Question about Hitachi 50V500 50 in. HD-Ready LCD Television

3 Answers

Hitachi 50v500 I have a blue blob on the top through the middle, and a red blob in the middle. I have recently changed the bulb, and also had the ballast changed. Very expensive. Is there anything I can do without having to pay out more technician fees?

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.

Re: Hitachi 50v500

The blue blob is most likely a problem consistent with a light engine failure. i should know since i am on my 50V500's 3rd light engine. i hope you have a warranty because it's close to a $1000 repair. ...oh, and i had the same blue blob at one point and it would not go away until the light engine was replaced.

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.

Hitachi rear projection LCD with yellow blobs on screen

I have the same tv and the same problem, but my yellow is a cloud around the outside of the screen. My tv was recently moved, and a repair shop told me that sometimes in a move these tvs light engine takes a shock and causes a yellow "band" on the screen. I am hearing that these light engines are not cheap either. Hope this helps you.

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.
