If you're trying to just plug in the wall power cablem without connecting the motherboard it will not work. Switching power supplies need to detect a load (device) otherwise they will not put out power. Safety feature.....

D-link router (with 1 antenna and no modem) that has no power and no LEDs lit. the outlet still works to charge a cellphone. how do we fix the router?


Possibly the powersupply for the router is dead. Find another powersupply with same voltage output to try OR test the output tip with a meter. If the power supply does work then your router is dead. Replace it. If there is no power (5 volts or 12 volts etc) coming from the tip of the power supply adaptor then replace the adaptor / power supply.

I have a KDL52s5100 it is not working(no lights, dose not t turn on) due to a thunderstorm. I have bought 2 powersupply board and a new main board and still nothing turns on no even a light.. please help....


make sure that all the voltages in the power supply output are present before connecting to the control motherboard. also confirm that the cables supplying the voltages to the motherboard are all matching e.g do not make a mistake to connect the 3.3v cable to the 12v terninal. just be cautios and your system will power up

I have an old SPX90 Digial Reverb with a dead powersupply. The part number on the board is VA81400. Is this part number correct? Is the part still available? We tried ordering it from the Yahama dealer,...


Any power supply will do as long as it has the same specs as the dead one, which will be:

Input : x Volts AC
Output: x Volts AC or DC
Watts: x
Amps: in millamps
Polarity: (for power supply with DC output only) Center pin = plus or Center pin = minus

You should be able to find the matching transformer/adapter/power supply at Radio Shack.

More info, let me know.

Charlie

P.S. The power supply you received may be the correct one -- check to see if the specs match the old one.

Siren digital picture frame wont turn on


I had to fix my boss's digital photo frame today and it looks like it was a power supply issue. All i did to fix it was connect a usb cable AND the powersupply. The frame turned on right away. The power supply may not be able to output enough juice for powering up the frame.
