    Samsung PN51D530A3F – blinking red light & clicking.

    I am working on this plasma tv and have diagnosed it to defective X-main board.
    Q4202; Q4503; Q4101; Q4104 – SF10A400H are shorted
    Q4302; Q4301 – RJP30H1 are shorted.
    I cannot cross the driver ics – U4301; U4412; U4201. If someone chime their opinion or direct me to service manual, it would help a lot.

      If you did your work and diagnostic was the x-main just replace it try not todo things out of the ordinary you might be burning the power or y-sus board.

          If its a common fault, replacing a board will not ensure longevity. So I prefer fixing things to component level and use higher spec parts than the original.

              Samsung UE50MU6172 - red light blinking
              by matty24
              Hello. I have problem with Samsung UE50MU6172.
              TV won't turn on, red standby light is blinking.
              Power supply BN44-00807A is fine. I replaced it with the new one.​
              Main board BN41-02568B (BN94-12530E)

              I've read a dump (W25Q40CL). Can someone check it od fix it for me?...

              Samsung UE40F5300AK blinking red light
              by Fergal22
              Hi,
              I have the above tv that just shows a red light blinking twice 5 times, i have taken the back off and all the capacitors seem ok,
              When i disconnect the mainboard from the PSU all the led's light up blinking fast but as soon as i reconnect the mainboard back to the power supply i get the red light blinking again twice 5 times,
              I have attached pictures of the Mainboard, PSU and a small video (zipped) showing what happens when i disconnect the lead from the psu
              Any help would be appreciated...

              by norbiszoke
              Hello,

              We have this set here in our shop that is not ginving sign of life besides red light that is blinking one time after pressing the button and nothing more... After detaching the mainboard from the PSU (this set has separate board thank god?! or not...) the backlight comes on. After reattaching nothing besides red light.... Can anyone from the forum help me here? Thank you in advance. Here's a link with images of the mainboard and the memory IC's that are on it.

              Samsung UE46D6100 LED TV blinking red light indicator
              by 3DDD
              Hello, I have a Samsung UE46D6100. It cannot be turned on, only the red status LED flashes, the power supply part bn44-00458a gives an output of 5V(A), it is probably functional. I don't know where to look for the error, according to the video it should be a faulty mosfet. I found a mosfet marked WAAH, I don't know what it is. Can anyone help me?...
