PANASONIC PT-51DX80A hello, my buddy has this tv and i am electronic smart but looking at other posts it lloks like we have a bad resister on the board but i will let you decide that, problem : i went over there to look at tv (had great picture) i asked what the problem was and he says sometimes the red horizontal moves over 1" to the left. so i watched it for about 20 mins tuned it off and then on and it did it. so i go in the menu and try to adjust the convergence and all colors work except the red, the red will move un and down but not left and right. thats the only problem with the tv set, thanks for your help!

Normally, the main cause of this problem is the solder connection under the convergence IC's.
You would see rings around the legs that have bad solder joints.
My shop would replace both of the IC's.
I don't have a schematic in front of me, but, I'm pretty sure the IC's are STK392-110. We use the STK392-150 in place of them since they are a heartier IC.
When replacing these IC's, remember to use semiconductor compound on the back side of the IC when placing the parts against the heat sink.
Any questions, respond to this post and I will reply.

Panasonic PT-61DLX76-K TV, no picture, red lamp indicator flashes once every five seconds. Bulb looks okay visually. Panasonic says bad ballast I need confirmation and service manual.


Hello.
Lamp should be replaced in average every 2.5 years. Bad lamp could look OK but it is not.
Replace the lamp first if it is older than 2-3 years. You have to do it in any case. If new lamp will not
work, only then you can start thinking about ballast replacement.
If you are OK with the screwdriver and you have technical skills you don't need service manual to replace ballast. You will need to remove rear cover and locate it near the lamp. It is not too hard.
Regards.
Russ.

It looks like a problem with a tube (projector light) I suspect the green one. Pay attention to flickering on the lights and post me the results.

Your lamp needs changed, after removing the lamp it might still, look good, but it is bad. After a while the bulb builds up a internal resistance, and it makes the TV hard to start, and then it gets to the point where it will not come on at all. You can go to www.partstore.com and get a new lamp, and that should take care of your problem.

My 52" PANASONIC PT-52LCX35 does not come on after a power surge went off due to lightning. I press the Power Button to turn TV on, but green light just blinks a few times then stop without any sign of...


Remove the Lamp and look for a white fog inside. It is bad if it looks that way.
If thats not it, Call a good TV Tech to troubleshoot the problem. Lightning can do about anything to electronics.
