    Philips S42SD-YB05 No picture

    I have a Philips S42SD-YB05 Plasma, when the power cable is plugged in(I dont have to turn the tv on by the power button) I get a few green LEDs light up on power supply and on the logic board/control board(LJ41-03075A), a couple of seconds later the screen lights up, but after 20-30 seconds the tv powers down and wont turn back on without unplugging and plugging the mains back in.
    I'm sure I read that the logic board(LJ41-03075A) is an issue with these tv's but how can I determine whether or not the logic board is the issue?
    I have checked voltages from the power supply and all appear to be ok. I have also tested 4 voltage regulators on the logic board and again they all appear to be ok.

      Philips 55PUS6704 no picture, backlight ok
      by Patrick501
      Hello,
      I'd like to repair a Philips 55PUS6704.
      It turns on and you can see the backlight, hear the sound but no picture.

      When I disconnect one of the T-con cables, half of the screen turns white.
      right cable disconnected= right side white
      left cable disconnected= left side white

      When I tape like 6 or 7 pins of one cable it looks like the picture attached. I already tried another T-con board without success.
      There are no shorts on the the mainbaord and the two lcd panel boards...at leat I couldn't find any.
      Also you can notice one single...

      Philips 58PUS7805/12 showed no picture; after T-Con replacement, shows halo
      by Rauni
      Hello, this is my first post on this forum, and my first attempted to repair a TV.

      My Philips 58PUS7805/12 stopped working recently. It is not that old, about 5 years. We were on a trip for a few days and when we came back, it had stopped working out of a blue (Perhaps our house was hit by a lightning strike? Don't know.)

      Read from a guide that I should test if the screen shows picture with one of the T-Con cables disconnected. Did that, it showed perfect picture (first on left, later on right side).

      Read also that we should test what happens if we...

      Philips 243v5lhsb00 Monitor Picture too bright
      by Schwoin
      Hey everyone,

      the picture on my philips monitor looks way too bright so that black appears grey and colors also seem too bright.



      While i tried to tilt the screen a little bit while it was displaying a picture, i´ve noticed, that there appeared some purple pixels. In the following picture
      you can see them on the top half of the photo.



      At a certain point during the tilting, the picture looked normal again but as soon as i laid it back down, the purple pixels were gone and the picture was bright again.

      Philips 37pfl560: Yellow picture
      by madyoyo
      HI.

      I have a weird problem with an old Philips 37pfl560 TV i put out of storage: the picture have a noticeable yellow hue, and its not caused by the settings (did a factory reset). I've never seen this before. I will try to get a photo with a real camera, with my phone its hard to see because of automatic white balance, but in real live the whites are really yellow.

      Anyone have an idea of what can cause this? Can CCFL tubes get "warmer" with time? This tv have several analog inputs,so its nice for retrogaming....

      No picture issue in Philips Chassis FTL2.1
      by charlesdutcher
      Hello,
      My Plasma Philips 37inch chassis FTL2.1 does not show picture. It automatically goes into protection mode after 30 seconds (red led blinks at 3Hz)


      Is there someone having any symptom like this? How to fix it?

      Thanks in advance!​
