schematic wanted for sanwa pm1745 monitor

[OldFoo]

Hi my friend , Iam from Argentina and I have some problem whit the same chassis ... I need some resistor values (they burn and are black) they are R805, R807 and R817. Can you help me? please!

Tanks !!!

Cesar

for the wrong voltage input only damage seems to have been



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

[OldFoo]

Sorry R807 = 470k

[OldFoo]

Thank you, i will check all you say and hope can help too. tanks again!

sorry for the delay, a little late i know but if you need the drawings i have them ,there not the best but may help



pm me if you need them





btw does the site have a file section section they can be uploaded to

[OldFoo]

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.
