Blue blotches spreading over the screen are failure of the optical block

I PUT MY SONY GRAND WEGA KF-42SX300U 50 in. lcd


Well we need to have in mind that a generic lamp will give you 3500 to 4500 lamp hours and the Phillips will give you 6000 to 8000 lamp hours ,The lamp itself typically uses AC current and about 15,000 volts to ignite the lamp's mercury2.gif vapor gas. The gases inside the lamp react when electricity charges up the mercury gas creating very bright light. The voltage drops to keep the flow of electricity to the lamp.
The symptom of a bad ballast is that you could hear a constant CLICKING or electrical BUZZING sound,my recomendation is to take out the lamp to physically check for any sings,(shatter fillement,black or grey spots in the fillement or smoke ) you can get good deals at http://www.discount-merchant.com/?click=52978
Please keep us posted,

Blue hue accross bottom of screen - Sony KF-50WE610


You can try doing this, turn on the Tv and select the service menu, if that tint also shows on the menu, it's most probable to be your DMD board, but if it doesn't it might be the video board..

Kf-42610 blue hue and blue dots on screen


Hi Guys

The Blue dots or discolouration you are seeing is due too the Blue LCD screen having cracked from excessive heat. This normally happens when you have a power failure while the Television was on. This obviously because the Blue LCD sits next to the lamp - the main cause of heat. The correct part number on the 60" is A-1086-952-A. It is very, very ,expensive.

Sorry to have been the bearer of bad news. Good luck : )
