got a vertical collapse problem with this monitor. I've recapped the monitor and changed R255 (150ohm 1/2W) because it was slightly burnt but still gives me a vertical collapse after a couple of hours. So I'm leaving IC103 (TDA1675) out the picture since it does seem to work but I have no way of testing it and TP31 does have +25dc volts. Does anyone know what other parts or known failures could be giving me this vertical collapse? I've also checked R177 and the VR's on remote board already.
