    Emerson 40" LCD Model LC 401EM2F Possible purchase

    I acquired this 40" LCD TV Set that has a cracked LCD panel, in search of a replacement panel I found another identical TV set for sale with this symptom (Horizontal Line on the Screen, see attached picture) I have been under the impression that defective panels have one or more vertical lines and that a horizontal line could be a possible T-CON Board problem? any advise is appreciated. Does anyone know of a LCD Panel Supplier? Panel # is
    Samsung LTA400HM09 7HBH53036G F02

      Nope, on an LCD, any line in any direction is a bad panel.
      Only with plasma displays is a horizontal line possibly a bad buffer board.

          Thanks Tom, I haven't disassembled an LCD TV all the way down to separating the LCD Panel as of yet, but I may do it on this one if I can't find a replacement panel, could you tell me if the tab bonds are only located where the ribbon cables are coming from the T-CON Board then attach to the LCD Panel?

              It is not the tab bonds, well, probably not. More than likely it is the actual chip on the right hand side which has failed. Technically this chip consists of just resistors to the VCOM on the panel. It's possible you could substitute an actual resistor in, but I doubt it would work well.

                  The TV with the Picture in Post#1 was on Ebay and has been sold, but I have the same model with a cracked LCD Screen as I have posted here, so now I either wait until I can find a good Panel or just tear this set down and salvage all parts to sell or save for possible future use, and I could also disassemble the LCD Panel and possibly save the Back Lights/Tubes.

                      I sent an RFQ for a for a quote, they say the one company has 1300 of these Panels, do you think they will sell just 1 to me? Here's the Link.

                          But is it really worth it???

                              I sent them a request for a price quote, I'm waiting on a reply, I imagine they will be sky high with the price but we will see.

                                  Samsung UN50TU8000FXZC shows thin horizontal green line when warm
                                  by cubytus
                                  Hi to all,

                                  I was given this TV, an entry-level 4K 50" set. Some have criticized its lack of contrast and relatively poor colour rendering, but for my needs, it's very decent.

                                  I reset everything to factory settings, but this line keeps on fading in and out when watching a streaming channel from the Tizen firmware. Interestingly, it only happens when TV is warm, after about 1h45 of it being turned on.

                                  Watching a movie from an external source doesn't trigger the line as easily (needs 2 hours), and from a normal viewing distance, is hardly noticeable. It...

                                  IR night vision goggles to find shorted panel line?
                                  by Lee M.
                                  Has anybody tried to use IR night vision goggles or other thermal imaging device to find a shorted line in a ribbon cable going from a panel driver board into the panel? I would think the shorted line would get hotter than the other lines and might just show up on a thermal imaging device. Just wondering if anyone has tried this and if so did it work?

                                  LG 49UJ6500 LCD panel lighter band that goes away
                                  by howardc64
                                  49UJ6500 LCD panel has a lighter band on top when first powered on. Goes away (or gets much fainter) after TV on for a few min. After powered off for awhile and power back on, same band appears. If powered on immediately after powering off, no or much fainter band. Running the latest firmware.

                                  Disassembled the TV and lifted the LCD panel during testing. Band is on the LCD panel (can see the band on the panel as I lift it slightly) Backlight is perfectly even at the top edge. Double checked LCD panel alignment in the frame and is perfect but since band moved with the panel, its on...
