LCD Tv starts to display black horizontal lines after half an hour of use
Hi, I have a sort of old Grundig LCD Led TV that starts to display black horizontal lines after some use. After it's been turned off for a while and cold it does not display any artifacts however after some use it starts to display some faint horizontal lines at the top of the screen and a bunch in the middle of the screen. The longer the tv is on the worse they get until they become very clearly visible. I suspect that heat has something to do with this as when the lines start to appear i notice that the tv's metal case has gotten warm. Could the T-CON start to malfunction when it starts to get toasty? or is this an lcd panel issue? I suspect it's more of a tcon issue as the lines are horizontal and not vertical. Thank you!

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

I have an Siemens HMI with vertical lines on half of the screen. These lines aren't scrambled garbage but rather very regular in pattern and color. I have replaced the LCD with a new one and still the problem persists. I'm wondering if this isn't indicative of a bad video process chip or video memory? Any help would be appreciated. The cable appears to be OK but one pin on the header is unpopulated, though there isn't any loose wire to suggest one broke off or popped out of the connector. In the picture below where the connector is busted out of the side, I did that with my small screw driver...05-16-2024, 06:52 AM -
