I have a 55in hitachi i purchased a little over a year ago, and sure enough, right when the year warranty ran out, i started noticing that images were beginning to burn into the screen. after a while, i noticed that the spot that images were burning on, now have a blue spot growing larger as i use my television. i guess my question is, is there a quick fix, or do i need to just buy a new tv. i don't wanna spend too much money fixing it when i can just go and buy a new tv.

I have been told by a local repair person that Hitachi might replace the light engine at no cost because it is such a big issue... has anyone hear about this... I am going to contact them directly also.
I would first try a new lamp. If the reflector portion of the lamp has any defects, it could show up this way as the light would not be uniform. The next possibility is a defective light engine. The engine portion if not field repairable and would need to be replaced. Try the lamp first and let us know what happens.
Do you normally leave this set on a specific channel...such as CNBC or BLOOMBERG tv...etc that maintains a regular scrolling image???
If so...on sets that are a few/several years old...the projection tv screens can develop what's called a "burn" or "burned image" on the screen...similar to wearing a path in your carpet from heavy traffic areas. Newer models do not have this issues...but many older ones do.
I have the same problem with blue haze that just spread out on model 55VS69A ,
tv is almost 2 years old. i called hitachi and they advised to call a local repair center to check the tv...they confirmed Optical Block (light engine ) replacement light engine cost $1400 and labour $400, so i called back hitachi and they said they will provide light engine and will have to pay labour!....this is not right paying out of pocket for a tv less than 2 years old....I am not sure if the issue will resurface again...more likely ....Hitachi is supposed to issue a recall or atleast like sony did to cover all cost for there defective TV's....I will NEVER buy hitach again.
Sounds like the TV's convergence circuit has failed: *Call an Authorized Service Center and them give you an estimate cost of the repair, or *Repair it your self; get KIT 10 locally or B&D Enterprises 1-800-458-6053; www.bdent.com. Good luck, big IRISH.
I had the same problem on my Hitachi rear projection TV 53FDX20B made in Mexico. The blue convergence problem. Blue focus had shifted and appeared like a blue ghost image. I followed the step by step intructions from the fixya site. First Replaced the two STK 392-110 ICs and turned on the tv. No change. Then I went looking for the bad resistor. There was one resistor RK50 (2.7 ohm, 1Watt capacity) which is attached not right close to the printed circuit board surface but was well raised up from the board. The bands on the resistor were a little discolored. I replaced that one and turned on the tv. The convergence problem was solved. Thanks for the step by step instrucitons on your site.
