Not the best news in the world, but thanks for letting me know.
I just hope that if it is the power supply that has gone, that it's not too expensive to replace.
I'm quite surprised about that Samsung's site doesn't offer any troubleshooting tips of their own, nor a single link to a uk based tech support for such systems.
Actually one more thing, if there was a power supply issue, would the LED's still be blinking when the power is turned on? I had a brief look under the casing to see if there was any obvious damage earlier, and the lights are still active.
Once again I really appreciate your help.
