Re: 50v500 Hitachi LCD

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 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!

I have a ultravision 50v500 and it has a blue blob in the middle of screen. I have just changed the bulb with hardly any change in the blob. I also had the light engine changed approx 2 years ago.

That is caused by excess heat possibly due to poor air circulation/blocked filters.
It is damage to the LCD panels. It won't get any better, just worse.
So look for another Blue LCD panel and someone who is experienced to fit it.

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.

If you have the "red" blob in the center of the screen or you have "blue" blobs that show up in random areas of the picture then the only repair is to have a technician replace the optical light engine.

To all that are experiencing the blue blob. This is result of poor maintenance. Projectors must be kept clean on all air intakes. This is to help you all understand the failure cause. Usally not worth repairing.
