How do I fix a 4flash red light error
Based on the information you have provided for your model and the issue you are currently having with the red light flashing 4 times, we would like for you to try the steps available below:
- Unplug the television power cord from the electrical outlet.
- Disconnect all devices from the TV.
- Let the television remain without power for 2 minutes.
- Plug the power cord back into the electrical outlet.*
- Turn your television on.
* If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
Copied from someone else's post. I agree with the steps this person posted.
If this does not work call the manufacturer. You could see how much it would be to fix vs. the cost of buying a new one.
