    Magnavox 32ME402V/F7 No power

    Hi, I have a Magnavox 32ME402V and the tv had a blown fuse. I replaced the fuse and the set has no power. The pfc has no voltage at all. The tv is made by funai.

      Did the fuse go again? if not possibly open diodes in the bridge circuit?

        The fuse is still good but I have no voltage on the primary cap.

            The ceramic resistor <Ph>5W1R2J was bad and I changed a few diodes also.

            Does anyone know where i can find a replacement?



            Part number listed on resistor is <Ph>5W1R2J

              Digikey or mouser should have replacements. Digikey has cheaper shipping on small orders

                Re: Magnavox 32ME402V/F7 No power

                I have the same set that is making a terrible buzzing noise when it is plugged in and won't turn off. The buzzing seems to be coming from the large transformer on the power supply board. It stops buzzing when I unplug the other board with all the video inputs on it. Does anyone know what I should test? Thanks in advance.

                  Not sure if this thread still open, but having the same problem finding part:
                  ceramic resistor <Ph>5W1R2J. Search on this number at Digikey and Mouser bring up nothing. What would they be listed as? Thanks

                        I think you will be better off with the new board, for the common mode chokes to burn up that bad, the load must be really shorted out. I can see the PCB by that power resistor is burnt into carbon which is conductive so that section of the board will have to be removed which will make the board useless.
                        Did someone install a really high current rating fuse in place of the original fuse?
                        This is really crappy TV with bad power supply design.

                          I'd respect BudM's response.
                          Maybe a different problem I had, but I was able to repair two of these TVs.
                          One I used shopJimmy's repair kit below:
                          http://www.shopjimmy.com/philips-a21...2me402v-f7.htm

                          The other had a burnt spot under the ceramic resistor, and I found the kit below on e-bay. Fixed my problem:

                            I used the same repair kit off eBay for same model TV about three months ago.
                            TV still working great.

                              Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                              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.

                              Assuming...

                              Hi all!

                              I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅

                              I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

                              Hi all,

                              TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!


                              I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!

                              A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about...

                              by beetle1303
                              I gotten a Carver CM-1090 amplifier from a friend who has kept it in storage for decades. Opened it up, thick layer of dust cumulated everywhere. Vacuumed it semi-cleaned, and blown off as much as possible the remaining dust. This is a 220V version.

                              On initial powered up with nothing connected - it works with all the lights and button indicator lit up as pressed, etc. I then powered off, connected a CD player into the CD RCA input and powered it on. It seemed to work for a short while and when I turned the volume up and down to see the the VUs works, the power started to clicked off...

                              I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

                              One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...
