    Philips 47PFL7422D/37 tv picture faint

    I have a philips 47PFL7422D/37 that is having some issues. When powered on the tv shows the red led status light. It blinks 6 long and then 3 shorts.

      You say you have a "faint picture" so it is likely a backlight issue, so check the inverter boards. Do you get a flash of the backlights when you first turn on the tv?

      Error 63 (POWER OK). When this error occurs, it means
      that the POWER-OK line did not became “high”. This error
      is only applicable for TV’s with a LCD display.

      Ypu may have a fault on one of the inverter boards or a bad ccfl in the panel (or a poor connection between the ccfl and the inverter)

          I did have a faint picture but now it just shows the 6 blinks with the 3 following.

          Should i check the inverters then? I did replace the inverters because caps on the inverters were bad.

              Where did you get the inverters from? Are you sure they are good?

                  The inverter boards were ordered off ebay. Would bad inverter boards cause backlights to be faint or non working?

                      Are the backlights just faint or are they not working at all? The inverter boards supply the high voltage to the backlight ccfl's in the panel.

                          The backlights are faint. I will update with a picture to show what the tv is doing.

                              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!​
