    Help identifying components

    Hey guys I'm having a bit of an issue identifying some components on a circuit board and was hoping someone could possibly help me out. The board is from my dash panel in my car and it's died or rather voltage protection has kicked in as it's seeing 24v instead of 12v I've narrowed it down to some resistors mounts on the board through trail and error but can't find the values anywhere to order some replacements the first pic is a group of 5 in the centre and the second pic is a resistor on its own. I say resistor but I'm not 100% sure.

    I realise I'm asking a lot but I really need help and cant think of anything else to try.

    Many thanks in advance

    Neil

      wondering if they could be colour coded fuses ..

          I’m not sure my friend I thought they were melf resistors. When I applied abit of heat trying the see if there were any dry joints the voltage reading changed. Also I measure resistance with my fluke and got a reading but am unsure if the value given is correct

                      Sweet do you know how I can read the values I'm sorry but I can't seem to see the beginning or end as they look pretty evenly banded.

                          Re: Help identifying components

                          it will be the standard resistor color code, the dots are near band 4 or band 6 and are TC (Temperature Coefficient Marking)

                              Thanks buddy I’ll look at the ones without the dotted bands and try and make an educated guess

                                  What do you mean by "voltage protection has kicked in as it’s seeing 24v instead of 12v" I doubt the resistors are bad

                                          No LCD image after connector replacement – lifted components and damaged resistor (Nintendo Switch Lite HDH-CPU-02)

                                          Hi everyone,

                                          Sorry for the person who’s going to read all this !
                                          I'm on a Nintendo Switch Lite, motherboard HDH-CPU-02.

                                          While replacing the left joystick, I had to remove the motherboard to access the connector underneath. When I lifted the LCD connector latch, it broke (the plastic had become brittle over time), so I replaced the entire connector.

                                          During the desoldering of the LCD connector using hot air, three small components located just below the connector (likely 0402 capacitors) came off and remained stuck to the bottom of the...

                                          Assistance with identifying resistor value on 820-02918 A2992 board?
                                          by ugamazing
                                          Working on a 2023 M3 A2992 unit with 820-02918 board, and it uses a new USB-C power architecture, with rectangular controllers. I do not have a perfect-matching board, so have been repairing this one the old-fashioned way (slowly).

                                          I managed to blow-away a single resistor that I can't find and can't determine the value of. It connects to ground, so I went ahead and stuffed it with a 100K resistor in case it's a simple pull-up. But, I'm now having issues with that side of the board, and am curious if it's possibly related to this resistor! I have no schematics and no board view, so...

                                          Hello Guys,

                                          Can you please help me identify these components from the motherboard. I saw a similar topic, but it was for HP840 G4 (https://www.badcaps.net/forum/troubl...arging-problem) Are those described there the same components?

                                          In the first picture, I have circled in red the burned components. It was due to short switching positive with negative. Probably the motherboard will not work, but I can try to repair it. It is a laptop for experiments,...

                                          Need help identifying resistor on Asus FA507RC DA0NJNMBAD0 schematic

                                          Hi colleagues,

                                          Looking for a schematic DA0NJNMBAD0 or the MP2845A 6-phase PWM controller.

                                          Working here on a DA0NJNMBAD0 rev D motherboard (Asus FA507RC) with liquid damage. Board has some tiny corrosion around the MP2845A controller and one resistor is missing. I need to know the value of the resistor, but no schematics are available. Not even for the MP chip or anything similar (this is a 6 phase PWM controller).

                                          On one side of the pad 20V is present. The other side connects to a cap and to pin 16 of the MP2845A. Resistor seems too small for VCC...

                                          This resistor is on a small board the fan connects to in a Brother MFC L5900DW. The fan does not work, and when testing this resistor it shows no reading all the way from 4M ohms, down the a continuity test, so appears to have failed open.

                                          I've tried using a coupld of resistor calculators online, but I'm not sure which end is which on the resistor, and going both directions on the calculators I run into a value that doesn't have the correct color as an option.



                                          I, believe the colors are black gold violet black orange, but maybe I'm mistaken on one of th...
