1 samsung tv - grey, jiggly, separate lines
How can I remove these grey jiggly lines from the screen?
They appear and dissapear at random times. Tried light hitting it from the back and they disappeared for a moment. Here I uploaded three pictures from the front and back so you can have (I suppose) a better understanding of what I'm talking about. I cant really find the code of this tv but I assume it's 50'+ Inch. If any information is required please do ask and I'll immediately answer them.
I tried disconnecting every cable I could see and reconnecting it but no result.
If similar topics were created before mine, please redirect me there and delete this one.

Hi @edwardnewton ,
usually the model number is shown on the information label that is on the back of a TV.
Do the lines occur when trying different inputs, input types or signal sources e.g. HDMI, coax, Component video, dvd player signal source, antenna signal source etc?

Nonetheless I'll see what I can find online.

@edwardnewton you can cover the board with some heat resistance foil (aluminium foil) with the exception of the BGA. Keep that exposed including the edges of it. Then borrow your significant others toaster/oven and heat it up to about 430 fahreneheit for a few minutes. Let it cool down by itself without moving it around to much. Not the greatest way of doing it but I assume that you do not have the proper rework station available to do it the proper way. Biggest issue with doing it that way is that the substrate of the IC gets warped and/or the IC gets ruined. Anyhow......
