There are several methods you can follow in order to fix no signal issue you are facing on your TV. Here we have discussed some of these convenient methods:

Keep a check on your Setup box or cable box

Sometimes, your setup box or cable box is the reason that your TV faces no signal issues. Whether you are using an SD box or an HD box, every setup box provider uses a new firmware and updates it in the background. This means new satellite settings will be uploaded in that operator.

Due to the change in satellite settings, your device may not get fully integrated with the adjustments and result in no signal issues. Therefore, if this may happen to you, then you can simply unplug the power cable from your cable box and insert it once again. While doing this, make sure your TV is switched off and unplugged.

You may also solve this issue by pulling the smart card or view card from the cable box for a while and then insert it. Make sure to follow this step very firmly without applying any pressure. Once you reinsert the card, your problem may get resolved.

Check Cable or port points

In most cases, the main reason behind no signal issues is related to HDMI cables or ports. HDMI or High Definition Multimedia Interface problem occurs when the connections are not fitted in a proper way.

This means if the connections are not fitted tightly or slipping out of the ports, then this may be a serious issue and can cause no signal problem.

One of the reasons your connections are not fitted tightly is that your port has slightly damaged. Do not worry, and there will be nothing serious. You can call the TV mechanic and simply migrate to an alternative HDMI port. You can also check by reinserting in the old HDMI port.

If this also not works for you, then you need to upgrade your HDMI connector. Once you solve all these issues, your TV may start working.

Solving Bandwidth errors

In some cases, the no signal problem in TV occurs due to High bandwidth digital content protection errors. This anti-piracy measure suggests that your device may not be able to receive signals or any cable TV content. Nowadays, all modern TVs are HDCP compliant.

But, if there is any problem in your bandwidth port, then try to solve it. You can remove the offending device connected to your TV, and your problem may get solved.

Keep a check on base channel issues

Sometimes this issue occurs due to different base channels. While 1 or 2 is the fixed default setting on your TV remote, then you may change it to 3 or 4. This change should be done on TV remote only, and there is no need to detangle any TV cable or your service operator. You can also reverse the order to start your cable box first and then your TV in order to solve this issue.
