    Sony kdl-42es441 Dead no standby light

    Hi
    This tv is dead but i am getting the 3.3v stand by and 3v for the power on on the power supply.I currently suspect IC6501 on the power supply but there are no markings on it. The power supply is a APS-334 and I would like to know that ic part number. Thanks.

      Sometimes the markings for SMD ICs are below. Why do you suspect this IC. Did you try a self test to turn on the PSU?

          I don't know how to self test the PSU. How do you do that?

              Can we see the pictures of the whole backside of the TV showing all the boards?

                  QN750Q8FNBFXZA Service Error Codes Needed - Error code 1-3-1-2 ? Dead set, only blinking standby light in repeating sequence
                  by mecha1166
                  I am working on a QN750Q8FNBFXZA. Dead except the standby light. It blinks what appears to be 1 3 1 2. 1 long blink, pause, 3 short, pause, 1 long, pause, 2 short, pause, repeat. A service manual would be very helpful, or if anyone knows these error codes. 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...

                  LG 65UB930T - Standby Light can trigger but TV dead
                  by wushumike
                  The problem: When remote controller is press, the TV seems to wake from standby light goes off; but there is no backlight, image and sound. The relay did click on.

                  I have removed the power board to check. Using 2 x 10K resistor from 3.5V to PWR_ON AND DRV_ON, all the voltages is correct.

                  The main board has a red LED and is lited, but the optic link does not light up.

                  The Power board after sometime will start to blink x 5 interval.... I would assume this is to indicate DRV_On not working.

                  Any expert here came across the same problem? I...

                  TX-P50UT30B Dead - No Standby light.
                  by shagster
                  Hi, haven't been on the forum for a while. But I thought I'd ask here incase this has already been solved.

                  Anyway, I have this Panasonic TX-P50UT30B. It's completely dead, no red standby light, nothing. I took off the back and had a look at the fuses. All of them are intact. No shorts when testing the mosfets of the Power supply either.
                  And the capacitors look fine also.

                  I'm guessing it's a main board issue. But I don't really know tbh. Maybe a corrupt firmware flash, dunno.

                  LED TV Samsung The Frame 55 inch QE55LS03RAU Standby Light only
                  by ChristianBr01
                  Hello everyone,
                  I got a Samsung The Frame 55 inch TV for free from uncle cause it is not turning on anymore. I am in the second year of training as an electrician so I have knowledge already but I am far away from to be a pro.
                  The TV has Standby but ist not turning on. A Friend of mine owns a 50 inch Frame TV so I checked the One Connect Box and the One Connect Cable there. Both are good and working normally. I have opened the TV case and measured some voltages on the Board.
                  What I already found is that the 12.8V are not an the connector to the main board connector to the power...
