    Pioneer PDP-434PU, no picture or sound

    Hi All

    This is a fourth gen Pioneer unit similar to the PDP504.

    I've downloaded the manual but I'm having a hard time deciphering the "code"

    When I press the power switch the red 'standyby' LED comes on then goes off then the green 'on' LED comes on then goes off then back to the red. It just keeps alternating between the two of them,

    How would you read that? Does the Standby red LED always come on first followed by the green blink code - meaning this is a "one blink Shutdown"?

    One blink shutdown seems to be related to "Communication failure of the panel-drive IC"

    When I measure voltages at the Digital Video Display board I get the 3.3VSB and nothing else.

    When I measure on the power supply I get 2.42 on AC Det and 3.3VSB

    Samsung TV model UE50TU: rebooting, backlight, sound, but no picture
    by TR103
    Hi, I have a Samsung UE50TU with:
    - sound and backlight, but no picture
    - when it arrived, it had a picture for a few seconds
    - it keeps rebooting
    - without ribbon cable between the two panel boards, it does not reboot but I have no picture
    - without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
    - when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.

    - without cable between mainboard and lcd panel and with a jumpered...

    Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
    by Mgiffune
    I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

    I ordered a supposedly ‘new' Tcon board this time, and

    Samsung UE60KU6079 backlight okay mainboard responsive, no picture, no sound
    by Ierwin
    Hello everyone,
    Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
    The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
    He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
    I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
    Anyway I still fully expect that there has been something seriously damaged...

    Samsung UN70NU6900F no picture and no sound
    by jchang
    Hi all

    I was just given a Samsung TV with the issue. I read various threads and videos and attempted the ribbon tape method to gain an image, but no luck.



    Symptom:
    No picture no sound.
    When I plug in the power cord, Backlight LED turns on for a half second and then turns off. The red LED next to the power button located center bottom flashes 2 or 3 times. When the power button is pressed after, it does the same thing.
    No sound at all.



    What I tried:
    1. I tried unplugging the left or right ribbon...
