Hitachi 50V500 50 in. HD-Ready LCD Television - Page 8 Questions & Answers
Hitachi LCD HGTV has lot color. Replaced lamp.
If has lost color on more than one source( just to verify it's not a bad cable or hook up) it's probably a broken color wheel. You can usually see the color wheel when you remove the lamp. There should be a glass looking disc right where the lamp would shine, the wheel will have segments with different colors.
My Hitachi tv no longer has any green contract
Hello,
This problem is very common with rear projection TV's.
It
is related to one or more of the colour guns being out of alignment or needing to be replaced.
The only way to correct this issue is to have a technician come in and
fix it or bring it into a repair center. I personally would suggest
purchasing a new TV. The cost of getting them aligned is usually more
then a basic LCD.
Hope this helps

I see a big blue spot around center screen
That model is a rear projection and the blue spot indicates failure of the LCD panel in the blue path on the optical block of the
light engine. You can't buy the LCD panel only, and if you could you
would not have access to the equipment needed to align and position it
in just the right place, ie perform mechanical convergence... I'd say the unit probably not worth fixing.
Hitachi 50V500 has a blue blob in the center of
That is a burnt LCD panel caused by excessive heat from the lamp, maybe due to blocked/restricted airways.
It is not likely to get any better and a new LCD unit will be required to repair it along with new filters and maybe a fan.
I have bought the biggest lemon in this tv than
Lamps have a limited life. They useually last 1000 hours or so. If the TV is on from 07:00 until say 23:00 every day, that equates to 60 days.
There is no such lamp as a "One time replacement lamp" as they do not last for ever.
The average life of a lamp is just about 6 months.
If the picture is cloudy is probably needs the optice cleaning. It is very fiddly and damage can occur easily so get an authorised Hitachi repair service department to clean it for you. It should be carried out in your home and will take less than an hour. If anything gets broken, it is not your problem if they are heavy handed.
Hope that helps.
