    Re: bush DLED32165HD startup issue

    Have you checked if the PSU works first?
    Vestel sets don't use error codes (afaik)

        Tom how would i go about checking this PSU as the pins overlap each other ?

          Carefully is how... :p

          You could use test hooks if you have some really small ones, or take the boards out of the set and probe the back side.

          Another option would be to solder wires on the underside and connect to those.

              Hard to say. Did you disconnect anything?

              Also, make sure you don't let the boards short out on anything.

                    What are you using for the GND ref for your meter? The Secondary side circuit GND is connected to the chassis when the boards are mounted to the Chassis.

                      for the GND i was using a hole on the chassis on the back of the screen, is that suitable ?

                        If the boards are not mounted to the metal chassis then the circuit GND is not connected to the chassis, if you look at the circuit board mounting holes you should see exposed copper pads which will have trace going to the negative legs of the power supply output filter caps, you can then use those pads for your meter GND ref. point.

                          Not if the boards aren't connected to it. Then it isn't ground, it's just a piece of metal. You need to use the actual ground connection on the board.

                            What if i use speaker wire and use it to ground the PSU to the chassis of the tv ?

                              You could do that but why wouldn't you just use the ground on the board. You are just overcomplicating it.

                              You must use the secondary side ground, i.e. nothing on primary/live/danger side....

                                Lenovo Ideapad 5 15ARE05 startup issue
                                by db80
                                Hello friends,

                                I've been racking my brain over the past few months on the following issue:
                                I have a Lenovo Ideapad 5 15ARE05 laptop that basically works fine as long it starts up at all.

                                If you shut it down, often you hear the HDD still spinning and the Power LED remains on, it only shuts down if you force it (pressing the power button for like 15 seconds).
                                Then, if you want to Switch it on, nothing happens, only the Power LED lights on, nothing else. If you leave it, then after like 30-60mins it turns on itself.
                                I tried all the common alleged „fixes“...

                                Hello fellow tech heads.

                                Had this tv come in...issue stated reboots on wifi.

                                Indeed it does. However, with wifi off or using cat 5 cable no reboot issues.

                                So far ive changed mainboard and wifi module...also reset tv back to factory via service menu (4725)

                                Still same issue... i do have a psu to swap but cant see it being that really as works flawless if wifi is disabled

                                I thought fireware? But why only on wifi?

                                Is it an issue with the memory cache filling up and having to reboot for more ram??

                                At a total...

                                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...

                                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...

                                by rounin
                                Hi everyone,

                                I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck — hoping someone here can shed some light.

                                🛠 Original Issue
                                The machine initially wouldn't negotiate 20V over USB-C — stuck at 5V.
                                Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.

                                I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.
