Team jesan 3100euro uk Homebase help needed

Hi

I bought a team 3100uk Homebase not working

I looked inside and I have seen 4 wires that have came off

1 x white wire which is soldered onto the top of a tuning can

1x black wire thicker than the rest which is connected under the board

1 x white wire from the rear of the radio located behind the coax connector and next to r1 position

1 x purple wire from the eprom on it’s side


Any help appreciated
