    Good job. Like I said, most people would have not have solved the problem.

    So any recommendations for a broken track?

        C103: 10uF 50V - Readings: 9.32uF, ESR: 0.50
        C113: 33uF 50V - Readings: 36.66uF, ESR: 0.06
        I didn't bother looking up the datasheets for the above because I saw Rubycon and UCC KY caps. Both are excellent series caps and rarely go bad.

            Completely OFF TOPIC, but now that the OP's TV is fixed ...

            With summer winding down, I'm trying to take advantage of what is left of it so badcaps.net is low on the priority list.

            BTW, congrats to the UK for an excellent performance at the Olympics. It is good to see the home country do well.

                Glad to see you fixed it and it would have taken me quite some time to find that, if I had found it at all!

                    Thanks again folks!
                    Yes - well done- might depend where it is how big the gap it and whether you use leaded or unleaded solder - to be absolutely sure for long term, use a piece of wire.
                    Please upload pictures using attachment function when ask for help on the repair

                        Thanks again for help guys.

                        How I found it was to go into a dark room hold board over a bright light while examining it so you can nearly see through it.

                            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...

                            Need help identifying an IC chip on a Bush DAB radio (BD-1801)
                            by tyler123456
                            Hi,

                            Not sure whether anyone can help but I'm trying to identify the IC chip in the photo below.

                            I purchased a faulty Bush DAB radio (model # BD-1801) and identified that an IC chip was blown on it. Unfortunately, I couldn't read the manufacturer name / model number of the IC chip.

                            I purchased another (working) BD-1801 so that I could open it up to find out the IC details - but the IC chip details are missing (as you can see in the photo.)

                            Given the two huge blobs of solder either side of it I'm guessing it regulates power(?)

                            Anyone...

                            by modtool
                            Dear forum members,
                            I'm working on this power supply for ps4 slim, that behaves in a similar manner as other cases but I can't find a way to solve the problem.
                            When it came to me, externally the ps4 had standby voltage, clicking the disc eject button made the triple beep (without disc inside) and cliking on the power button made the blue power light turn on and then all turned off within 1 second.
                            When I opened it up, I found these components shorted:

                            Bush WI-1810 Internet Radio
                            by Johnny.p
                            I recently bought an internet radio Bush WI-1810, it came with a power supply that when plugged in promptly damaged the radio. I discovered too late that the radio was 6v and the supplied adaptor was 12v. The radio still powers on but the wifi is not working. I have attached a few pictures- Image 2 showing the board with damaged component top right labelled U8. There are several other similar components like U9 (image 3) that I'm wondering could be a replacement.
                            U9 has a code on it S5EJI- I have searched several smd code sites and the nearest I can find is for a mark of S5E -listing shows...

                            by Simplebeans
                            Hey guys i just got myself a Macbook Pro A1989 820-00850-a 2018, the seller said they had spilt liquid over it and since then it has never turned on.

                            I am using a Apple 61W USB-C Power Adapter and USB-C Charge Cable and on my USB tester i can see when i plug into the power i get around 5.21V and stays at 0.24amps. I am currently testing disconnected from the battery and only plugged into the USB-C Charge Cable.

                            When opening the machine I was greeted with corrosion on, in and around, in particular the U3100 (USB-C PORT CONTROLLER XA) and U3200 (USB-C PORT CONTROLLER XB)...
