    Toshiba 37av505d no backlight? Fixed

    Well it was a pleasure not seeing this... not a crappy vestel board in sight even though its an old model (2008)
    it turned on and got sound but no backlight
    opened her up no badcaps and the fuse was dead on the inverter MPF3003 so hunted around and the big power transistor at the top had gone short on the solder side just above transistor theres a 4r7 resistor which was hanging on for dear life checked and resoldered her in, i didnt have any toshiba K4107 so looked up spec and replaced it with a 20n60 all fitted and testing.... cleaned out 8 years of brown smoke dust ewww but brushed up nicely fully working now

      Good work mate, think its a murata Psu (normally start with MPF) seems ok for a 37" not the best but hopefully lasts alot longer

              Samsung UN55NU7300F Curved TV. Half side backlight out. Fixed by just removing the rear snap cover
              by howardc64
              TV was fixed just after removing Samsung's rear snap cover.

              This curved TV's construction is rather interesting. When the snapped on back is removed, rest of the TV will relax the curvature. Top of LCD panel is loose as it wants to straighten out against the slightly curved bezel. Snapped back provide most of the curvature shape. So just simple disassembly of rear cover will allow the rest of the TV frame to relax its curvature. Thats probably what fixed it but no idea which connection. 4x LEDs are edge lit.

              Maybe PSU->backlight connector didn't have a good contact?...

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