    Sharp 65le643u no video

    I have a sharp LC 65LE643u that i am trying to repair.
    I got the tv. with no video ,no audio and the screen slowly get bright white from center to edge.Voltage for m.b. (19v) is 19.46v and m.b provide the 12v for t-con also.
    Based on no video/sound i order a (used) replacement board .
    Replaced the main board, tv. start and i can see on screen no signal .I turn around to plug a hdmi cord and when i turn back to screen i see the screen getting white . With this board i have sound . Just to be sure i order a t-con board that make no difference.I am not sure if the main board fail . or is something else there. Any suggestion how to pinpoint the problem?

              by m1ch43lzm
              Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
              Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

              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....

              LG 55EC930V OLED - swich on swich of no screen
              by maxim2511
              My Oled Tv is 55inch tv, 3 days ago I notice that middle of the screen is getting warmer and on picture I have ghosting, missing red color. Color red was still displaying, but it was not so strong as corners of the screen and watching some movies makes me angry.
              Then I get an idea to take it apart and clean boards from dust.
              In side of Tv was not so bad, I take compressed air in can, and gently blow up.

              Also I was thinking to styrofoam sponge to isolate power board from screen that the middle of the screen will not worm so much. Because Led on screen when gets higher...

              LG OLED77G1PUA - No Video / Audio after a TCON Board change and Software Update
              by Hakuu
              Hi There,

              This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.

              After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

              More Details
