    MY SONY 42" REAR PROJECTION TELEVISION STARTS LOOSING COLOR AND THEN GOES TO AN ALL BLUE SCREEN THEN BLACK BUT YOU CAN STILL HEAR THE VOLUME AND THEN IT TURNS OFF BY ITSELF. I MADE SURE THE TV AND PLUGS CONNECTED TO THE TELEVISION WERE DUSTED OFF AND PLUGGED IN CORRECTLY. I CAN TURN THE TELEVISION BACK ON AND IT DOES THE SAME THING AGAIN.

    Are you talking about opening the back panel?
    And what do you use for the screws, if not a screw driver?

Mine just did the same thing.  Except for it was green instead of blue.  The service manual states 8 flashes from the light stands for an overvoltage.  After reading the manual for a bit I realized the bottom row of 3 adjuster screws from behind the speaker grill adjust the output for the red, green, and blue colors.  BEFORE OPENING ANY TV OR MONITOR PLEASE KNOW THAT THE VOLTAGE INSIDE CAN KILL YOU EVEN IF UN-PLUGGED so please be careful and only adjust what is mentioned here.  I un-plugged the tv, removed the grill and the board covering the internals, and carefully turned the 3 adjustment screws all the way down.  I then waited about 10 minutes (don't know if this made a difference).  I turned on the tv, turned the channel to an auxilary input (for a black screen), and slowly raised each of the 3 bottom screws one by one up clockwise until i could see a faint green, blue, or red line (depending on the screw), and then turned each one back a hair until the screen was black again.  Only adjust one at a time, the order for colors are blue, green, then red from the left.  I hope this fixes your problems.  Be careful when working inside a tv,  I suggest not using a screw driver to adjust the screws due to the possibility of it slipping and someone getting hurt.

My Sony KP-46WT500 screen shows the tv image in blue only for a few seconds, then it goes completely blank (as if it were off). Do I need to replace the bulbs?


It is rear projection TV that use 3 picture tubes of red-green-blue to show color picture on tv front screen.
Do you see standby red light blinking when TV shuts off after showing blue image for a while?
If red standby light is blinking, please count it how many times it blinks, there would be 3 seconds pause between blinks so count pause to pause and post it here to find out possible solution.
Thanks.

Code 22 indicates that your set is in shut down due to what is called Short Protect. The most likely cause is the Converge Ic's drawing too much current and opening one or 2 fuses. Normal repair cost varies by area and servicer. Expect 250 to 350 plus the service call. I normally do this on site.

Green flashes then tv turns off


or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.
