    Thomson TV no backlight again

    Hi there,

    i received a TV in which the backlight did not work. After that I disabled the protection (pin 11 with 10k ohm to ground). The TV worked for 2 weeks, now it has the same error. I have redone the solder joints and replaced the 10k ohm resistor with another 10k ohm. unfortunately it does not work. Does anyone have any ideas? LED driver: OZ9976GN

          first time you ignored the protection. what will do protection if LEDs life ended !!!
          remove yours stupid Indian DIY and go straight to replace LED strips if the issue remain then yours IC worn out.

              When I turn it on, the backlight flashes. I don't have an LED tester, but I suspect the LEDs may last a few more weeks. I am planning to buy a new TV. It's not worth the hassle of repairing it.

                  Ok, why did you waste our time if you didn't plan on repairing it?

                      probably enough leds have burnt out that nothing short of replacement will work.

                          This fix is like disconnecting your check engine light in your car if it comes on. Problem solved!

                                  Thomson 50UD6306 (TCL) Backlight Issue, starts then stops, led changed
                                  by Cornito
                                  Hello Team,

                                  I'm back with another backlight issue that I thought was simple, but it turned out to be more complex than expected.

                                  Let me provide a brief history: The TV was working well, then one day, the backlight started and shut down. I thought I had an LED issue leading to this behavior, so I replaced the LEDs with brand new ones. However, the issue remains the same.

                                  Next, I replaced the electrolytic capacitors attached to the LED power supply, but the results were the same. I then replaced the driver, a OB3365RP, and did it twice due to the same result....

                                  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...

                                  Guide me through repairing a Dell p2210f LCD ccfl backlight monitor
                                  by DanPoka
                                  I bought this p2210f dell monitor to fix. Schematic is the same as p2210.
                                  Behaviour is that monitors comes on but then backlight switches off almost instantly. If I look with flashlight I can still find the "No signal message". So definitely a backlight issue. Trying to advance the issue I proved that the protection circuit is switching off the backlight by shorting out C3 and resistor to disable the INL chip then re enable by removing the short.
                                  This is where it gets interesting. When I disassembled the monitor to solder leads on c3 capacitor I noticed the backlight flickered...

                                  Hello all,

                                  Am trying to figure out this backlight issue with this A1990 Macbook Pro.

                                  Tests performed:

                                  There is no backlight even with a good screen.
                                  Backlight IC is receiving the correct support voltages.
                                  Fuse F8400 ok
                                  Current sense resistor R8400 ok
                                  Backlight IC is receiving 3.3V on enable pin.
                                  Backlight IC receiving voltage from PPBUS_G3H, aprox 12.5V.
                                  Backlight IC receiving 5V from PP5V_G3S
                                  Backlight IC BKLT_SCL and BKLT_SDA both measure 0.545V diode mode to ground
                                  I2C_BKLT_SCL and I2C_BKLT_SDA both measure...

                                  iPad Pro 12.9 5th Gen Backlight Issue
                                  by cheebster
                                  Hello, got an iPad Pro A2378 12.9 5th gen with no backlight. Got another test unit without screen, tested the screen, still no backlight with the test unit.
                                  Figured out the backlight on the screen was bad, ordred a new backlight from mobilesentrix, *carefully replaced it* without damaging the lcd, oh well.
                                  Final result, issue is still there, the screen has no back lights. So i'm back to square one, with 3 hours less and 100$ out, issue still on the screen.
                                  The panel is still ok, i can see the apple in the middle of the screen when it kicks in, just no backlight.
                                  Anyone...
