I have a Toshuiba Regza 46 in screen that has a number of thin lines on the right handside of the screen and a thick black line on the left side after 20 minutes the right disappear but the left remains....


Lines can be cause by your T-con board or by the screen itself. The only way to know is by replacing the T-con board. If they go away then it was the T-con board if they do not it's your screen that is bad. When changing the T-con board it is also a good idea to change the ribbons that connect it to the screen. You can get parts from www.interliquidparts.com

Black line 2 inches wide on right side 6 inches in


hi all .ive had the same problem,a thick black line down screen.sometimes it flickers from top to bottom and other permantly in view.but i have solved it.forget your ic boards and taking apart tv.have you got either a ps3 or wii connected to tv.if so unplug power lead from socket and relocate in seperate socket.make sure the lead is completely free of any other leads and you might just find this works.i think the power lead creates some sort of frequency that the tv picks up .good luck hope it works

42 inch samsung plasma tv black vertical lines


Hi, Depeending on the thickness of the lines matters. If the lines are Black and about 1-2 inches thick it may be a bad bottom buffer board or a bad panel (screen).
If the lines are thin 1/16 to 1/8 inch it is most likely a bad panel.
You can open up the set and depending on the model, see the thin board/boards running across the bottom with ribbon cables going to the panel. You may be able to attempt reseating the ribbon cables, but be careful as some retainer plugs break very easy.
If the lines are thick black and the reseating doesn't correct it you may be able to buy the coresponding buffer. Unfortunately some bottom buffers are actually part of the panel. If you are not comfortable taking it apart then call a professional but be aware labor charges start around $200 not counting parts, panels start at $600 up to over $1000
hope this helps
Thanks
Eric

If these are thick black lines, this is most likely line frequency noise entering the set. you may have a leakage from the DC ground on the secondary side of the powersupply to the AC side, or a bad filter capacitor(s). Most of the time it is the filter caps that give these types of problems. If you are connected to cable TV service, or an outside antenna you can also have this problem from an AC ground loop return. Also if there is a device such as a VCR connected to the TV and it has problems, it can cause this as well...
