Question about Sony Grand WEGA KF42WE610 42" Rear Projection HDTV-Ready Television
I have a 42" sony grand wega and when we came home tonight, the tv was off, but it looked like it was still on with just a lit up black screen. We tried to turn it on, but the green light is flashing with no picture. I just replaced the original bulb in it about a month ago. Could this be a bad bulb?
Does the green light ever go out and a red light blink? normally sony generates a diagnostic code using a series of blinks with the red light only. There is info on the net about a software upgrade many sony's need for a problem just like this. Have you tried unplugging power for at least 2 minutes and then replug? If not try it and see if it will come on. If it does it needs that sony software upgrade. If not, I'm not sure off the top of my head what it could be.Normall bad lamps will give 3 red blinks. You could always look at the lamp then reseat it and the lamp door.

If your Sony Wega will not turn on, the front green light blinks, you hear a faint whirring sound and the green light turns red and flashes, it probably means the lamp inside the set is no longer working. If you noticed the screen beginning to dim in the preceding days or weeks, this most likely is the cause.
If the green light flashes and the picture comes on momentarily but then goes off, and the green button flashes until the set restarts, then the seal around the lamp mount is loose and needs to be refitted.
If the picture on your Grand Wega cuts in and out and the green standby light flashes, both of the set's STKs need to be replaced. STKs are small chips on your television's circuit boards and are identifiable by their labels. The specific STKs used in your Grand Wega TV will be identifiable by the numbered labels on top of the STKs.
When you plug in your Sony Wega and hear a loud popping sound, it's probably caused by a defect in the high-voltage circuit. Let the professionals take care of this one.
If, after turning on your Sony Wega, you can hear your set but the screen is black, you most likely need to replace your projection lamp.
