r301 is reading 129 and 144 in the back
new IC2 , IC3, IC4

solder pads r89 and r101 redone R103 new

cold solder reflowed and been reading for long time

help !
 
what'd you fix the pads with? I got a redemption game (ICE Wheel of Fortune) where one of the pads on the bridge rectifier came off. requires a shitload of heat to set one of those things, so I must have fucked up pretty badly to make that thing come off.

sorry to be a thread derailer. :(
 
Double check the yoke header pins and maybe measure the yoke resistance as well.
(just to eliminate those things anyways)
 
New caps?

Vertical output IC replaced with the correct one?

Capacitor C51 replaced?

yes and yes and yes thanks

how do i test C37 and C38 - just going to replace them but im just curious how do i know if they are good/bad ?
my ESR meter cant see them(even the new ones) and my DMM does nothing with the two leads on either end, i guess thats good but im still not sure

still struggling

thanks Kevin / will look again mecha187
