What to do if my Grundig TV screen is on (black screen), but there is no channel?
If your Grundig TV screen is black but on and there's no channel, check if the antenna cable is properly connected. If it is, try running a channel scan to program the TV stations. Also, adjust the brightness, contrast, or color settings. If the issue persists, test with a different TV station to rule out problems at the broadcast source.
How to fix ghosting, reflection, no color picture but no sound on Grundig 50 GHU 7970 B?
