Tips on fixing my Rockford P1000-1bd

jamesnail · 30th January 2010, 07:08 PM

My Rockford Fosgate P1000-1bd keep randomly cutting out and all i have to do to get it working again is hit it a bit. the thermal light doesn't come on so i opened it up and found something loose (pictures). the purple wire on top is fine as is the metal strip that runs from the top down the side onto the board, its the connection at the base of the blue cylinder that's broken. also the part with the star on it is a little bit more wobbly than the other two. I was just wondering if ther was a trick to re-soldering it, or if its fine and it is the starred part that i should worry about, either way they both look really awkward to solder.

Look under the board to see if the solder joint is cracked. Does the amp cut out if you wiggle those parts?

hey i got the board off, i assumed you couldn't because i took apart an old rockford amp a while back and it was somehow adhered to the rest of what i assume is a heat sink. yeah for easy soldering. and the joint is defenitly broken. what part of the amp should i not touch when its on. i disconnected mine for a couple days before i touched the innards so i wouldn't get electrocuted.

Get a wooden chop stick or something similar to move parts around. Don't use your fingers if you don't know what not to touch. While it's apart get magnifying glass and check the whole board over, especially hot spots.

the connector at the base of the blue thing broke off do you think i could try to stick a new one in then solder it or do i need to make a trip the store

The blue thing is a resistor, can't tell what value from the pics. What color are the stripes? Also what are the overall dimensions? That will tell you something about the wattage it needs to be.

its just under one inch tall and about a quarter inch wide with a shiny brown then two black then an orange strip one it(from top to bottom)

Orange is 3, Black is 0. The first two are the read as they are 30 and the third is the muliplier(x10). The fourth band is the tolerance, probably don't need to worry about that. So it is a 30 Ohm resistor and looks about 5 Watts. Electronic parts store should have that, Rat Shack won't.
