Turned on the tv this morning and only the top half of the screen looks like 3D. The bottom half is okay. On a black screen there is a big green line dipping from the top about four inches at its widest point. Our manual does not address this. Tried Perfect Focus and it does not show any progress. Tried the Convergence and no luck.

May I know what portion on the screen turned to black, is it top half, bottom half, left/right side. Also please confirm if your TV's model no. is 50PQ30C, it is printed at the rear panel, manual, and receipt.
If your TV looks 3D, warped, or distorted it likely has a convergenge problem. If however it just looks dull, washed out, redish, greenish, or blueish or if it looks like objects on the screen have halos the fluid in the lens has soured. You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

The cost I don't know, but this can be fixed. I'd say shop around a bit. Make sure the repair person is certified for your TV's manufacturer.
There are generally 3 lamps in projection T.V.'s, Red, Green, and Blue. They have to be aligned for the TV to project a clear picture. A credible TV repairman should be able to fix it. Depending on if it's new enough to be under warranty they may cover it as well. Really the only reason to get rid of it is if you want to get a new TV anyway. Depends on the cost of having the lamps aligned.
If the loss of picture is either on top half or bottom half of screen. there are y buffer boards that go from top to bottom on left side of screen when looking at back that control those sections. when there is loss of half of picture then buffer associated with that area would be at fault and would need to be replaced. when i see a degrading symptom such as loss of picture on top half or bottom half leading to no picture issue normally you would check heat syncs on y sustain board and if not heating up after a few minutes of being turned on would recommend replacing y main and both y upper and lower y buffer boards as they complete a circuit
This is a convergence problem and is either bad connections on the convergence ICs or defective ICs. If you feel that you can solder, you should be able to repair this yourself. First try resoldering the pins on the convergence ICs. If that fails, replace the ICs. These ICs are large black ICs attached to a heatsink and should be marked STKxxx.
Keep us posted.
