SmartTV+LibreelecPC

    • New

    Hello everybody. I've got a PC running LE, connected to LG smartTV through HDMI. The TV also takes signal from external antenna for watching programs in Greece.

    The strange think is that when I power on the Libreelec-PC, I loose the TV signal. It looks like something blocks the antenna signal. A message appears that there is "no signal".

    So I cannot watch TV while Libreelec-PC is powered on, I can work with Libreelec-PC but when switch to TV get the above message "no signal"!!!

    Any idea what's going wrong, how can PC or cables be confused with TV and make this problem?

    Please help. Thank you.

    I'd guess that "no signal" refers to the HDMI input signal and when the LE device is powered on the HDMI input is being switched, but the TV fails to lock on the resolution and you see an appropriate message. Killing the antenna signal sounds really weird and I heard nothing like that before.

    If your PC is not housed in a shielding enclosure and/or to near the TV, it can radiate into your antenna cable and block the TV signal. Please check the isolation of your antenna cable and the used HDMI cable, sometime also another power supply for the PC.
    I had encountered a similar problem with a friend who had a Bluetooth transmitter for headphones attached directly to the back of her new TV. The SAT tuner was unable to find a transponder until I found and removed this construction.
