What would be causing my monitor to do this?

[Inflam3s]

Hi all, stumbled across this forum looking for help with my secondary LCD that went all white.

Old ASUS VW222U 2008 vintage, firstly went completely white, so i thought some of the caps may have popped. but after pulling it down checking it and putting it back together, i can see a picture on the screen, albeit the bottom 2/3 of the screen being stupidly bright like the brightness/contrast controls have gone out the window.
Any Picture can still be seen across the whole monitor, but the bottom bit is just overly bright.
I've checked all my capacitors etc with a multi meter, just wondering what else could cause this extreme brightness on just the bottom bit of the screen.
The first picture is meant to be a completely black background, and the other 2 show the desktop with partial normal colours and the rest saturated with brightness.

Regards, Dave.

Remove and re-seat the LVDS cable -- runs from the top of the LCD panel to the main board.

Thanks, ill give it a try, any ideas why it would have gone completely white as if capacitors were bad, or could this cable do the same thing?

It's very rare that capacitors would cause this issue. Most often it's the contacts on the lvds cable getting oxidized or not making good contact. Reseating the cable sometimes fixes this.

Tried re-seating and its still doing the same thing, is there anything else i can try or is it just one for the dead pile and go buy a new one?

Cheers for the advice

Maybe it's the logic board?
