Greetings to all members
Please help. My Line 6 POP XT stopped working. Only a blank yellow display appears and no channel memory numbers. All voltages are fine but the LM317 gets very hot.
The device pass an audio signal so it can be connected between the guitar and the amp but is completely non-functional. As soon as I plug it in, only a few red LEDs light up in the top row (bank ^) and nothing else works.
The three transistors Q4,5,6 do not supply voltage to the 11 pin 7 segment display. The resistance of R95 is 3.6K even though it should be 4.3K
Any advice on where I should try looking for the problem?
