Hello
Got this speaker from a friend , defective. Power led comes on and off , in a loop.
Disassembled, got the board out, and after a bit of measuring I found a low resistance on a 5v6 line. With a bit of current I found a transistor heating up on that line (labeled T1 and 113 as on pic).
After removing this guy, I got a value of 0.7 in diode mode on that 5v6 line, which before had 0.02 or something like that.
I tested powering it up without the IC, and the speaker turns on and stays on, and works fine
Still, I need to replace this transistor.
I found a schematic, and also there I see it as T1, and with reference of 113, which is a bit confusing to identify...
On the IC itself, I have 3 dots on top and GS O, bit hard to take in pic.
Can someone help me getting this part right?
Thank you

I guess pictures are starting to reappear too!
