    le40b530w colour problem and double letters

    hi to all on the above model i have solarized picture and double letters

    i think as about as the double letters maby the problem is the same display
    but as about as the colours it likes as solarized picture
    i look to find the schematic for the above tcon card without success
    has anybody measure the voltages from the above tcon card to advice me how can i measure the gamma voltages ?

              samsung un43nu7100 BN94-13191C/BN41-02635A boot loop problem even with tcon jumper

              Hi I need help with a Samsung un43nu7100 BN94-13191C/BN41-02635A with boot loop problem even with tcon jumper.
              I've already try tape method and same happen, if I disconnect both flex from mainboard to panel tv boots normal even I hear Samsung sound.
              When I solder jumper to make t-con work with or without panel or panel cables connected it still reboot or power cycling.
              What I noticed is that there's no voltage in VHG, HAVDD, PANEL_3.3V, AVDD_17V or 12v near dc-dc chip.
              I check capacitors and diodes and didn't find any short IN MAINBOARD.
              Measured all power supply...

              Problem with LG Plasma 60PM6700 - Random power downs
              by theone111
              I have an LG Plasma TV 60PM6700 for the past ~12 years.

              In the last ~3-4 months I have been having some issues.
              1. Problem: It started with random picture disappearing (sound still worked).
                Frequency: Happened about once a week.
                Solution: Had to turn off TV wait a few seconds before turning it on again.
              2. Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
                Frequency: Happened about once a week.
                Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve.
              3. Problem: TV shuts down

              TCL 50S535 bad tcon or panel issue?
              by x_orange90_x
              Just bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side...

              Driving a Sharp TCON/panel with a universal main board
              by advant
              This thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.

              I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match...

              Problem

              This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....
