Hello,
I got my hands on a 2e hand 360 s6 vacuuming robot i wish to repair.
Unfortunately, a common (and mine) problem is that the radar, used for navigation is not working.
a second unfortunate thing is these problems seem to have many different causes, from dirty lens, to stuck hairs so it can't move, to broken down radar module to a faulty PWM (mosfet?).
the issue I am dealing with is what I believe to be a faulty PWM.
I have come to this conclusion as this seems to be an issue that others have dealt with also, but I have not found anyone...
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

by RofixHi everyone, I wanted to kindly ask you for help, I have a problem with my Dell vegas/turis mlk kbl-r 17841-1 wx2rr PC, it turned off and I was no longer able to turn it back on, I'm checking the various voltages, unfortunately I found the 19 v up to the input components PU4411, PQ4401, thank you all for any advice

by abajorI have the above mentioned MBP, quick scan with thermal camera revealed that only U3200 was heating up. I found that C3208, C3219 and C3205 were all reading ~6.8ohms to ground.
so I swapped U3200.
I connected the PSU again for a quick check on thermal it's drawing about the same amount of current but now I'm seeing only heat radiating from U7800 and the T2 chip from under the black shielding fabric, and the bottom of the board.
It's hard to judge the actual temperature without removing the shielding.
Does anybody have any insights?

I downloaded a BIOS file from Lenovo and once I extracted the actual BIOS from the executable, it is 16MB in size, but my IC(Winbond 25Q80DV) is only 8MB in capacity. I have read you can trim the BIOS file with a hex editor but I can't find any instructions on specifically what you will remove.

by michdundeeHi all,
I'm facing a issue... hope you could help me. I have a T-CON board BN41-02112A from Samsung 55inch Curve TV.
I have just only 2 status blue LEDs ON since LED3 is off. I have tried to test some test points but VON is NOT OK very close to 0V. Is there someone that can help me on the debugging the issue? I'm supplying the board from an external 12V voltage source.
Thank you in advance.
BR,
Michele

by GeryMixHello everyone!
I have a surface pro 4 (1724) with corporate management set up (in this case, I understand it's called SEMM). In the operating system installer (Pro version), after connecting to Wi-Fi, it asks me to enter the company system. If I don't sign in, it won't let me continue (similar to enterprise enrollment on chromebooks). This can be avoided if I install the Home version instead of Pro, and then upgrade to the pro version, but this is not very elegant. I would like the machine to be as it should be in factory condition. That's why I would like someone to remove this restriction...-

by pc boyHi everyone. An HP X2 1012 G2 came the other day. The problem was that the device drained the battery while off. I checked and saw the current is 0.2 before start. I went and checked parts on the MB and saw that the JHL6340 IC that is responsible for controlling Type-C gets hot. Everything worked fine and I checked charging and data of type-C both were OK. I went ahead and replaced the JHL6340. Now it does not get hot, no current before start, charging is OK, but the data of type-c is lost. I mean any type-c device like flash memory or hdmi adapter etc. do not work. I tried another jhl6340 and...Today, 03:34 AM
