Has a black screen. The screen slowly went from dark to darker, then went to dark. I have a Hitachi CLU-572TSI projection tv

Not likely a do it yourself repair---loss of the filament voltage (6.3 volts) in the power supply of the set (some had issues where a resistor changes value).

Broken screens on 53'' Hitachi rear-projection TV

I think it would likely work if you trimmed it evenly around the sides in order to maintain the central position. Focus may have to be adjusted but thats all.

Pictures very dark, Brightness all the way up. Contrast does not adjust

I have the same problem. I was able to temorarily fix the issue by taking the back cover off and blowing all of the dust out. But this only worked for two days. Now the problem is back. Did you fix the issue with your tv? Thanks.

46" Rear Projection Hitachi - Green / Yellowish Screen

daveT29 - I had my brightness cranked, too. The picture went dark and off-color after moving the TV from one corner of the living room to another.

After waiting for the TV repairman for about 4 weeks, I "fixed" it myself. Take the front panel off (4 screws, then a black panel) and blow out all the dust. I was afraid to use a swiffer duster because of the static electricity, so i just used with my mouth blowing powers.

That's it. Seriously.
