Question about Toshiba 57H81 57" Rear Projection Television

1 Answer

Distorted Picture Upon Startup

When the TV is first turned on the picture is distorted and shakes (like a TV with poor reception). However, as the unit warms up the picture quality becomes more stable and clearer after apx. 5 min. and is back to normal until shut down and cooled off. The convergence IC’s adjustment’s respond to automatic and manual adjustments, so, I kind of feel the IC’s are not the problem (but, I’m not the expert). I did remove the printed circuit board to inspect for possible cracked solder area's but failed to locate any. The fact that the system performs great after a 5-min. warm-up is what bewilders me.

Any help is greatly needed and I thank you for your time!

Have a great Holiday!

Picture distortion in your rear projection TV is because of failure of convergence out ICs that need to be replaced.
Qualified TV tech will fix it under $150 or $200 and if your are good in part soldering in circuit boards and have electronics knowledge then can replace by yourself.
Required ICs can be purchased from Part Store.

in your tv there is a light engine ballast.that light engine ballast controls the colour /picture quality.that engine is got faulty and that needs replacement.if the picture with distorted also looks dim then there is a lamp that also needs replacement with lightengine ballast.but if the picture is distorted but bright then no lamp replacement only light engine ballast.
this is very costly issue to get replaced.near to $350 plus the service charge of the technician who replaces the component.
thank you for using fixya.

The picture is curved in at the top and bottom of the sides.

This issue is caused by the micro capacitors and the convergence module, the capacitors are part of the main circuit board, the job will cost around $600 to repair, better option is a new TV.
