The 5 blinks is indicating the lamp ballast needs replacement your model uses the Sony lamp Ballast 147401211 for sony models KDF42E2000, KDS-50A2000, KDS-50A2010, KDS-55A200, KDS-60A2000, KDS-60A2010, & KDS-60XBR2 amd LDS-R60XBR2
Which is available at the bottom of the page at the following link. The ballast comes with installation instructions,

The tv know the door isnt on because of an internal switch. Make sure all doors are on usually three blinks indicates door isnt on. If the tv still doesnt power on your balast might be out.

you have to replace the bulb what happening is the life hours on the bulb is almost over just replace the bulb soon or later you will see a red flashing light sometimes that's indicating the bulb needs to be replaced

Lamp cover error, lamp cover is not attached securely. Please check the lamp cover if deformed. If the lamp cover has been deformed due to excessive heat exposure, replace it with a new one. Sometimes the lamp cover melts due to overheating caused by poor air ventilation. Clean the fan and lamp compartment to avoid overheating....

I do believe that is a bulb problem. or possibly lamp door switch is faulty.

Replace the thermal fuse located right by the lamp.

Check the fan that cools the bulb. It is directly behing the bulb. It should turn on when the power comes on. It apparently has a safety to protect your tv(and home). mine is in the process of going out. looking for online solutions as we speak.

If you pull the right side out (as you look at the front), get you ear down to the fan exhaust area and turn the set on. If you do not hear the fan turn or feel air being blown out, then you have a defective fan. It is a common problem.
