Using a VGA splitter to connect a laptop to a Devant TV can work, but it's important to note a few things:
1. **VGA Splitter Compatibility:** Ensure that the VGA splitter you're using supports the resolution and frequency of both your laptop and the Devant TV. Some cheaper splitters might not support higher resolutions, resulting in a lower quality display.
2. **Connection Setup:** Connect the VGA output from your laptop to the input of the VGA splitter. Then connect the two outputs of the splitter to the VGA inputs on the Devant TV.
3. **Settings on Laptop:** On your Mac, go to System Preferences > Displays. Ensure that the display settings are configured to extend or mirror the display to the external monitor (TV). You might need to detect displays or choose the appropriate resolution settings here.
4. **TV Input Source:** On your Devant TV, select the correct input source where you've connected the VGA cable.
5. **Signal Quality:** Be aware that using a VGA splitter might degrade the signal slightly, potentially impacting the quality of the display on both screens.
Remember that VGA is an analog signal and may not deliver the highest quality resolution compared to more modern digital standards like HDMI. If both your laptop and TV have HDMI ports, using an HDMI cable might result in a better quality connection.

Change battery. Look for any jammed buttons on remote. If you have a SW Radio, switch it on, tune to a place whether there are no stations, and press various buttons on the remote. If you can listen to some clicking noise, the problem is on the TV sensor.
You should call Devant's hotline now to verify the problem. Be prepare to present the model number and serial number located at the back of the TV. Devant's hotline is 3029700.
