I have a 820-2915-B Display is flashing between colors like as if it was in a ASD video test. iv tried restarting many times but no change. i made a video but had to convert it to images (its about 20 sec of video) because idk if i can upload videos or not? if so what file type? i have yet to run asd tests so i will run it as soon as i can get to it and will update if i get any info there.

Gurmon You say LVDS Cable? but this is on a working test screen. it does this on multiple screens, but i did not test external at the time (now im thinking why didnt i hahah) perhaps LVDS connector on the board is likely

If the lvds connector is fine, then i would suspect the GPU mux. Also check out U9270 area.

Yes it does. and if i move the screen up or down it makes dif lines and changes colors. it seemed to not be switching colors on this test screen but mess up the color if you move the screen. and i would think that it is the screen is how it makes me feel but i plug a working board into it and it works normal so i cant be the screen. could it be the lvds connector on the board?

The colors changing when you move the screen is probably and indicator of a bad LCD connector or one of the coils in the LVDS lines near the LCD connector. Poke around the LCD connector and see if anything reacts.
