chile Posted June 20, 2012 Share Posted June 20, 2012 is the metal filament always broken when a fuse is bust? one of me decks isnt turning on anymore. I replaced the plug fuse with the working deck but had no luck so its not a plug issue. i opened the deck and theres two fuses in there and im not sure if its worth hunting those specific fuses down as the metal filament still appears to be in tact. heres a pic: Quote Link to comment Share on other sites More sharing options...
Guest Symatic Posted June 20, 2012 Share Posted June 20, 2012 get a multi meter and test all the fuses. they dont always break visibly 1 Quote Link to comment Share on other sites More sharing options...
Steve Posted June 20, 2012 Share Posted June 20, 2012 Can you borrow a multimeter off someone? Take the 2 prongs and touch one to each end of the fuse and it'll tell you if it's still making a circuit. Usually if a fuse is dead the filament is burned out though. When it stopped working, did you notice a burning smell? If so, the PSU may have burned out. It may also be a faulty power switch. I remember someone on here (Dub-Se7en maybe) having a similar issue with a Vestax PDX-2000 and it was caused by a broken power switch.

Steve Posted June 20, 2012 Share Posted June 20, 2012 Obviously, make sure you unplug it from the wall before you start messing with the multimeter. Burned out board = bad, but burned out chile = worse! Also, scour the board for any signs of burned out components or other fuses that may have popped. Check all connections and plugs. If you've thoroughly checked everything and there are no signs of burned out components, burn marks on any of the boards, or blown fuses, then you could try desoldering the wires from the switch and temporarily bridging them. If the deck powers on, you can source a replacement switch. I would not advise running the deck like that though - just do it as a test - because if something caused the switch to blow out then bridging the wires may not be a good idea long term. It's a reasonably common problem with old PDX decks and it's usually just that the switch is knackered and needs replacing, but it's best not to take any risks IMO.

chile Posted June 20, 2012 Author Share Posted June 20, 2012 just got back and it was the power switch that was the cause. the maplin guys tested everything to find the cause and replaced the switch for a total of 3 quid 50. chuffed Quote Link to comment Share on other sites More sharing options...
Chris Posted June 20, 2012 Share Posted June 20, 2012 that was nice of them, i always find maplin is full of blokes who haven't the foggiest idea what they're doing - there's one guy that really knows his onions in leicester though. Quote Link to comment Share on other sites More sharing options...
chile Posted June 20, 2012 Author Share Posted June 20, 2012 yeah i was apparently lucky as the only three people they had in the shop then were all specialists.. a computer tech, an electrician and a mac guy, but alot of the time they mentioned there arent any specialists in and instead you just get people that know how to use the cash register and thats it.

scottie(the)goonie Posted June 20, 2012 Share Posted June 20, 2012 get a multi meter and test all the fuses. they dont always break visibly yea the "continuity" check eliminates the guesswork Quote Link to comment Share on other sites More sharing options...
djlotus Posted June 21, 2012 Share Posted June 21, 2012 For future reference, a blown fuse will not have the small "line" running through it. Like a light bulb, the fillament breaks when exposed to too much current. As said before a simple continuity test is the easiest way to check.
