I was switching the bulbs on the speedometer when the contacts for the T10s on the thin PCB tore off, and I accidentally shorted something. There was a burning smell with a bit of smoke and now, the entire speedometer lighting does not work - the rest of the bulbs (handbrakes, door ajar, tachometer) work fine.
Any ideas on what needs to be done? The meters seem to work fine, except for the speedometer bulb lights.

Is there a fuse in there which I have to replace?

A burned trace. It smelt of smoke and charring, so I'm assuming the smoke was from here.

The contact which caused the short. I was fidgeting at the back of the dashboard, feeling around for the bulb sockets when the short happened.

Now if I could find a conductive pen or a replacement PCB, this would be an easy fix but I can't determine whether it is the PCB or a component inside the meter that got smoked as well

looks like ur PCB circuit got fried there and the traces/leads got melted off. I think ur fuse is still good though.
If u are good at soldering you need to solder wires to the 2 trace leads that are lifted off the board to the bulb manually. But you need to be careful and check for short circuit before you install back into the dashboard n its best to test outside using 12v power supply first. Also u need check the traces that are burned to see they are still connected.
Its quite a lot of work so maybe u can ask a fren who is good in electrical / electronics to help or u can get a halfcut L2s meter and save urself the headache.
Also a word of advice for u - always disconnect your battery first before doing any electrical / installation work in your car. The thing is like 20+ amps and u should be thankful nothing happen to u. haha!
good luck in ur mods....
