    Can you tell me if this is a bad cap?

    Im brand new at this capacitor thing so please bear with me.

    I have a Sanyo 26" tv and it wont power up. Only a green light on the front that will turn on/off when the power button is pressed.

    I took the back off the tv and I think what I'm looking at is a bad cap? Most of the post I see show the dome of the cap bulged but I never seen pictures with white stuff oozing out of the top.

    If I replace this cap, do you think this might solve my problem?

    Im not real electronically inclined (don't know how to test circuitry) but I have soldering tools and I can replace the cap.

    Thank you to one and all for taking time to read my post.

    Nopes, that is not oozing goo from within the capacitor. That looks very much like heat glue (usually to hold down the capacitor for easier soldering). Capacitor electrolytes are usually brownish in color...

      It is just glue to help hold it in place. Cant tell if it is good or bad.
      Try eeading a few threads in the troubleshooting tvs then if you think you might be able troubleshoot the problem post a good clear picture of the set with the back off then a picture of each board. If the set was yours give some history of how the problem
      developed say if there is sound any noise flashes smell etc.

        as selldoor says if you post some nice clear pics of each board,and the model number of the tv someone will probably be able to help you out better.

          Ah shoot. I was really hoping that was a bad cap and I would be on the road to getting it fixed. I don't have any history of the tv. Someone gave it to me that was just going to throw it away.
          I'll take some good clean shots of the boards and post em up later. Thanks guys!

            If you dont see anything obvious in these (I don't) then what would be my next step?

              Unless there is a blown cap or a big burn mark (which could be on other boards or even on the back) it normal not to be able to see anything wrong.

              Do you have a multimeter and can you use it?

              On one pic it suggests you are looking for 5v 12v and 24 v on the board so next step would be to test the voltages on the connector going from the power supply (brown board) to the Main Board (Green) and post the results

                I dont have a multimeter. And I have no clue how to use one.
                My father does. So I'll have to get it from him and then revisit this post when I get it.
                Thank you selldoor.

                  Axis Q6034-E Speed Dome cam No Power (teach me about POE)
                  by Dannyx
                  Good day folks. A friend of mine scored a couple of these Axis speed dome cams which no longer work and asked me to have a look at them, see if I can get it going. He also grabbed 2 POE injectors that used to power them. He said he tried both of them with a functional camera and they work, so the problem is most likely the cameras.

                  The problem: no power and no response from the cameras at all. The "activity" LED on the injector also blinks amber and according to the injector's manual, this means overload.

                  To cut the story short, I opened up one of the cameras...

                  Hisense 55Q9G Android reset / factory firmware reload
                  by mon2
                  Hello. Have a 55" Hisense TV that starts to load the Android OS (no backlight issues) -> reaches the app screen where you can view the assorted icons including Netflix and always crashes at the same point just after this launch. If I quickly press the cursor buttons, the cursor can navigate to the settings menu but will power off just after a few seconds of this activity. Do not believe it is power related since the crash is very accurate in the boot cycle.

                  After the OS 'crashes', the power does go off and the from white LED goes dark for about 20 seconds and then ON again....

                  Boston Acoustics HD8 – build quality impressions & DIY woofer surround repair
                  by momaka
                  Boston Acoustics fans, this thread might not be for you.
                  A few years back (~2018 time frame), I picked up a set of free JVC speakers from someone on Craigslist that no one seemed to be interested in. The guy also had a single Boston Acoustics HD8 speaker – yes, just one cabinet. He said he had no idea where he got this one from or why it's only by itself. But like the JVC speakers, it was going to get tossed at the end of that week… so I came to collect, as usual. And that's all I know about this HD8. After all, I figured why not take it and see what's inside… show it to the...

                  by abajor
                  Like title says A2141 came in with Water Damage, customer desperately wants the data.

                  The actual water ingress doesn't appear too bad it sat for a day but was very dusty internally. I have no idea why L8504 was arced there is no apparent moisture there or around the LVDS cable; however, the LVDS to screen screw studs had popped off at some point and somebody tried securing it with kapton tape.

                  I had to create a micron wire pad jumper to reconnect the south side of the L8504 since the primary pad was blasted down to the vias.

                  That said after cleaning up the...
