    40 inch philips lcd tv model # 40pfl3705d/f7 no picture

    No picture, uncertain of sound because I do not have a remote with the tv to switch inputs ( or try to anyway)


    backlight does come on, its brightens at first then dims but is on.

    I toggled the ribbon cable on the t-con board to try and get a difference but no such luck, just blank screen.

    also makes a buzzing/hissing noise hard to describe, only happens when its on.

      Do a continuity test on the t-con fuse.

      Edit: I had the same issue a couple years ago with this particular TV. I soldered a new fuse on top of the old one instead of trying to remove it - totally acceptable: http://www.digikey.com/product-detai...5TR-ND/1206513

          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!​
