Re: Yamaha amp turns itself off immediately
You could start with checking the internal fuses for failure.Remember to unlug at the wall before touching any internals, replacing a blown fuse with power up and holding onto a stell chasis can be very unpleasant!! Check back with me here to go from there :)

HI , just found your post . I also have just picked up a denon DAP-2500 pre and 2 POA 4400 amps with klipsch belles, having same probs with power balance i followed some helpfull advise and deoxidized all rca jacks speaker terminals ect. also i opened the pre amp and cleand it even though it was fairly clean, i used cleaner on all switches and volume controll's . WOW I could hear it nice and clean . Next i will clean the amps. hope this works for you as this is great equpment well worth saving.
It sounds like you want to use the external amp rather than the internal one. If that is the case, just connect the output of the EQ to the input of the external amp. All you are doing is inserting the EQ between the amp stages now. Using the mx-1 rather than the internal amp is no different.
This could be as simple as a bad connection at the voltage regulator IC or blown output transistors. If you have a multimeter and some experience with electronics repair, this should be fairly straightforward.
Let me know and I'll try to walk you throught the repair.
HI SIR .THAT IS NOT BIG PROBLEM.ALL YOU HAVE TO DO MAKE SURE THAT YOUR PRE HAVE THE FLL.1 PROPERLLY EARTHED(THE GROUND FROM YOUR AMP ALSO GOES TO THE PRE )2 ASK YOUR ELECTRONIC MECHENIC TO CHECK IF THER'S NO BROKEN GROUND ON THE BOARD INSIDE.
