    Philips 37pfl560: Yellow picture

    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.

          Its probably 37pfl5604h, the sticker is hard to read. And i can confirm, after disassembling the screen, the backlight seems very "warm". So i dumped the tv to the recycling center, and i got lucky, someone was about to throw a 55 inch LG with bad leds. I guess its a win for me

              I was watching a web page selling a CoB led strip where each 50cm are fed with 230vac (it can be cut every 50cm), i think there's possibility to hack these to be fed by a tv set built in regular inverter.. with more voltage.. eventually the inverter output can be trimmed a bit with feedback hack...

                  inverter current feedback is a difficult chapter by the way..

                      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.
                      ...

                      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!​

                      Philips 50PUS7363/12 Backlight but no picture
                      by groomit
                      Hi,
                      I'm having trouble with above mentioned TV. Bought it defect.
                      Picture was heavily compressed around the horizontal axis. Fiddeled and tried different things (mask clock lines, swap T-Con). But no difference.
                      Then I identified a heating capacitor on the left hand Signal-PCB (?) below the display. Replaced it by hand soldering. Checked for shorts afterwards. But now the screen stays black.

                      I can see backlight, but screen stays black.
                      What I've tried:
                      - Disconnect right side cable from T-Con -> same (backlight but no pic)
                      - Disconnect left side...

                      SAMSUNG UN55KS9000F picture fades then distorts into vertical lines after 20 seconds
                      by JJAAMM
                      This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.

                      Problem
                      TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode...
