Question about Mitsubishi VS-50707 50" Rear Projection Television

1 Answer

Mitsubishi VS-50707 screen is jittery when it first turns on

I have a old big screen back projection tv. It used to work great but now the picture is jittery until it has been on for 1/2 hour to a hour then the picture comes in fine. Sometimes the tv works fine when it is turned on and a while later the picture becomes jittery.

When the tv is warming up a line that is broken up showing three different colors as it goes across the screen occurs. Then as a picture starts to come into focus the picture starts to move up and down (jittery). The line only happens at the top of the screen. The screen is not scrolling.

I understand electronics but I do not service tvs. I have the manual that came with the tv but it is not a repair manual. I have no schematic for this tv.

The picture tubes are warn out or the deflection circuit is failing. The power supply is struggling to fire them up. Takes a lot of power.
Some TV shops have the know how to replace the tubes. About $1000 parts and labor.

If the picture looks like a 3D then you have a convergence failure.
I would suggest to visually inspect the STK Ics for dry or crystallized solder joints.

The screen doesn't come on. You can hear the tv turn on, but the picture is not there.


try resoldering the vertical output IC sounds like the CRTs are blanking due to vertical deflection. this model is famous for cold solder on the vertical output.
