Question about Panasonic PT-51HX41 51" Rear Projection Television

1 Answer

Panasonic TV Shuts off by itself

I have a 51" projection Panasonic tv (model PT51HX41 about 5 years old) that shut off itself. The only way to reset the tv is to unpluged it and repluged it. Sometimes it works for an hour other times it works for 30 secondes.

This started after I replaced the convergence ICs (STK392-110). Checked all resistors OK. Any ideas?

    I also have a Panasonic
    (model PT51HX41) that shut off itself. Sometimes it works
    for an hour other times it works for 30 seconds. I also replaced the convergence ICs (STK392-110) and the set worked great for about 6 months.
    Now it shuts off anywhere from 30 seconds to several hours. I have notices that it is show how heat related. When the temp in the house is cold it shuts off more often. If it's a warm day and no air conditioner on the set plays for hours with no problem. Thinking may be a bad solder joint ?

    My Panasonic 51" projection TV is also shutting off by itself. If I unplug it and plug it back it, it will turn on for maybe 5 seconds before shutting off again. Will not turn on again without repeating process. Does anyone know why???

I had the same problem , Good sign of a cold solder or cracked trace.

On my PT51HX41 after a long check with a magnifying glass I found the problem on the main board just below the AC daughter board there is a Blue rectangular box (relay R801) and it had two cracked solder joints.

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.

Sometimes, in the Panasonic projection sets, one of the convergence IC's shorts out and draws so much current that one of the resistors next to it glows red hot. The computer senses the extra current and shuts the set back off. This is quite an easy problem to correct, but the set should be serviced by a qualified tech familiar with panasonic projection sets.
