Sorry to dig up an old thread for an old tv. But, I'm having the "flickering" issue on my KDS-50A2020. The TV was originally purchased by me, brand new from Best Buy, on Memorial Day weekend back in 2008, I believe.
About a year ago, 5 days before the Super Bowl, I had my original bulb finally blow out on me. It literally exploded. As you can imagine, I wasn't a very happy camper. Anywho, I decided not to buy the lamp from Sony
directly due to the $250 price tag. After many hours researching on forums and online dealers, I found that the Philips brand was to OEM part. There were many knock-offs out there like OSRAM and the like which didn't perform as well.
I ended up finding a online dealer
on ebay that sold the lamp
I was looking for.
Everything looked great with the new bulb. I forgot how good the picture actually was.
Anyway, on to my problem: About two days ago, I turn the tv on and notice the flickering. I tried turning it off and on again a few times which didn't seem to help. Then today, I turn it on to catch up on some shows, of course it's still flickering, but after about 10 to 15 minutes, it stops, and hasn't done it since. It almost seems like something needs to be warmed up. I'm not quite sure what's going on there. However today, I'm going to leave it on all day, and check on it to see if it comes back after time.
So, I started perusing around on the internet, and came across this site, which seems to have knowledgeable people and information on it.
As others have recommended, I looked up the hours on the lamp. It's at 1350 hrs.. Not a whole lot, and like I said above, it's only about 11 months old. I think it should last a hell of a lot longer than that. I don't know haw many hours were on the orignal, but it was about 4.5 years old. I guess I don't watch a lot of TV.
At any rate, I'm probably gonna shell out some cash for another lamp assembly from the seller on ebay which I purchased from before. I just hope this new one lasts a bit longer than 11 months. I just can't justify spending $$ on lamps every year. But at some point, I need to cut my losses and get a newer, better TV, that doesn't require a bulb.
Hopefully, it's just a bumb bulb I got. If it's anything else, it's going out on the curb.
Thanks for your time, and again, sorry for digging up this old thread for an ancient television.
