Re: fixed but got grainy/noise picture on my plasma now -LG 50PA6500
Ramp_up & Ramp_dn waveform is set with a scope, but you can do it by eye, Any firmware update on LG's site would be for the main board, the control board ROM firmware needs a special jig to connect between the pc and the control board to up date it. I thing this is a newer panel and the control board rom may not have newer firmware.
