Horizontal Lines Fault on Samsung LE40A559P4F LCD TV -Fixed by tapping

Hi there. I have an old Samsung LCD TV (LE40A559P4F) that has an issue with it. A block of flickering horizontal lines appear on the right hand side of the screen. This often appears shortly after switching it on first time of the day and is currently temporarily fixed by tapping on the bezel. I have posted a video showing the fault: https://www.youtube.com/watch?v=wVX4JDKc...

After tapping the tv "the right way" the screen seems to work as normal for most of the day. Every once in a while it may require another tap if the horizontal lines come back.

Something to note: for some time the tv was talking a while to switch on, taking longer each day. This is when I noticed the horizontal line fault starting. I had recently replaced the capacitors which has solved the problem of the tv taking so long to switch on but it didn't solve the problem of the horizontal lines.

Any help / advice would be appreciated.

@bm7412 remove the back cover. See how wide the area of the horizontal line is.? Check your flat ribbon cables as well as the connectors to it. This appears to be either cold solder connections or loose connections of the LCD driver board cables to the panel. Careful, those are “glued” Post some pictures on here once you have it open.

Ok the back is still off of the TV and I’ll need to get some pics for you when I’m done with my work shifts. Just to clarify, when you mentioned those were glued, what part did mean exactly?
