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.

Did you replace the Lamp, if so then check your door switch to make sure works

  • Do not block rear Fan exhaust port. A minimum of a 2 inch clearance is necessary.

  • If the Fan Exhaust port is blocked, the temperature will rise in the Engine assembly and cause a thermal switch to activate, shutting off the unit.

  • After a cool down period and the set is unplugged for greater than 30 seconds, the set will return to normal operation.

  • Upgrade to New Style bottom Filter to avoid premature clogging and over heating.

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

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.

It sounds like a heat problem, i think you are going to have to call out service engineer to read the error codes.
Could be power supply or the control board.

Good luck and please comment back and RATE if this was helpful.

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.

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.

Filter warping due to over heating.

The only repair for any of these symptoms is replacing the Engine Assembly.

Prevention:

To prevent the overheating caused by clogging of the bottom filter, upgrade to the new style bottom filter. Upgrade to New Style bottom Filter
