I've just taken my son's PS2 apart when it stopped working (no power - no signs of life).
Found that the cable connecting the standby button to the box had come loose - was able to reconnect and we now have power.
However when booting up, there is no output going to the TV - not even a flicker. The CD spins, the fan comes on, everything seems to behave as normal but no screen output.
Fairly sure its not the AV cable.
Anyone able to help.
A despearate dad !!!
