martin3030 Posted March 17, 2012 Share Posted March 17, 2012 Hello wonder if anyone can help. Have picked up this and there is no output. Looking inside there is no fuse protection.Assuming it has had an overload what are the first things to be checking ? I noticed there is a thermal fuse on top of one of the heatsinks. Thanks Quote Link to comment Share on other sites More sharing options...
icastle Posted March 17, 2012 Share Posted March 17, 2012 There's at least one fuse in there - it's listed as a 20mm T5A so I'd track that down first and see if it's blown before digging too deep. As far as overload protection is concerned, relay RLA1 is designed to fail open - so if it becomes faulty you'll get no output. Quote Link to comment Share on other sites More sharing options...

Failing that it could be loads of things... it's pointless guessing. Could be a power supply failure, could be output transistors, could be something else. Unlikely to be a DIY fix. If you just want rid, I buy stuff like this as long as the price is sensible (please excuse blatant plug) Quote Link to comment Share on other sites More sharing options...
martin3030 Posted March 20, 2012 Author Share Posted March 20, 2012 Ah ok Thanks guys. Glass fuse in the carrier on the IEC socket had gone,and I replaced it but still no joy. "If you just want rid, I buy stuff like this as long as the price is sensible (please excuse blatant plug" Might be a thought but sensible could mean anything !

thepurpleblob Posted March 21, 2012 Share Posted March 21, 2012 It could Cheap enough for me to risk buying something with an undiagnosed fault, fix it, sell it and make enough for a curry out of it!! If you're interested PM me and we'll sort something out. Quote Link to comment Share on other sites More sharing options...
