Re: Nanao MS8-29SU

you won't find them, that info you posted is for nanao ms8-26su
for the ms8-29su you need to replace following
ic 401 la7832-and check for broken tracks
r428 2.2ohm metal oxide

Re: Nanao MS9-29A image rolling

just want to point out that some jamma looms have video ground on pin 14 and some have it on pin 1, some game boards have video ground on pin 14 and some on pin 1- if you link 14 to 1 quickly then you can prove it

its not a chassis fault 100%

Re: Nanao MS9-29A image rolling

i reckon that is a video ground problem, you may need to link the video ground pin 14 to ground pin 1

Re: Nanao MS8-29SU

that info is not correct, it looks like a modified post- its not my original post

ms8-29 use an ic for vertical deflection, in your situation replace the components if faulty with same value you remove

Re: Help monitor Nanao MS-2932-S

I have no idea what you are doing, why are you shorting a cable?

What does it look like when a video signal is applied?

Re: Wei-Ya C31291A / samsung a68kvl74x02

i thought ok baby had rodotron 288 chassis fitted, in any case you need to read the yoke impedance and inductance to get an accurate match

Re: Time Crisis 3 needs fixing..

if you don't hear the three dings on power up then the issue is mainboard related, if dongle is missing or not seen you will get an alarm
