You might need to adjust the red screen drive control, turn the Red down and see if that clears it out. Sounds like the Red Tube is over driving the Green and blue Tube.
Find the Focus and screen control block there will be 3 controls on Top 3 right under them R-G-B they adjust the Focus to each tube and screen drive for each tube. also you need to clean the lenses off top of each tube they get dirty and dusty and it would help to clean the mirror

Sony kdf-e50a12u rear projection lcd bravia. red shadows


This is due to you having a projection tv, some projection tvs are really bad for game playing and especially if you have a hdtv. even in the p23 manual it says that you shouldnt use with a projection tv cause it can damage your tv's screen permanently. I personally still play mine but, thats likly the problem.

I had the same problem with my tv. It is a convergence problem but if it has convergence settings in the menu and they don't fix it, you need to clean the lenses with alcohol and q-tips. I did it with the tv on so i could make sure it was clean by the absence of streaks on the lenses. The outer screen (if it is smooth) should be a protective screen (just plexiglass). You can get a replacement at a glass store be sure to keep the old one so they can cut a piece to size. It the screen you are talking about has little lines in it your freznel lens is scratch and it will be difficult to find a replacement. Good luck!

Picture shadow on rear projection Sony big screen TV


You have 2 distinct problems that should be addressed separately. Please repost the Samsung problem. I will address the Sony problem here.

If the "shadow" makes the picture seem somewhat of a 3D one, the problem is with the convergence circuit. This could be as simple as bad connections on the pins of the convergence ICs or defective ICs. If you can solder and would like to attempt the repair, update this and I'll provide more details and instructions.

LG rear projection


Hi, I used to work in Best Buy and one of the key things about rear projection TVs and the reason they push those service plans on you is that the tubes/colors need to be calibrated each year. You can do this yourself by checking out the following website:  

http://lgknowledgebase.com/kb/index.php?View=entry&EntryID=3229 

If you are not able to adjust the convergence using the remote you will need to replace the convergence chips. 

Typical Symptoms

1) Convergence menu does not work for one or more colors.  
Such as: Red moves up,down, but left or right fails. 

2) Screen is bowed looking.

If you have one or more of the problems above you need to replace the convergence chips. You can get a kit and instructions from www.TvRepairKits.com  

Hope this helps :)
