Question about Sony KP-57HW40 57" Rear Projection Television

1 Answer

Kp-57hw40 screen goes bright red or green then powers off

I have this problem posted already, but am looking for the info that Sony extended warranty until Aug 08. I called Sony, got the normal commentary of being out of warranty. The pots on front work to remove the lines, not necessarily fix the powering off situation. I can't figure out whether i have one or two or zero crt's going bad, since the problem switched from red to green. Originally it always flashed bright red, now after tinkering, it goes bright green. TV still comes up when re-powered and has a great looking picture.

Sony rear projection kp-577hw40, screen turns red after being on for 10 minutes


This model and some others had bad picture tubes that are no longer available---there is an option here.

If screen gets bright red, green, or blue set will shut down as it detects too much current being drawn.

Seen over 100 with this issue--what can be tried and usually will help is a physical adjustment inside the set.

No parts to replace and takes about 15 minutes to do.

I can tell you how if you want to know.

ITS PROBABLY THE RED PICTURE TUB (CRT). IT LOOKS EASY TO INSTALL, BUT YOU NEED TO MAKE ADJUSTMENTS TO THE SCREEN ONCE IT IS INSTALLED. THE PART IS $3OO. TRY TO FIND SOMEONE TO INSTALL IT FOR $150 OR LESS. HERE IS A WEBSITE TO HELP YOU MAKE ADJUSTMENT IN THE FUTURE ON YOU OWN.
