    sharp LC-60LE650U panel or gate drivers?

    Hello again,
    So I've read up on these sharps with their gate drivers being shorted.
    Solution,rip them off the panel on the bad side.
    Ok,I think that's what I have to do to this one,but I like to double check with you guy's as pic#1 shows something weird.

    I got this tv with only halve screen working,other halve white. They had disconnected the one ribbon from t-con.
    You can see in pic#2 that towards the white,the screen is getting darker,making me suspect the gate drivers. The noise on the side of the screen that's working(snow) refreshes quick.
    When I plug in that right side ribbon at T-con,I get pic#1,it then shows snow on both sides that refreshes super slow,while still showing that black bar as seen in pic#1

    Could use a second opinion on this,rip out the gate drivers on the right side or you guy's got another suggestion?

      I was hoping you would say the y-main needed work.

      I am going to rip the gate drivers off on the bad side,nothing to lose I'd say. Will first check if perhaps in a stroke of luck there is a shorted cap on the small board right at the panel.
      Will report back later today what the outcome is.

          So got around to tear the gate drivers off the panel.Super easy to get too.
          Now I believe it would have fixed it,as the snow is responsive now and it brings up menu and what not easy and smooth. But the colored vertical lines are still there,I'm guessing they fucked around with it and wrecked that part of the screen.grrrr...
          Parting it out,unless DIAH has a smartass solution?

              Sharp LC-55LE643U, bad gate drivers?
              by wagivem657
              Just received a busted Sharp 55" Aquos (LC-55LE643U) from a coworker. He tried swapping all three boards (power, main, TCON) to fix the problem, but it had the same issue. He was kind enough to give me the TV and both sets of boards for free, so I can try to get it working for myself.

              Unfortunately, I think I may have made the problem (much) worse, but I'm interested to see if the original problem was fixable at all regardless...

              Pictures show the issues:
              1. shows what happens when you first turn the TV on. Well, kinda, the white column wasn't there at

              Panasonic TX-48CX400B 50" (Vestel) - Damaged COF's? Repair Possible?
              by Russ17
              Hi All,

              I was gifted a 50" Panasonic (Vestel Version) LCD, which the previous owner had disassembled and gave to me completely in parts, which had some failed backlight LED's.
              I replaced the LED's and got it working, but found some issues with the picture which I have never experienced before.

              Having looked on YouTube and various forums, it seems that one of the COF gate drivers has failed.
              None appear overheated or physically damaged, but if the gate drivers on the left side of the panel are touched with a bare hand while the set is on, the picture...

              Asus X532FL 3.2V at source and gate
              by Lvsitano
              I am having some trouble with troubleshooting a Asus X532FL rev 2.0 motherboard, which does not power on. So at the first MOSFET, I am getting 19V at the drain, and then 3.2V on both gate and source (compared with ground). Of course, the 2nd MOSFET's source will have 3.2v at source.

              First MOSFET is a QM3056M6 and 2nd MOSFET is a QM0930M3

              I already checked first MOSFET and source and gate are not shorted (drain with source not shorted either). Also I have 1.7V at the LDO rail (measured at the keyboard connector, as the power button is on the keyboard).

              First...

              DRIVER_PNP_WATCHDOG error re. old drivers in Windows 11 install image
              by japlytic
              In a Beelink GTR mini PC, mine has an Intel AX200NGW WLAN module.

              Tried (only with keyboard/mouse connected):
              • BIOS + database update
              • Using latest Windows 11 image built with official image creation tool
              • Previous setup version for Windows 11 installer
              • Replacing SSD without a slow block (the previous SSD had a slow block with access time > 500 mS)
              • TPM reset (worked to the point where DRIVER_PNP_WATCHDOG error message is displayed briefly after the point of stalling)
              • Disabling power to WLAN and LAN modules in BIOS (Advanced > AMD PBS > PCI Express Configuration)

              LC6685 based LED drivers
              by pavithra
              I have 50 Chinese constant current isolated LED drivers based on LC6685 IC. 35 drivers are working fine, but there is a slight flickering in the rest of the drivers.
              I have checked the output with oscilloscope and found that there is a slight random voltage fluctuation.
              Is it possible to get the datasheet of LC6685 IC?
              Also highly appreciate if you could let me know what could go wrong....
