Which are the Most Common Sharp Aquos Blinking Codes?
Here are the three most common Sharp TV Error codes:
1. Sharp TV Aquos TV Error Code 03
This error code usually appears on the screen as ‘Start0up communication error.’ It specifically means that your TV is only receiving the initial communication. It can’t accomplish the rest of the work.
All error codes ranging from 02 to 09 mean the same thing as code 03. However, the 03 code is the most common.
You’re highly likely to receive these error messages after a power outage or after removing your power cable from the TV suddenly. Some causes of the code 02 to 09 errors are not known, but that should not hinder you from fixing them.
2. Sharp TV Error Code 21
If you notice error code 21, your TV is most likely running into power-related problems. So, if the power supply is not working correctly, you are highly exposed to this risk.
3. Sharp TV Error Code E203
This code indicates that the broadcast you are trying to access is down. In other words, the channel you want to watch could be down from the backend, or your cable service might be entirely down.
