No picture for a while i would turn the tv on and the picture would shut off after a few seconds. i found an adjustment "box" in the rear of the tv. after turning the color knobs down i was able to keep the picture from going out. but now i can't get any pic out of it.

Picture went out and red light on the front by power button is blinking. When I turn TV on I can hear sound but no picture,, then TV turns off automatically after a few seconds.


Hi,
It seems problem with low screen voltage to three picture tubes in this rear projection tv.
If standby light blinks 5 times after three seconds long pause then adjust screen volts of each picture tube to solve this issue.
Screen volt adjustment requires expertise and job of professional so please call local tv repairman to help you.
Thanks.

Green hue on KP-43Ht20 Sony rear projection tv


Behind the front cover you will see a little plastic box with six phillips headed dials. They only move 180 degrees. The three on the bottom control color richness and the three above them control focus. Turn all three of the bottom ones to the left while the TV is on, then gradually turn them to the right until you get the color you want. NOTE if any one of the three bottom dials are too far up the TV will shut down and will continue to turn off after about 10 seconds after start up until the offending dial is turned back a little.

Tv wont come on


You may have some type of short INSIDE of your TV .Your TV is trying to turn on and RESETS itself to try again. If you have an EXTERNAL [black box],(usually means power supply, power adapter,etc.) power supply, that!! could be at fault. not giving the proper voltage, current, causing the machine to fault. If you can exchange a known working power supply to see if that is the problem.
If you don't know what you are doing, don't go inside of the TV. There are circuits that can hold a charge of electricity that can & will hurt you.

No picture, hear sound, television will shut off after a few seconds.


Lamp life is only a few thousand hours. Hopefully its only the lamp that made to noise. Don't turn on again until lamp is replaced.
