If you replace the lamp and need to reset the Lamp Timer Reset procedure is: With The Set In Standby Press Display, 5, Vol Up, Power on the remote control Press Jump 3. Or, To Display The Lamp Time Press 2 Nine Times. To Reset Press 3, Mute, Enter. One of these should work on your model. Make sure you replace the bulb first. There is a possibility that the ballast could be damaged by a defective bulb as well.

Picture will come on and then go off after a couple minutes

This usually means the Lamp is failing. Replacing the Lamp usually fixes it. I would only use a Sony Replacement.
You can order one from Sony at 1800-222-SONY or you may be able to pick one up from a local Sony Retailer.

5 times Red LED blinks means Lamp Driver Error. (KDF-55WF655)
2 possible reasons, either Lamp is gone or Ballast Supply got bad.
Replace lamp first, in most cases it solved the problem.
How old is this TV and did you replaced lamp recently?

Sony KDF 55WF655 rear Project tv Power/standby light flashing

This would be an error code indicating a problem.  You didn't mention if anything else was going on with the TV as in no picture, or no sound.  If the TV is operating just fine, there could be a bug in the software causing this.  If there is a problem, the best thing would be to contact Sony and relay that error message and go from there.
