Title: YURAKU M22ABJ with blown powerboard EMAX PWR0652006001
Post by: xerian on January 20, 2015,02:01:42

Hello. I'm strugling with powerboard EMAX PWR0652006001 for Yuraku monitor.

http://www.emax-co.com/english/products_show.php?queryrecno=5757&cno=2&c_no_1=3&c_no_2=6

 It has no power on any rail. By testing with multimeter power comes  thru main transformer. I've spoted two burned SMD resistors. One I've persumed by marking JR2 is SMD jumper (0), but other one with marking PR22 (leads from optocoupler) is not readable.
So Im asking if someone could post a shematic diagram for this powerboard.
