Re: FRG-7 lock light problem


 

Hi, just go through the area with a soldering iron and reflow all the connections. The main components that control the Led are Q110 and Q111, plus the surrounding resistors and capacitors. I assume you have a schematic diagram.?

Thanks for the explanation.?

Last night I tested the voltage at the joint of the led wire. It was 1.45v when the led was working (fist time starting the radio after letting it sit for a few hours) then it dropped slowly all the way to 0v.

I tried to trace the what the led is connected to on the circuit board but it got a little bit confusing.

If I post a high resolution picture of the circuit board, will you be able to spot a bad joint??
