    Can I test video output on different tcon/panel?

    Hi guys,

    I've come across the same situation a few times.. Where the TV powers up but the display is not right.. PSU is good, and I need to work out if the signal from the main board is bad or if the issue lies further down the line in the tcon / drivers / panel. Would it be possible to plug the LVDS cable in to another panel of similar size? Or are all the LVDS outputs wired differently?

    For example, I currently have a Philips Flat 14inch Flat TV. I have a 17 inch monitor screen that accepts the same LVDS cable. If I was throwing caution out the window and just plugged it in to this screen what is likely to happen?

    (I know we're normally meant to post exact model/makes etc but I'm looking for general troubleshooting tips, not a solution for this particular problem)

    thanks,

    Just an additional note: I am talking about video only. The idea would to be to illuminate the screen with a torch to see the on screen image, not to connect to the TV's lighting source.

      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....

      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...

      un60j620dafxza - Samsung No Display Problem
      by stylishconsultant
      Hi All,

      Need help.

      I have a samsung un60j620dafxza led tv. When I plug it in it has no display, no sounds, and no standby lights.

      So I opened the tv and disconnected the power to the mainboard and the backlight powered up. This according to many people says that this is a mainboard
      problem. I checked the voltage coming from the stb and I read 1.3 volts on pins 1,3,5 and 7 which are low volts instead of 13 volts which i think the lcd panel
      might be drawing too much power from the power supply that it prevents the right voltage going to the mainboard....

      General Questions on the Relationship Between Mainboard, TCON and Panel
      by mmartell
      My goal here is to be able to use boards on hand to swap into faulty sets when the faulty board is not obvious.

      I will start by asking what is the format of the output from the mainboard and is it generic in any way or does it vary by manufacturer and/or model ?

      And as far as I know a tcon and panel must be a matching pair because the timing of the signals and the voltages required to drive the panel are specific to the panel itself. (That may be a blanket statement that isn't true in some cases where the panel creates its own sub-voltages on its panel boards?)...

      Amazon Fire TV Omni K24NE5 tcon or panel bad?
      by Lee M.
      TV came on with BL on but blank screen. Disconnected one of the ribbon cables from tcon to panel driver board and now I have half of the screen working normally. Any way to tell if the problem is with the tcon or the panel driver board or the panel itself? Should I just replace the tcon and see what happens?
