    Exact same component failed. Opened up amplifier and used multimeter to verify that 240V AC goes into the transformer and nothing comes out. No information other than part number (NC-V4282TA1, 3200-428201-400) written on transformer.

With out make and model, I can not supply parts information. Please update this with that info. Also, depending upon the age of the unit, parts may not be available. Are you sure that the problem is the transformer? This part is rare to fail.

Will not heat water, cavity light and touch panel are working ok


It sounds like the magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.

YOUR SAFETY IS PARAMOUNT

This is a job for a professional but if you are safety clued up, here's instruction.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 or moving coil meter on high resistance range for short circuit, (DVM's won't show the fault!), the capacitor can fail and go short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.



Magnetron used with no load.

It sounds like the magnetron may have either failed or is not being supplied with the extremely high voltage required to run it. Using the microwave with nowhere for the energy to go results in magnetron meltdown!
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.

The magnetron may be all that is required but the diode pack may also have failed. These components are Safety Critical Items and MUST be replaced with identical units for continued safety.

Spare parts are available through the Manufacturers Authorized Agent. Go online to find a supplier near you.

Hope that helps.

A Marshall 100w amp that lacks heater voltage on all tubes


Yes, it is the power transformer that has failed. If you are comfortable with replacing it then do so just be careful. If you could though I would be careful and check to see what power you are getting at the transformer just to make sure

Sony 36" Trinitron


The power supply section is having trouble.
Common possibilities are:
- High-voltage section (flyback transformer) has failed
(happens sooner or later, about 8 years typical))
- CRT tube has failed overloading the supply
- Power surge has popped the power input circuit.
(Fuse, rectifier diodes, turn-on relay etc)
- One of a hundred of electrolytic capacitors has failed short overloading the supply. They dry out with age, are cheap to replace, but hard to find which one it is.
- Or any of many other possibilities.

In short, you need a experianced tech to troubleshoot this.
