You bulbs are fine. You have a very common problem, your convergence circuit was going bad and now it has shorted all the way and the tv is going into shut down. You most likly need you STK's changed and possible some resistors. If you have a repair man do this for you it could run $300-$500. If you know how to solder and use a meter it can be done for under $100. Let me know if you need more help.

Thanks
Tim

My 51" Panasonic CinemaVision rear-projection HDTV


Try disconnecting all of your HDMI cables and plugging the power cord of the TV into another wall outlet. If this resolves the issue, you may have had a small power surge from either your wall outlet or one of your source devices. It is recommended to connect your TV to a surge protector if you haven't done so already.

Bad color then no power on 51'' panasonic cinemavision


Check the power light for blink code--usually if this model shuts down the power light will blink in a sequence--3 blinks a pause and 3 blinks is short protection--usually means a convergence circuit problem.

Jumping Screen 61" cinemavision


Hello dana1983165,

The problem you described is caused by poor voltage regulation in the High Voltage power supply. This can be caused by a defective fylback transformer, a defective focus block, a defective HV trippler, of the horizontal output transistor/damper diode assembly. I would first check the high voltage from the flyback to see if it was fluctuating, you can do this with a high voltage probe. The I would check the horzontal output transistor out of circuit with a transistor checker to see if it passes.

If you do not have equipment what you can do is remove the deflection/HV board and order a replacement from panasonic.
Look up Panasonic's web site and contact their technical support number and call them to find out the part number and have them order the part for you. If this fails try PTS at http://www.ptscorp.com

I hope this helps

Crack in screen Panasonic 42" HD Plasma TV


The only solution is to replace the TV. A cracked LCD or plasma screen is usually only good for Art..all the pretty colors around the crack.
