Replaced lamp in 55vg825 approx 1500hrs ago & lately the picture has lost brightness compared to when the new bulb was installed. Is there another adjustment or is the bulb defective already? Past...


You are correct about lamps working or not, but that is the extremes. Over the course of operation all lamps lose brightness as the hours add up. All lamps will lose their brightness over time.

Typically lamps only last at best 6000 to 8000 hours. That is not long if the unit is used most of the day everyday. In addition the cheaper the quality of the lamp, cost and manufacture, the quicker they go down hill.

Assuming that you have a low quality lamp what you are experiencing is normal. You may be able to improve the brightness and clarity of the picture by cleaning the lenses, mirrors and screen. I have a tip at

This tip is labeled projection tv but is also appropriate for cleaning an LCD or DLP unit.

Thanks for using FixYa and for the great rating.

My tv has a yellow, green or blue tint to it. We think it needs a new picture tube. Do you think that is the problem and if so is it easy to do myself


You have Light Engine Failure. Only fix is replace the Engine. Here is a Page that shows Hitachi LCD Projection TV Optical Engine Faults.

Check for these faults before spending money on a failed bulb. Here is page with all Hitachi TV Lamps and Bulbs.

My Hitachi Ultravision also makes the buzzing noise and the flashing red lights. I know it isn't the picture tube because it does this sometimes and then other times, it just powers up and works fine....

From what I'm gathering on a search I found that this is an LCD rear screen projection TV. The issue you may be having is a problem with the lamp or the lamp Ballast. If you are able to remove the lamp and check it, my thought is that it has imploded. You may just need a new lamp.

Good Day, mmurray1959;
To me it sounds like you to replace the lamp if you want to view your TV in the future. Good Luck, big IRISH. PS most lamps last about 5,000 hours.

Refer to owners manual ! Blinking indicates the type of fault that is occuring on all your tv sets. example : power light on red - indicator light beside it green but blinks rapidly for half a second rapidly then shuts off. This refers to a faulty lamp or a lamp that is near its expiration. Read your manuals if indicators refer to easy repair sweet, but if it says call tech then bummer...
