got this recently with no sound. just put new capacitors in. its a squawk and talk 61B
test points 2 and 4 are correct, 3 is a little high, 13.5 V.
i get 5 LED flashes when powered on. if i press test button on board, speech samples play, and volume knob works.
jumpers are correct. i also found continuity between sound board and wires to MPU
Still no sound at all during gameplay
any hints?
edit: i found conflicting info about jumpers DD and N, mine were connected so i disconnected them. Now when i press the test button, no speech samples play. One or both of those jumpers are needed i assume.
also, with volume at high on knob on door, and both pots at high, there is an audible speaker hum. there is no distant/quiet sfx tho.
