    Samsung un82ru88000f - Boot loop sort of but can correct with taping of LVDS ribbon
    by NolesFan
    Hello all... TV started boot looping. Opened the back panel and tried to isolate the problem. Just PSB no boot loop. PSB and MB no boot loop. Plug in the LVDS from panel to MB and boot looping starts up. It doesnt matter of order that I plug the LVDS ribbons back in, only 1 and no boot loop but as soon as 2nd one plugs in boot looping. I then noticed a flicker on the screen when I was closing the clip on the harness to the LVDS. Shut the lights off so I can see better, and I noticed as i slowly close it, I will get a picture, but as soon as it clips in, I lose picture and booting happens. So I...

    Need help with HP15-fxxxxx Quanta U99/U92 LVDS <> eDP conversion.
    by lpraderi
    Hello , for some time I was studying Quanta U9x/8x schematics and the option to use both type of screen (LVDS 40 pin / eDP 30 pin).
    In some cases to use LVDS screen PCB use converter IC RTD2132/6
    Now I found an HP 15 F series U99 mainboard with RTD chip not populated and LVDS 40 pin lcd touch screen
    at the same time I have another HP 15 N series with Quanta U92 mainboard and RTD2136 with eDP 30 pin lcd screen (no touch).
    Maybe someone more experienced in the subject can clarify if is posible to change type of screen used with some resistors / bios options change.

    by TCCTech
    Hi all, I appreciate any help at all on this I have an HP Elitebook 840 a customer spilled tea on it and it shorted/melted the LVDS port I found the schematic here

    file:///E:/Users/BBB/Downloads/HP%20EliteBook%20840%20-%20ZBOOK%2014%206050A2559101-MB-AX1%20COMET%20DIS%20SI2%20Schematics.pdf

    UN70NU6900FXZA Won't Boot Unless I Temporarily Disconnect Right LVDS Ribbon
    by Scincidae
    I recently was given a UN70NU6900FXZA that would only boot loop once plugged in (auto powers on when plugged in). I found that disconnecting the lower (right side) LVDS ribbon, then plugging the TV in, followed by reconnecting the lower LVDS ribbon will allow the TV to work 100% normal as far as I can tell (no lines, no discoloration, no dimming or anything like that).

    I tried the tape method on the lower LVDS ribbon and found that if I cover pins 10 and 11 (counting from the bottom up) allows the TV to boot normal but 25% screen all the way to the right side is discolored. While...
