Hi there.

The problem you are describing points to defective electrolityc capacitors
which form part of the start up crcuit in the power supply.
The culkprit capacitors are small and usually hide between heatsinks.
these heatsinks get very hot under normal operation and dry out
the capacitors.
Also after replacing these capacitors you may need to install a
cooling fan on the heatsinks to prevent them from getting to hot.
