    I need help I am repairing monitor LCD HP L1706 which do not powers on.
    I have replaced SG6841SZ PWM Controller SOP-8 and SMD resistors 47 Ohm, 15 Ohm which was buried and AP2761I-A N-Chanel MOSFET one diode FR107 and one germanium diode. I have found nothing else bad and the monitor even doesn't powers on.
    Potrzebuję pomocy jestem naprawy monitor LCD HP L1706, które nie uprawnienia.
    Wymieniłem SG6841SZ PWM Controller SPO-8 i SMD Rezystory 47 Ohm, 15 Ohm Który został pochowany i AP2761I-i N-MOSFET Chanel diody FR107 jeden i jedna dioda germanu. Znalazłem nic złego i monitor nie ma nawet uprawnień.

    have you checked the power supply electrolytic plate?

    I have'd burned out the PWM Controller SMD chip U850 and some SMD resistors R861 and R857 one fuse resistor R859, one germanium diode D855, one diode D851, which I replaced with SG6841SZ, even the AP2761I-A N-Chanel MOSFET Q850 was replaced and the electrolyte 470uF 25V capacitors C1,C2,C864,C862,C855 in power suplly were all changed and it doesn't work.
