Bugs in your TV’s software (or un-updated software)
When your Sharp TV’s power light is blinking, it is usually a sign that bugs in your TV’s software are preventing your TV from starting up. Alternatively, it could mean that your Firmware (software) isn’t up to date.
Software updates usually come in to fix bugs. So, if you haven’t updated your TV’s software to the latest version, the bugs in your current software version might be causing this issue.
Mechanical issues (loosely attached power plug)
Sometimes, when your TV’s light is continuously blinking, it is a sign that you should check your power plug. When power plugs are loosely attached to sockets, they may start heating up (or cause your TV to heat up).
The blinking lights, therefore, tell you to immediately check (and re-plug) your power cable.
