    PHILIPS 42PFL8684H/12 led blinks 2 times, dead IC

    Hi!

    I have problem with PHILIPS 42PFL8684H/12 tv. First it stoped working and red led started plinking two times over some time. When i opened tv then there was ic FDS6930B burned out, so i changed it with control ic NCP5422ADR2G for that ic. After change when i plugged my tv to wall, some electric sound started to come from power board. Something like wants to star up many tomes and then this ic burns out again, all the time in one place. i have done it 3 times now, no changes. Can it be that all SSB board is faulty and i need to change that? Cant find any more parts that is blown up or any way damaged.

      Get the chassis number and try find the service manual. They can be a great help with Philips.

          already tried with that, but no help. There is not much talked about power board, more about SSB. Or its to complicate for me to understand that manual there is lot of talked about how to test if that ic that i changed is faulty, but that i already know that it is. Now i jut need to know where can be the reason why it wont start. If tv is plugged in, and i disconnect one ribbon cable where 12v and other useful things go through and i put it back, for few seconds, backlight turns on and then shuts off again.
          Sound what that thing does and how it looks is here: http://www.youtube.com/watch?v=1IO4xJYJhfY

              XR-77A80K Dead set, red light blinks 8 times. Cannot find error code list.
              by mecha1166
              I have a XR-77A80K here. When plug in & press power, white lindicator light flashes on & off. about 30 seconds later, indicator light flashes 8x red. Checked Sony, Power reset = unplug & plug in. Factory reset involves turning it on, then pressing remote buttons when a picture shows. Well, neither of these "resets" are for a dead set like this. Anyone know what 8 blinks indicates, from the schematic? Thanks!

              HP Elitebook 845 G8 dead, only caps lock flashing 7 times. Charging light always on
              by esqmooo
              Hello everyone.

              This is my development machine. I've been using it since two years and half without any problem except sometimes it wouldn't wake up from sleep.
              Lately the issue became more frequent and powering it up would take few seconds to show the POST screen.
              Then the computer refuses to power on at all. Now only the caps lock button flashes 7 times then stops. The charging light is always on whenever a power source is connected (battery or charger).
              I tried long pressing on the power button, after several seconds it would go off then when the button is released...

              Samsung UE75TU7020k No picture, Standby blinks 2 times
              by brithepi2k
              My Samsung UE75TU7020k lights up fine when one of the ribbon cables are disconnected from the main board, lights stay on but not getting half a picture, I do the same with the other ribbon and put the other one in and lights stay on but not getting half a picture. The standby light flashes 2 times then reboots then it then tries to come back on again and just keeps looping until I take either one of the ribbon tables out (doesn’t matter which one I take out it stays lit when either one is out). I’ve tested the backlights but all working with none shorting out, I’ve replaced the main board...

              Samsung UN70NU6900FXZA - Red Light Blinks 2 Times Then Screen Flickers
              by Samunggg
              I've happened upon this TV, it came with no power cord or remote and it seems to be experiencing a common issue where the red indicator light blinks 2 times then the screen flickers as if it's trying to turn on. No picture, no sound. I suspect the functions of the TV are in good order and that the underlying issue is with the power button which is missing. It's just a white tab where the button should be which means I can't cycle it.

              I wanted to know if there is anything I can do or if I should just get a replacement module with the hopes it will fix the system. Alternatively if...
