Problem: TV showing “no signal” or black/blue screen
Check first (and double-check!):
- Video player power on (status light on)
- TV power on
- TV tuned to correct input source, usually HDMI 1 or 2
- All wiring connected correctly
- Power LED lit on powered extenders (see manufacturer’s instructions)
- Before continuing to “next steps,” call Works24, 800-460-4653.
Next steps:
- Bring the video player to the screen. Connect HDMI directly from the video player to the screen. Turn on the screen. Turn on the video player.
- Double-check all connections, make sure the TV is tuned to the correct input source.
If you have a picture when connected directly to the TV, it’s an issue with the extenders/DAs/cable runs.
- Check connections and cabling again. Use a cable tester if possible.
- Test extenders with short patch cables. (Bypass cable run through the building.)
If it works with a short cable run (patch cables), the issue is with the installed cabling. Check:
- High-quality Cat 5e or better cabling
- Cabling not run over 100′ for HDMI
- Cabling not run near sources of electrical interference
- Check wiring with cable tester
Problem: TV intermittently losing signal OR “sparklies” on screen OR distorted/pixelated picture
This usually indicates a weak signal is causing the TV to stop detecting the presence of the video player.
Check:
- HDMI extenders adjusted according to manufacturer’s instructions for gain/impedance, etc. Follow the instructions that came with the extenders to test different settings.
- Cabling not run over 100′
- Cabling not run over sources of electrical interference
- Check wiring with cable tester
Solutions:
- Replace wiring with shielded Cat 6
- Move video player closer to screen(s)
