Hitachi Ultravision 50vg825 picture dims after It has been on

The picture on my ultravision 50vg825 starts out bright, but after the tv has been on for a couple of minutes it dims. I have messed with the setting in the video menu and that doesn't help. And, yes, I have checked to make sure it isn't set to the preset night time setting :)

    Mine is a 50" rear projection LCD. Sometimes it is only on for a few minutes when it dims, I also noticed that when ther is a blank screen that it usually has a blue tinge but if the picture is dimmed it has a grey color to it.

How can i fix my hitachi ultravision it has green and double vision on top of screen


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

I'm not getting any red in my picture on my hitachi rear projection ultravision tv


A model number would help here but if it is older and uses 3 picture tubes carefully with the back off and set on does the red one come up and produce a red image?

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.

Hitachi ultravision 50V500A screen dim


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.

No picture or just one line across screen on hitachi ultravision rearproj.


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.
