Title: Soldering problem on Wells board....
Post by: mamerocks87 on January 18, 2006, 11:54:12 am: I am currently looking for bad solder joints on my 27in Wells board and I have found some. It seems that alot are beaded up and not really attatched to the board. The little silver base (that is attatched to the boards itself) that you solder on is not there. So i can not solder onto some of these joints. Here is a picture to show you what I mean. Please give me advice on what I can do.

So what you are saying is that you would solder the capicitor's leg to the actual track of the circuit. Is that correct? How would i do this?

I have both syncs wired up to the hsync (comp)

See it was working fine, then it suddenly went out like this. Any clues to where I could start?
