Hello rivas_gab. Before I answeryour question let me explain a little how your tv works. You TV uses is a 3LCDtv that gets its picture from a lamp, the lamp produces a white light brighterthan the sun, the light goes through a square prism and is split 3 ways, eachgoing through a small LCD chip (blue, red & green). Then it travels troughthe light engine where the final picture is produced. The blue blobthat appears on the screen might be caused by one or two lcd chips that havestarted to get burn by the intense heat emitted from the light of the lamp. If that is theproblem you’ll have to replace the entire light engine, the other option isthat you buy the prism with the lcd chips, how ever that almost impossible becausenobody that I know sells them separately. If you decide tobuy, search buy part number, NOT model number, otherwise you’ll run the risk ofgetting non compatible parts. If you’re lookinga place to purchase look for dedicated tv part distributors (my personal recommendation:Discount-Merchant ). Happyhunting.

62.in hitachi projection t.v. has yellow oval shape in center of screen dark blue color on rest of screen picture fine just color


A discolored Blob, loss of one color or blotchy pattern usually in the center of the screen. The problem is becoming all too common with Hitachi projection sets. What happens is that one of the lenses in the optical block (or light engine) starts to burn or discolor due to overheating because of a blocked air filter causing poor air (cooling) circulation. Nothing can be done when the damage is too far-gone except to replace the light engine-at a cost that makes it not worth repair. if the damage is minimal than to reduce further damage, the air filter should be replaced. The Light engine needs to be removed in order to replace the air filter. Be sure to vote/rate me if this helped Thanks!

Blue blob on screen


Took the TV to the shop...there I learned that the obtical engine assambly has been a pain on this type of TV. The repairer suggested on calling the company and to compliant about it, since there seems to be a known problem with that assambly. The company will send the part ($900.00 cost) to the shop and all I have to pay is for the remove and instalation of the assambly.

Hitachi Television Yellowing on the screen


Suggest you call Hitachi and complain. There is an issue with all projection LCD tvs (not just Hitachi) was that the light engine assembly did not have enough vents for cooling. This translates in a green or yellow blob that starts small and grows larger because the LCD screen frame starts to deform with the heat. Guess they did not test with young kids in the house and the tv on more than it is off :-). In March I managed to get Hitachi to pay for the part and I paid for the labor to get this fixed (out of warranty). The new light engine supposedly is better at cooling though I do see a faint 1/4 inch band of green at the bottom of the screen. Blackburn Electronics in Anderson IN has fixed many of these in the Indianapolis area.
