Broken Anode on a Mac SE Analog Board! Please Help!!!


Recommended Posts

So I might be SOL here, but I'm going to ask anyway (and hope for a miracle).  In an attempt to replace the fan in my SE, I detached the anode from the CRT so I could work on the board.  Everything went well.  The new fan works.  However, when I was reattaching the CRT, the tip from one of the prongs snapped off.  I only tested the for a second to see if it might still work but only got a single dot in the middle of the screen.  Obviously, I turned it off after that, and I'm not messing with it until I figure out a workable fix.  My question is can I remove and replace the flyback transformer on the board with a new one, or do I just need to suck it up and replace the board?

 

If I can replace the transformer, then what is the part number I should be looking for, or what would make a suitable modern replacement?

A dot in the middle of the screen usually means the deflection coil is not plugged into the analog board. Try fixing that first.

THANK YOU SO MUCH!!!!  That did work.  Now I feel like bit of an idiot for overlooking something so obvious.  

 

However, that little bit did break off.  Is that something I should be worried about?  Could the anode come loose or cause damage?  Or am I OK now, and can I finally sit back and enjoy my first (and favorite) Mac?

I did the same last weekend, the connector tends to be a bit hidden out of sight, so it's easily overlooked.

 

It depends, I'd say. Try and see how sturdily it's still attached, or if it's easily knocked out of place. If it stays in place relatively securely, I wouldn't worry too much unless the Mac is often transported. If it does fall off easily, then maybe glueing it down with something secure, but easy to remove, like silicone glue or hot glue, might be a good idea. A few dots should do, and it should be relatively easily removable if the anode needs to be taken off for servicing again.

It seems pretty secure (in that it doesn't come off unless I take it off), but I do move it on occasion.  So a few dots of hot glue sounds good for peace of mind if nothing else.  Thanks again.  :-)
