I reflowed all the joints, same issue :(
I suspect le GA20 :'(
I ordered a YM2151 I'll change the one I have since I'm not able to test it and it's not expensive
I replaced all the capacitors, I think it's the lightening.
The resistances that I replaced had the right mesurements once removed.
I'll rework the joints with fresh solder and see if I get better result
How do I test the following components :
input
output
MB3730A
Pin1
Pin5
JRC 064D
Pin2/3
Pin1
MC3403
Pin6/5
Pin7
(According to the datasheets I need to test the pins listed above)
Now I have the tools, I just need someone to help me :)
