Wavy lines on mac classic CRT

[chungus]

Hi,

I got a dead mac classic, so I recapped it (revision p/n 630-0560). I also replaced the TDA4605, optoisolator, and diodes DP3/DP4 according to the dead mac scrolls. I managed to get the CRT working.

However now there's wavy lines on the CRT on power on, and when it turns on it makes whup-wup-wup sound. nothing else happens.

What else do I need to do to get it working?

So you recapped both the analog board and logic board, then? Hmm.

How are your voltages looking? Did you touch up the solder on the back side of the AB particularly at plug and wire connectors? Solder joints are often cracked in those areas.
