SOURCE: bad transformer? Sony CFS-W338 boombox

More than likely there is a voltage resultor in the circuit that will take the 24V input and convert it to 9V internally. This voltage difference is not necesarily a problem. What is the problem with the unit that is causing you to check the voltages?

A primary and secondary usually refers to a transformer. The primary side being the input side 110 AC Volt or 220 Volt AC side. Also called Source.
The Secondary being the "output to load" side 12 Volts "for example". And also called Tap (Secondary Tap)

The voltage is changed by conduction, magnetic flux, neither side touching one another. And the number of turns of wire, per side, determine the voltage. The voltage may either be a step-down or Step-up depending on its use.
An unconventional method is to have both the primary & secondary combined into a single tapped winding - which arrangement is called an autotransformer. The autotransformer does not provide isolation between primary and secondary circuits but its simplicity makes it economical and space-saving.
Imagine a single wire wrapped from the top to the bottom being the primary, and tapping in. in the middle and bottom for the secondary, so the output becomes 1/2. That would be a step-down transformer.

The actual measurement of a transformer is measured by its efficiency (Faraday Law) which is defined as a ratio of power. I hope that's sufficient, but if you want more I would buy for $2 bucks an Electricity Made Simple Book, because there are pages after pages to write about transformers, and to understand electricity in general it is helpful to understand the difference between alternating current and direct current and its magnetic field of induction and magnitude of emf.

How to measure Voltage in Transforme for Fitness Treadmill


Transformer Test Procedure:1). Make sure that transformer wire connections (CON1) to the drive board are secured. Turn unit on.2). Put multimeter to the AC voltage setting. Insert meter probes into the transformer primary (red)wires as shown. Normal reading: 110V. This shows that there is power to the transformer.3). Test transformer output by probing on secondary (output) wires: black and black, white and white,orange and orange, yellow and yellow

Transformer Test Results :1). If there is no voltage across the primary (red) wires, inspect F1 fuse on the drive board and power to the drive board. 2). If there is voltage across primary wires but none across secondary wires, the transformer is bad.Replace it.

Transformer Wire Colors Normal Voltage Value:
Red and Red 110 VAC.
Black and Black 11-13 VAC
White and White 11-13 VAC
Orange and Orange 27-29 VAC
Yellow and Yellow 10-12 VAC

Schematic malibu 8100-9120-01


http://waterheatertimer.org/Malibu-power-pack-stopped-working.html

I don't think they post schematic for the transformer
But generally, the primary coil receives 120Volt AC input from household electrical outlet
And the secondary coil produces 12Volt AC output for the low voltage lights.
The 'coil' is a coil of insulated wire wrapped around a metal core. Two coils set side by side create a transformer... when primary is energized, the secondary responds to the magnetic field caused by primary core... resulting in a current that flows on the secondary coil.
Output voltage on secondary coil is determined by the number of wraps and diameter of wire.

Some transformers offer a choice of secondary output... Kichler for example... you can select 12-13-14-15 Volt AC output
This is achieved by the way the secondary coil is wrapped.... for less voltage a wire is tapped at one point on the coil... for more voltage, a wire is tapped at another point on coil. This gives the user several wire choices to connect the lights.

No power light on my hitachi modelcx-36w cd tape radio player but power to the machine the fuse is fine


If the radio has a power transformer check there is AC voltage to the primary "fuse side", [ 2 wires ] if yes check the secondary side, if no AC voltage is present the power transformer is open at the primary. The part must be replaced.

How to identify the matching transformer terminal by means of terminal resistance? and which terminals is for input or output?


Doing a resistance test on a transformer will not give the information you require as you will read very little, if any resistance. What you need to do is an impedance check and that gets involved. If it is a normally wound transformer, not an auto transformer, you can isolate which is the primary and the secondary windings. Unless the transformer is a multi voltage input unit, the primary side will have continuity through only two terminals. The secondary could be more than two if it is a multi output voltage one. If the transformer is a step down, the primary windings will be the thinner wired windings and vice-versa. To actually test the transformer, get hold of a transformer with about a 20 vac output and try it across the two terminals you have identified as the primary windings, you should ge a proportional voltage of the actual output. eg. with 20 vac input and a 2 vac reading at the secondary, the actual output would be 11 vac if your mains voltage is 110 volts. Take care that you are using the transformer at the voltage it is designed for, otherwise it will overheat and burn out.

My 36xbr800 blinks six times then pauses then blinks six times, this is repeated......


Check the voltage input to horizontal output transformer [LOT]. Check the voltage at the collector point of the line drive transistor. If the line drive transformer primary gets open this type of fault mau occur. Also check the frequency ant the collector point of line drive transistor and the base point of line output transistor. It should be aroung 15625 Hz.
Check and replace the horizontal output transistor if needy. Replacing it is better. The horizontal output is not working or a short in secondary power supply of SMPS or lot secondary, is your problem

MY RCA 27" WILL NOT TURN ON, HAVE POWER TO THE FUSE, THE FUSE IS GOOD ALSO BUT THE DEGAUSS RELAY DOES NOT CLICK AND NO OTHER CLICKS ARE HEARD EITHER, WHAT COULD BE WRONG?


you need to check the voltage output of your power supply section.This power supply supply is a switching type power supply.there is a chopper transformer in there.its supply is a dc voltage unlike any other transformer which is AC supplied on the primary..First step.
1.Using a multitester measure the primary supply it is a DC voltage around 220v - 110 VDC
2.Measure the secondary output.The out put is AC voltage the supply for the B+ going to plyback is 115vdc the second output is 12v run through a regulator and the regulator lower the voltage to 5vdc.this 5vdc supplies the system IC and the jungle IC.this ic process the switching of the plyback transformer and the plyback transformers output supplies the voltage of the whole system including your relay in the degaussing section....once the plyback is activated the tv will now turn on...

good luck!Hope i helped you..

please rate my help..god bless!

I have a Battery Tender 12v 1.25a battery


remember secondary voltage is AC like the primary voltage, only its reduced typically 120vac primary and 12 or 18vac secondary then the ac secondary is rectified using a bridge rectifier to get the 12vdc then a filter circuit is applied to remove any electrical noise.. any way the problem is with the dc voltage side of the circuit and unless you know how to troubleshoot the circuit you will not be able to repair it. my experience says it might be a bad bridge rectifier.

I have a Pioneer SA_410 Amplifier. Has open circuit mains transformer. Could you advise what its AC secondary output voltage & current are? Regards


I have replaced many thermal fuses in power transformers. Is the primary open?? If so, cut the copper shield on the primary side of the transformer with a pair of cutters and peel back the paper insulation to reveal the thermal fuse. Replace it and everythings OK!! If the secondary is bad there's no hope, of course. Anyway, in the meantime I will research your question and post again very soon. I have several old pioneer schematics and know where to find what I need.
