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

1 Answer

Green screen... I apologize because i may not know the technical terms, but i just bought a 57" sony rear projector tv (about a year and a half old 1080i), and the screen will flash green a couple times, and then about 10 seconds later, the tv just shuts off. Now, after a couple minutes, i'm able to turn the tv back on, and sometimes the same thing happens, and yet sometimes it works perfectly. Please help with the problem and if so, how much it would it cost me to fix it :( ??? Chris

Sony rear projection screen is red then tv shuts off

Can be 1 of 2 things. 1st the red tube just needs the voltage to it turned down. In the front of TV (you have to remove the lower front half of TV to access it) is a plastic square with 6 knobs. The from left to right top knobs control focus for blue,green red. The bottom knobs control voltage to each tube in same order (so lower right knob for red) turn SLOWLY to left to reduce voltage until excessive red and lines go away. If you over turn left or right set will turn off. If that does not fix it or if lines reappear then option 2 is that red picture tube is failing outright and needs replacement.
