Question about Mitsubishi VS-50705 50" Rear Projection Television

2 Answers

VS-50705 Picture shrinks to the top of the screen. Now I have it in a room that is 60 degrees, no problems!

I am asing this question even though I have read as few answers. I am asking because of the area the TV in in now.

The screen was shrinking to the top. The next day I would turn it on and sometimes it would be ok for a while or shrink right away. The last year I have left the Tv in a room that is roughly 60 degrees. I turned it back on, plugged a DVR into input 1 and it has been working fine ever since. I have left it on for 48 hours and it still works.

I am assuming if I put it in a warmer location it will not work again. I would like to save it for the garage if possible.

With the details I provided what Cap could be the problem if it is a Cap causing the problem?

Any thoughts would be great. Thanks! AL

This is not a cap but a conversion problem, the conversion IC chips control the horizontal , vertical ,and color alignment , but there is also some resistors on the conversion IC's that have been causing the set to look like they need the conversion IC's, so you could check there values and maybe only have to replace a resistor
here is an example of the STK conversion IC click here

Now a days, TV don't have replaceable parts any more. the next best thing is to replace the board. it could be the HV, horizontal or the valiance.

I have Model: DM30A which constantly freezes up even though it is on a three foot high table and the temperature never goes below 60 degrees


The unit freezing up doesn't surprise me at all. If the temp in your room is 60 degrees then the temperature of the air will be around 40 degrees and the coil is about 20 degrees. Your expecting to much, the tempature is to cold to work properly.

I have a Mitsubishi Rear Projection tv (vs-50705). The picture shows a concave image on the top and bottom of screen and the edges go off the screen. I have red blue and green ghost images on the screen...


Well, you did the right first step. However, when the convergence outputs toast up they sometimes cause other problems. First would be the fuses that supply them voltage. These are pico fuses back in the power supply. Second would be open supply resistors that have opened up because of the excessive current draw caused by the whacked out convergence amps. When changing the outputs doesn't solve the problem it takes the repair out of the realm of the do-it-yourselfer. My recommendation is to let a professional take over.

The Picture on my Mitsubishi vs-60805 "shrank" then disappeared


it isnt worth it, your verticle diflection is out, that board is about 3-4 hundred, and you would probabily need a service center do it(messing with like 30000 volts)and they will probabily charge around 200

Good Day, tree64;
More than likely the convergence problem the TV has wont be resolved by adjustments. In your situation, moving TV, the problem most likely is poor solder connections on the convergence IC's. They are large devices attached to very large heat-sinks, and have numbers on the IC'c like STK 392-560.
If no poor connections....replce.
Good Luck, big IRISH.

Try replaceing capacitors C2C52 10uf 50V capacitor and also C2P05 100uf 16V capacitor. these are both on the signal board. It that doesnt correct the issue replace IC2P01 which is the 9volt regulator also located on the signal board. That should take care of your problem

No Blue. Horizontal Lines.


Not to me, but it also depends on if you could do this yourself or not. And the area you are in sometimes is responsible for the cost being high.
