I just replaced my dell laptop screen and i have a squiggly line

Check and replace all the filter capacitors at its main power regulator section circuit.

most likely a loose connection if it is flickering.. if there are red squiggly lines usually means driver issue.. and if there are blue banding lines, typically means the chip is overheating/desoldering.

It can be that the video card in bad or any electrical part need to be fix and i recommend to send it to a repair shop.

Try to connect an external monitor to the laptop if the lines are there then it's the video chip on the motherboard. But if you don't see ant lines on the external then it's the LCD on the laptop and it can be replaced. If you can't perform the work yourself take it to a local repair shop.

bad RAM on graphics card. replaces graphics card

Hi. Does it happen in all videos titles or just one film? If it only happen in only one video then the film or video is corrupted. If it happens in all videos when you play then try reinstalling the graphics driver. Hope it helps!

Sounds to me like your inverter has gone bad. Typically it's situated just below your LCD. To get to it you will have to take out the screws around the LCD bezel. It's a long, skinny circuit board that the LCD plugs into. You can usually find a replacement on Ebay. Just be sure that you're ordering the correct part, otherwise it may not fit or work properly. I've also had times when the entire LCD was going bad and the display was full of squiggly lines. It's hard to say which one is the cause. I would try replacing the inverter first. That part is usually much cheaper than the LCD is.

Hi Fkanode.
The failure(s) in your TV is related to a part called light engine or optical block and Sony TVs are known for these kind of failures with the video showing with different colors or lines.
Check the link provide for more info or if you would like to try fixing the TV yourself.
