Welcome to your forum Gustavos! while your ambition & effort to save money is admiirable unless you know how to get a schematic diagram of this model that tells you where to make the repair & you know your way around either a soldering iron or a welder it's better to get a replacement which depending on the age might be better
hope this both enlighens & behooves you
good luck nevertheless
if this doesn't solve your problem or if there's anything else
please don't hesitate to come back
