                I can't help with your laptop problem, but some advice: you don't need to write everyting in capitals, unless you are trying to give us all a headache.

                  i check the voltage and found

                  1. pin no 6 of PU121 having no voltage at all check 2.2E fuseable resistance and its ok,
                  2.+3VALW is showing short

                  *PQ16 drain also showing shorting remove PQ16 even then shorting

                  PU121 all pin pin no voltage all 0v






                  Agent24 sorry for everyting in capitals i will take care in next time thanks for responce

                            Had one of those shorted on DCBATOUT too, ended up being a ceramic capacitor. Found it using a large 3.7v lithium battery and feeling around for anything hot.

                                      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.

                                      Hey guys great forum glad to have found it. I bought a Sony XBR 65X900C cheaply because it didn't work. No signs of life at all not even a light/led. All I hear is a brief high voltage sound when I throw the power to it.

                                      Didn't see any obvious signs of damage so right away started checking voltages. This is what I see:

                                      Hi guys!

                                      I'm trying to repair a TV that a friend gave me recently. Lightning struck next to his house and broke the TV apart from more electronic devices.

                                      First of all I've checked the power supply and it works as expected. I removed the logic board and shorted the 3.3v standby output to TCON_ON and POWER_ON and every voltage was generated as expected (12v and 25v for logic board and 32v for TCON).

                                      When trying to boot the TV normally (having the board connected), the TCON_ON signal is not generated from it which made me think there's some issue in the logic...

                                      I'm working on my Samsung QE65Q9FN (65" Q9FN QLED, European model) with relay clicking and no picture. The power supply board in the display itself is the BN44-00944A, known on the board itself as the 65A board (silk-screened designation). There is also a second board, the 65B, which looks identical but is only partly populated for the LED power.

                                      Symptom: Continuous relay clicking on the one connect — TV will not start up, no picture. However the standby LED is on constantly — so the standby supply rail appears to be alive and the...
