    LG 65LW6500

    Hello all

    thought I would start a thread on this model

    connected to power
    cannot see a standby light
    when i press the power button on the TV a standby light does appear and it is white
    there is no picture and no sound
    i looked for picture with a torch and could not see one
    i pressed the power button again and the standby light went out

    shall start to remove rear cover and look what i can see

    thank you

    Here are some photos
    I cannot see anything visually at the moment
    Tried to disconnect the mainboard but TV just turned off
    I had hoped the backlights might come on
    Anyway I am going to focus on the LEDs

          The main problem with this LW series, this chassis (LD12C) is the failure of the main processor, a reball is needed, for diagnostics, blow a hair dryer without fanaticism on the processor and the TV should start.

            Samsung TV`s UE32J5500AK and UE48H6400AK Red Standby Light - No Picture/Sound
            by slimsoul
            Hi, I'm new here and looking for some advice on how to diagnose an issue i have with 2 samsung TVs.

            I have a UE32J5500AK and a UE48H6400AK both with the same issue of red light but nothing happening on the screen, the red light responds to remote or button press by flashing once but stays red. I have searched forums but most turn up a blinking red light.

            I have tried replaceing the power board on the UE32J5500AK last year but this resulted in the same outcome.
            The UE48H6400AK recently developed some small bright areas on the screen, then last week would not power...

            LG 55EG910V - no power and no standby light
            by AleMonti
            Hi everyone,
            I'm trying to troubleshoot and repair this old LG OLED curved TV, model 55EG910V.
            I did some basic troubleshooting and reviewed most related posts here, but I wasn't able to isolate the issue.

            The TV shut itself off during playback and never came back to life - the standby light remains off. My dad claims that it has happened a few times in the past but the issue resolved itself after some time. Not this one.

            After checking the basics I did the following:
            • I measured all voltages and as expected the only active supply is the 3.5V standby. It

            vostro comes up with back light but no picture
            by koby058
            Hi people!!
            The owner said it showed bad picture once in a while (attached)
            I see that there is back light but no picture.
            I want to ask if it is possible to disable the NVIDIA GPU and use the intel one?

            Also attached schematic and BDV

            Philips 37HFL5682L/F7 no standby light, incomplete service manual?
            by jasonbay13
            picked up a tv and when the power is plugged, the standby light flashes real quick then goes off. of 3.3, 12, 24v is all there but i couldnt find any 5v on the back-end board. ON/OFF is low, which it seems is what turns on the backlight so i removed the wire at the back-end board and put a 10k resistor to the 3.3v, which when plugged in brings on the backlight for a split second and also a blue light "LED1" on the inverter board, which goes off after a short time.
            am i missing something to bring on the backlight or is the inverter/ccfl gone bad? would that cause the inverter board...
