I have the same tv and i tore mine appart and found the glass plate on the blue spectrum side has a pink film over the glass.... This is a filter for the blue spectrum... The pink film burns up over time and you end up with a blue splotch in the middle of your screen! The glass filter is located only 3/8 inch away from the blue side lcd... Right whare all three collors meet @ the optical prizim.... You can get a replacement filter for $10.. Make sure you buy the glass filter that has pink inbeded in it...(Not the one with a plastic pink filter glued onto it) Good luck!!!

I have a panasonic pt l500u, just started getting large yellow spot in middle of screen- looks like a giant finger print. Bulb was replaced less than two months ago.


Hi:

The problem here is the one of the miniature LCD screens in the unit is faulty, in this case its the blue one. There are three of them inside the unit RED<GRN<BLUE. The blue seems to be failing in your unit, for instance if you mix red and green you get yellow. Have a local shop service the unit and clean and refocus the unit back to factory spec's..

There is no solution with Hitachi products.

If you have read many of the posts, you would have known not to buy Hitachi Telivisions or like me avoid all Hitachi products. There help line is not very useful, they just blow you off. I have never had a worse experience with other manufacturers. Take Onkyo for instance, they had a problem with a chip in their THX receiver and it was a year later ... I called their help line they located a repair store about 40 miles from where I live (in Texas that is not very long) and got my receiver fixed and this was 8 years ago.

Also use Consumer Reports to check the frequency of repair record for the product you are going to buy. In Plasma - Panasonic is a safe brand, in LCD's Sony or Samsung have good repair records.

Research the product before you buy it, avoid walking into a store have the salesperson direct you to a product. And then you save money if you order it online. Amazon online is very good.

Blue Screen w/Flashing light in the middle echoing out to edge


Good Day, you all;

This TV has many problems......at least three boards and many parts on each PCB..... most places charge between $750.00 to $1,200.00 to repair. So, I will let you be the judge if it is worth it. Get an estimate from an authorized service center be fore making final decision.

If you can repair yourself I will be glad to give you the info.....it takes an experience tech about 3 hours to repair.

Good Luck, big IRISH.
