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.

My sony projection tv model # kp-46wt500 has a green and red tint. how can i fix it?


Increase the current flow to the blue color gun. If it is not adjustable it will need replaced and this is a major repair. You can try to reduce the red and green guns and increase the output transformer for a temporary fix, but save up your pennies for a replacement. Have a tech look at it before running out for a replacement because the SONY is the better model projection televisions.

Blue Screen


Your blue crt has a short - you can verify this by unplugging the socket from the blue crt and powering up the set and you should see a yellowish looking picture with just the red and green crt's operating. You can try turning down the screen control pot (B) for blue with the blue crt on (just to the point where you no longer see retrace lines in the picture on a blank input)Sony has had a lot of problems with the crt's on these models and sooner or later all the crt's will fail - For a permanent repair all must be changed.
