Blue Blob in center of screen

I have a 2 year old 50" LCD Hitachi that was working fine up until 1 month ago. Now I have this big blue blob in the center of the screen that seems to be getting bigger and bigger. I am not happy with this piece of junk at all, all will never, ever buy HITACHI again. In the mean time to save face with my wife after spending near $3000, how do I fix it? Please help

Re: Blue Blob in center of screen

Here is what you need to do...just went through this. Call the Hitachi customer relations department at 800-654-7013. Tell them what the TV is doing and that you have a defective light engine. They will act like they have no idea what you're talking about but will give you some names to some certified dealers in your area. Have a tech come out and once they diagnois the problem, call the customer relations department with Hitachi back and all of a sudden, they will be aware of the problem and will call the dealer directly to confirm that it's the light engine. Once they confirm it with the dealer, they will send a new light engine directly to the dealer at their expense (part cost them around $1500). The dealer will call you to set up a date/time to come out and install it. Our install was $400..worth it to us because we paid $3600 for the 60" set 3 years ago. Once our light engine was replaced,the TV is like brand new.

Please deal only with Hitachi's customer realtions department at the number listed above. Their regular customer service will have you chasing your tail. Also, DO NOT let any dealer tell you that you have to pay for this part once it comes in. Hitachi is replacing it for free..all you pay in for the install. Good Luck!

Blue blob on screen starting at lower left and creeping up onto center of screen. Longer the TV is on, worse the blob gets.

It is most likly an optical problem with dust or a haze onthe optics or a bulb problem or could be a bad LCD display. If I were youand if you are handy, get a service manual, look at how to disassemble theoptics and light housing, and clean everything first, but NEVER ever sprayanything onto the optics and use just a slightly damped soft cloth, never anypaper product. Or the way the pros recommend is with compressed air, butif it is canned air, be careful, as those things get cold and you can easilydamage something. In a good camera storethey will have a bulb type blower to clean lenses off .

If your problem is with the light engine Hitachi has extended the warranty of theengines out to 3 years. You'll need to contact an authorized Hitachi service center tohave this fixed at no charge.

Hitachi 50V500 has a blue blob in the center of the screen that is getting bigger.

That is a burnt LCD panel caused by excessive heat from the lamp, maybe due to blocked/restricted airways.
It is not likely to get any better and a new LCD unit will be required to repair it along with new filters and maybe a fan.

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.

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.

Blue Haze in middle of screen vertical

There is no solution with Hitachi products.

If you have read many of the posts, you would have known not to buy Hitachi Telivisions or like me avoid all Hitachi products. There help line is not very useful, they just blow you off. I have never had a worse experience with other manufacturers. Take Onkyo for instance, they had a problem with a chip in their THX receiver and it was a year later ... I called their help line they located a repair store about 40 miles from where I live (in Texas that is not very long) and got my receiver fixed and this was 8 years ago.

Also use Consumer Reports to check the frequency of repair record for the product you are going to buy. In Plasma - Panasonic is a safe brand, in LCD's Sony or Samsung have good repair records.

Research the product before you buy it, avoid walking into a store have the salesperson direct you to a product. And then you save money if you order it online. Amazon online is very good.

DIY light engine

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

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.
