Lg tv screen comes on slowly

[layad]

Hi. Lg tv when I turn it on the screen shows unlock tidy horizontal pixels on the top without backlight. And step by step for 20 minutes the full screen shows up perfect. Is it the panel?

If you can see the pixels are you sure the backlight is working?

It sounds like a panel defect.

Disconnect the ribbons between the screen and the tcon board, one at a time and power the set on.

I would say most likely the panel is bad.
