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.

Started with small blue dots to left of screen. mGrew to a dark blue blob in the center of the screen. How can I fix this.


The light engine (the projector part of tv) is failing. A common problem, but very expensive as you have to replace the entire engine, can't be repaired. Check with Sony to see if this model is still under their extended warranty or not. If so they'll fix it for free, if not be prepared to pay several hundred dollars at the least. At that point you'd probably be better off buying a new TV.

My Hitachi LCD rear projection TV has blue color in left corner


It is most likely the tube going out. Find some one to replace the tube if the TV is fairly new other wise it is going to be a trend. One tube now and another.. and so on. Ride it out as long as you can then go for an upgrade
