So I had my LCD screen on my laptop broke so for a while I was plugging my pc into my tv to use with an hdmi cord. No issues. But then I started seeing these red lines coming across my screen, red and green pixels kind of flickering around the edges. Over the weeks it kept getting worse. Where e red lines would cut my screen in half, one side would start violently flickering and moving left or right. It got so bad eventually it just stopped displaying my pc all together. I run my games at a different resolution, and when I started those up and then plugged my laptop in it would work fine. For a few days. Then the red pixels started to invade my games and I got sound glitches as well. It got so bad the only thing the tv would display now was the start up screen,but now it won't even do that. When I plug my pc in I just get a no signal message. I tried using a different cord and trying all 4 hdmi ports on my laptop. No success. I have no idea what it could be. Sadly I don't have another monitor in my house to test this on. Any ideas?

Have you tested a different HDMI cable?

Unfortunatly then it sounds like your Video card is crapping out.
If the laptop has dedicated graphics then you might be able to buy a replacement graphics board.

Otherwise if it is integrated graphics then you would have swap out the entire motherboard which i a good $200-300 and requires the ability to fully disassemble your laptop.
