    Alba LCD42880F - Panel Water Marks?

    Picked up this Alba set which has suddenly stopped working.
    On inspection the side button controls was disconnected from the main board and the Vestel power supply 17PW26-4 V1 displayed the classic bulged capacitors.

    Replaced all the caps and reconnected the side panel button connector and the set fires up OK.

    But if you look at the screen especially from an angle it looks like a water tide mark across the screen.

    Has anyone come experienced this before. The set has come from smokers and a fair amount of nicote stains the internal boards.

    I wonder if someone tried to wash down the set and water has got behind the lcd panel.

    I intend to open it up to clean the panel and see if that clears the problem but would be interested in knowing if anyone else has come across this.

      Thanks Vincerogers. I'm hoping that's all it is. The TV picture is reasonably good so would be worth my time cleaning it up.

        The diffusers might need a bath, Ive had this recently on a Ves315 panel water on the diffusers I just showered them down and wiped off set looks like new now image wise. Its called the Mura effect.

          as Reecey said: The panel needs to be taken apart and the diffuser mats cleaned.

            On opening I have never seen so much water holding the sheets together. They have all had a good clean and I'm just waiting for the top sheet to dry.
            Next it's onto giving the LCD panel a careful but thorough clean. The amount of food stuck to it. Arghhh.

              Might be best to actually bath it matey, as just drying one area from what I have found causes patches in areas.

                    Nice these 17PW26 sets are quite reliable after a recap

                      by sam_sam_sam
                      I got lucky that when I got home and was about to get some ice out of the ice dispenser I hear and see water running down the outside of the ice dispenser what the heck is going on here

                      At first I thought that the ice dispenser mold was cracked so I brought a new ice maker because this one has been in there for about 10 years now

                      Well I put the new one in and wait and I wait for the water valve to open and let water in no such luck well there is a way to check the function of the motor and the water valve on this ice maker just need a jumper wire β€œL” to...

                      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.
