    Broken Samsung 2253LW

    Hello I got a Samsung 2253LW for free a while back and the backlights don't work. The monitor had bad caps so I recapped and when I turned it on there were lines on the screen then it went out. The ccfl's dont work on a good board but the board wont work on good ccfl's. When I plug the ccfl's into a good board it flickers and makes bad noises then goes out. When I plug good ccfl's into the board it flashes then goes out. Is there any way I can test the inverter transformers with a digital multimeter?

    What could the problem here be?

      are you testing the ccfls in the same model board?, i had one of these and changes the ccfls for led lighting (one of the tubes was fractured at the end cap, i also disabled the power to the inverter board as the brightness control was done by the seperate power board.

          No the board is a different model. Does this matter? I have ccfl's that will work in other boards.

                  Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                  by Tynan Dill
                  I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                  Upon bringing it home and plugging it up, it showed a standby light.

                  I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                  The screen seems to blackout and stay black, but with a flashlight I can see the display.

                  With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                  Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
                  Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

                  Samsung Power Supply Board BN44-00874F
                  by Nicktronic
                  Hey everyone,

                  This power supply board is hard to find but there are repair kits available. This board had a blown fuse, FP801S, blown PFC MOSFET, QP802CS and ceramic cap, CP809. I replaced them with parts I already had and tested the rest of the parts that would've come in the repair kit and they were fine. I powered the board up on the bench expecting, in typical Samsung power supply board fashion, to see all my output voltages but, nothing. 0 volts on CNL801, CNM801 and CNT801. The only thing I have is 170vdc on the filter caps. No standby voltage either.

                  Anybody...
