Problem may be lamp is failing or ballast which operates lamp may be Bad. Could also be Temperature fault from Inoperable fan or Color wheel. Bulb of course is first choice of possible problem followed by color wheel then ballast. Color wheels usually will start making bearing noise when they start to fail. Hope this helps.

I have a picture but the tv will periodically turn itself off during the day and then flash the 3 blinking lights...anyone know what the problem could be. We can fix it ourselves if we knew for sure what it is.

I get the same problem (4 flashing red lights).
I done some internet troubleshooting and narrowed it down to an overheated power circuit card/fan issue.
It turns out one of the fans is failing and will not rotate at the appropriate speed to cool the power circuit card, this will kick out the 4 flashing lights from the diagnostics.
In lieu of replacing the fans I have a temporary solution:
For my TV (kdsr50xbr1) the fan in question is located on the far left side (facing the rear). You will see a grill on the back of the TV showing you where the fan is located.
First, get a can of compressed air and blow it into every fan. This will clear away a lot of dust and help the fans move easier.
There is one blower type fan located inside the TV, remove the back panel and look for a tall yellow circuit card just to the left off the center of the TV. Behind that card is a blower (stands upright looks like a tube). Blow air into that blower, you will see a lot of dust come through the duct and out where the large fan in the center is located.
Put everything back together. and provided the fans aren't too far gone the TV should be working again.
Also, if the issue comes back, try this:
When you turn on the TV, shoot a short squirt of compressed air into the fan (Far left facing the rear). This will give it a kick start and bring it up to speed.
It is important to note that the compressed air cans do contain a liquid and as such are not compatible with electronics when they are plugged in. Try your hardest to keep the can upright and not allow the liquid to squirt out where it shouldn't. If it does it will evaporate in a few seconds.
Ok, relatively long post, to summarize:
1. Open back of TV, blow compressed air into every fan to clean them.
2. Blow air into whichever fan is causing problem if it happens again.
3. Keep the can upright if the TV is still plugged in. Don't sue me if you fry your TV.
4. If this doesn't work (has for me) replace fans

3 blinks is a lamp cover error, did you make sure that the lamp cover is screwed in tight? Also check the lamp cover for deformity, there is a problem with your model where the set over heats and melts the lamp cover a little causing it not to make connection with the lamp cover switch. Let me know if you find either of these problems? If not we can troubleshoot a little further.

I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions
