A 5 blink error indicates a bad lamp driver. However a lamp may possibly cause this too. I suggest putting a new lamp in if you have one just to verify the lamp is not the problem. If it still fails with a new lamp then the lamp driver is the problem. This part should be replaced by a Sony authorized servicer. The lamp can be replaced easily by you. The lamp replacement instructions are in the TV's owners manual. Good Luck

check for popped or raised tops on caps in power supply. also try unplugging set for 5 minutes and resetting it. How about does your color wheel spin up? if your color wheel don't startup then your tv will also shut down. also check all fans they all should be running at turn on. if all fails i would say its your light engine.

Commonly it's going to be a power supply related problem. The two boards that need to be looked at is the Main Power Supply Board or the power supply board for the screen. The one that powers the screen, some manufactures call it a Backlight Inverter Board.
If you have some electronic experience, you can sometimes find a Service Manual for the TV over the internet for less than $20. It will have the all resource material for repairing your TV model. It's just the matter of replacing the bad part on the circuit board.
