My synth has died. When I switch on the power al the LED's come on and stay on. HELP somebody.

Sorry to hear that...
It's a terrible feeling when that happens, I've been down that road before!
You can try www.winecountrysequential.com (I think thats the address) for parts or service. Be very careful about taking your synth to local service depts that may not have experience in repairing your particular synth.

Good luck!
