You probably need to get the bulb changed and or a new wpower supply board for the TV. How old is this?

Boz Mar 09, 2009

Sony had a quality issue on the power supply module/board with a couple of the components. Usually it is two capacitors and a resistor that get replaced. Some techs believe it to be a thermal issue with the relationship of the distance from the bulb to the powersupply board.

You can probably try to source a replacement board off of Ebay/internet, if you feel up to it.

Sony Grand Wega- Red light Blinking

I would have to say you have a bad projection lamp!! They do NOT last forever!!! About 3000 hours is normal. If this is out of warranty--about $300 in--house repair or so.

Sony grand vega 55" will blink green for three times than red blinking under the power light. nothing comes on no sound, no picture and no fan's are running. Tried to change the bulb, power board...

Your problem is your thermal fuse.It is located around the bottom of the compartment that houses the lamp. You will have to remove the lamp and take the bottom back panel off. Then you will have to remove the fan. I ordered the thermal fuse so I would know what I was looking for when I started to replace it. If you take your time and are patient enough you can fix it yourself. I fixed mine and it's working great.GOOD LUCK!!!
