Unfortunately the only thing you can do is get a new tv. You can check if you still have your manufacture warranty.

How do I fix my Sharp tv model LC-42D62U? On the tv screen now shows horizontal lines with repeating ghost images.


Hi Paul,
The horizontal lines on the screen are virtually NEVER caused by a bad T-con board. These horizontal lines indicate a defective LCD panel (screen). The Screen has small ICs that become defective overtime and that it isn't fixable unless replacing the entire screen.

Dark lines appear on each page I print on the printer. I have cleaned every roller, dumped the old toner and added new toner.


Are the lines vertical or horizontal?

vertical lines can be caused by several things.
Since you said that cleaned the rollers, then here are other options
1: Most common is a bad toner cartridge.
2: try cleaning the fuser entrance guide.
3: could be a defective formatter - formatter replacement the fix.
4: worn fuser. fuser replacement is the fix.

horizontal lines are probably repetitive down the page, and are usually caused by a defective toner cartridge or fuser assembly. occasionaly a transfer roller will cause it as well.

Toner loves to get baked onto the fuser and cause all kinds of print problems. Not much you can do but to replace the fuser when this happens.

This is a problem with the vertical circuit that is usually a defective vertical IC. This part costs $10-$20 and is easily replaced. Sometimes there are capacitors in the same circuit that need to be replaced as well. Dan
