    Suspected DWM156 D-LINK USB Adapter Mainboard With Leaky Transistor

    Hello Badcaps.net,

    Does anyone has any clues what the value of this SMD transistor(PIC01). I suspected it's a leaky transistor where the mainboard of this DWM-156 DLINK USB Adapter failed to read the SIM card whenever I tried to use it to access the internet service. BTW I have attached some of the photos of the adapter mainboard and other parts(PIC02,PIC03,PIC04) so if you guys have any ideas for fixing it you're always welcomed to post them here. THANKS AHEAD OF TIME..

          The marking code suggests a BFQ31AR . No schematic available https://apps.fcc.gov/oetcf/eas/repor..._id=KA2WM156A3

                  Dell Latitude 7420 - Touchscreen not working since Mainboard replacement
                  by Mirenia
                  Hi everyone,

                  I've got a little "problem child": my Dell Latitude 7420 2-in-1, which had a faulty mainboard.
                  I replaced it, but ever since, the touchscreen no longer works — and honestly, I’m running out of ideas…

                  In Windows Device Manager, I just see an I2C HID Device with error code 10. Sporadically, the touchscreen is recognized correctly for just a few seconds, but I haven’t been able to determine under which circumstances this happens.

                  The touchscreen also doesn’t work in UEFI/BIOS, although it’s enabled...

                  MASTER TL240 and new mainboard LW36BKC01
                  by orcic
                  Hello,
                  I have an old MASTER TL-240 LED TV. Since it stopped working and it had a DVB-T receiver that is being dismissed in Italy, I've decided to replace the mainboard with a DVB-T2 one.
                  The original problem was that when switching on the TV, the power LED was transitioning from red to steady blue, without showing video or audio.
                  After checking some voltages on the power supply board (HKL-240101-B Rev. 1.4, HKL from now on) someone suggested me to replace the mainboard.
                  Now I have some doubts about how to connect the new mainboard to the old power supply.
                  First of...

                  Vizio M43-C1 - How closely do I need to match the mainboard number?
                  by Devonavar
                  I have a Vizio M43-C1 stuck in a reboot loop with no backlight.

                  I've tested all the voltage rails coming out of the power supply and they are "normal" for this model (PS_ON & DIM go high when turned on, BL_ON & 3D_ON are close to zero due to backlight power flowing through the mainboard, 5VSB is 5V, and 12V is 19V, which is apparently normal for this board).

                  Basically, I get similar results to Garry in this post: https://www.badcaps.net/forum/showthread.php?t=80346

                  So, I've ruled out the PSU for now.

                  The reboot loop...

                  QN65QN90A - Mainboard MLCC failed - now bootloop
                  by l0lhaxz1
                  Hi

                  I have a QN65QN90A which was purchased around launch I guess making it about 1.5-2 years old... had been working fine until a few days ago, simply went black and would no longer turn on (at all). No standby light and no typical PSU relay click etc. Absolutely dead.

                  Pulled it apart without doing much research first, suspecting the power supply as it had a faint buzz (I guess due to the forthcoming found short), investigated PSU for some time and concluded there was no fault that I could spot with the board removed.

                  Came to learn after a bit more research...

                  by Jembang
                  good day hoping someone can lend a hand, im repairing smart tv 50 inch, status when turning on back light is dim but you can see the tv logo then slowly fading out to black, i check the supply to tcon, i only read 5+v, must be 12v, i removed lvds cable and check voltage to mainboard turned on its also 5v, then i remove the cable mainboard to power supply, i read 12v in power supply, thinking that the problem is in the mainboard, coz theres 12v in power supply, i also check while turning on checking volts in main board 12v dropping to 5v, im just new repairing in TV, hope someone see my post t...
