Replaced bulb in a kdf-e42a10 and worked for about 8 hours

Replaced the bulb in my kdf-e42a10 and it worked fine for 8 hours and then the bulb blew again. I pulled off the back and checked to see if both fans were working and they are. I received a replacement bulb and am afraid to install it and have the bulb go out on me again. I turn on the TV and the red light blinks 3 times. Any help would be appreciated.

Best thing to do is never use your bare hands to put the bulb in . use a clean paper towel always .the reason is you have oils in your skin and if you touch the bulb you just put oil on bulb.

3 times red light blinks shows that Lamp Cover is Open. Please put back lamp cover properly.
I would recommend to always replace with Original Sony Lamp and avoid aftermarket or compatible lamps.

Ony KDF- E42A10 lamp needs replaced, should I replace the fan also, just got a new lamp 8 months ago picture is dark


Usually the lamp gets brighter when it begins to fail. I would check to see how dirty the inside of the set is. There are beam splitters and lcd filters in that set and if they get dirty then you lose picture quality.

Heard a pop , bulb blew out , replaced bulb , it worked for two days , now red light blinks three times pauses then three times and so on , tv won't turn off light won't turn off unless I unplug...


3 blinks indicates lamp door is not on or has not been reinstalled properly. This also could mean the lamp door switch has failed itself. Try removing the lamp door and putting back on, if that doesnt correct the problem then I recommend having the switch replaced.

My parents have a Sony KDF-E42A10 42" LCD TV. They have audio, but no video. Screen is black. Do you think they need a bulb replacement?


Yes, if lamp has not been replaced in last 2-3 years then it is lamp problem. If tv does not shut down and its standby light does not blink in red then lamp is cause of problem, replace it to fix tv issue.

I replaced the bulb recently on my tv and did not push the bulb all the way in. I had the same issue you are having now, and I was able to get it to work when I realized it had not been installed properly. Make sure you push the bulb in all the way then push down on it so it sets in nice and snug. Sounds like someone replaced the bulb and installed it wrong like I did the first time. Good luck.

Hi 425hunt

When did you purchase the lamp and how long has it been since it was replaced ?

A lamp normally comes with a warranty of it's own.

I've had a couple cases like yours before.
