It is symptom of dying lamp and tv requires new lamp.
Existing lamp in tv has reached to end of its life span and causing that problem. If lamp has not been replaced in last 2-3 years, just put new lamp in tv to get it back in business.
Thanks.

hope this helps

The sony model KDF-E55A20 has no sound or picture. The power led flashes red six times consecutively after being turned on.


Your thermal fuse has popped and needs replaced. This TV has a service bulletin regarding this issue. You should contact Sony for the replacement part/kit.
