Check the drum life and replace it if near end. Clean primary charge corona wire if the drum is still new.
Most likely the drum cannot be cleaned properly by the cleaning blade due to wearing or cannot be charged before developing due to dirty corona wire.
If this cannot help check the fuser's hot roller for tearing/scraching and replace if necessary.

I got multiple thin colors on the middle of the screen


My 3-year old 52-inch Toshiba flat panel TV (Model # 52RV53U, Serial # AM409000295) developed a display issue (purchased Aug. 2008, manufactured July 2008). Vertical multicolored lines appeared on the screen just left of center. The band of thin vertical bars is 5.5 inches wide. The lines are about 1/16-inch wide. They are stationary, always exactly in same place. They over-ride any other picture on the screen (no transparency). They are there all time even with no video inputs to the TV after the unit is turned on. See picture #1. The TV works well in every other respect, but, obviously, it is annoying to watch the picture with the color band blocking about 1/6 of the picture.

I already swapped out the TCON board with no improvement and replugged the TCON board cables with no improvement.

Most likely it is the flat panel tab bond failure (panel made by Samsung). Further updates will be on my Facebook page.

About 1/3 of the way over, one vertical line of text in my resume seems to be bolded going down through the entire document. The rest looks fine, any ideas?


Sounds like a smudge on the encoder strip. The clear plastic behind the carriage assembly. if you hold the paper at the paper path the encoder strip will have the smudge in the same area as on the paper. you can clean it with a damp Q-tip...gently though

4 - black ink smudges (1/32" wide x 1/16" high) in right margin


Very nice trouble shooting. The image defect you describe point to the OPC or drum unit this is essentially the toner cart. In your case black. Measureing the distance between repetitive defects is a sure way of diagnosing problems such as yours. Again nice work.

Google repetitive defect ruler for your model to help in the future.

Hope this helps

Vertical line on LCD TV Panel


Had this same issue on right side of 52" about 1 inch from side but had 3 vertical lines that disappeared after 40 minutes. Have Samsung LNT5265FX/XXA and about 16 months old. LCD Panel itself had to be replaced to fix it, fortunately had extended service plan
