Hello everybody! When i was testing my hps 40 with its own generator picture dissapired from LCD. The reason: i made a short circuit between probe and screening lining! So, the 19 output of IC12 PIC(PWMCONTRAST) died. No PWMCONTRAST - no any picture at all, although oscilloscope work and LCD LED was OK. I desided to cut 19 output off (it was shorted to gnd) and to take a PWM signal from 39 out PWMYPOS. Now it works well, but contrast depends on Y-position. No problem, i think =)
