Electricity hurts
No attempt should be made to repair the power supply. The power supply should be replaced with a power supply of equal or greater wattage.
The drive appears to be a bad one. Why do you need a floppy disc drive anyways?
The only fuse located in a computer is the one in the power supply. It can be very dangerous to open a power supply without proper training. If you do not have the requisite training to repair a power supply, please do not attempt to open it. Your life isn't worth losing over a $50 hunk of metal and wires.
The concepts are very similar. I usually see "Rework" used to denote: any attempt to alter nonconforming product into conforming product. I usually see "Repair" used to denote: any attempt to restore damaged/broken product to an undamaged/unbroken state. A computer damaged by Power Surge needs repair; a computer shipped to your house minus the Power Supply needs rework.
It would be safer and to purchase a new power supply,a repaired power supply might pose a fire hazzard.
No, but they are usually not worth the trouble.
Your Goodman furnace may not be turning on due to issues with the thermostat, power supply, or a malfunction in the furnace itself. It is recommended to check the thermostat settings, ensure the power supply is working, and inspect the furnace for any visible problems. If the issue persists, contacting a professional technician for further diagnosis and repair is advisable.
It sounds like you have a power supply problem. The capacitors on the switched mode power supply have changed value or failed completely. Replace or repair the power supply section.
A computer's (PC's) power supply is a sealed unit and should be replaced as a whole - It is dangerous to try and repair the inside of that sealed unit (that is why it is sealed).
NEVER attempt to repair air bags. They are dangerous and can KILL YOU. Replace them and have them certified by the manufacturer(dealer). If it is a switch, take it to a dealer to repair. I have to add,,,,if you do attempt to repair the switch and power is applied and the air bags blow, you CANNOT DRIVE THE CAR.
If you are supplying power in vehicle or base station (using a AM-7239/VAA) it is suggested that 24Volts & 5Amps. The same type of power supply could be used in a repair shop.
Replacing it altogether. If you are not properly trained, you could very easily be killed if you attempt to open a power supply. Purchasing a new power supply will usually cost less than $60, ensure that the problem is fixed, and probably save your life.
