The light tunnel is either out of adjustment or collasped. Given the age of your projector I would say it is the latter. This will have to be repaired by a tech or you may be able to fix if you can get the part and a service manual.

Why is picture 1/3 down from top and 3" in on right side is a little darker?


Did you move or bump the TV? That can cause misalignment. Did anyone fool with the setup? Get the manual and run through that again. Did you change input source (IE new DVD player, etc)? There is a setup (usually in menu) for slight adjustments to picture in most TVs, like on computer screens adjustments if you ever have done that. RTFM

Dark line down the middle of my flat screen tv


Most LCD and PLASMA sets use two boards (some combine them into one board) that drive the Display Panel (the entire front screen unit) so I would suspect one of yours is bad.

The other unpleasant possible cause is where the left board is connected to the Display Panel (entire front screen unit) you have a problem inside that Display Panel and that is fatal as there is no way to get INSIDE the panel---it can cause both lines and a dark picture on one side of the screen.

Is there an powerful electrical device kept very close to the affected side of the TV? If yes then please move it to a greater distance. This device may be affecting the display.

Toshiba 57LX177: Right side of screen darker than left


I am not sure...but I have the identical problem. I believe the vertical lines are caused by the inverter board and the darkness is caused by the one of the back lights that needs to be replaced. I am tearing my unit apart now and will find out.
