    scratches in lcd led panel

    I just fixed a tv last night for resale and didn't realize till it fired up, there was some scratching on the panel. I tried scrubbing with glass cleaner and tissue, but still some there. Anyone know a sure fire trick to fix it?

    Re: scratches in lcd led panel

    If the scratches are not too deep, I have had success with the plastic headlight polishing liquids sold at most car shops. The hassle you face with scratch removal, is if do you polish it out, you risk creating a shinny spot on the matte front finish.

    http://www.popularmechanics.com/cars...a2648/4252611/

    Lots of sites talk about scratch removal, but what they are really doing is filling in the scratch void with things like chapstick wax, vaseline and even olive oil. White pencil rubbers don't remove the scratch, but tone down the sharp edges on the scratch.

    The questions you should be asking first are, is the scratch affecting it while it runs or is it purely an aesthetic fix when the tv is off? If its affecting it while on, then it's usually a very deep scratch, white rubber may tone down the light transmission caught on the edges. If it's purely an aesthetic fix, consider getting a piece of thin clear plastic and put it in the frame between the bezel and the panel face, just be careful of any air gaps causing rainbow-colored interference patterns.

    Rubbing alcohol (isopropyl) can also be used as it softens the plastic an allows some of it to flow slightly, but you'd want to really practice that carefully on screens you don't want.

    I haven't used them (hard to get here), but you can also try dedicated products like Novus 7100.

    But again, it's polishing the surface. Good bye matte finish.

    Alternatively, a large version of this type of screen protector is available, but at a price

      Try a clean pencil eraser. You might be surprised. I've personally used it to mask some really deep scratches. If they're light enough, you won't see them at all.

        you can buy NOVUS products from arcade suppliers - they are used on pinball machines.

        btw, this is why i think all lcd's should have a glass front!

            There is a Youtube video, with a Dell monitor, where that person removes a layer and then it becomes even better the image.
            Do not do that. I have done it with a scratched monitor and I have ruined the monitor.

              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....

              by Storyteller12
              I had a the above tv qn55q60r that had a bad panel but everything else good. I had another panel here from un55nu6900 with bad leds and melted diffusers.

              I put the nu6900 panel in and powered it up and it does work but there are lines vertical lines.

              I was trying to change the panel type in the service menu but don’t see my exact panel. Anyway to fix this or someone have similar experience.

              the clear picture is the panel type from the service menus on the nu6900. The other 1 is the panel type that was set for the q60r with the bad panel....

              Missing LCD Panel Voltages VGH, VGL, VCOM (TCL 55P6US Sound & Backlight but NO Picture)
              by maneatingmonkey
              I have a TCL 55P6US with sound and backlight but no picture. This model does not have a T-CON board, and the right (rear perspective) panel board is fed from the left panel board. I have not been able to induce any change by disconnecting the secondary panel board or the tape cut-off method on the primary board.

              There are a bunch of voltages missing on the panel boards. I can't find any shorted caps of the panel boards, and all of the missing voltage rails read in the kiloohms, which leads me to suspect the issue may lie on the circuit board, rather than a short in the panel.
