Re: dimming picture

Sound like the lamps are ageing or the lamp PSU is playing up.

Mitsubishi TV 65 inch rear projection. WS 65809 I went thru the convergence ic chip replacement years ago. Love the TV. My problem now is that the brightness goes from full bright to full dim then...

The old Mitsubishi units had a super capacitor in the logic circuit instead of a backup battery. This capacitor became leaky over time, causing the problem you describe among others. Number one symptom is set has audio and dark or black picture when powered up. As the super cap charges to full voltage, picture comes and goes.

We have a Mitsubishi VS-50VA2 projection tv. The picture is very dim and the color is faded. Even after adjusting the brightness to the max, it is still dim. What do I need to do to fix this?

you need to clean the dust off lamps and the guns, if you don't know how. i can walk you thru it. but i would suggest having a repair shop do a full cleaning.

Tv brightness/vibrant

Most of the projection lamps are recommended to be replaced after 2 years. The older they get the more dim they will become. I would suggest replacing the lamp again. Some of the aftermarket lamps do not work as well as the factory replacement. I always spend the extra money and get one from Samsung.

Replacement lamp not bright

as i previously posted, my picture was dim, muddy looking after replacing lamp with osram lamp. i fixed mine by taking the screen off and cleaning the small mirror. it had a thick layer of dust on it, cleaned with a microfiber cloth. no water, no glass cleaners. i also used a very fine new small paint brush and dusted the projector lens which also had a dust film. brightness, contrast and clarity returned!

Picture dimming and an ominous clicking sound

If this set is really only 5 weeks old, place a warranty service request for repair. This should not be happening. Either the ballast is bad or the lamp. In any case, either should be covered under warranty.

Please keep us updated.

Picture (video) jumps from bright to dim

I figured it out myself. R243 was intermittently open. Replaced it, and now we can watch the Super Bowl.

Picture problem

I have an older Mitsibutishi 52" HD 1080. I recently upgraded my cable box to DirecTV HDTV. When I change to format to view in 1080 the TV goes from full screen to what seems to be wide screen with a black bar on the top and bottom. If I change the format to 480p I get a full screen; but the picture has a "redish tint" over it as if looking through sunglasses...I tried everything in my TV manual even call the cable company. Any suggestions?

Problems with brightness on the hitachi 50v810

Yes, they dim as they age, and you've done well to get 3 years out of one.
Projection TV makers charge an arm and a leg for their replacement lamps. They make it easy to do but as a result the custom lamp assy is expensive. The trick is to just buy the bulb for your model TV from any number of us aftermarket sources at a fraction of the lamp price and install it in the old lamp yourself. really easy.
