Default Re: Panasonic TH-50AS700 - Can I rely on LED tester results?

1 blink code on a Panasonic is bad backlight so you likely have an intermittent LED in the string that is failing at higher current than your LED tester can put out and when it warms up. Take Budm's advice and lower the backlight level to see if it stays on longer. Also turn off any ambient light sensor setting that could crank up the backlight in a bright room.
