Blue light

You cannot. The blue blotch is a sign that your optical block is going out. This will only get worse. The optical block will need to be replaced. This is not cost effective.

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.

Sony Grand wega

This sounds like the Sony blue star failure and this problem is under Sony extended warranty. Call Sony with your model # and serial # and tell them them you have the blue star issue and they will refer you to an authorized Sony service center and the repair will be free.
