LG 39ln575s - power ON, backlight ON but no screen.
I checked TCon board V390HJ1-CE1 and VCL -8V, VCH 30.2V.
Display is HC390DUN. With both strip is backlight only - nothing on the screen.
If I put 1st strip off, I see 50% black 50% white. If I put 2nd strip off, see some lines vertical/horizontal with pink color (probably color of LG logo) and after that, white on thle left corner.

The IC chip CM501 (probably booster for VCL and VCH is hot - after 1 minute is not possible to put finger for more than half second.. So I think it has got about 70C. Is it normal?

Has anyone voltage for test pins on the TCon board?
Any idea? Thank you.

No, this is not normal, either there is a short circuit at the outputs of this chip, or the chip itself is not fixed.

OK, I will buy a new T-Con board and try it.
