    Re: Iiyama 2607WS suddenly dead

    The infinite reading for the MBR10150CT seems a little odd. Sounds like the middle pin is connected to nothing. Check it again. If you get the same result, remove it and check it out of circuit.

        I just ordered two 20100 and two 2045.
        Will solder out 2045 today and check it.
        The Caps are Taicon 25V 470uF. Seem to be ok.

        On center pin of 10150 I read +12V. Pin is connected to ZD770/1.

            After another resistance measurement of 2045, I think it is intact.
            I will solder the new 20100 in and check again.

                Ok guys, I soldered the caps back in, put silver grease on the new MBR20100CT, soldered it in, plugged the PS into the wall and measured perfect ~5V and ~12V on the connector to the controller board.
                The screen is working like a charm for hours now. I am so happy. Thank you very very much for your help and patience budm and jetadm123. Cost me a buck.

                Merry christmas to you and the Badcaps Forums!!!

                        Excellent work! Since you were able to get the replacement part so quickly, can you share your source, since so many people in europe seem to have trouble locating parts.

                            The parts are from ju-tec.de. A few kilometres away from me.

                                Thanks to this thread i fixed my Iiyama Prolite E2607WS.
                                Exactly the same part was broken.
                                Thanks to all

                                    Thanks a million to jetadm123, budm and others who helped solve formatthias problem. I had a 2607WS with exactly the same problem. I was on the verge of trashing it. I replaced the MBR20100CT and it is now WORKING!!!!!
                                    Brilliant!!!

                                        I think I have the same problem. I have removed the MBR20100CT from the board. On a digital multi meter I test 0.245 volts on each terminal and nothing when reversed. This sounds like it is ok to me but the only experience I have is this thread and some youtube videos about diodes? Could someone please advise if this is ok or not thanks.

                                            What is the exact problem do you have, blowing fuse?
                                            How about some good clear pictures of YOUR boards?

                                                Problem is the same as the op plus the guy above. Just stopped working completely, no power light nothing. I have two of these monitors so have tried different lease etc. As in both cases above it was fixed by swapping out the MBR20100CT but since I removed it I get the same readings between pins 1 and 2 and 2 and 3 so I guess in my case this is not the problem.

                                                    What DCV do you have between the two legs of the main filter cap (if you read the thread, there are step that we went through to find out what is going on).
                                                    All the fuses tested good with <1 Ohm?

                                                        On the main cap I got 315 volts. The 2 fuses show continuity and no resistance.

                                                            Hi all,

                                                            As the title suggests, how can I be sure that my EC chip is really dead?

                                                            I've recently gotten into this hobby of laptop repairs, and have successfully brought back to life a couple with some easy fixes, mostly shorted caps.

                                                            Now I'm working on HP Probook 455 G8, that had some "devil" run around on 3V line, burning a bunch of stuff. Luckily I have a dead 455G7 (for spare parts) so I managed to fix it (swapped burned parts) to a point that it will charge (both on barrel jack and usb-c), but it doesn't want to turn on. There is a 3V3 on a keyboard...

                                                            Hello. My personal laptop just died on me, and to my luck, it does not seem like it can be fixed, but wanted an opinion. It is a Star Wars edition hp 15 laptop, with a dax1bdmb6f0 motherboard (without dedicated graphics). I was watching a video, moved the laptop, it shut off and thinking it was just a semi unplugged charging cable I pressed it back in, pressed the power button, saw it light up and left to another room. When I got back it was off again, but this time it did not turn back on.

                                                            The 3.3v line has a really low resistance, and if I plug in the charger, I do get 3.3v on...

                                                            I have here a Magnum IA.100 which belongs to my parents.



                                                            The unit powers on & when the relay kicks in, you get a pop from the speakers (this might sound weird but is usual behavior for this amp). However, you get nothing coming through it from any of the inputs & no pops and crackls from any of the controls.


                                                            Because of the sound from the speaker when the amp turns on I have assumed that the output section probably works but I could be wrong & I'm not sure how to test that side of things further.


                                                            What Ive done........

                                                            i need help to repair a edm-033 ps2
                                                            history : as always hdmi port and usb ports destroyed after unplugged
                                                            after change them, ps5 dead too : 1 beep, no blue light. after inspection 1.8v power was shorted, and because of dead panasonic chip. after remove it : no short anymore
                                                            so i changed it
                                                            now i have got 5v stby,, 3.3v stby, 3.3v power, 1.8v power and no short on them
                                                            but the ps5 is dead again : 1 beep, near 10 seconds with power lines and then off, no blue light ...

                                                            i don't see any projection of liquid metal on pcb.
                                                            ...

                                                            I searched for the term "dead short" in the forum but no specific thread came up however if I'm just blind and couldn't see the thread talking about this please forward me to that direction.
                                                            So my problem is I don't know how to find the source of a dead shorted voltage rail. Dead short = ~0 ohm resistance.
                                                            I have two VGAs (HD 4850 and HD 4870), both dead shorted to ground on the memory rail. I have the boardview file for the 4870 and the memory rail consists around ~7892346 capacitors...
