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

I had the same problem with mine. I took the lamp out, comes out from the front, and cleaned the screens on the top and bottom of the lamp. If these are dirty, mine were, they are preventing the bulb from dissipating heat. This causes the tv to shut off the lamp to cool it down. Mine works like a champ now.

Its time to replace Lamp. Please buy original Sony Lamp for Sony TV and avoid aftermarket or compatible parts for good performance of TV.

The optical block is defective. Sony sometimes warranties these even after the 1yr warranty has expired. Contact Sony support and have you full model and serial number handy.
