Here’s the [https://www.electronica-pt.com/esquema/tv/panasonic-esquemas-tv/panasonic-tc-l58e60-chassis-la41-66276/|service manual] for the TV. (the specifications in here state LCD panel/LED backlights)

Here’s the [https://www.electronica-pt.com/esquema/tv/panasonic-esquemas-tv/panasonic-tc-l58e60-chassis-la41-66276/|service manual] for the TV. (the specifications in here state it has a LCD panel with LED backlights)
On p.16 of the manual there is a ''LCD Panel test mode'' procedure that may be worth checking to see if it is a panel problem or an A board problem.
Also you said that the screen gets darker so maybe there is a backlight problem as well. Check for +24V on pins 7, 8 & 9 of P4 connector on the P board, as these are the 3 power supplies for the LED backlights. See schematic on p.30 of the service manual.
