TV has bad horizontal lines and flickering image, help!
I recently was given a free Phillip's t.v. , model #: 55pfl5402/f7. I got it for free because the screen was flickering, but boy is it flickering. The whole screen flickers in and out with with black and white lines. Image is stable for maybe a second but not long. TV is a smart tv and connects to internet, loads up apps and everything. Seems like the only problem is the screen/lcd.
Could anyone point me in the right direction as far as what to check/fix?
