    is my fuse bad? Phillips 32' (pics inside)

    After a recent power outage my TV is showing no signs of life, so i decided to open it up and found this.

    Yes, that fuse is blown.

    However, it's also possible that something else in the PSU has blown too, and has caused the fuse to blow.

    Sometimes when there is a power outage, the power does not just go off cleanly. There can be voltage spikes or other crap on the line just before it goes off, and this can damage things.

    Try a new fuse, but be prepared to dig deeper if it blows again.

    Can you also upload photos of your power supply as well?

      When the fuse is blackened like that, you have something that is/are shorted out badly.
      I would trace the circuits really well and also use lamp in series with the unit you are working on.

                    Hey bud, so your saying replacing the fuse is basically useless right now as something else is wrong?
                    Sorry if i misunderstood

                      Yes, a blown fuse that's black inside like that typically means something is dead shorted on the primary side of the PSU, so replacing the fuse is probably just a waste of time at this point. You should check the primary side components for shorts first, replace anything shorted, then power up with new fuse and an inline lightbulb (see 'dim bulb tester') to make sure you got everything.

                        Thanks alot for the help everyone.

                        Is it safe to put a 4A 250v fuse into the TV instead of the original which was 4A 125V?
                        I literally cannot find a 125v ANYWHERE near me, only 250v's.
                        Also, where in the hell is the download link on the Elektrotanya site? I can't find it anywhere lol

                          Yes there is no problem with a 250V fuse. If anything, it is better.

                            On the elektrotanya website you need to WAIT untill the download link appears! Did you check for any bulged capacitors?

                              The two pdfs I upload should be good enough for troubleshooting.

                                Yeah, sometimes it takes a little while for the link to show (sometimes even 30 seconds or so) but also make sure you aren't running adblock or noscript on their website, it can interfere with the download page too.

                                  Well, of course the fuse blew when i plugged it in. Am i safe to just buy a whole new main board and replace it and it should work?

                                    Just a small point to potentially save you some headaches in finding a replacement...you're not looking for a "main board" - in TV parlance that would be the one with the video and audio connections on it.

                                      Yes, a new board will likely fix the problem, unless any other boards have been damaged
                                      as well.
                                      They don't seem to have any in stock though. Might be quicker to fix this one.

                                      In this case, the PSU and the A/V connectors are actually on the same board. ShopJimmy calls it a "Main Board". A bit silly, I suppose, but yeah...

                                        by corrize
                                        Hello, I disassembled this dead camera, and found this WTF… Two fuses soldered one above the other !
                                        I was pretty sure nobody touched it before, but that can't be from factory. There is flux, and capacitor is probably missing.
                                        The other weird thing : the fuses are « G » fuse : (0.75A – 8V), seems very low. The original fuse should be « O » : (32V 2,5A).
                                        There is « O » mark beside. All fuses have the same mark letter on main board. So, I can deduce it's a « O » fuse.
                                        And this correspond to the issus I saw : when I plug the battery, I measure the voltage dropping...

                                        Hello everyone, this topic is more of a knowledge sharing and look inside type of post, but for someone working on this model of display it might be useful. Recently I bought Acer Nitro XV273 XB MIIPRZX with busted electronic, but screen was intact, price was incredibly low, so I took a gamble and bought the unit and try to fix it. As I dug inside, I found out that my motherboard was not responding, although all voltages seemed fine. I wasn't able to find any reliable information about this monitor on the web (only some pictures of motherboards from Ebay). By some research...

                                        Help with trying to fix phone that is not charging (Pics inside)
                                        by SluggerB
                                        I have two TCL A30 phones.

                                        Old Phone: This phone worked fine for years, then stopped charging If you plugged a charger into it, the phone would make the charging sound, the phone would tell you it is charging, but the battery icon would not have the charging symbol in it and the battery would not charge.I tried new battery, same behavior.

                                        New Phone: Works fine, bought as a donor board to try and repair Old Phone

                                        My interest here is to repair Old Phone, using components parts off New Phone if needed. I am not interested in replacing Old Phone with New Phone....

                                        Samsung UE46ES8000 Blown fuse but no other signs of short
                                        by jesterace
                                        Hi I wonder if anyone might be able to steer me in the right direction. I have this Samsung UE46ES8000 TV and it went bang during use. The main fuse on the PSU board is open. I've checked every diode/mosfet/transistor I can see and nothing appears to be short to cause the fuse to go. The DC output of the bridge rectifier is not short either. I've seen online that some of these models are known for having their PFC mosfet or other mosfets shorting and blowing the fuse but i'm not seeing that here. If anyone aware of these models having any issues to cause this? I'm reluctant to just replace the...

                                        Help replacing fuse on my Mimaki CJV300-160 vinyl printer
                                        by jshhh
                                        Hi guys,

                                        I'm inexperienced with electronics repairs, I've done a little bit of soldering caps and whatnot, but i have a blown fuse on this mimaki printer I got which I have bought a replacement for.

                                        How do I remove this type of fuse (see picture)...it kinda looks like it would pull out of that bracket but it didn't come at first pull and I didn't want to brute force it incase it's soldered on there like most of the rest of the components.

                                        Anybody know how to remove this type of fuse?

                                        (The fuse is toward the bottom of the image labeled F2)...
