    Crud between layers in LCD panel

    Hi, all.

    Just repaired my Acer Ferrari F20 monitor (bad caps on inverter card) thanks in part to info gleaned from this site, so TYVM for that. :thumbup:

    But, during the repair process, a couple of tiny pieces of crud (just big enough to be irritating) have somehow made their way down in between the layers in the panel itself. It is not a case of bad pixels (looking from different angles, you can see that the crud is actually in front of the backlight, but behind the LCD layer, and different pixels are affected by angle of view) (sorry for the emphasis, but getting tired of being dismissed by people saying "oh, it's bad pixels, nothing you can do" when it's obviously NOT :grrr: ).

    Now the question: how difficult/dangerous would it be to take the panel itself apart to get rid of them (and some dust in the same interstice that's been there since I bought it)? I was happy to deal with the previous issue without delving further in to the guts, but the monitor is almost too irritating to use now.

    Thanks in advance for answers/advice.

    it's doable,
    but you will probbly make it worse.
    the plastic layers build up static and you get loads of dust pulled in!

      I think it is very doable as long as your not throwing them on a carpet or something!

      I have personally took apart many many many more that I can count because I needed to get to the CCFL's and when i put them together I turn on a white background and look for specs. A few times there was dust so I took it apart again and cleaned it out.

      Although it is all about the level of confidence you have with this sort of thing. There is lots of crap that people are doing that I would never dare to try to do haha.

        Wouldn't a wrist strap deal with that?

        Anyways, thanks for the answers, but I've kind of solved the problem (well, got the amount of crap in there down to a level I can [s]tolerate[/s] stop being tempted to possibly make it worse) by an embarrassingly low-tech method:

        I tapped on the glass (using knuckle and fingernail) hard enough that they fell down out of view.

        So if you guys want to file that into the old bag o' tricks...

            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....

            QN55Q60R Service Menu Panel Help
            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.

            Samsung UN50TU8000 - Dead Panel Forensic Questions
            by KYBOSH
            I came across a 50inch TU8000 that wouldnt start up properly (blinking stand-by light, backlights would cycle on and off).





            When i opened it up and removed the power to the mainboard the backlights powered up and everything looked uniform.
            When reconnected the mainboard but disconnected the flex cable to the panel i heard the TV startup with the intro sound.






            Later I checked for shorts on the panel PCB boards but could not find anything.
            When I took a look with the FLIR i noticed the 2 resistors...
