Re: Apple Mac G5 1.8, 20" dual, 600w PSU

Further to the above this better identifies the problem switch :-

TOP249YN Power Integrations AC/DC Converter...

My first request here and new at this.
My wife uses an an old iMac G5 which she says she cannot do without! A few days ago it had a power supply failure indicated by an audible POP! On opening the PSU I found that the switch TOP249YN had split in 2 parts with the front section spalling off from the top to about 2/3 of the way down. Could you tell me what would cause this to happen please. I have replaced the part but the board does not power up so there must be something else which has failed to cause this switch to come apart. The board fuse is intact.
I hope you are able to help,...
