    I also have this problem - and I remember there used to be a place in the menu where you could change the "Convergence" so the colors are all aligned, but I have looked through all the menus and can't find it anywhere! Any help?

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 ).

My tv screen when on turns yellow then after a while it will switch back to normal colors what can be wrong with it....


Televisions covered: all Projection with yellow picture, but not Projection TVs with a yellowish tint surrounding objects in a nearly normal picture.

Yellow = red + green
normal picture = red + blue + green (RGB). See illustration.

Fig. 1 Additive color mixing in an RGB monitor, or RGB Projection TV.

The circuitry powering your blue output, or the blue light engine itself is starting to fail.

Operating Theory:

The lamp module shines a bright light into the optical unit; there are a series of lens and baffles, and at the top of the light engine, a lens puts the picture into a mirror which is reflected onto the screen; All video and color is processed thru the light engine. Blue most commonly fails first, leaving a yellow picture.

My RCA projection TV - the picture only shows red green and yellow and the picture is distorted almost concaved. It overlaps and nothing is clear. All 3 bulbs seem to be working. No idea what is wrong.


Sounds like convergence problems. This TV may not have the standard "STK.." modules. These sets are bad to lose voltage feeding the convergence amplifiers.

The colors are distorted and it seems like the only colors that really show are blue, green, and red. When you turn the TV on you can see blue, green, and red lines across the screen. The picture also...


Hi there, this is what we call in the industry convergence board failure. this board regulate the rgb and keeps everything in order so the picture looks nice and clean. when this board starts to malfunction, what you are witnessing is usually the result. I suggest repairing this convergence board. this will fix the 3-d effect.

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 is yellow and green


Your missing the red drive on the set. Its most likly the picture tube. Its a possibility that the red drive circuit could be not working so the best thing to do is take off the gree picture tube socket and put the green board on the red tube. Of course do all this when the set is unplugged. if you have no tv experience. its not a good idea to be messing around inside of these sets.
