, releasing some bundled wires and lifting chassis up so bottom is facing rear of set.

Then you take a good look in power supply and other areas for any "ringed" connections: connections that are cracked loose and not soldered solidly.

The hard part is getting the chassis loose; usually in this case I find four or more loose, or poor connections.

What happens is from age the board expands and contracts and some parts that produce more heat crack/break loose solder connections.

Let me know if you have questions.

That sounds like a solder issue on one of the CRT drive circuit boards. Check the CRT boards for bad solder joints especially on the socket connections.

Tv won't power on

Big Irish,

I saw how close to the bottom of the cabinet the main board and
all the soldering connections were and chickened out on repairing it myself. I found a local fixit shop who fixed it for $160

Thanks for the information though. I appreciate your suggestions.

If you are good at soldering simply replace the Ic's STK392-040 there are two, if you simply want to replace the entire board the part number for youre set is AA95-00055E and it's about $250.00
