I have a Sony 50 inch LCD projection TV model KDF - 2000 when I turn on light goes green and blinks 4 times and then it goes to the red light and it blinks and 3 time series

SOURCE: kdf-60xbr950 - red light blinks 3 times for a minute and tv turns off

same problem as others 3 blinking green lights then orangey colors then 3 red blinking lights afterwards shuts down fan runs for about 2 mins solution check your door cover for warpage or deformed just a bit under set screw there is a push in switch try and push it in with q tip while holding turn on tv if it works then that door is deformed and defective change it

thanks for solving my issue tv works again very helpfull thanks

4 flashes is a bad fan, 3 flashes is lamp door switch

in this set 3 blinks means lamp cover not set properly but i think that your problem is your 6x red blinks that means you have a problem in the audio section in your set(missing a voltage) or a themal fuse open.

thermal fuse. it sits below the lamp and has popped. replace with new fuse or just short (eliminating fire protection) let me know if you need instructions.

Its not the green light that you should be count but the red. How many times is it blinking? Here is a quick update of the errors that are most common.

3x - Lamp switch not engaged
4x - Fans issue
5x - Lamp
6x - Thermal fuse
