(First post!!!!)
I have a friend with a laptop that is having some problems, and I'm curious to whether anyone can help me because he has pretty much scrapped it, and if I can get it to work for fairly cheap, I'd love to have another working computer. ;)

Basically what it does is the screen flickers and scrambles like it has a short in it. I read somewhere on the internet that damaged DC jacks can sometimes cause this. So, my teacher and I tried soldering a new one on. Everything went fine, and we got the jack on very easily after finally getting the board out. Well the new jack did nothing at all. So now I'm thinking the board may have some kind of short in it or something???? Or maybe the wiring that goes to the lcd?????? BTW the screen scrambles at very random times, during boot up, in bios, while browsing the internet, and generally will scramble till the point that it locks up and you cant use it. Alot of times we can trigger the scrambling by adjusted the moniter or tapping the laptop. Anyone with a similar problem????? Anyone that can help??????
I love the site guys, and look forward to joining the community!!!!! = )

Does this do it on an externally attached monitor or just on the LCD? Is this "scramble" lines or is it more like garbled charachters? If its on the LCD and an external monitor its going to be either mainboard or cpu or ram issue. I would then run a memtest to knock ram out of the equation. If its on the LCD only and external monitor works fine maybe check the cable from the MB to the LCD? I know my wife got that same type symptoms (squiglies) on her laptop and I just had to retape the cable down because the glue had come loose.

Yes it does do it on an external monitor.
The scramble is both lines and what I would call "scrambled porn on channel 258"
I'll see if he will just give it to me, or how cheap I can pick it up for.

The laptop is mine!!!!!!
Can anyone get me started in the right direction, I tried switching out the RAM last night but to no avail. I've also played with the cord from the lcd to the board but it dosen't do much when I wiggle it or unplug, plug back in. I really only have problems with it when I move the laptop or adjust the screen angle. I think this could at the very least be a fun project, so any help is 3 thumbs up.

If it does it on an external monitor as well, its hardly likely to be a fault in the LCD display itself.

More likely a motherboard fault.

I kept wanting to think that as well but then why would adjusting the monitor cause it to scramble, and lock up??? hmmm I have the exact model laptop at work sitting right beside me that I'm supposed to do some minor repairs on (spyware clean-up etc) maybe I could use it for a bit of testing........ seems fair enough huh??? Afterall I'm still gonna fix it!
