    My picture is very grainy. I do not have problems with red dots or blotches on the screen, just a very grainy almost snowy picture. I have had to reset the ghost twice lately as well.

Clean the lenses. This involves taking off the screen, which often involves removing every front panel on the set from the bottom up. Have somewhere to rest your screen, like an ottoman.

Hitachi 50v500 lcd rear projection just trying to get the setup so cable works on ant a can't make the channel move when im on ant a set up.


be aware this model has almost a 100% failure rate on the light engine which while not related to this issue should be kept in mind.

If you have cable get a box with a/v jacks on the back and hook to a rear input on the set--bypass the whole issue and get a better picture.


PS: I don't think it is the set itself causing this ........

Foggy picture quality, white too bright


Hello,
This indicates an Automatic Gain Control (AGC) problem often caused by a dried up capacitor. You will probably need a schematic to go much further. This could be a problem in the tuner, IF, or video amplifiers.

The following assumes you are sure the signal source is strong - try a VCR or other local one (channel 3/4, not the RCA jacks).

(From: Glenn Watkins (blueribb@mail.comcat.com).) Substitute a variable voltage source for the tuner's AGC voltage. Most of the time the range of AGC is from 1 to 7 volts. If you can get a decent snow free picture with an external AGC source, then the tuner is probably OK.

This is will require you to open the back cover of the television alongside an ohmmeter to read components on the printed circuit board of the television..
Take care

Can i optimize my grainy picture on my Hitachi projection tv


Unfortunately, without me seeing it I can't tell all what you will need to put it back into optimum performance. Older projection sets are pron-ed to having the coolant replaced for the 3 picture tubes. I don't know the quality of the tubes themselves, so it's really tough to make a call on your set. If it's just fluid, I would say you would invest $300.-400. in work. I don't believe it's worth putting that much into it if that's what it needs. Of coarse this is only if you have a projection set, you didn't state what model of set so I'm assuming it is one. Hope this helps......

id guess your set is like a 50v500 or 50v720 its a lcd rear projection
the blue cloud come from a warped lcd plate in the optic engine and would require replacment to correct this problem
if you have a extended warranty you would want to contact them
if not you might contact hitachi consumer affairs and ask them if there would be any assistance with this repair
