Question about Mitsubishi WS-55857 55" Rear Projection Television

1 Answer

I have the bowtie effect on my picture that cannot be fixed in the advanced menu. For awhile it had gone in and out but now it remains. Sometimes there appears to be angled lines that flash on and off too. Any thoughts on how to repair? - Thanks

This is a common problem with these sets and is usually the convergence IC chips. The soldering joints on them become loose over time as they heat and cool and eventually lose connection. This usually just requires the chips to be re soldered. If it is not fixed promptly, the IC chips then go bad. If you can give your TV a good WHACK! and the problem either goes away or comes back, the chips are probably just loose. A shop will charge about 250-300$ for this repair, or you can order a kit and do it yourself for about $100.

If you can quickly get to menu before picture goes blank, then go picture / backlight / set backlight to minimum and it will work fine.

Rear Projection - Color convergence/bowtie effect


Hi


Thanks for using FixYa. From what you have described it seems that you have to replace the convergence IC and also check the power resistor, if values are not exact you have to replace them. These ICs are located behind the black heat sink; you can see once you open the back off the TV. Also, the convergence board should be checked for cracked solder joints and please make sure to check the resistors as if they are shot the ICs might blow again. All this is only recommended if you have electrical expertise and know how to solder/re-solder components, if not then you should get this done by a professional. The typical cost to get this fixed by a pro is around $250-$300. Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

3d image/sinking effect


This is a convergence problem. Ther are either bad connections at the convergence ICs or the ICs are defective. If you can solder, you can repair this yourself. Try resoldering the pins on the ICs first. If that fails to resolve the problem, replace the ICs. These ICs are large, black and attached to a heat sink. They should be marked STKxxx. Figure on $20 for each one. There will be 2 of them.
Keep us posted.
