    Just want to know if replacing the bulb with an OEM bulb would fix the problem. Guess I just will have to buy one and find out.

    Thanks for the help just the same.

    the bulb that failed and was originally in the set had a reflector that was completely shiny. after bulb replacement and the problem gradually occurred I removed and inspected the bulb to find that one side, about 1/4 of the reflector was now blue. I believe that it is the cause of the blue haze problem.

    what do you think???

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

    If the unit is coming on and you have a picture no amount of bulb changing will help. If it's something wrong with the color then the problem is elsewhere. I still have no clue what your problem is...

    Not likely... The reflector in the bulb won't transmit color from a reflective surface... Have you ever seen a blue mirror - the old cut glass ones? If you shine a flashlight on iot it reflects only the white light. In order to color the light it needs to pass through some filter - in this case a color wheel.

    I still believe your problem has to do with the light engine or logics, not the bulb...

Blue blob on screen of 50V500 tv


it's not the lamp (obviously, as you found out). the light filter on the blue lcd has a burn mark on it and needs replacing. many companies don't sell parts for the optical engine (where the filter is), so you may have to purchase the whole engine, which tends to be pricey.

No. I would suspect it being a Optical Block issue. I is not a pretty repair not to mention the cost factor. If you could get in touch with Hitachi Customer Service they could lead you to s service facility that could comfirm what I think.

Hitachi 50V500, no picture ,sounds for about 15 sec.then goes off


Hello,

I would try to re-seat the lamp. Pull the lamp out, check it to see if it may have gone bad again, then put it back in to make sure the contacts are connected. Before applying power, unplug the TV for 5 minute, and then plug in/turn it on.

Most lamps, if bad from the factory, will go out within 3 months of use. It does happen, and happens more often than you would think.

Try this, and see what happens. Good luck.

It is a failure in the light engine itself. You will need to have it replaced. Here is a link to that rather costly part. http://www.partstore.com/Part/Hitachi+Ltd/Hitachi/50V500/Hitachi+Ltd/Hitachi/UX22201D/New.aspx
