Problem with philips streamium 7500 turns on but screen just flashes
Modern electronics use a switch mode which has an oscillator.
When they fail, they tend to work fine until the power is removed and just don't power up.
There are components called capacitors which dry out and age which is most likely what has happened to your unit as they stop the oscillator starting up.
Its relatively easy for qualified engineers to find and fix these faults but sorry to say not something easy for someone without knowledge of smpsu's.
These power supplies can be dangerous to work on and can even store high voltages after being off for a while.
