    Bush 32TV016HD issues

    I have a Bush LCD 32TV016HD, which at power on does nothing, no lights at all,have at least 300 v dc on the filter capacitor, but nothing else where. have been trying to get a diagram of the power board TC18607A1, with no luck. Any help would be apprecaited.

      Re: Bush 32TV016HD issues

      Common issue on these is shorted 5VSTBY diode.
      Pictures?
      Is this a VESTEL or PROVIEW build? Pictures will reveal that if you are unsure.

            How about pictures? Maybe someone here or myself will recognise it.

              have tried several times to send a picture but it will not up load. I was reading a thread and the TV had the same problem,so I downloaded the power board pictures and it is the same power board, but I cannot find the thread again.

                          So, can you see any voltages on the power connector going to the main board, or is it completely dead?

                            To add to that: is there any 5v standby? I know you said you had no voltages, but do you get 0v on the 5v standby, or say 2 or 3 volts?

                            That pic of the connector is very good! BUT, there are more than one of them on the PSU. Can you get us a picture for each of those other connectors?

                                    have you still got voltage across the main capacitor? can you post pictures of the underside of the board as maybe some blown smds.

                                          Issues in PWM circuit with LC filter to drive Peltier
                                          by vrasp
                                          Hi,

                                          I've been trying to build a Peltier circuit that I can control with arduino and create cooling ramps. I've never built a circuit before and only have a basic knowledge of electronics.

                                          I've been researching how to do this and attempted to build it. My circuit is basically a PWM signal sent to a motor driver with an LC filter to smoothen the signal. Since very low temperatures are required, I added another Peltier on top of the first one. The top Peltier needs to be driven at a lower voltage to limit the amount of heat produced and effectively lower the temperature....

                                          Help with Bush Tv (Vestel 17mb95m Mainboard)
                                          by FlailingEngineer
                                          Hi, I was recently given a Bush Smart TV by a friend and the main board seems to be hanging on by a thread.

                                          Before we get to that, my first obstacle was figuring out the model number since the back sticker has gone for a walk. Upon taking off the back case, I noticed the following Vestel parts, 17MB95m mainboard, 17IPS71 (what I'd assume is power supply) and a VES420UNVL-3D-S02 display panel. After doing some research I think the TV I have is a Bush ELED42240FHDCNTD3D, based on the matching image here (https://www.manualslib.com/manual/11...td3d.html#manu...

                                          Hi, trying to troubleshoot some problems with this laptop I just finished repairing which had power issues (Burnt Buck converter - SY8883DFC shorted to ground).

                                          After repairing the above issue, I realized the following remaining problem,
                                          Sound only comes from bottom speakers, top palmrest speakers don't work. Neither does the headphone jack (static/buzzing).

                                          Sometimes, the computer will boot up and the sound will be working fine. However, if I run intensive programs and the computer...

                                          Lenovo IdeaPad Gaming 3 15ACH - Ideapad 3 well known solder joint issues
                                          by Nagyesz
                                          I have a Lenovo IdeaPad Gaming 3 15ACH, which has started exhibiting the well-known issues of the Lenovo IdeaPad 3.

                                          All stress tests run perfectly, and there are no performance issues. However, the solder joints are almost certainly starting to fail. If the top two screws on the back are not screwed in, moving the screen results in a BSOD or, in some cases, a slight artifact and freeze. This is a 2023 notebook..

                                          How can I extend its lifespan? Could reflow help?

                                          It has ryzen 5 5500h, rtx 2050, no soldered ram.

                                          Example of the artifacts:
