Question about Mitsubishi VS-50705 50" Rear Projection Television

1 Answer

Mitsubishi VS 50707 ( not 705)

The problem is a unstable picture broken by several horizontal bars for half an hour or more and then the problem ceases and as long as the unit is left on, the picture remains steady.

A service man suggested the horizontal hold could be the problem wacked the tv a couple of times and left after estimating about $500 to fix it.

Is this something I can handle myself?

    While turning on television during initial start up, screen jumps horizontally for at least an 1 hour to 1 1/2 hours. Then returns to normal until next shut down start up, then repeats.

I have the same TV built in 99. My problem is similar but the vertical hold gives out when the tv warms up about 5 minutes. I will attempt to locate the vertical hold circuit and replace any parts I suspects may be the problem. I suspect a cap is leaking or transitor around IC700 is degrading when warm.

I have sound but no picture on my tv


This is a popular question. Most of the time you either need to make sure all connections are not loose or just need to turn off your tv and receiver and unplug. Wait for 1 minute then reboot.
I recommend this short video as it walks you through some diagnostics for other possible problems.
