Help fixing my old DT770 Pro's

post #1 of 4
Thread Starter 
Hi,

About two years ago, I somehow "silented" my left driver, I wasn't experienced enough in soldering to begin to repair the driver, and I even thought the driver where dead at that time...
But I've been trying to fix the driver by re-soldering the cable to the driver, unfortunately I didn't know how the cable should be soldering back on, so I began to search, but with no luck, as I found nothing usefull, only blurry pics, and pics of the DT880's which doesn't look anything like the DT770 driver...
But I tried to solder the cables on, with a old Weller, with a half broken tip (therefor the bad connections) but the driver still didn't work, see my pic..
Anything wrong with the connections? Anything that should be moved to another pin?


Regards
Jacob

That's a cold solder joint and the cable looks enameled (thin coat that prevents contact of wire to driver). Sure it's not the connector that's broken?

I have no idea if the connector is broken, what I do know is that when I first tested with my multimeter, it crackling noises from the driver, but after I began to solder, it suddenly stopped (which I suppose is a bad thing, right?) And yeah the solder joints are crap gonna buy a new soldering iron soon... any recommendations on a cheap new one?
EDIT: Oh yeah and before I forget, when I soldered on the connectors, they began to bow downwards, as if they became to hot, and meltet through something

Look on the underside of the connector, you will see a VERY thin wire, make sure it is still connected.

Good cheap irons : Weller SP23 & SP25, Hakko Dash

Make sure to first tin the wires and get the solder to stick to the wire before soldering it to the driver.
