You have a defective light engine and you DO NOT have to be under warranty to have it replaced. Here's what you need to do...we just went through this. You need to call Hitachi's Customer Relations Department (not regular customer service). The customer relations # for Hitachi is 800-654-7013. Tell them what's happening with your set and that you think it's a bad light engine. When you call them, they will initially act like they have not heard of this problem but will give you some names of some certified Hitachi dealers in your area.

Call one of the dealers and they will send a tech out to diagnois the problem. Once the tech tells you that you have a defective light engine (all they have to do is look at the set when you have it turned on) call Hitachi customer relations back and tell them you had a tech out to confirm the problem. They will then act like they know exactly what you're talking about...imagine that! They will call the dealer that came out and once they confirm this with them, they will send a new light engine to the dealer. The dealer will then call you and arrange a time to come out and install it.

This part is paid for by Hitachi, regardless if you're under warranty or not. If your under warranty, the service should be covered if not, the part will be covered by Hitachi and all you pay is for the install. Our install was $400. DO NOT let any dealer get the part and tell you that you have to pay the $1500 for it. Hitachi knows about this problem and they are paying for the part. All you pay is for the install. Again, deal only with customer relations at the number listed above and only deal with a dealer Hitachi refers you to. Good Luck!

It could be only dust building up and it needs a good cleaning or it could be the DMD board is going bad and needs to be replaced.

Hi--Bought my panasonic pt-52lcx65 on sale for $2200 in 8/05. Replaced the lamp for about $300 in 1/08, just prior to Superbowl. Admittedly, this was to be expected after family members watched lots of tv over 30 months. However, two months later the blue spot emerged in 3/08, and red spot emerged 5/08. Set looks decorated by a Andy Warhol or Van Gogh wannabe. I'm looking for a fix it solution. Dr. Bob Heiliger, Lebanon, OH.

Is it a fuzzy spot or an actual hard edged black spot?LCD televisions can have a loss of pixel display- most very small. Was the TV hit with something or dropped against something (the screen)?

OR Try this first:
Black box appears on the screen
• Closed-captioning might be on. Check the Analog or Digital Caption option in the Setup menu.

Please let me know if your problem is solved. Thank You.

You really need to be persistent. I went on the Panasonic customer support webseite and started a web exchange. The first two attempts ended with "call your local authorized service tech" , etc. The third time, I described the prolem again and asked if the authorized tech would have the tool to fix the eprom if that was the cause of the problem. They finally gave me a name for their scheduling department and said they would pay for the diagnosis. I was pretty happy about that, but even happier when they said that this was a known problem and they would pay for the repair as well. They scheduled a service call. The techs came and fixed the eprom error with their tool within 1/2 hour. That was about 5 weeks ago, and all looks good so far.
