SOURCE: lg 50 " plazma red pixels appering around top of screen

the actual problem is some of the components on some of the boards are showing signs of age (some of the values are changing slightly) this can be compensated for by adjusting your voltages (such as va & vs ) this take a little tech knowhow. or you can replace the y sus board but adjustments are necessary whenever replacing y or z control boards. hope this helps. i may know where to get boards if you need them.

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.

The tv is showing red lines on the screen.


These are retrace lines. The screen on the red tube is turned up too high. Inside the set there are 6 knobs. 3 for focus & 3 for screen. Turn down the red screen until lines are gone. These knobs are usually found by pulling of the front panel.

Sounds like the blue convergence IC s bad. They are relatively easy to replace if you can solder they cost around 10.00 each and you should change both the red and the blue.

New Sceptre 37" LCD TV does not turn on


I just got a 42" komodo by Sceptre, same problem, except "SCEPTRE" showed on the screen. I was sent a USB key program to insert in the service slot in the back and it reflashes the bios. This is old news for you but maybe new for someone?
