Sounds like you have some bad convergence IC's not allowing the colors to line up properly.

55 inch mitsubishi rear projection tv red lamp out of adjustment


Have convergence IC's replaced. I believe this unit uses STK-392-570 convergence IC's Only one has gone bad but replace them both, because if one has failed then the other is not far behind, for Blue and Green. One handles Red, One handles BLUE and Grn. There are only two of them in the set, They are the two largest IC's in the entire set.

RCA 52 in HDTV red, green and blue colors not alligned - concave


That repair only repairs the issue of the convergence option missing from the on screen menu. If thats what your problem is then the ITC222A convergence option missing repair kit at the following link should repair the issue. The kit contains the fl231, DL231, CL230 and the CD with detailed instructions.

Picture in concave on all sides and blue and red are off


The shape of the picture indicates that the convergence circuit is not working properly. Generally speaking this occurs without making any sound at all. The popping you heard may have been a capacitor in the power supply. If the power line effected supplied the convergence circuit, repairing the supply should return the set to normal. If not, then the convergence ICs may be faulty. If you can solder, and are confortable working inside the set where potentially dangerous high voltages exist (even when unplugged), you may be able to repeir this yourself.

Let me know and I'll provide additional details and instructions.

Screen lookes like colores separating


This is what is known as convergence. a projection tube ussally has three picture tubes.. red green blue. they all have to align. the concave picture indicates complete loss of convergence or convegence power supply. First question on these sets Do you have the convergence option in the customer menu under setup. if you do not this is a indication of the common "FL231 fuse problem" and inexpensive simple repair. I have wrote and artilcle on this under my tips and trick section. If you do have the option then next does autoconvergence work. in you case i would not think it work. under blue and red manual convergence does the crosshairs move. if not then this is indication of convergence power supply board. if they move at all this may indicate a convergence amplifer problem.

Covergence problem


your set has indications of several problems. red green and blue. indcate convegence issue. the fact that the picture is concave is a indication of totall loss of covergence power supply. the convegence menu missing idicate loss of some voltages from what know as the flyback.AND SHUTDOWN. indicate further problems. generally when convergence fails ..not always the set wont shut down. it could be a simple issue but further trobleshooting would have to occur to narrow it down.
