HP Pavillion DV4 Laptop Needs Screen Cable...

Have a HP Pavillion DV4 Laptop, screen started to go whacky about a year ago, but wiggling the cover would fix it, over time got worse to the point it completely stopped working.

I took the unit apart, put it back together and WHAM, it was working fine... until I moved the screen and it started to go haywire again, lines, a semi blank white screen, etc. External monitor works fine.

The screen is a complete b*tch to work on, and I suspect it's a damaged cable. There's a cable bundle (it's not a ribbon) that winds around the lid hinge - I think it's frayed.

Nice laptop, can handle most games and loaded with features. Would like to fix it. Anyone have experience with an HP laptop?

HP Laptop screen dead after child bashed keys.

My next door neighbour just gave me his laptop to have a look at, an HP Pavillion DV6000, which his baby has managed to 're-adjust'
Apparently his baby was bashing away on the keyboard and now when it is switched on all keyboard lights come on, the laptop makes 3 very loud and intrusive beeps (beeeeep....beep.beep) and the screen is completely dead, no flickers, no nothing.

Any idea what the problem could be and how to resolve it?
