Akai | CT2567 | St/by only | timing constant capacitor for the standby IC is leaky. The IC is mounted on a heatsink in the middle of the board. C093 is a pair of surface mount capacitors [in parallel] connected between pins 2 and 4 of the IC. Remove these capacitors and replace them with a 220nf. | 14-09-04 |

dropout which would randomly blank out to a blue
screen in short bursts. Occasionally there would
be no sound or vision at switch-on and only the
channel change working. | Replace C933 (2,200uF 25V) whose ESR
had risen to 27 and C932 (470uF 16V) whose ESR
had risen to 48. These two capacitors sit next to each
other between the delay line and a heat sink. They
were replaced with high temperature types. | 14-09-04 |
