    Is matching inverter transformers really that necessary?

    I stumbled across this:

    Guy had a broken inverter transformer, so scavenged a random transformer... and wow, it actually works?!

    Perhaps the transformers aren't that critical!

      He did not say what the resistance on the replacement transformer was compares to the originals. It probably was a close enough match to allow it to work properly.

          Looks like he used a notebook transformer.
          I wonder how long it'll last...

              I tried inveter transformer sub (not the same P/N) in the DELL once, looks exacltly the same, but not the same impedance or the inductance. The Monitor worked for 2 weeks before it came back with blown MOSFET's.

                  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,...

                  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...

                  Original Xbox 1.0 PSU: Foxlink FTPS-0002 Rev. B. — 12 V low, 5 V high — transformer?
                  by ohren
                  Hello!

                  I'm looking at an original Xbox PSU: Foxlink ftps-0002 rev. B. The 12 V output is too low, and the 5 V output is too (?) high. Unfortunately I don't have an oscilloscope but only a DMM for diagnosis.

                  Measured voltages with no load:

                  After rectifier diodes
                  12V: 6.17 V
                  5V: 5.67 V

                  Secondary transformer pins AC measurement (really don't know if this says anything)
                  12V: 2-2.5 V
                  5V: 1.04 V


                  I also have another (working) Xbox psu from Delta. The same measures there, in order, being: 10.79,...

                  Is it possible for transformer substitution?
                  by mikey5791
                  Hi all,
                  Got this local made DC power supply (12/14V) given free as the transformer has melted. There is no marking or indication to identify what type or rating of transformer used.
                  Fyi,. I had a busted autogate mainboard with transformer with marking 13-0-13 . Is this the 13v dc type transformer?
                  My questions are
                  1. How do i test to see if the transformer is in good working condition?
                  2. Can this transformer (marking 13-0-13) be used to replace the melted transformer on the DC power supply?
                  Hope you guys understand what i was asking. My intention is...

                  Vizio E55-E1 bad backlights or bad inverter?
                  by x_orange90_x
                  I just got this tv today and it appeared to have no backlight on. After taking off the rear cover and checking again in the dark I can see that MAYBE one quadrant is lit.. But still it's quite dim. I was going to check the LEDs with my tester, and I found LED 1 and LED 2 + pins on the wire from the inverter, but I couldn't identify a ground. Nonetheless I tried using a mounting screw on the inverter board and also the chassis as ground but regardless my tester reads 300 which is what it reads when there is no voltage draw.

                  I don't know how exactly to test the inverter itself. Is it...
