I replaced the bulb on the kds-60A2000. Now the red LED power light is blinking 3 times. I know that indicates the lamp door may not be securely attached. I have replaced the bulb before and had no problem. I am sure the lamp door is on correctly. I am not sure how the TV knows the door is not secured. Is there a sensor or a switch I would be able to see?
Thanks for your help
Re: I replaced the bulb on the kds-60A2000. Now the red...
The tv know the door isnt on because of an internal switch. Make sure all doors are on usually three blinks indicates door isnt on. If the tv still doesnt power on your balast might be out.

Hi, 3 times red light blinking indicates that Lamp Cover has not been fixed in its location properly after lamp replacement. Please make sure lamp cover (its first thing that was removed to replace lamp) is installed securely. Thanks.
The 3 blink code indicates that the lamp door is not secure. If you havent removed the door then its probably the switch for lamp door sensor.
I would remove the lamp door and then reinstall it. Do this with the set unplugged then plug it back in and check operation.. Basically sometimes the lamp door switches become dirty and by removing and reinstalling the door it usually corrects the problem..
If this doesnt work then you will need to either have the set checked out by a tv technician or you can try replacing the switch yourself. But as I said normally just removing and reinstalling corrects the problem.. Good Luck!
According to the manual (pg 53) : "If the lamp is not securely reattached, the self-diagnostic function may be triggered and the POWER LED blinks three times."
I have a Sony KDS-50A2000 50 in. HDTV Television. I just replace the lamp because I got the message that appeared on the TV. Lamp needs to be repaced. I replace with a Sony lamp and now TV cut off after 2 to 3 hours off watching the TV. Any Idea what is going on with this TV
it is a bad fan. it also could be a power supply. Quite often the real problem is dirt clogging up the fan(s) to the
point that they need to be replaced. Operation of the set in a dirty
environment is not a good idea
