      One is probably something very low ohm like 0.1 Ohm because it is voltage supply and also acts as a fuse and the other is 49.something Ohm.

          Try to see as hard as you can get, if the first letter have "latch" like "1"... then very very carefuly and slightly gently whipe up once and see if it revial any more information. Be sure that burned paint is very fragile so on any attempt to clean it may go off. I will use first light brush with ipa, and future with more and more force. It may be 1R00 or R100 on it. The second resistor is 49R9 marking.

                      Plugged into the OBD connector wrong?

                                  Acer Nitro 5 AN515-54 - burnt PU301, no power, please help
                                  by Tony182
                                  Hi, I received a non-working Acer Nitro 5 laptop (AN515-54-5133) for repair. When I plugged it into the power adapter, not a single LED lit up, no light or sound codes at all. So I unplugged it from the power source and turned it over to open it up and as soon as I did, I was hit by the smell of a burnt component.

                                  I was hoping it would just be a capacitor, but after opening the laptop I found our suspect labeled PU301. On one side, 4 pins are bridged together on a shared copper trace, and that's exactly where the component was burnt. After desoldering it, a fused remnant of the component...

                                  HELP IDENTIFY BURNT COMPONENT - HONOR MAGICBOOK X14 - BOARD DA0H99TB8E0
                                  by Alfonso5
                                  Hi everyone,
                                  Iā€™m working on a Honor MagicBook X 14 (Model: NBR-WAH9) that doesn't power on. I found a catastrophically burnt 8-pin IC near the touchpad connector (CN14 TP).
                                  Motherboard Model:DA0H99TB8E0 (REV: E)
                                  Problem: The component is so badly burnt that the markings are illegible. It is located right next to the ITE chip and the TP connector.
                                  Request: Could someone please share the Schematic or Boardview for this board? Or if anyone has this board on their bench, could you please identify the markings (silk screen or chip ID) for this 8-pin IC?
                                  I have attached...

                                  What are these components that detect paper in a fax scanner

                                  PROBLEM SOLVED
                                  I DIDN'T REALISE MY SMALLEST SOLDERING TIP COULD JUST FIT BETWEEN THESE COMPONENTS.
                                  I MANAGED TO REMOVE THEM WITH NO DAMAGE TO THE BOARD AND I HAVE MY INTENDED END RESULT.

                                  On a Possio PM70 portable fax machine which has a scanner that detects when you push a piece of paper into the scanner slot.
                                  It is these two small (3mm long) components that detect the paper and start the scanner feed motor which pulls the paper into the scanner.
                                  (These are on the circuit board for the keypad and not the main board)

                                  Hi all,
                                  I came across this very active forum with knowledgeable folks on electronic circuits and components, while google searching for the details of my burnt IC marked 7603 in Intel NUC board. I joined this forum today and this is my first post here.
                                  I recently got an Intel NUC 10i5 and had installed Linux Mint and was using it for about a month when it died suddenly and did not power up after that.(Power Adaptor is ok). When I opened the NUC , there was a burnt IC marked 7603 (and ILCB in second line). I am unable to find the details/datasheet of this IC. I will be grateful if...

                                  Precision 5550 LA-J191P No Power, Burnt ISL9538
                                  by swimllamaswim
                                  I picked up this Precision 5550 to fix up recently, and found that the ISL9538 chip was burnt on pin 14 (CSIN). The two left side Type C ports negotiate at 20v, and the right side one only negotiates at 5v. I also found the EMI protection diode, DT35, was burnt on that side. I pulled the ISL9538 off, checked for any other obvious shorts, repaired the pad, and put a new one on. Now, I still do not get power, and there is a rapid clicking sound from somewhere on the board that I can't pinpoint.

                                  Here are the voltages measured at that chip:

                                  To note, DCIN at Pin 17 is low,...
