Question about Toshiba 50H81 50" Rear Projection Television

1 Answer

My T.V. has a funny color .. more of double viewing with purple and green what can I do to fix this?

MyT.V. has a picture which was always properly colored. Recently,seemingly overnight, the color is primarily purple and green uniformlyover the entire screen with a double view of people and words on screen
What is the problem?

and i dont know what degaussing is
When I'm in convergence mode the red cross seems to reach maximum movement and still doesn't quite allign with the blue and green. This causes color separation in the top right and bottom left of the screen.

Your set has a problem with its convergence circuitry. In many cases this can be simply failure of solder connections to the output integrated circuits due to the heat they generate, and resoldering them fixes the trouble. This is a repair you might be able to try for yourself if you have experience with electronic soldering. Or there might be component failure which would require the equipment to isolate and replace the bad parts, which is a repair level best left to professionals. In some cases where the set has digital convergence, the failure might be in the computer control portion. This means the repair might range from only a very few dollars in parts to quite a lot of dollars, plus whatever labor rate the servicer charges. If you aren't looking for an excuse to replace the set, getting an estimate on a professional repair would be the best suggestion.

Degaussing is deliberately applying a magnetic field to the face of a picture tube. This is done to neutralize the effect of other magnetic fields that can cause color distortion. Degaussing isn't done in projection sets because they have separate tubes for each color.

Degaussing means to demagnify. Not applicable with a projection tv. You have a severe convergence problem. Either a component failure, a speaker or other powerful magnet in very close proximity or someone figured out how to adjust (or misadjust) it.

The picture has colored shadows and doubled images. People are doubled shadows are red green purple. I would like to know if it worth fixing the tv is about Ten years old. Thank You


In a nutshell, the convergence ICs have failed. The cost to fix by a service company is likely about $300. You may find someone who does it on the side for around $150.

If you are happy with the picture, you like the tv, then $150 might be worth it.

It is possible to do this repair yourself if you have an electronics background.

What kind of connections are you using?

If component (red, green, blue) double check to make sure they are seated properly. I'm thinking it sounds like the blue one got loose.

Screen is bowed (top and bottom) Color has a green and purple tint?


Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

Purple lcd display


Hello tonyj111, If your old pictures look fine on the display, then the problem is related to the ccd sensor itself. The purple color is displayed because of a problem in the signal transmision from the ccd sensor to the camera's main processor. This is done using 3 channels one for each primary color (RGB red green blue). If the connector to the sensor is broken, or got out of place (loose) because some mechanic shock or symilar, the data processing woun't come out right. It is purple because your camera's processor mess up blue and red signals therefore resulting same purple instead of blue or red colours. In order to fix this you will need to either send the camera to a service center to have those connections checked (if your camera is still in warranty you will want to do this) or ask me for further instructions if you wish to try to dissasemble the camera yourself. In either way the problem is fixable and in most probabilities a cheap fix will work. Good luck
