Same problem I have had my Hitachi LCD unit for over 2years. I am beginning to notice the gradual presence of a red spot growing and becoming visible on the screen. It is more noticeable when the picture light level and content is low. When the picture has alot of color and light content the problem is not as apparent. So what is behind this gradual degradation?

Hi, you have an Optical Engine fault. Complete assembly needs to be replaced. This page shows the most common Hitachi Optical Engine Faults.
Hitachi LCD TV Light Engine Optical Block Info

Remove off the battery use a hair dryer to warm off carefully the display not get it hot but just see if this is any moisture build up.
replace battery and check for any change , is so repeat softly in short time.
If not the display unit can be getting bad as the LCD might have failure within the matrix.

I have hitachi lcd rear projection tv model 60v500A at first I was getting a red spot on centar of tv with in two mounths the spot got bigger. I chanched the lamp but now i don't have a picture, the red indicator on tv is now blinking.

Your light engine is going bad.

Hi,
1) That red spot means that a pixel is stuck, actually it's very common on LCDs.
2 and 3) It usually occurs for a manufacturing issue.
4) The most of the time it doesn't mean that the whole screen is going to fail, but in my case I would take advantage of the warranty if the laptop is brand new and the warranty is still there.
Good Luck!!!

Deb,
Unfortunately if you're not a technician Hitachi won't even consider sending you a LE for install... They will confirm your status and have you fill-out several documents.
As to the other part of the question, the service manual won't help - there is a procedure for memory re-initializing and after performing that you still have the spot then LE is called for.. But again, unless you're a tech with those letters behind your name Hitachi won't accept the results.
That said, we have done several of these and Hitachi has been exceptional to deal with pre and post install.
Hope this helps!

We took in a 60v500a with the same problem, Customer bought a new set. We took hers apart. Here is what we found.
1 there is a squril cage blower and a small air duct that cools the lcd screens and polarizer lenses. Yes there are 3 polarizer lenses one in front of each LCD screen.

These start to overheat and discolor. Maybe the filter for the fan clogs up.

Don't really know.

You can pull the LE and vaccum the filter clean every 3-6 month.

You can remove the lenses and maybe the tv will look ok maybe not. I have read where some have had there repaired and now they see vertical lines in the screen. This seems to be a quike fix by removing the melted lens. Cool A.

We had the same problem and the infamous "red cloud" is a light engine defect and Hitachi knows about it. After calling Hitachis Customer Relations Department (not customer service) they referred us to a local Hitachi dealer that diagnosed the problem in less than a minute as a "light engine defect". We called Hitachi back and once they confirmed this with the dealer, they shipped the part to the dealer and the tech came out and installed it...looks like brand new TV. Here's the deal though, when you first call Hitachi, they will act like they've never heard of the problem until you have theTV looked at. They will pay for the part...$1500 but they will ask you to pay the install. Our install was $400...worth it to us on a $3600 TV. Be sure and call the Hitachi customer relations department and not regular customer service...you will get no where with them. The Customer Relations Department # is 800-654-7013. Good Luck!

I suggest you send it back to repair shop to clean ccd area. there are fine dusts in ccd screen area that camera need to be disassemble and removed and cleaned. I do not think the LCD is the problem. Some point and shoot models dust flowing through more than some others and if I am not mistaken, it seems this model has dust problem.
