Measure the DC voltage across the B+ and ground terminals as well as across remote and ground. If you have less than 11 volts when the amp tries to power up, the amp could be shutting down due to low voltage. If the voltage remains near or above 12v, disconnect all speaker wires and signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp likely has blown output transistors.

Make sure your wifi switch is turned on. If that doesn't work, try taking out the battery of your laptop, waiting at least 10 seconds, and then rebooting. If THAT doesn't work, try system restore and take it back until before your wifi quit working.

I got my KM60 in Singapore where they use 240V. I moved back to the states and now when I turn it on the amp buzzes for a few seconds and then it has a faint static while it is on. This static...

The only change you need to make for the 120 operation should be to change the fuse to a 2 amp fuse. Faint static is typical of the electronic noise of amps... as long as it it is faint. The power supply will act differently on 120 than 240... probably takes a brief more time to get the system stable, hence the initial buzzing. As long as it performs don't worry about it.

LG WD-10160 TP. Display is showing code CL and no buttons work. I think it may be child lock but can't turn it off. The problem occurred when I turned off the machine & disconnected the water...

You are quite right, the Child Lock is engaged.

3 options for you depending on the machine:

Find the two buttons Temp and Options in the panel. Turn ON the machine, press these two buttons together for 3 seconds and that should reset it.

Or

It might have a little kids face above a lock key, inbetween the wash and rinse buttons, hold these for 3/5 seconds and it should work

Or

If it has a program selector twist dial, set the selector to off or the end of a program (If it doesn't have, don't worry) Then, unplug from the mains. Leave for 20 minutes without tampering.

Power back on and the machine should have reset

I have an Onkyo AV Receiver HT-R500 and when I turn it on, it turns on and in less than one second it turns back to standby. What could be wrong?.

Try disconnecting all the speakers and see if it does the same thing. If it doesn't, connect speakers again one at a time to find out which one of them is doing it. Make sure the speakers rating match the output of the amp.
