It is most likly an optical problem with dust or a haze on the optics or a bulb problem or could be a bad LCD display.  If I were you and if you are handy, get a service manual, look at how to disassemble the optics and light housing, and clean everything first, but NEVER ever spray anything onto the optics and use just a slightly damped soft cloth, never any paper product.  Or the way the pros recommend is with compressed air, but if it is canned air, be carefull, as those things get cold and you can easaly damage something.  In a good camera store they will have a bulb type blower to clean lenses off .  Let us know how you made out. Good Luck

Both of your problems are due to a bad optical engine. Hitachi has extended the warranty of the engines out to 3 years.  You'll need to contact an authorized Hitachi service center to have this fixed at no charge. 

MOtvGuy-

Thanks for the update,  I was beginning to think there was only a "tunnel at the end of the light"!!

I'll call my local authorized service center tomorrow. 

You're lucky, some others are running into resistance from Hitachi.

BTW, I checked with my work and only the V500 sets that we bought are covered by the 3 year warranty. Everyone else is stuck with the standard one year.

From what I have been able to read while searching the web is that it sounds like the
