SOURCE: 55 inch mitsubishi rear projection tv red lamp out of adjustment

Have convergence IC's replaced. I believe this unit uses STK-392-570 convergence IC's Only one has gone bad but replace them both, because if one has failed then the other is not far behind, for Blue and Green. One handles Red, One handles BLUE and Grn. There are only two of them in the set, They are the two largest IC's in the entire set.

Jvc i art pro doe not turn on


The clicking sound is the TV trying to restart itself. It generally attempts this several times before giving up. The blinking code indicates the type of error (error codes are documented in the manual for the TV). The most likely cause is a burned out bulb, but could be something else.
If it is a bulb, it is usually replaceable without a service technician, and at a cost far less than $450.
Good luck.

Somehow you have turned on closed captioning in TEXT mode. Navigate the setup menus to find the closed captioning options and turn it off.

That should resolve the problem.

Tv turns off by it self


Ours 60" (60P8342) turns off after a short period of time also. My husband researched it online. The cheap solution he was told to try is to unplug the TV (or plug into power strip and switch off) when you are done watching it. A computer board inside over heats and it's a protection mechanism for it to turn off. Otherwise, it's over $100 to fix the computer board.
