P52926 I am told I have a vertical alignment problem but am unable to figure out how to fix it. The picture dips in the middle and the letters look like a rainbow.

You do not have a vertical problem, you have convergence concern. Try unplugging the TV for 5 minutes. If no fix call only an authorized service center. GOOD LUCK!

You are describing a convergence issue. Rear projection CRT sets use THREE separate color 'guns' that need to be aimed properly every so often, sometimes every month, sometimes once every year, but usually when its moved. Convergence operations are typically a user serviceable function and the process can be started from the menu.  If you have tried doing the user convergence and it is still a bit off you will need to get it to a repair technician that can either fix the power supply or mechanically align the guns.  In my many years of TV experience, rear projection CRT's are typically discarded for two main reasons; either the power supply is causing convergence issues or the blue gun is dull or dead. Either way if you cannot perform a convergence yourself you are looking at $200+ in repair and parts. I would suggest finding a local television repair technician, not many left I know, and get a quote.

Red color alignment problem


1) Whenever a rear projection TV has convergence issues, the
fix involves replacement of both IC's = STK392-110.......sub to
STK394-160E for improved durability...........
2) Soldering only is a temporary "fix" at best
3) Do not allow generic IC's, OEM quality or better = I use
Hitachi brand,made by Sanyo,with no callbacks....
4) Skill level needed = above average,....needs chassis pull...T.

The heads of the people are cut off the picture is to high


If the top of the picture is stretched and off the screen and the bottom appears normal, this is usually a vertical deflection problem and will need a repair tech to fix. If you continue to watch the set with this problem present it will only get worse and can cause more problems.

Letters on screen missaligned horribly, red/blue off wakko


It sounds like a convergence problem. A fairly common reason for this problem is the convergence chips have failed. They are usually referred to as "STK" chips since the model number of these chips start with STK. I will put a link to another part of this site where someone has posted pictures and a link where to get the parts should you decide to fix it yourself. Look at Ecullier2012's posting. Jean's posted site will not fix this problem. Hope this helps you out. Let me know.

You have bad conv. ic's.On these sets when the ic's go bad it will usually pop a fuse or burn up a few safety resistors,causing ith video to go away.
