      ACER BM320 Monitor - Horizonal Flickering Lines After a While
      by reessi
      Hello,

      The monitor started off showing flickering thin (1 pixel) lines horizontally every say 3mm..

      They are black on the right and gradually fade to nothing on the far left.
      They start either after 5 mins or up to 2 hours after so annoying for testing.
      They flicker continuously very fast! With a slight pause milli-second every second.

      Initially I cleaned the LVDS cable and connected to the T-Con and then it worked fine for 3 weeks but not sure if this was just co-incidence.

      I tested each half by removing the first the left flex from...

      HannStar Hanns-G HC194d LCD monitor repair
      by momaka
      Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

      Hi, I have this tv a LG 55UH661V that show flickering images and lines. I tried to take off one at time the right and the left ribbon cable and put the tape for ask the pin…but nothing working. Or I stop to have picture or still flickering. Someone can help me to understand what pin I have to mask? What I notice the buffering board, the flat cable becomes very hot, I don’t think it s normal, I’m talking about the orange flat cable soldering on the buffering board, both side are very hot. I give you the photo with both the ribbon cable on and a photo with the right off and with the lefts...

      Mi Curved Gaming Monitor 34" - Horizontal lines
      by Kikerumbo
      Hello everyone,

      Thanks in advance for any help you can provide.

      I have a Mi Curved Gaming Monitor 34". A few weeks ago it started to show (or not showing) horizontal lines. Of course, it's outside of the warranty period.

      After some hours of reading and watching videos I disassembled the monitor and checked the ribbons that go from the TCON board to the panel PCB. If I disconnect the ribbon for the right side of the panel, the other half shows a perfect image. I ordered a "new" TCON, installed it and the issue persists so that tells me it must...

      TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
      by howardc64
      All left and right refers to looking from rear of TV (or looking from front with TV upside down)
      • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
      • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault
