    Re: need help to test inverter transformer

    Thanks for the feedback, I still wonder what the difference is between the transformers. I sure like to read the inductance of the two transformer to see if they are the same.

        Are you shitting me? Wow, I messed with this set (like the rest of you) for ever. I did the same thing (bought two transformers) and had the same problem. It was incredibly maddening because before I replaced the transformers, I could turn the backlight way down and the set would still work, but after I removed the transformer, 2-5 sec. then no pic. Now I'll have to dig it up and order 1 more.

            That was what I did and it works .....and still working. It could have been something else that or just a beginner's luck or a miracle.
            hope you get the same luck and many thanks to the folks here.

                Thank you for posting all this info. I tried replacing a single transformer more than a year ago and it didn't help. I got tired of looking at it in the corner of my office, so I took another look on the internet for other people experiencing this same issue. This time I bought two replacements and made sure to match the transformers as closely as possible. Fired the set up and *fingers crossed* it's working.

                        I am going to try this myself too. I want to see if this fixes my problem too. Since the guy I bought the tv from said he only replace two of the inverters.

                            Ok replace all three of the inverter on the power inverter board. Just like the guy in this thread did. Tv works perfectly. Thanks to everyone in this thread.

                            This is the WESTINGHOUSE SK-32H540S

                            fyi. This is cheaper then buying the power supply board and was easier to get. Just incase anyone else wants to do this.

                                    did you ever fix this problem it looks like the the middle on is the only orginal transformer on the board that hasn't been switched yet i had the middle transformer on the inverter board go out I changed out the middle transformer but still i got nothing

                                        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,...

                                        by Tynan Dill
                                        I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                                        Upon bringing it home and plugging it up, it showed a standby light.

                                        I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                                        The screen seems to blackout and stay black, but with a flashlight I can see the display.

                                        With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                                        by lostone
                                        Hello, I came here after finding some similar questions asked on other monitors and hope someone here can help me get an ancient Viewsonic VP230mp (23" 4:3 LCD) back to working condition.

                                        First a little background, I have a background in computer and electrical engineering, and I'm smart enough to know I know nothing about LCD displays and how they work. For this topic I'm as green as they come.
                                        When the display is turned on the viewsonic logo displays in the uppper left for 2 seconds then the screen goes black, the power LED is green (on) and when a computer is connected...

                                        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...
