Panasonic pt52lcx15 TV. Recently, after approximately 5 min. The TV turns off. Is this some sort of power supply issue? Or, something else?


Try this.

Unplug the tv. take off the back panel. vacuum or blow out the dust with a can of compressed air (@ $3 at Staples). A lot of the projection tvs had a thermal sensor which would turn the tv off if it got to hot.

That is also a good time to clean the lenses. Be careful not to move them out of alignment. My tv worked like new after I did those things.

No picture have sound timer light blinks .when you turn TV on lamp light come on. Goes off. Tv have sound for 10 min TV cut off type 62" Mitsubishi dlp


How old is your TV set ? if you have not replaced the lamp in 2-3 years that is most likely the problem and need to replace that part.
This lamps now run from $40.00 - $90.00 depending on quality.

Mitsubishi projection tv picture and sound turn off but the power button remains on with no picture or sound turn tv off real quick and then back on and works for 2 mins then turns off again what could be...


Here's the basic troubleshooting:

  1. Make sure that no front panel buttons are inadvertently stuck in an "engaged" position.
  2. Disconnect ALL devices from the TV.
  3. Press the SYSTEM RESET button and hold for 10 seconds. Proceed if the problem still exist.
  4. Press and hold POWER and MENU buttons simultaneously for 20 seconds. Proceed if the problem still exist.
  5. Unplug the TV from it's power source for various times, ranging between 5 minutes and 24 hours.
  6. If it still shuts down, press the DEVICE and MENU buttons on the front panel simultaneously and hold it for 5 seconds to activate the Error Code Operational Check. The status LED indicator will then flash denoting a two digit code.
  7. Count the number of flashes then pauses for about a half second then flashes again. The first number of flashes indicates the first digit of the error code and the second number of flashes indicates the second digit of the code. For example, if the error code is "35", the LED will flash 3 times, pauses, then flashes 5 times. The error code is repeated a total of 5 times.
Please let me know the code you got and I'll tell where the problem lies and how to fix it.

Picture goes black mins after watching


Bad flyback transformer. It has a short in the winding making the Horizontal output transistor heat up so when its too hot the set goes into protection.

I have a 32 lcd wharfdale tv about 4 years old that keeps turning off at different times(nothing to do with 5 min timer)i would like to fix it myself,so as much info as poss please. thanx simon


Hi Simon.

When it goes off does the sound still work or is set dead ?

Does your set have A small transformer that plugs in to the mains or does the mains lead go directly in to the set ?

Tv cuts off and on.


Sounds like a bad SSB(small signal board) module. Better take it to a RCA AUTHORIZED service center.
