    Philips 42plf5332d/37 backlight strobe

    Video here:
    https://www.youtube.com/watch?v=GVV4...ature=youtu.be

    If I leave the tv unplugged for weeks it might work properly for a couple of days, then the strobe returns. I didn't see any bulging caps or leakage on the power supply board. I should have taken some photos when I had it apart, but I'll go back and snap a few if I am able to get any replies here.

    With the limited info I have provided so far... is it sounding more like an inverter issue or a power supply problem?

      Hmm--Not heard of the model number--

      Are you sure its not 42PFL5532...?

      Pics of the Internal boards will help, I suspect its the PFL Plasma set--ie, no inverters...

          42pfl5332d/37

          My mistake, I typed the model number incorrectly. It's an lcd set. I'm going to try and take some pictures this afternoon.

                      I had a Phillips ambilight LCD do this after replacing the inverter slave/master inverter boards. I had brightness all the way up to solve it temporarily but I think it was something to do with with Eco setting active dimming backlight sensor that failed on the mainboard.

                          Philips TV Backlight Repair
                          by chestercc
                          So i'm trying to replace the LED's in a Philips TV. It's 42" with a 715g7262-p01-000-0010 backlight driver board based around an O2 Micro OZ9902CGN.

                          My issue is when I replace all the LED's on one board with the new 3V 300ma ones they immediately burn out when the set is powered again. I previously tried the same thing with 6V LED's and the backlight flickered for a bit but wouldn't start.

                          The original LED's which I removed which are still working start to melt and burn when given more than 3V on DCPS so I know they shouldn't be higher voltage ones.

                          ...

                          Trying to control Philips backlight manually with PWM — brightness increases with frequency...?
                          by ohren
                          I raised the question of whether PWM on the power board "dim" pin would be a reasonable assumption for controlling the backlight of a Philips TV (55put6101/12): https://www.badcaps.net/forum/troubl...d-tv-backlight. I didn't receive any insights there so I went ahead and tried it.

                          The setup is basically:

                          Rpi3 hardware PWM → 220 Ohm → NPN transistor → dim pin

                          Transistor is switching the 3.5 V supply on the power board....

                          UN65TU700DF picture and sound but no backlight. BL tests ok but repl. PSU didnt fix!

                          this tv is throwing me for a loop. do samsung tvs no longer have the backlight self test feature built into the power supply?
                          i tested the backlight with my LED tester and it lights up both strips. one of them reads 100v and the other reads 63.7v.
                          unplugged mainboard from power supply but left backlight plugged in, and then plugged psu wall power in. expected to see backlights light up but see nothing.
                          according to how ive diagnosed in the past, this would almost always be a bad power supply. replacement power supply was cheap like 20$ from ebay. but still i get not even...

                          Philips 55PUS6804/12 turn on & off (probably backlight issue)
                          by ovrax
                          Hello everyone,

                          First of all, please excuse me as I'm quite new to this field.

                          I have a Philips 55PUS6804/12 TV. It turns on and off instantly (backlight flash). I personally think it's a backlight issue (faulty LEDs). Could you help me confirm my diagnosis?

                          I've checked and the T-CON seems to be fine. I disconnected one ribbon cable at a time at the bottom, but the problem persists.
                          The Ambilight works perfectly and stays on.

                          No sounds.

                          Thanks in advance.

                          philips 55pft5500/12 Backlight issue. What am I doing wrong?
                          by DoOm86
                          TV philips 55'' no backlight (image ok).
                          I tested the backlight with my led tester from the unplugged connector cable and it lights up. I had voltages at the motherboard connector, but anyway I order a new psu. Same problem, same voltages. Disassembled the TV and checked every strip with my led tester, they all light up, same voltage for every pair of strip (they go two by two).
                          What am I missing?

                          And something else I don't understand. I checked and I have 3v Leds, 10 per strips. Why every pair of strip (so 20 Led) take about 32v when powered up with my led tester 🤔
