    RCA LED60B55R120Q Bad T-CON?

    I found an RCA 60" LED along the curb today. Plugging it in, I received lots of VERTICAL lines, so I thought "bad panel" and almost started to salvage boards and strips. Thinking about the symptoms, I began to suspect a bad T-CON. I removed one side of the connections from the T-CON and got this:

    Removing the other side, I got this:

    With both connected, I received a kaleidoscope of colors and flashing lights - the display wasn't static at all. Here are some pics:

    Question: Is this guy hopeless with a bad panel, or is there a possibility that a new T-CON could save this guy. A new T-CON is $50, which is a lot to pay for a curb find gamble.

    Re: RCA LED60B55R120Q Bad T-CON?

    I would say it is more likely a panel issue as opposed to a tcon. If you look at the second picture, there is horizontal lines thru the connected side which usually points to side driver problems. The first picture appears to show significant "loading" on the drivers in the corner causing total darkness. My guess would be that someone did some "window washing". Since you have the set apart, check the bottom edge boards / tabs areas for "contamination" from "something".

      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...

      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.

      Magnum IA.100 Amplifier Switches on, No Output, Possible Input Side fault?
      by flibidy
      I have here a Magnum IA.100 which belongs to my parents.



      The unit powers on & when the relay kicks in, you get a pop from the speakers (this might sound weird but is usual behavior for this amp). However, you get nothing coming through it from any of the inputs & no pops and crackls from any of the controls.


      Because of the sound from the speaker when the amp turns on I have assumed that the output section probably works but I could be wrong & I'm not sure how to test that side of things further.


      What Ive done........

      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 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....
