Still cannot get any picture at all - completely black screen
I have the KDS-50A2000. The TV abruptly shut off. When I turned it on again, it blinked seven green lights and then four red lights. I replaced the lamp to find out that it did not fix the problem. After reading several posts, I checked the fans today. I blew two and half years of dust out of the main fan and the lamp light fan. It worked!
Check the fans located in the rear of the set. the fan that cools the lamp is most likely not turning. Power the set up then take a flashlight and see if it is turning. if not then replace that fan. there are also a fan or two in the inside of the set that could also be bad but not as likley.

yes the red light blinks 4 times
I have no picture but the red light still keeps on blinking on the lamp sign
are there any lights on the front of the set blinking, if so how many times does it blink.
