	Yamaha SPx900 – repair log

	-- FAULT --

	Noted fault, "BATTERY LOW" warning on switch on, not passing audio.

	Inspection revealed that a new battery was in place (reading 3.1v) and at some point, the 4 electrolytic capacitors on the PSU board had been replaced as well as the reservoir capacitor C163 across the 5v rail on the main board.

	The display was very faint, and the LED backlight very dim. The display was original.


	a "repair " note for a failed to repair one. I even worked out the schematic

	but could not find the reason for the slightly linear ps characteristic, not

	full switching, and then thermal runaway. Even tried rewinding the secondary

	of a generic smps toroid and could get it reliably working but only with a

	fan. There was some shorted turns in the original, presumably due to excess

	My Apple devices started stating "incorrect password" for my network, even though they had conncted previously.

	So how to fix Unifi network "incorrect password" error on iPhone, iPod, iPad and Macbook pro?

	The reason for the error is the WiFi management done on iOS devices.

	The default settings for the Unifi AP range are not compatible with iOS 11 and 12 and OSX High Sierra (and maybe more).

	The reason for the error is the "DTIM Mode" (beacon timing) setting for power saving.
