[QUOTE="2cvbloke, post: 1047969, member: 199791"] My thoughts are that as most OEM power supplies are ultrasonically welded shut, the only way to open them is to use a hot knife tool (basically a lower temperature soldering iron with a flat blade tip), of course this leaves the issue of reassembling the casing in an adequate fashion, such as using glue or solvent welding to re-join the two halves... I've no experience of cutting open such supplies with the intent of repair, for me it'd be a one-shot deal just to see what went bang before it went in the bin... :) [/QUOTE]
