If I remember right, you have to hold in both of the keystone buttons for 30 sec. As for the line, I'd have to guess it is the main board or the dmd board on the back of the light engine. Very expensive to fix..However, if you are good with taking things apart you can clean the connection between the light engine and the main board with an approved electronics cleaner, make sure it is dry and reseat the connection between the two. Sometimes thats all it takes.

I have multi colored vertical lines across the entire screen. The menu screen is perfectly legible when selected on the remote and will go on and off like it is suppose to.


If this tv vertical colors lines problems happen by itself,tv problems not causes by u or an object by hitting forces to the tv LCD screen panel itself.The tv board that call the T-CON board it is dead,this board sit in the bottom in the middle of the LCD screen panel.Must be replaced the T-CON board to solve tv vertical colored vertical lines.Tries websites like Shopjimmy.com,Ebay.com to buy a whole new refurbish T-CON board for the replacement.If causing by u or an object by hitting forces it to the LCD screen panel itself.The tv not worth a whole tv anymore,because by replacing the tv LCD screen panel will cost the same as a new tv.

I have 2 lines running down my monitor screen. One blue, one green.


They are vertical lines running from top to the bottom, then it can be loose ribbon cable or dirty connectors, or failed LCD controller board (part of the LCD panel assembly, whole panel will have to be replaced).

It sounds like a vertical deflection problem. You mentioned you had a white HORIZONTAL LINE in the middle of the screen. If this line runs from left to right across the screen it's in Verticla deflection. If it runs from top to bottom, it's in Horizontal deflection. I am assuming the problem is a Vertical deflaecion problem. The repairs necessary are most likley to replace the vertical capacitors or the verticla deflection chip.
Good Luck

Discolored image and lines...


I also am having the same problem. at first it only showed up after the projector was on for about 15 minutes. Now I get a purple vertical bar on the right of the screen. I also get vertical green bars spread across the screen.
Does anyone have a diagram of how this machine is assembled?

Since Intermitant always inspect the vert ckt for bad solder connections. If not replace the output IC they're cheap and most likely the problem If you still have lines on the top or bottom I would replace all of the electrolytic capacitors in the vert ckt also. Without much test equipment rebuilding the whole little ckt is the best way to go.
