    I have three vertical lines. One prominant line 2 inches in on the right side and one on the left side. There is another fainter line on the right sde about 5 inches in. The lines on the right side diminish after several hours. The line on the left stays. THis has been going on for about a month now. I just bought the tv in late Nov, so it is only 5 months old.

    In the last few weeks I have no volume when first turning on the ty each day. I have to turn it off and then on again.

Honestly you have a big problem because the driver IC & Tape Carrier Package inside controller board at vertical area are damage or itself defective could cause you have 2 inches line appear in your display. The best solutions for this replace lcd panel to fix vertical line.

THIS set uses 2 boards inside--one drives the left and the other the right side of the screen.

You have to id which is which (GOOGLE?) AND replace it-every brand has different names for these but it sounds like your problem

Some research (you or me) should give a board breakdown for this model---not looking for main or power board but another like sustain etc. and there will be 2 listed (for right and the left sides)

When I scan a document using the feeder on top, the resulting scanned document has two parallel black lines down the left side of the page. What causes it and what fixes it?

When using the ADF if the glass has dirt on it, as the paper moves over the glass the image is written to the moving paper. The paper is also moving over the dirt specs on the glass causing verticle black lines. It is hard to explain without actually showing you. To fix the problem, lift up the top to expose the glass. Look to the left of the big rectangle glass. There will be a 3/4 inch glass strip. CLEAN IT.

Black Parallel lines across center of paper from edge to edge on Sharp MX-2300N. Lines are about 3/8'' wide and fill about 5 inches in the center of page from left to right.

I am assuming you made sure the scan glasses are clean (the big main one and the small thin **** glass on the fleft side of the main glass.) make sure the mirrors under the main glass are clean.
This is usually caused by the drum starting to go bad and or the main charge unit for the black drum. Knowing the drum counter would help or the age of the drum. open the front cover and remove the big black waste toner bottle. Behind that you will see 4 protruding knobs - slowly pull out each one till it stops and push it back in till it stops. do this several times for each color and black. Clipped onto the door there should be a long thin plastic wand with a felt sponge on the end. If you look under each drum/developer unit you will see a small ****/hole with a sticker of an arrow on it..push the wand into this **** (felt side first - facing down) all the way till it stops and pull it all the way out. do this with each color - this cleans the laser glass. These two methods get rid of most lines. If the lines persist you will need to replace the main charge unit on the black drum.

Panasonic Plasma screen suddenly has a verticle black line


Unfortunately, what you're describing is a repair issue. You won't be able to address the problem with troubleshooting. There is a part inside the TV that needs to be replaced. If you're under warranty, this will cost you nothing. If you're not under warranty the cost will likely be a minimum of $200 parts and labor. However, be warned that the cost could be considerably higher.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

51 big screen apex tv, convergence or verticle IC?

If the lines are thin and close together running horizontally, it may be the vertical driver, but that usually takes out the resistor and sometimes the diode in the B+ for the vert. Also you must replace the caps that caused the problem in the first place.
