I have an openbox V8S it now reads no signal and cant get any channells

You have a weak signal I suspect.

Or your box is getting too hot and crashing. One way to keep them cool is to stand them up tall, not flat.

Check the remote control for its infrared emission. Check it with fresh batteries. Check it by pressing all the keys. You can detect the presence of infra-red emission from the remote control, using a cell-phone camera. If you wish to get more details about how to check a remote control, please visit this site. One among the posts has details about it. Surf the site with patience. In some cases, the remote control might need to clean.

Hi Alan,
It seems to me that the best way to solve this problem would be to uninstall/ remove the programmes. Just be careful and check that you don't compromise any data!

Did you select antenna in the setup menu?
If you did and still can't receive anything you may not be receiving signals strong enough. Read the setup instructions in the manual. link below.

The TV reads the PC via the HDMI out from the computer. You must make a direct connection from the PC to the HDMI input on the TV with a proper HDMI cable. Once that is established, you need to be certain what HDMI Channel is represented on the TV, HDMI #1, 2 or 3? Etc. Best you turn on the PC AFTER all connections are made and the TV is in full operation and the channel HDMI 1,2,or 3 etc. are on. Now turn on the PC and see if you get a connection. You may have a picture if you are streaming a video, and NO sound. If so, reset the Audio by clicking on the speaker icon at the lower right of your computer screen, and in the Volume Control Options select the output you wish to use.

You don't specify what type of equipment you have. Try unplugging the DVR from the electrical outlet for about 10 seconds and plugging back in. You can also check your cables between the DVR unit and the TV to make sure all cables are secure. I hope this helps.

There may be an input button on the remote, or on the TV, that allows you to switch from the standard ATSC tuner to the DTV tuner.

Let me know if you can't find it and I will dig for an owner manual. But the above should allow you to switch tuners and input sources.
