Half of My Screen is Different Colors

[MegamanMaverick]

Sorry if I answered the product information incorrectly and unclearly, but I still hope someone can help. Almost all the time, half of my laptop shows randomly colored lines and I have to either hold the screen or hit it lightly for it to show the full screen. It's a mirical when it actually shows the full screen like now. Almost nearly the slightest movement will cause half of the screen to go crazy with colors. I'm pretty much afraid to move it or put it down unless I am going to have to not be on it for a while. I have had this laptop for about four years, if that helps. The laptop will sometimes show rainbow colors only in the middle of the screen rather than on the whole half of the screen. One side is always uneffected (The left side). It began about a few weeks ago, but wasn't a big problem until now. I don't take it much out of the house. While carrying it from one room to another, I may have accidently hit it (if that helps). Would I need tools to fix it, an expert to fix it, or would it be better to buy a new one entirely?

Hello there. Thanks for posting. The description pretty much explains that there is a hardware problem (Display Flex cable - Video connector cable) which needs to be replaced. The cable causes the weird rainbow colors when the display is moved forward and backward. The PC is 4 yrs. old. You can still contact HP Phone support to get it fixed or check locally for repairs.
