    Panasonic TX-L47ET5E - Fog all over

    Chassis LA35
    Panel LG LC470EUD (SE)(F2)
    Tcon model 32/37/42/47/55 FHD TM240 Ver 0.4 - P/N: 6870C - 0402C -

    Hi, This wonderful Led tv i have bought broken with lack of some pieces..
    The most annoying one was one of the 2 band cable from tcon to panel, them are always delicate to find on the market and in this particular design it put me on the wrong way let me lost ground in the way of fixage, i was expecting that as usual half tcon connected become in half an image displayed if all is ok but i was wrong, with the ribbon on a side it showed half white half black, on the other side half white half full of vertical lines with bright white/light/foggy tint. Then one day, past months (!) i found out like a stunned that in my house i had a similar Philips tv with a near same lcd panel model, tcon are phisically the same and i have robbed one ribbon for test, with both of them i was surprised and happy to see a full image near completely whiten like a faulty as15 on older lcd's, the Philips 47pfl6008s has this:
    Panel LG LC470EUF - Tcon model 32/37/42/47/55 FHD TM240 Ver 0.1
    Now the tricky part!!...
    On the tcon board there seems to be there isn't a gamma chip!
    Only the big tcon chip, one pmic with all the tensions at their place, one smaller chip with several resistances around, i thought it was it but from a web search it is a Level shifter (TPS65198), no real datasheet available, i have asked TI a copy, there is a small schematic of the chip functions, it seems it manages clock signals on output (maybe for driving gate drivers) and also Vcom level. There are no vgamma TP's..
    Now my request is: can anyone to provide me a dump of the tcon's eeprom of the same tcon? As i suspect some params be changed inside it... Help is appreciated, i can also charge some money to you thinking of save some money on a new tcon.
    Bye!....

    Found very cheap boards on the China market and bought one, there are no Vgamma lines on this design of panel, so i trust in a bad eeprom programming, if the new board will fix, then i put on the site the dump.

      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...

      LED LCD TV Screen Half Black, Half White - Panasonic TH-65AX800A
      by maneatingmonkey
      Any idea what could be causing the left half of the screen to be completely black and the right half completely white?

      No picture from any input or OSD. The audio, however, works fine. Also, the backlight changes intensity along with the input feed.

      I've tested the voltages on all the marked test points I could find and everything reads OK.

      I've tried applying both heat and pressure to the tabs connecting the panel to the buffer boards to no effect.

      Unplugging the white ribbon cables going into the 2 buffer boards on the black half of...

      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...

      by microvibe
      I have a th-41pc75u top half screen washed out can see menu etc vaguely in the whitewashed top half and fine in bottom half. Tv shuts off after few seconds 7 blinks. I disconnected one of the panel ribbons for top half tv will stay on still white washed except for the disconnected ribbon thats black. I tested the su board but cant find a short maybe tested wrong. In the sc board i did notice the white ceramic 2.2k ohm is burnt would this cause this issue or is it still buffer issue....
