mikebass84 Posted April 17, 2014 Posted April 17, 2014 I lent my head to a friend over the weekend as his has been stolen. Everything worked fine but now I've got it home it's not working. II'm getting no input lights or any output. Took it to practice tonight to kmake sure it wasn't the cab or leads and same problem. AAny ideas? Quote
DarkHeart Posted April 18, 2014 Posted April 18, 2014 I had a similar problem with my eb180 combo, it turned out to be one of the leads had fallen off the power socket at the back of the amp, reattached it and its been fine since, alternatively it could have blown a fuse as you say there are no lights so its electrical not a cab or lead. this is what was wrong with mine.

mikebass84 Posted April 18, 2014 Author Posted April 18, 2014 I have a tech friend of mine coming to have a look at it today. Hopefully it's something small like a fuse or just a loose cable Quote
mikebass84 Posted April 21, 2014 Author Posted April 21, 2014 My tech friend had a look and couldn't find anything wrong with it. Said it worked as soon as he plugged it in. Got it home and it is indeed working fine. Totally confused Quote
mikebass84 Posted April 24, 2014 Author Posted April 24, 2014 Ok so it was working fine. But then stopped working but this time when I turn the output knob I get an odd crackle and the speakers move. I opened the head up aand one of the fuses had blown so I bought some new ones and changed both. Still doing the same thing. All the cable are attached and nothing looks blown. Help! Quote
mikebass84 Posted April 28, 2014 Author Posted April 28, 2014 So I decided to take a closer look at the main board. One of the resistors seems to have a scorch mark on it. Would that be the reason it's playing up? [IMG]http://i.imgur.com/X38v8SE.jpg[/IMG] Quote
MoonBassAlpha Posted May 4, 2014 Posted May 4, 2014 I'd check the underside of the circuit board and see if any of the solder joints to the larger components has fractured. These will be the parts most likely to vibrate and break a join,or even a track. A rapid disconnect/reconnect at the output can cause the fuse to blow due to the inductive effect of the speakers. Often, a quick dab with a soldering iron is all that's needed. Quote
mikebass84 Posted May 9, 2014 Author Posted May 9, 2014 Ended up taking it to get repaired. Only cost me £30. I think he said some of the power transistors (?) had blown and needed to be replaced. All I know is it works again Quote
