Receiver suddenly stopped working for no apparent reason. Standby light goes off (as it should) when power button is pressed, then turns back on after a few seconds. Unit purchased from third party through Amazon Dec-2004 and has been used very infrequently in the last year and three months. The unit has a three year warranty, so now I'm trying to locate the nearest authorized service center via their website at <www.sherwoodusa.com> to have it repaired. Guess you get what you pay for...
