My TV started about a week ago with a horizontal line about 5" from the top. The line is very thin. A few days later 3-4 horizontal lines appeared at the bottom. These lines are black and very distracting if you focus in on them. I contacted the manufacturer and was told that the screen needs to be replaced. The TV is not even 1 year old. They said that they will replace the screen for free. I would have to pay for the shipping of the TV to the manufacturer which will run about $1,300.00 - $1,500.00 with insurance. Is there any other way to ressolve this issue?
I'am an electrical/electronic engineering student.I come across a problem on a computer monitor which develops horizontal lines across the screen of the monitor.

Re: horizontal lines on Screen
Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages. Good Luck!

The flybacktransformer is normally at the Horizontal section of the
monitor's mother board, It sounds that your flyback transformer might
be the cause, bright
intensive white lines can be fly back defective. . Try changing your
flyback cause I encounter a problem similar to this and it works.
It is the problem of monitor pcb in vertical section.check vertical ic for dry soldring. Resolder the ic if problem still on then change ic or check components related ith it. check continuity of vertical deflection coil.
Hope this be of initial help/idea. Pls post back as requested, how things turned up or should you need additional information.
Good luck and kind regards.

Your comp's video card refresh rate (in Hertz, abbreviated Hz) may not be totally compatible with the monitor. Check the properties of your video card, and change the refresh rate (you may have to look around for it) to 60 Hz. This is a pretty standard refresh rate that works with just about every monitor. If it's already there, I'm afraid someone else will have to try and help!
Hope this helps, and please rate my answer, good OR bad.
I tried this and it has worked temporarily by banging the monitor not great but it did work, no tech knowledge if there is any other advise please email.
Hiyama Monitor Model: Vision Master 17 (8617E Chassis) Horizontal dark line across screen shadowing text or other complex display data - giving appearance of 3D grooves or just dark lines on light background - temp fix (few minutes) by banging monitor or jiggling the video cable (thats what threw me for a while) Removed tube base board and ran over disc capacitors and other solder joints whether they looked dry or not. No re-occurence in 2 weeks of daily use. Seems to have fixed it. (Be prepared for a lot of metalwork and screw removal when opening one of these up - I still havn't figured out how to get the PSU/main board out of one !) (John)
Unfortunately the LCD is going faulty.. one or more of the "Driver" transistors that operates the LCD elements RGB, have faulted ON.. perhaps this link may help fix it. Otherwise :(
I know I have seen thin lines in the past on older CRT monitors, these are usually wires which support the aperture grill.
LCD is just a panel so this must be something different. What color is the line? It is probably an error in the scanning process.
