Question about Gateway (6500683) 160-Watt Power Supply

1 Answer

Gateway Profile 4 PS Have 20 bad units that need fixing!

Thought it was just a blown fuse, but no. Some have ramping problems that go from almost zero to 12 volts on a digital meter, and then drop back down repeatedly (power LED goes dim and then bright). Some have no DC output, and I had also replaced a few N channel MOSFETs that were burned out (soot evident) and attached to a thick heat sink. After replacing some of the smaller TO220 sized chips, still no DC. These are all mostly Delta ADP180 power modules like the photo. Some have a power LED and some don't. Even invested in some hard to find MOSFETS (from ST Microdevices) for these, in hopes that just replacing the chips would fix some of the problems. I do hear a 'click' (like a spark sound) when I plug in an AC cord so I know power is going in, but it never gets to the DC out end.

In today's times most people don't service power supplies because they can catch on fire at anytime and with the litigious society we live in today, it isn't worth it to do it.

The best way to fix the problem is to get a new one.

Microwave Dead

Having 20 year experience fixing microwaves i know that when the fuse goes that if you can't find a melted wire or overheated components on the circuit board that the high voltage capacitor at the back needs to be replaced. Sometimes you have to replace the magnetron too. You can replace the door switches if you like, microswitches are inexpensive but would only be bad if arced inside so bad that you read over 1 ohm.

Heater does not blow air

zero air flow.
#1 is bad fuse fan.
if it fails on high , the fuse is blown,
replace it or test it with a an ohm meter .
DMM meter. select, ohms Rx2 (low range)
zero ohms is good, infinity is bad.
a 100% accurate test. every time.

KitchenAid KCMS1555RSS - display completely blank and does not function. Is it worth fixing?

i would try and see if the fuse is blown in unit ... normally behind control panel there is a in line 20 amp fuse that may have blown.... if the unit makes noises when you touch the buttons but no display then you have a bad control board assembly

Before you buy anything else try it with another monitor. Obviously if the other monitor works then its not your motherboard its your monitor. Update video drivers to ensure you have the latest.

VX924 Blown Fuse

What are the symptoms? How do you know the fuse was blown on the monitor you bought? The fuse on vx924 is soldered onto the circuit board. If you have any symptoms that require power its probably not the fuse. The back lighting on this unit has a problem. Three 25v 470uf caps on the circuit board are underrated and have a tendency to go bad. Replace them with 35v 470uf caps.

Unknown model not working could be a bunch of things!
does the unit have power?? fuse(s) ok?? turn on voltage present(12v)?? Any leds?? Unit ever get wet?? Any lites?? smoke get out?? was it, did it get real hot??
I have worked on a few with various problems, no common problems. Some of the things I have seen; Level adj pot was smashed in, Shorted fets , + burnt gate drive resistors in the ps section + blown runs, bad connections, shorted outputs, corrosion from beer leakage, bad electrolytic caps, leaking caps ate up the copper runs, metal bars used to hold down fets and outputs came loose, parts over heated and shorted.
Open up and look around, burnt resistors, leaking caps, puffed up caps, black marks, are all helpful signs.
These amps typically use FETs in the power supply(+/- 25-50v) and regular transistors for the outputs. Test all heatsinked parts for shorts. Carefully remove metal bars holding down heatsinked parts, keep track of where the heat sink insulators go, remove pcb and inspect runs. Repair and bench test with a power supply that has an amp meter. With out any input, unit should only use a few amps after initial 5-15amps to get the PS fired up. Then test across speaker outputs for any DC voltage. Anything over 1v, (should be very close to zero) amp needs some more work.
Good luck!
