    Just hit the buy now and the transformer spec will come up.
    http://lcdparts.net/TransformerDetai...ProductID=2732

    You can also remove the transformer to see how the windings are arrange.
    If you have more than one transformer on the board then you can compare the resistance reading. When you work on many of them you will know how the transformer windings are arranged.
    BTW, are you asking about inverter transformer for LCD TV or Flyback transformer for CRT.
    Thanks will try it out and will let you know.

    May I ask you what you think of this:

    I am asking about LCD and any other sort of transformer which you can find in a monitor, tv and electronic devices.

    i use this to test transformers.
    the pdf has the schematics to make one.

    Help - how to test an inverter transformer

    Hi Guys,

    I have been wondering how could I learn to test Inverter transformers and any other sort of transformers. I have been googling around and tried to understand the below webpage:
    http://www.jestineyong.com/test-lcd-...r-transformer/

    Can anyone please assist and teach me how to test them please?

    Thanks,
    Matt

    Sony KDL-46BX450 Inverter Troubleshoot Logic
    by caseyjay_48
    I am currently on a troubleshoot of 46” Sony KDL-46BX450 tv. I came back from Washington to Texas on medical emergency and had to leave all my tools up there. All I have is a couple of screwdrivers and a dvm. I wish to ask the community a troubleshooting question. Please forgive stupid questions as meds I am taking produce brain fog.
    I have well maintained Sony KDL-46BX450. It went black one day. After turn-on, I get solid green light and Sony logo in screen center for about 1-2 seconds, then black. No blinking LEDs, no hissing. Flashlight test shows screen characters dimly viewable,...

    How Can I test PWM DM0365R?
    by chth96
    Hello
    I have power adaptor(220V/input, 12V 1.2A/output) which has symptom of fluctuating output DC voltage between 11.5V-12.2V.
    So I opened its plastic case and when switched it on, I heard constant tik tik sound from inside its PCB.
    I measured DC voltage between negative and positive pin of the largest capacitor(400v 10uf) and it was measured contant 300V.
    I also measured ESR value of all capacitors and I noticed that one of capacitor(KMG 16v 470uf), which located in the secondary side, have high ESR value(10 ohm),So I replaced it with same specification NXH capacitor....

    Samsung LN40C630K1F LCD TV No Backlights and Flashlight Test Fail
    by signal.quest
    Hi all,

    I have been working on a Samsung LN40C630K1F LCD TV. On power up the backlights only briefly light up when first powered on then they go out (2 seconds to black). The flashlight test also fails. The sound works fine. Please see attached pics.

    I have researched the forums a lot. I have watched the videos of trying to locate the bad CCFL or transformer and bypassing. I can't find any evidence of a bad transformer/CCFL. I verified I get 376V from the big caps to the fuse. I have used a small/cheap oscilloscope and it looks like the MOSFETs on the inverter...

    is it ok to replace a dual output transformer with two single output transformers?
    by amelbye
    Hi, some prestory: I was repairing an amplifier - a "Phil Jones Bass". It had some bad capacitors an a faulty power switch. Easy job. However upon putting it back together I screwed up. The connector from the 15V-0V-15V from the transformer is identical to the audio ouput from the preamp board to the poweramp board. I ended up putting +-15VAC into the preamp outputs frying some traces on the circuit board along with the power transformer The transformer is shorted. It blows the fuse immediately even with no load on the secondary.

    Now that's a challenge - luckily...
