Replaced the bulb in my hitachi 50v500a but screen isnt very bright and the Light engine was replaced last year.i live in az where you have to dust daily. could it be dust inside the unit? like on the mirror? and does anyone have a link with instructions as to how to remove the front screen to clean it.thanks

Sir try to check if there is a loosed connection in the light engine or cold solder in the electronic circuit board, this loosed connection cause your unit to malfunction, or the light engine of your unit is getting faulty. Good day sir and best regards.

THIS IS SO COMMON THERE ARE NOW SEVERAL CLASS ACTION LAWSUITS OVER IT---I suggest you get involved---the replacement engines are all rebuilt and supposed to "not have the same trouble".

Let me know if I can be of assistance.

GOOGLE THE MODEL NUMBER WITH CLASS ACTION LAWSUIT AFTER IT.

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.

this is a light engine problem it needs to be replaced

The problem is your light engine is failing. The part number for this is UX22201DR and is available for purchase with the following link. It runs $334 dollars and really is a part that needs to be replaced by a technician due to the complexity in tear down to remove it. Please take a few moments to rate my answer. Thanks...

You need a new light engine.

you dont reset it the ballast for the bulb took a ****.. i paid 300 for a new bulb and wasnt the problem then paid 150 for new ballast now i think the light engine went bad geeze

You have a defective light engine and you do not have to be under warranty for Hitachi to replace this part. We just went through this and here's what you need to do. Call Hitachi's customer relations department at 800-654-7013 and tell them that you have a defective light engine. They will act like they've never heard of this problem but they have. They will give you the names of some certified dealers in your area to call. Once a tech comes out and confirms that it's the light engine, call Hitachi back and they will send a brand new light engine to the dealer and Hitachi will cover the cost of the part (cost $1500).

Here is the deal, if you're under warranty, Hitachi will cover the part and the install. If you're not under warranty, all you pay is the install. Our install cost $400. Others on this site have paid $200. Do not let anyone tell you that you have to pay for the light engine part...you do not. Hitachi has not recalled this part but they are replacing it for free. Also, deal only with Hitachi customer realations number that I listed. Good Luck!

We had the same problem and just got our light engine replaced last week. Yes, Hitachi will ship the part and they will pay for the part but they will ask you to pay for the install (unless like Dev23 said, it's still under warranty). Hitachi shipped the part to the certified Hitachi dealer that they recommended. Cost to us was around $400. Worth it to us being that the TV cost $3600 when we bought it 3+ years ago and up until we had the light engine problem, the TV has been great. Since the light engine was replaced, TV looks brand new. You will read some post about this problem were people have had up to 3 light engines replaced. Back when Hitachi was made aware of this problem (about a year ago) they were sending out refurbished light engines and not new ones...obvious cost savings and cheap way out for Hitachi. The tech that came out and installed ours said that now Hitachi only sends out brand new light engines.

You should really only deal with Hitachis Customer Relations Department and not regular customer service. When you first call, they will act like they have no idea what you're talking about. After you have someone come out to look and tell you that YES, it's a light engine defect, they will ship the part to the dealer and then the tech will come out and rinstall it. The customer relations department # is 800-654-70103.

If you're willing to pay the install, they will cover the part. The part we were told cost $1500. Regardless of a warranty or not, this is a DEFECTIVE PART and I think Hitachi should pay for the entire tab none the less, we just wanted the TV fixed without a hassle! Good Luck:)
