      Are the inverters getting power and a control signal to tell them to power up?

              Look next to the connectors, most have names next to each wire so you know what they do. Most are self-explanatory. Post photos if you can.

                      What about on the inverters?

                          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.

                          ...

                          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....

                          Design of CCFL Backlight Inverters with Frame & Bar Cores

                          Summary

                          Portable devices, such as notebook computers and personal digital assistants are developed rapidly nowadays, which places an increasing demand on display technology. The LCD with cold cathode fluorescent back lighting satisfies the requirements on display performance, size and efficiency.

                          The backlight inverter plays a crucial role in supplying the power to the lamps of these flat-panel displays.

                          The frame and bar ferrite cores, described in this brochure, are especially designed...

                          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.
