      I'm confused. You are saying unit doesnt power up and you are still looking for +1.35V rail?? This rail will come up after poweron only.

          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...

          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 50AU7172, only blinking red light
          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.


          Regards, Norbert!...
