Six-Trak keeps hanging on boot

Postby AmpedVoltz » Fri Jan 04, 2019 12:24 am

Hi,

anyone recognize this problem:
I have repaired several six-trak's, but this one is making the holidays hard It keeps hanging in the boot (all leds on and 00 on display). I have checked the reset-circuit and it's always +5V. So have checked the U113 and C1243 but the voltage at the negative-side of the cap drops from 5V to 0V in 1 sec... I have checked the diode 112, R124, and still drops. At the positive side of the cap there's a stable 5V...



Thanks in advance!
