Re: 42" LG plasma
It sounds like a bad panel, which is not what you want to hear. Replacing the panel on a Plasma TV usually costs more than just replacing the TV. However a bad panel causes vertical lines exactly as you describe.

Sounds like COF (Chip On Film) strip fault. Check this link for more details. There is illustrations [screenshots] and reasons to plasma displays. Check it out, and compare them with your TVs fault. Pull up older posts there.
1 - The cable that connects your screen to your laptops motherboard has come loose. If the problem is intermittent or can be rectified by moving the screen / holding the laptop upside down then its this.
2 - The graphics card on your laptop has a fault. This is quite common with laptops that overheat.
3 - The LCD on your laptop has developed a fault.
The first issue can be fixed by taking the laptop apart and checking the cables, but beware - this is normally quite a complex job. The second and third issues will require replacement parts which can be quite expensive. Try to get a quote from a local PC technician (don't go to PC world...) and weigh up if the repair cost is worth it or wether you just just put that laptop on ebay (list it as faulty) and buy a new one.
one wire coloured red is connected to the live line(soldered)
second wire blue in colour is connected or soldered to the neutral line.
third wire coloured green and yellow is connected to the earth line.
Its not problem with any setting. Its an internal fault. Vertical scanning output stage has failed in your tv. You have to check the soldering of the vrtical output ic if there is any dry soldering this can happen. try to resoder all the points in the vrtical output stage. IF doesn't help then you have to change the vertical output ic. Have added the picture of the dry soldering point how it looks like. If you need further assistance feel free to contact throug FixYa.
you should beable to get it fix, it depends on how much you paid for it becasue they may charge you alot to fix it and you could go out and buy a new one for that price.then again...if you go on line and type the name of camera they may have a number to contact them and they will let you know f they can fix it.

sounds like you have a vertical sweep problem. Where the fault lies cpuld be the vertical output IC the verticle b+ feed, could be the capacitors in the vertical circuit?? Your gonna need to troubleshoot thr vrtical circuit if your not a tech thin my advise is to take the set to a pro for sn est. Good Luck
