Hi all.

I've been working on my projector for a couple of days now and was almost finished when i mounted the lcd and connected everything to it an it worked but it was a 1cm line in on 1/3 from the bottom where there where no image. The strange thing is that it's not completly colorless but its moving some colorbars in it but not the right image. Is there any hope on fixing this or is it just to start looking for a new lcd?

Thanks Jensa

Check the attatchment of your FFCs. There is a possibility that you're just getting poor contact in one area, causing the problem.

Also carefully inspect the edge connectors for damage. This kind of damage looks bad... hopefully you will be able to find a loose connection somewhere. If not, then it's time to go shopping.

This is quoted from an Lcd manufacturers page:



Typically there are row drivers and column drivers that burnout and cause a given row or column not to be addressed - simply stated, it is not connected electrically any more to the display. If a block of lines goes out, the entire driver has probably been damaged. One possibility is that the TAB driver has disconnected from the surface. The TAB driver is connected to the transparent traces on the glass using an anisotropic conductive film (ACF). Sometimes that film will be damaged and a particular connection between a row and a column in the driver can be destroyed. If you have a row or a column driver damaged, the driver needs to be replaced. In a CG silicon display where the driver is on the glass there is no repair. Chip-on-film drivers can be replaced in their entirety.

The real issue is what causes these failures. They are typically caused by electrostatic discharge. You should make sure that your manufacturing area is properly handling displays especially before they are connected to a ground. Make sure that personnel handling displays are working with wrist straps and are working on a conductive floor. An ionized air flow environment with a slightly elevated humidity is recommended for handling displays that are not yet grounded in a system. When removing protective plastic film, remove in the direction away from the drivers and should remove it at a relatively slow rate to eliminate the build up of a strong static charge on the display. When these precautions are taken, you should see minimal or no damage to row or column drivers and most line-out problems will be eliminated.

...I guess this Emphasizes the importance of grounding yourself
before even considering taking apart those LCDs...

Today i mounted everything again nad checked alla connectors but they seemed fine bu the line is still there though :'( The strange thing is that the colors on the line matches the colors on the rest of the lcd and when you move the mouse cursor there they move with it but obly vertical colorbars. :s

Well, I've orderd a new lcd which should come this week
