Hi after seeing your post i try to identify if my problem is the same .

Can you explain if there is a components at the place you solder ? Mine looks like none. But before solder i just want to make sure.

So you make a bridge between the two solder point ?

thanks

The one i fixed had broke the resistor clean off, so i just soldered between the 2 points. Try to get a magnifier to see closely if it is missing.

Hi thanks for your answer. I take a magnifier and see a gap between two pin next to the screw hole.

is this correct or is this the resistor behind this two pin ?

I will try to take a photo but it's not easy...

Thanks a lot..

It is the one closest to the screw hole. So it is number 1.
