    Samsung 192V goes black in 1-2 seconds

    OK, another problematic monitor needs fixing. It shows a perfect picture for a second or two then goes black. The picture can still be seen with a flashlight. I replaced three 1000uF 10V caps as well as two 470uF 25V but the problem is still there. The original caps looked fine but I decided to gamble.

    The power board is FSP048-3PI01 BN44-00082A.

    So what else can I try?

    Cheers

          Maybe there's a bad CCFL.

              Bad inverter transformer? Bad Inverter circuits? Bad lamps?
              If you have two test lamps then it will save times trying to figure out if it is the board or lamps problems.

                  Samsung UN40H5003 boot loop every ~8 seconds
                  by eigma
                  Hi, I rescued a Samsung UN40H5003AF (H = 2014 FHD) from the curb. Symptoms are: standby (red) light comes on, stays on for 8 seconds, flickers off, then comes back on, and the cycle continues.

                  Service manual: https://www.electronica-pt.com/esque...is-u8la-71272/

                  SMPS board: checked voltages, all seem normal (A13V = 12.8V, UD = 3.3V, PWM_BLU = 0.77V, PS_OnOff = 5.5V). Remove 10p cable to main board -> backlight comes on. I think this means SMPS board and backlight are good.

                  Main board: BN94-07592P / BN97-08922R...

                  Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
                  by Mgiffune
                  I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

                  I ordered a supposedly ‘new' Tcon board this time, and                  ...
