DIY Fixes for Sharp TV Channel Scan Problem
Explore the below-mentioned troubleshooting methods to resolve the Sharp TV channel scan problem effectively. You can also follow the steps below to rectify the Sharp TV error code 202.
Check the Cable Connections
Inspect if the antenna cable is firmly plugged into the TV’s output source, as a loose connection can cause scanning issues. Also, check the cable connection at the antenna jack to ensure it is properly inserted. Set up the antenna on your Sharp TV by repositioning it accurately, as incorrect position or direction can affect signal strength. You can use a station location tool to position the Antenna. A station locator tool determines the direction of broadcast towers and adjusts the antenna accordingly. If reception issues persist, proceed to the next technique to resolve them.
Check the Input Ports of the Sharp TV
Sometimes, the problem occurs if the input is not working on Sharp TV. Ensure the coaxial cable, especially the screw-on connection, is securely tightened to the TV input. Examine the cable for any damage like bending or cracking, and if so, replace it immediately. Then, initiate an auto-channel search and check whether the channels have been listed.
If the TV fails to detect channels, the issue may lie with the tuner. Test the tuner by connecting the coaxial cable to a different TV and running an automatic channel scan. If the scan fails on the other TV, the problem is with the TV tuner. If the scan is successful on the other TV, the issue may be specific to your Sharp TV.
Note: If you require a replacement cable, search for the cable that matches your Sharp TV model number.
Update Sharp TV Firmware
Software glitches may occur because of outdated firmware, which may be responsible for why channel scanning fails to work on Sharp TVs. You can update the Sharp TV firmware to the latest version to fix the issue. Ensure your Sharp TV has a strong WiFi connection during the updating process. After installing the update, perform an auto-scan on your Sharp TV to see if it works.
Restart Sharp TV
Restarting your Sharp TV often helps clear any issues interfering with the channel search. It will refresh the TV functions so you can perform an auto or manual scan later. Go to your Sharp TV settings menu to restart the device. For Sharp Aquos TV, unplug and replug the power cord. Then, switch on the TV to perform a reboot. Once done, check if the channel scan works.
Rescan Channels on Sharp TV
If some channels are missing, try rescanning because stations sometimes change according to the broadcast. If auto-scan doesn’t work, try a manual scan on your Sharp TV.
- For Sharp Android/Google TV, go to Settings, click Channels & Inputs, and select Channels. After that, tap Channel Scan, select Country/Region, and tap Finish.
- If you use Sharp Roku TV, click Settings and choose the TV Inputs option. Select Live TV and click Set Up Input. On the next screen, click Scan for Channels and tap Done.

Reset the Sharp TV
Performing a factory reset on the Sharp TV will help retrieve lost channels. However, it will delete all personalized settings, installed apps, and storage files. So, you should set up the Sharp TV from the beginning. After that, connect the antenna cable to the TV firmly and do a channel scan.
Contact Sharp TV Service Support
If you still have a channel scan problem, contact Sharp TV customer service to schedule an in-home service appointment. In case any hardware component is faulty and they recommend replacing it, check whether your Sharp TV is covered under warranty.
