Try unplugging power cord, to reset the projector, try also switching input selector and controlling the video cables.

If ou still get the vertical bands, then ther eis an internal fault, probably in the image circuits on board.

How do I get rid of this one vertical white line on my toshiba TDP-S8


take the cover off, disconnect the the connection on the rear of the lens assy from the main board, clean with an approved electronics cleaner and then reconnect. Sometimes this fixes the problem. If it doesn't, then the DMD on the rear of the lens assy is bad or the main board is bad. Hard to tell without a test fixture.

Unwanted verticle line on fax copies


Most likely a fax has been sent or a page copied with 'white out' (Liquid Paper), still wet on the page. As the page feeds over the scanner, (a narrow strip of glass that runs across the width of the page along the feed path) the wet liquid paper comes off on the glass as a thin line and dries. Thereafter, when copying, scanning or sending a fax, the scanner light does not go through the liquid paper streak and the result when printed is a thin vertical line that runs the full length of the page. If this is the cause you will also find that faxes you send to other people will also have this line (although faxes you receive are not affected by this problem with your machine).

To fix the problem: follow the path that the paper travels when sending a fax or making a copy, until you find the scanner (narrow glass strip). Take a clean, soft cloth and a small amount of methylated spirit (or white spirit) and remove the now dried Liquid Paper from the glass. Clean the whole strip ensuring that the glass is left clean and dry.

Thin black lines: projector TDP-ET20


Do a factory reset to the projector. In my experience that fixes alot of image problems.

Hi there

This would mean that your Projector is still under warranty.

The problem you are describing is a faulty Mainboard - which fortunatelly for you is covered under warranty.

Two or more black bands appear


Try resetting all parameters to factory settings. Do it once and then set your personal settings. Then, reset to factory defaults again.

Black lines


There is a thin strip of glass that you will see when you lift the top feeder. There is most likely white-out on it.

When you use the top feeder, it doesn't use the large glass, it only 'rolls' the original document over this small strip of glass.

Hi there

Have you tried using another input like the Component instead of the DVI. See if it makes any difference.

If not it could be the DMD or your Mainboard.

Most of the time it is the Mainboard - Home Theatre Projectors come out with awesome DMD's , so I doubt it to be the problem.

Hope this is usefull !
