Hitachi ultravision 50V500A screen dim

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.

Likely the lamp in the set has failed here which does make sense if the picture was dim before---a lot of lamps just before failing all the way dim down.

There is no solution - eventually the entire picture will turn blue. It's out of warranty and replacement of the light engine is way too expensive. Start shopping for another tv - I did

Check your closed-captioning setting and make sure captioning is turned off (or set for captions if you really want them). You'll find it's set to "text" mode right now. The set is blanking out a portion of the screen to display text it never receives, and you'll only see this when you view a channel where captions are being broadcast. Most sets have a button on the remote for captions, and it's easy to switch modes without knowing it. Then you wind up with the mysterious black box.

If this helps you out, please take a moment to rate the solution. Thanks for asking here!

I had a similar problem with the same projector. Replacing the computer to projector solved it.

convergance chips bad or dead /weak capacitor or resistor on neak board . im repairing now. repairtech

Could be a loose connection on the printed circuit board in the Vertical deflection circuit.
You would have to have a qualified technician to repair this problem.
A intermittent connection in the circuit described can cause a horizonal line across the screen.
You have to be careful and not leave the TV on for a period of time with a bright line, as it can actually burn a line on the CRT screens, which is permanent.

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?

How many led lights are showing in back of set/ Hitachi, has a way of telling what is wrong by the numbers and sequence the lights give off. Most of the time it's the convergence going bad. You should have seen some colour distortion before set wet out.
