    Telefunken te43550b40q2k intermittent backlight

    Good morning everyone

    I have this Telefunken te43550b40q2k TV that has intermittent backlighting, sometimes it turns on and then does not turn back on.

    I tested the LED bars and all three work, not even one burned LED, then I tried to put only two bars short-circuiting the end of the connection cable and it does not give any problem the LEDs stay on without problems, I also tried short-circuiting the central connector and the initial one, always no problem, but as soon as I put the third bar, no matter the position the problems start again.

    Thanks in advance to everyone.​

      Samsung LN46C630K1F – Intermittent Backlight, BN44-00341B Power Board

      Summary for TL-DR readers:
      • Backlight is intermittent, may come on with TV boot or not. No flickering, never fails during TV on.
      • Have obtained Samsung schematic & service documents - Can upload if helpful.
      • Have read ALL applicable threads
      • C1818 and CP820 replaced as low hanging fruit
      • CN802 data taken for normal and failed BL operation. SUMMARY: Pin 2 - 5vDet = 3.52 @normal, 0.0 @BL fail. Pin 6 - EPWM = 1.631 @normal, 1.058 @BL fail.

      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...

      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...

      No Backlight Macbook A1990 820-01041
      by Comp_Pro
      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...
