    Image Retention/Burn-in on LCD set....?

    This effect--May just be the panel itself.

    The set is one of those cheapo Chinese 'NEON' make sets, a 32" that was dead.

    The PSU caps were toast. All replaced, now set works and has a good picture....

    However, There's a thin boarder/line around the picture about 1/8" in from the edge/plastic bezel all around that is darker and worse at the top right-hand side, either side of this line, that has indistinct edges, the picture is fine, Bright and correct.

    I got this set from a Tele-advertising Co, they use TV sets at various places running ads for who-knows-what.
    A Pioneer 50" set I was offered with a different fault showed a very hideous and very burned in image, but oddly no boarder around the picture....

    Maybe its just another odd Chi-Mei Panel-fault to add to the list.....

    Not ever seen an LCD set with what can be called a Proper Image-retention or image-burn of the screen, I was thinking that it wasnt actually possible on an LCD.....

    What do you lot reckon?
    TELEFIX

    Man!

    I got s Samsung doing this too, I should take a photo and we can compare. The funny part is the right side looks better then the left the whole picture looks fine but if you look upclose on the left side it looks like the LCD looks like t-con misfire as you can see it move/flicker. I am not sure what to call it but at normal viewing distance it looks totally fine.

    But I too have a perfect 1" clear boarder around the edge too.

    But to answer your question, yes LCD TFT panels can get burn in, just not as fast as a plasma.

      T-con suspect issue. Both ribbon cables no picture. One ribbon cable ok. (58pus8545)
      by Tr0ll
      Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.

      The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.

      Original T-con:
      Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.

      First replacement T-con:

      I thought it might be t-con and ordered new t-con from china(supposedly tested)...

      Hitachi 32HAE2351 Vestel 17MB171 - Rotate Image

      Hitachi 32HAE2351 Vestel 17MB171 - Rotate Image
      Mainboard: VESTEL 17MB171 Chassis: VES315WNGB - 2D - N52
      The TV was stuck on the logo and I couldn't access the update menu.
      I couldn't find the firmware for the Hitachi 32HAE2351 and updated it with the Toshiba 32WA2063DG - Vestel 17MB171 firmware.
      The image result was good, but the image is inverted.
      The image rotation/mirror function doesn't exist in the Menu Server. I can't correct the image.
      Do you have the firmware for the Hitachi 32HAE2351 - Vestel 17MB171 motherboard or a solution to rotate the image in...

      SAMSUNG UN55KS9000F picture fades then distorts into vertical lines after 20 seconds
      by JJAAMM
      This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.

      Problem
      TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode...

      by TR103
      Hi, I have a Samsung UE50TU with:
      - sound and backlight, but no picture
      - when it arrived, it had a picture for a few seconds
      - it keeps rebooting
      - without ribbon cable between the two panel boards, it does not reboot but I have no picture
      - without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
      - when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.

      - without cable between mainboard and lcd panel and with a jumpered...
