My instrument cluster stopped working and when I plug it in, I smell some burning. I found this component smoking and seems to be the source of the trouble. Can anyone please help me identify what it is?

2\$\begingroup\$ the smoking component is probably overheating because of the problem at another location ... why is the component of interest taking up less than 1% of the picture? \$\endgroup\$ – jsotola Jun 7 '20 at 3:38

1\$\begingroup\$ Maybe a capacitor? Hard to tell from so far out. Try desoldering it and see if the board starts working again. \$\endgroup\$ – user1850479 Jun 7 '20 at 3:39

\$\begingroup\$ It seem to me a burnt LED. Is there some optical conduct (acrylic part) above it? But, as I said above, you should not risk to ruin your panel putting inexperienced hands in it. \$\endgroup\$ – mguima Jun 7 '20 at 13:15

Hard to tell from this scale - It seems to be white so it could be another SMT LED? I would try desoldering the component and see if the rest starts working then.

\$\begingroup\$ The component is silver in color and not an LED. I have also tried desoldering it but nothing work after that. \$\endgroup\$ – lasbreyn Jun 8 '20 at 7:47

It would be easier to tell if you took a picture a little closeup. But from what I can see it looks like a surface mount led got cooked. It could be a capacitor as well. Try removing that component and see if it works. Check the inputs to this board before plugging it in just in case. Edit 1: after looking at the closeup picture
https://www.budgetronics.eu/en/capacitors/smd-0805-ceramic-capacitors/smd-ceramic-capacitors-0805-1-2pf/a-13732-10000114 Looks like one of these capacitors, not sure about the value.

\$\begingroup\$ Thank you @theCNN, I have added a more close up picture of the component. \$\endgroup\$ – lasbreyn Jun 8 '20 at 7:45

\$\begingroup\$ It's not an led probably a capacitor I'm out off by the white colour, it is shally a beige colour. Could be one of these budgetronics.eu/en/capacitors/smd-0805-ceramic-capacitors/… not sure about its value \$\endgroup\$ – theCNN Jun 8 '20 at 9:44

\$\begingroup\$ It could be an essential part of some ic or some other circuit that requires a capacitor to operate. \$\endgroup\$ – theCNN Jun 8 '20 at 9:48

\$\begingroup\$ Yes it is not an led, I tried that and didn't get any change. \$\endgroup\$ – lasbreyn Jun 10 '20 at 0:47
