    Bush LCD37TV016HD Rant

    I just fixed this TV. Two bad CapXon 1000u 10V (replaced with Panasonic FC) and one 1000u 35V (not yet replaced will do shortly.) Before, it would not power on - now it will power on fine with no issues.

    The power supply is a pretty good layout, apart from a few things. One thing is the fact that several electrolytic capacitors have been placed under the heatsink. That will quickly kill the capacitors. That's bad, but anyway... After choosing a power supply with heatsinks pointing vertically, to allow for confection cooling, they then place the power supply in a cage, preventing proper ventilation!!

    The power supply is full of CapXon, we all know about them...

    Whoever OEM'd this for Bush were complete incompetent idiots.

      Okay, I just fixed this TV completely. New 1000u/35V Chemicon KY.

      Anyway, the design of this thing really takes the biscuit (to put it politely.) It turns out all the electronics slide out in a tray and a connector, much like a parallel LPT port, connects to the rest of the chassis.

      The TV worked great for a while, but it began to give problems. It wasn't doing anything - I thought I had broken something. No, all I had done was disconnect the connector just slightly. I only discovered this after I pushed the tray in slightly, and the TV worked perfectly.

      Assembled it and the connector is actually pushed in by the case itself. WTF???

      Now it works.

      Another TV saved from the dump.

              Possibly, what tests have you done?

                  Nothing so far, just going to open it up now.

                          How do I do that?

                                  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...

                                  Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
                                  by sam_sam_sam
                                  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...

                                  by sam_sam_sam
                                  I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails

                                  I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time...

                                  Hi, Can we use SMPS Bench Power Supply for Laptop troubleshooting?
                                  by shamsudeen
                                  Hi all, I just need to know that, can i use SMPS type power supply to test and short circuit detection on a laptop motherboard?
                                  I saw 95% of repair guys are using only Linear bench power supply. linear bench power supply is pricy, thats why i planned to get one SMPS supply.

                                  i know that in linear power supply the noise will be very low comparing to SMPS supply....

                                  Definitive technology SC 2000 subwoofer amp's power supply clicking and popping
                                  by JimBanville
                                  The sub developed a constant popping every couple seconds from woofer and power LED flickering with nothing but wall AC connected. Connecting an audio cable didn't change anything. It doesn't play but a second or two of audio in between the pops.
                                  Opened it up and discovered the power supply is making a faint clicking or ticking sound.
                                  I measured the amp's output to the woofer and it pulses up to 50mv DC to be driver. The pulses coincide with the power supply ticking/clicking.
                                  I measured the power supply output going to the amp board and it too has this pulsing. Voltage cycles...
