I too, took off the back of my Sony TV after I started getting red and green shadows (called retrace lines) around words and people; and blew out all the dust inside hoping that would help. Ironically, I discovered that most problems with rear projection TVs are due to a malfunction located in the bottom FRONT panel, accessed by taking off the front speaker panel and then a wooden panel after that to access the circuitry, specifically this little black box with 6 screws on it. Go to www.SomeLifeBlog.com and this site has photos how to take off the front of the tv and instructions how to fix some common problems that repair people will charge you $300-500 to fix. This man, his instructions, photos, and website were a godsend. Good luck.

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.

Tv Problem


Sony TVs generate an error code. The front panel LED (red) will flash anywhere from one to eight times which can isolate the problem circuit. It is not always accurate.

If you have a test meter which can read DC voltages and resistance in ohms, you can locate the problem area. If you lack the expertice to do so, contact a sony authorized servicer. If you have the ability, start by checking fuses on the "G" board ( power supply board) and the "D" board or deflection board.

A major problem area in this TV is the convergence circuit. There are six fuses around the convergence output ICs on the "D" board.

If any are open, replaces the output ICs.

Minium is the green picture tube need to be replaced, if you can take the front cover and access panel off there is a control with 3 focus and screen controls.
you can adjust the 3 screen controls to possibly get a little more time out of it before the crt's need to be replaced. careful if you turn them down too much there will be no picture, and if you turn them too high the tv will go bright and shut off
