Check for any cracked solder on the middle power board of the chassis on the convergence ICs located on the large heatsink. make sure that you dont let this fail go on for too long becasue it will cause some fuses to go bad.

The colors are separated. Images are blurry and


Try adjusting the convergence. If it won't move see below- (or hitting Magic Focus for some Hitachi’s)
This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$400 Be sure to vote/rate me if this helped Thanks!

Philips Projection TV the colors are separated- not converging


This was hapening to me too. To fix I just punched the tv. If this works then some wires were disconnected. Punch the right and left side not the screen or the back it will damage!

Colors are separated on the top from the left to right


Probably the color convergence is off. I had a similar problem. Have you tried the magic focus button yet? That is located at left in the small front control panel. Power on TV, wait 20 min (according to user guide), then press the magic focus. If that doesn't fix the problem, you could try the service mode alignment procedure. But that's a little trickier. I don't have a link handy for that procedure right now, but will look for it if magic focus doesn't re-align your color convergence.

TN55X81 Rear Projection color separation - convergence problem


You shouldn't need to do a board replacement, all you should need to do is manually tune the convergence.

You can do this with the built-in user tool, but there's also a far more powerful set of options in the service mode. To save you the trouble (I advise doing a LOT of reading before attempting any of this) here's a solid set of various tutorials based on what form of "separation" you have occurring:

Warped Picture, Separated colors


Each color (red,green & blue) has an amplifier IC (STK-).
When there is a convergence issue,the first step is change both
IC's for reliability. Then check for open fuses devices,usually
pico fuses.Then re-check convergence alignment.......T.
