    Sanyo DP5834 - Gray Screen

    Hey All,

    I have a Sanyo DP5834 that did have an issue with the backlights, but I disassembled the unit and repaired the LED strips by resoldering all of the connectors. Now I've reassembled it and I have backlights and sound, but a grayish screen. I can tap on the screen and see that it's on, but no picture. All voltages seem to be correct on the power board.

    Based on the LCD Flat panel TV troubleshooting guide by Bud Martin, I'm thinking the T-Con has failed because I'm getting 12v both into and out of FP1 on the T-Con. Am I on the right track?

    Thanks,
    Todd

      Seems my guess was wrong. I picked up a T-Con since they're inexpensive, but same result. Guess I'll start over with checking test points again.

          Sharp TFT-LCD Model No. LQ050Q5DR01 gray screen

          I have a older eddy current tester made by Olympus that uses interchangeable TFT-LCD screens. I have two devices that each take the same removable screens. One is an Olympus NORTEC 200D+ and the other is an Olympus SONIC 1200M EMI. I have searched the internet high and low for service manuals for these units with no luck. Both these units were used extensively by the US military for NDT on airplanes. The detachable screen plugs into the base unit via a weird non standard VGA connector. Buttons on the removable display are used to power the units on. When the power button is pressed the unit makes...

          Sony 8K XBR-75Z8H White Screen Vertical Bars Tcon Code. Help Needed🙏
          by Daren87
          Hello everyone,

          I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the...

          Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
          by Ryan.man
          Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

          My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

          This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

          Lg TCon test pins for screen test
          by alltvrepairs
          Hi,
          i have a 65 Panasonic TX-65HX710E using vestel 17MB170 main and Lg tcon.

          Few drops of water fell probably near COF and have no display. Tried removing tabs but no.part of display present as if tcon fuse open. However 12v is present and tcon can be felt warm enough that supplies are present. Backlight and sound ok.

          Anyone knows if this TCon 6870c-0805A has any special test pins for rgb test?

          Appreciate your help....

          I have a Panasonic TX-48CX350B tv , it powers up ok but the screen is blank, the backlights are working, there’s nothing else though, no picture or sound.
