i have found one reference of his occuring with what is known a faulty LVDS cables. inside the set their are cables that take the signal from the main board to optical block. they look kinda like computer monitor cables. you might try reseating these cables first. the notes i found said that replacing the cables fixed the problem...something to try good luck
Sony TVs has an Optical Block issue. If there is an issue with the optical block, then there will be green, blue patches or tint on the TV display. Try resetting the TV to the factory settings and try Power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue still persists, then TV may require service. You can contact the Customer relations team at 1-239-768-7547 and ask for the recall issue Sony had repaired free of cost for such issues previously. Hence, contact the customer relations.
The projector part of the tv known as a light engine or optical block is failing and needs to be replaced. Contact Sony, it may get fixed for free under their extended warranty..but it is expiring very soon! It would cost at least several hundred dollars if you had to pay for it.
I'm afraid to say this is probably a problem in the prism. The prism has 3LCDs on it, one for red, green and blue. You can get blue patches if one starts to burn out. If it this, it is not an easy or cheap fix. Could I just confirm that this is a rear projection TV?? (Its in that catogory)
These issues are problems in the light engine (optics block)
the dots are called "starfield" and the geometric is "roadmap"
replacing the light engine will fix the issue. for awhile, sony was extending the warrany on the engine for these issues only, but that may have expired.
Uh Oh! blue screen of death. Your light engine
has warped a little from overheating and is distorting the picture.
Make sure it is getting good ventilation and the fan filters are clean.
My suggestion to you is to get on the phone with hitachi and start
complaining, then keep complaining until they agree to pay for it. You
may have to get the problem diagnosed by a pro before they agree to pay
for it though.
Hope ya fix it!

your tv has a fault in the matrix board the blue driver volt to the screen is missing or some dried up soldering at a pin
