Why does an electronic transformer not give any output?


Measure across the secondary of the transformer. If >20vac is present the board has the bug. Look for a fuse on it and visually inspect for a bad solder joint, if the board runs very warm solder joints can fatigue. If no voltage out of transformer you can buy a replacement using spec of 20volt secondary at 3 or 4 amps, since a 20 watt at 20 volt bulb consumes about 1 amp and there are 2 driven by the transformer.

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

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.

Identifying specs of blown transformer on PCB


I have the same problem, with the same transformer. Did you ever find the specs?

I was thinking of buying the Frigidaire board, connecting to line voltage and measure output voltage.

Television when turned on: light goes to green then flashes twice. green light goes out and red light comes on. tv will not come on.


If the Red Light Blinks twice and goes out, the TV is in Protection Mode. There are 6 voltage outputs to the lamps around the screen. If one of those outputs is missing the TV will sense that there's a problem and refuse to turn on. The predominant failure in this model are the output transformers on the Inverter board. A properly trained technician can measure the windings on each transformer and look for an open circuit, if one is found, replace that Transformer. i was given one of these sets from a friend and I replaced an output transformer ($11 w/shipping) and I now have a fully functional TV/DVD Combo. Also verify that all of the connecting cables internally are properly seated, there have been reports or the ribbon cables from the Power supply board to the main board above it not being fully inserted and it also prevented the TV from turning on. A word of caution. There are VERY High Voltages on the inverter circuit board, only persons with proper training and knowledge should attempt this repair.

Dell 20" monitor doesn't power up


I suspect Best Buy will most likely replace the monitor's entire power circuit. It's possible that you shorted out a fuse, the input transformer, or some other component in the monitor's power supply. The only way to tell for sure is to disassemble the monitor and check the circuitry visually and with a meter. This job is best left to a qualified technician.

I have a sylvania LD320SS8 32" digital/analog lcd tv witha built in dvd player


Take the Inverter Board out and check for Open windings on the 6 Transformers along the edge of the board. When you find one open, get the number off of the Transformer, Google it, buy one and replace the bad transformer. I was given one of these TV's and fixed it for $11. It's not rocket science, if you can use a DMM and a soldering Iron, you can fix this.
