Hi.
I´ve been given an old CRT from Panasonic, it´s almost new, it was storaged and almost not used since bought.
It is imaculate inside, almost no dust or debris inside.

Hi,
Suddenly all HDMI ports stopped working on a Panasonic 50" TV. This is model number TX-P50XT50B and has worked fine for years.
The TV turns on but no joy on either HDMI-1 or HDMI-2 and I've tested it using an input device and cable that works fine on another TV via HDMI.

Kind regards,
