TV rca hd 52w59 has convex picture. can I fix it.


If convergence adjustment did not correct the problem likely the convergence IC's have failed and will need to be replaced along with a few defective resistors in that circuit. If you have never attempted TV repair this would not be a good repair to start on.

The only way to be positive of the problem is to have the circuitry diagnosed by someone with the proper TV test EQUIPMENT to determine what parts that are no longer within specs.

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.

PICTURE


By the picture that you have supplied with the question you have a rear projection tv. The problem you are describing sounds like you have had the convergence module in your tv fail. Depending on the age and make of the tv, the repair costs ( if out of warranty ) can be prohibitive. The convergence module on rear projection tv's not only is in charge of bringing the 3 different color images together into a watchable picture but also handles the east west correction ( concave / convex aspect to the picture or lack there of ).
