These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.

With your PS3 turned off, press and hold the Power button on the front
of the PS3 for about 10 seconds (the system will beep as normal as it
starts up but after 7-10 seconds it will beep again). The video
settings should now be reverted. Doing this will also reset any theme
settings. try this? seems to fix alot of issues.
One of the circuit boards should be replaced inside, probably the power supply, the good thing is that screen is ok and it's a most expansive part, you can take it to the local repair shop for diagnostic and repair.
Just so you know guys (and this procedure is not for the faint hearted!). I had the slow one second red warning light flash. I checked the bulb, which was find and I left it powered off for 48 hours. My projector is no longer under warranty and would have cost me over £300 to have it looked at. I ventured inside to inspect the boards, once I removed the main board to check the power supply I heard movement from one of the light ducts. It took me a while to removed enough to discover the fixing screw which holds the imaging cube in place (which is between the 3 light ducts and the projector lens) had come out (!?) and was rolling around inside the unit. This would also explain why sometimes I could not focus my unit properly. I remounted the imaging cube, put the whole thing back together and PRESTO! My projector is working again. email@example.com

This behavior occurs when the internal temperature of the console
exceeds the acceptable limits. You may think of this as too hot,
overheating, and so on. Make sure the fans are operating and the system
has adequate ventilation.
Since you've been inside it's possible that a heatsink or some other part of the cooling system is not working properly or is loose. Check all these!
