    Unknown transformer : how to find a good replacement part ?
    by the_rem
    Hello guys,

    I would like a quite old but still good 800 W ATX PSU to be repaired. The problem was an extremely heavy coil whine coming from the small secondary transfomer on the PCB.

    I desoldered it hoping the references on the upper side would allow me to find a adequate replacement part. Sadly the written references drove me nowhere but to the manufacturer (I-MAG). I sent them a message like a bottle in the see asking them to send me a datasheet of the transformer. And... They responded ! I received a kind of datasheet (see attachment) but my competencies do not allow...

    IR night vision goggles to find shorted panel line?
    by Lee M.
    Has anybody tried to use IR night vision goggles or other thermal imaging device to find a shorted line in a ribbon cable going from a panel driver board into the panel? I would think the shorted line would get hotter than the other lines and might just show up on a thermal imaging device. Just wondering if anyone has tried this and if so did it work?

    LG 49UJ6500 LCD panel lighter band that goes away
    by howardc64
    49UJ6500 LCD panel has a lighter band on top when first powered on. Goes away (or gets much fainter) after TV on for a few min. After powered off for awhile and power back on, same band appears. If powered on immediately after powering off, no or much fainter band. Running the latest firmware.

    Disassembled the TV and lifted the LCD panel during testing. Band is on the LCD panel (can see the band on the panel as I lift it slightly) Backlight is perfectly even at the top edge. Double checked LCD panel alignment in the frame and is perfect but since band moved with the panel, its on...

    SAMSUNG UN50TU8000F rebooting, backlight ok. No 12v to panel boards.
    by triplefour
    TV flashes backlight then reboots over and over. no image. Client said it used to have image for a bit before rebooting. Got worse over time.

    tcon is built into mainboard.
    Only one cable goes to panel boards.
    there is a cable from one panel board to the other that links them.
    cost cutting measure that results in us having harder time to diagnose.
    removing the link to the second panel board allows TV to stay on with stable backlight but no image.
    used cut off tape method to mask 1 maybe 2 pins on the side of the cable that goes to that second panel board....

    Samsung UN65TU8000 - Panel Issue [ hole in ribbon cable ]
    by NWArkGuy
    Well, I will be the first to admit that I screwed up...

    In attempting to replace the backlight in a UN65TU8000, I made a hole through one of the ribbon cables between the board that runs along the bottom of the back of the TV and the panel. This lead to a between a 1/4 to 1/2 inch vertical stripe running the full height of the image.

    I don't have the experience; personally, to solder a bridging wire for the paths that were cut. So, I have been on the hunt for other Samsung TV's of similar size.

    I have 2 that I have found and have in my possession. ...
