Tanks !!!

C806 200v 680uf capacitor and R807 470k ohm resistor
only other faulty parts were
C441 250v 1uf capacitor and C424 50v 1uf capacitor
fitted the chassis into a dance stage I found with the pm1745 unit in and all works fine still after 2 days
checked C441 on the chassis now out of the dance stage and thats shot too

HI
These r the values that I have written down from a good monitor.
R805 = 1k5
R807 = 470 ohm
R808 = 10k
R817 = 1k5
R819 = 3.2 ohm
R811 = 6k8
U should also check
Q802 = A1091
Q803 = C2330
Q804 = C2330
Check the chopper C3831 and the Line Output D1887. Also replace C441(Line drive smoothing cap)
Also check all the semiconductors on the Power Supply
Cheers and good luck

Thanks drslots, I found maybe the same drawings because the resolution was very low, imposible read the values..
In some days i will tell if it works, because this chasis belongs to a Sega Rally wich is to 150 milles from here !
Sorry for my english

No.. There is a resource section on the site, but that is mainly for Naomi related stuff. PM Pete to know more.
