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.

Sony KP-46WT500 Red, green and blue lines appearing on screen


your convergence IC;s are out, they cost about $40, if you know how to solder, you can do it your self, if not , I would try to find somone that can, service centers charge about 4 or 5 hundred, after you get the new ones, there easy to find on the board in the back of the tv

You need to replace both STK392-560 convergence ICs and some of the 4.7 ohm 1/2watt resistors. You can get replacement ICs and resistors at the following link with free instalation instructions.

Red hue on TV


I have the same problem. Researching a replacement lamp. After 5 years the lapms expire and it is the most likely failure. Confirm with a local service person using the Sony website to locate a service center.

Replacent in not difficult but the bulbs are >$200. Cheaper than a new TV.

SONY KP-46WT500 Arched red lines appearing, mostly noticeable when the screen is dark. I have heard there is a simple fix for this problem. I read something needs to be tweaked with screw driver, but i do...


After all the screws are removed, the panel pops on . They use plastic dowls inserted in rubber. The brightness may need to be turned down on the color that has little lines appearing. The brighness is on the picture tube board on each picture tube. Good Luck
