Check and replace all the electrolytic capacitors at its vertical output section circuit.

55hdm71 plasma hitachi vertical lins 3 red on right side what do i do?

I dont know what kind of copier you have but white vertical lines are virtually always caused by a dirty charge corona.There is usually a little plastic handle, blue, green or grey, that cleans the charge corona.pull it out ONCE, push it back in and try another copy.If you have an operators manual, it should have instructions for cleaning the charge corona.Good Luck, O'scope

you need to replace the fuser roller in the fuser.

hi,

The upper glass is under the drum unit.

- Remove Toner and Drum Unit and you will see the glass. Try to clean it.

Bye.

Bad lcd display. Take it to Best-Buy.

look for a corona wire, close to the drum

1. Clean the primary corona wire inside the drum unit by gently sliding the tab from right to left several times.
2. Return the tab and snap it into the home position.

Note

If the tab is not at the home position, printed pages may have vertical stripes.

have a Mitsubishi TV 1993. Model CS-35301. The problem is that there is a white line that is running through a blank screen. The sound is fine just no picture. Have you heard of "Vertical Collapse?" I would love to save the TV. Hi nothing to worry just minimise brightness to avoid screen burn. "Vertical Collapse?" means one bright hor.line in the middle of screen. this problem can be solved 1 check vertical yoke connector or wire loose 2 check supply to vertical section which normally comes from EHT transformer check components in vertical section or print loose regards thanks
