    ditto - Mitsubishi medallion 65", comes and goes. Seems especially common during warm up. Any idea as to where to get parts and manuals?

    I have the exact same problem on a WS-55807. Goes away after a couple of minutes but was progressively getting worse. Read the post on the brown ground wire by HOSER67. Got to the wire, it was a little black looking like it might be arcing. Wiped the ground screw and area with alcohol and put it back together. Problem solved!! HOSER67, you pinpointed the problem on the money!! Thanks!!

On the middle circuit board there is a tall metal wavy rigid plate.on the back side middle screw is a ground wire(light brown) that is loose.very difficult to reach unless you disassemble unit.

Cheap Fix?


I will strongly advise you to replace the two STK392-120 as a pair. and this will cure your bowing picture problem. You may need to re-converge your set. best of luck.

No picture have sound


sounds like your IC's took a dive again. Did you change them or a shop? You have to also make sure that when you change the IC's that you put plenty of heat sink compound on the back of the IC's and do not use the cheapy IC's that you can get for 20 bucks or less as I have found they do not last. This convergence board should be available as a complete board. Good Luck

Picture Distortion


you have a convergence problem.. If you understand how this works then you can go into the set find the convergence ic's and replace them and sometimes you need to do some alighnment as well. Its always best though to let a service tech do a job like this as he will have all the proper equipment to adjust and troubleshoot the set Good luck
