Question about Akai PT4298HD Rear Projection Television

Akai PT4298HD displays yellow tint in lower left

I have a Akai PT4298HD that is a few years old. Recently it is starting to show a yellow tint (on a light colored background or blue haze on a dark background) in the left section of the screen where the mute is displayed on the screen when the tv is muted.

If this was a CRT I would have thought it was a burn in area on the screen. I didn't think this could happen with a rear projection tv? Any way to figure out what is causing it or how to fix it?

Thanks

OK YOU CANT 'BURN' A REAR PROJECTION BUT THE CONVERGANCE CAN BE GOING OUT BUT I WOULD GUESS THE SIGNAL TELLING THE PROCESSOR - OR THE PROCESSOR ITS SELF- IS PROBLY GOING OUT WHICH MEANS A BOARD NEEDS REPLACING I DONT KNOW WHICH ONE I WOULD GET A PRO TO CHECK IT AND TELL YOU WHICH ONE IT IS THEN ORDER IT ONLINE AND REPLACE IT YOURSELF

Uh, your tv *is* a CRT set. A rear-projection CRT set. But this isn't burn-in. It's either a dirty lens or some mold growing in the coolant. Better pray it's a dirty lens, otherwise you may as well just replace the set because the repair could be quite costly.

Lenses ought to be cleaned once a year.

If you have a good picture except for a missing color all the various circuits are working OK. Most likely you have a bad solder joint or component in the red circuit. This would also be indicated by the fact that ocassionaly the red pops in. If you have the experience remove the boards and inspect for cracked or cold solder joints. Resolder anything that looks suspicious. If this does not fix it you will have to troubleshoot the red drive circuits from the CRT back to the video IC. Another possibility is that you have a bad/intermitant red crt. I doubt that you have the equipment to check this but you can test it by moving the green crt board to the red crt. If it now works the red crt is OK. If all this fails you will need to find a reputable repair shop to look at it. If the unit is more than 5 years old it may not be worth fixing. Good luck.
