    Replaced lamp this morning per your instructions. When I power on TV green light flashes for a second or two and then red flashes for a second or two then shuts down. I believe i hear the fan also for a second or two. Troubleshooting manual only tells me call Sony Tech. Can you help me on this?

    Replaced according to instructions. When I power on TV, green flashes for a couple of seconds, then red light flashes briefly before TV shuts down?

Hi,
There is lamp cover located on left side of tv if you see it from rear, unplug tv from wall socket, remove that lamp plastic cover, you will see another safety cover, turn its screw counter clockwise and slide its lever to left side and remove that door.
You will see lamp inside, take it out by holding groove at side, put ne lamp in lamp box and put lamp door back in place, then put lamp plastic cover. Job is done.
Lamp replacement procedure is also mentioned in user manual of tv and if you need free copy, click Sony Support and check page-52 for more details.
Hope these info will help you.
Let me know if you have additional question.
Thanks.

    OK, when tv shuts down, does red light blinks, if yes then how many times it blinks after 3 seconds long pause.
    Make sure lamp cover has been fixed back in its position after lamp replacement.

AsI have a sony kds55a2020 tv, I recently replaced the lamp because the lamp light was on. after I replaced the lamp, the tv power blinks 4 times and never comes on. what else can it be?


hi,
Check is the lamp is properly installed or not. If the tv was at working condition before replacing the lamp then then the new lamp is not properly installed. Check one more time. If you can then just remove the new lamp and insert it again. Make sure that the lamp is properly attached. And then check.
ok
