Hi! my tv hitachi 50v500a ultravision had problem the screen of the tv have big red cloud

To change the lamp on your Hitachi 50V500A Digital Ultravision TV, please follow these steps:

1. Turn off the TV and unplug it from the power source.
2. Locate the lamp cover on the back of the TV. It is a small plastic cover held in place by a screw.
3. Use a screwdriver to remove the screw and take off the lamp cover.
4. Locate the lamp cartridge and pull the handle to remove it from the TV.
5. Unscrew the lamp cartridge and remove the old lamp.
6. Insert the new lamp into the cartridge and screw it back in place.
7. Reinsert the lamp cartridge into the TV and push it all the way in until the handle clicks into place.
8. Replace the lamp cover and screw it back in place.
9. Plug the TV back in and turn it on. Check to make sure the new lamp is working properly.

It is recommended to refer to the user manual or seek professional help if you are not comfortable doing this yourself.

The model indicated is a DLP rear projection and uses a "lamp" for brightness.

If it has not been changed for a while it should be on the right side of the set behind a removable plate. Check your owners manual if you have it.

Life span varies but 2,000 hours is normal.

Let me know if you need any further assistance as I am here to help.

go to the menu screen and select picture mode/menu and you should see the option to make changes to colors selection. You can also try and find one of your DVD's that has THX listed on the case. These DVD's have a calibration program included in the disc which can assist you with fixing the color issue

Hi Winston,
Check this website to see if you can find the user's guide. If you have the 55VG825 model, the user's guide is available.

I have a 60 inch lcd with the red cloud, bought the tv in 04 called hitachi about it and there sending my tv repair man the light engine no cost. Everyone just needs to call them again. thanks Jim

Good Day, imfamous44;

This is common for the HIT LCD projection. In most cases, I've seen, the manufacture will cover the cost of the "light engine", but you will have to call them and express your concern. 90% of the time they will cover this, be nice but firm.

Good Luck, big IRISH.

if the lamp has dies alot of the time to can look inside the lamp and see if it exploded (not always) do you get blinking lights?

A BIG RED SPOT APPEARS ON THE SCREEN WHEN U TURN IT ON WHEN IT IS STILL BLACK. THEN ARED HAZE IS VISABLE IN ABOUT I 6 INCH AREA WHEN VIEWING THE TV.
