The power supply or part of it can be going in to protect mode because something is failing causing improper loading. This can even be the power supply itself. The only way to know is to try the different modules in the set. Once you get to the module that is failing, you leave the new on installed. This is how these sets are serviced. It is a similar approach to how computers are serviced.

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

I have a similar problem. Just found out a possible solution yesterday. I am waiting for my lamp but here's what you need to do if you have replaced your lamp. Go into self diagnostics mode: Switch of your TV via remote, you will see red standy by light. Now,on the remote press "Display"=>"Channel 5"=>"Volume Up"=>"Power Button". All these keys need to be pressed within 3 seconds. You will now enter the diagnostics mode. Press "Jump" on remote (bottom right) 3 times and then press "Channel 2" 9 times. The screen will display your current lamp hours used.
In order to reset your tv to factory settings and for the new bulb to work you must reset this timer or else your TV will assume you are still using the old bulb and will automatically kick in "over protection mode". So here's what you do once you do on the lamp hours display screen. Press the "Channel 3" button on the remote 3 times then "Mute" then "Press Enter" to reset the timer to zero. Your TV should now work as normal. And remember, whenever a part is replaced all factory settings must be reset to zero. To do this, follow "Display"=>"Channel 5"=>"Volume Up"=> "Power Up" to enter service mode. Finally, press "Channel 8" and then "Enter" to put the TV back to factory settings.
The above mentioned is usually performed by a service technician and they charge somewhere around $95 diagnostic fee. You just saved this charge. If you see flashing red lights count them when they flash in sequence. This is a code for the techs to tell them what is wrong. These flashing red lights sequentially flash from 0 to 10 times to identify a problem. Usually, when the bbulb goes bad the only thing that might need to be replaced would be a "lamp Driver" aka "Power Block Assembly" $116.25 online from Sony, or the ballast. Sometimes, if you do not have a video a Thermal FUse can go bad which only costs $4.80 for the KDF60-XS955 but the techs will charge you over $300. You can do this yourself if you can get your hands on a service manual.
Hope this info helps.
Good Luck to you all.

helloFive blinks - AKB circuit (automatic kine bias), the
timer/standby indicator blinks for about 30 seconds then goes to the
self-diagnosis function. Something is wrong with the video. Check video
out, Q705, 732, 761 and other components on the C board, also check
Q218, 219, 220 on the A board. In addition, unit could be in IK
blanking, try turning up screen slightly.

Before you replace the lamp I recommend trying to clean/dust the lamp component and lamp plug in area. I had the same problem and was able to resolve it by simply blowing the dust off the lamp components and fan. Use a can of high pressure air to get into the cracks and crevices.
