A new original proton speedometer odometer costs rm150. For me, i decided to change it instead of attempting repair
Finally had some time to try to fix my Iswara speedometer. My odometer and tripmeter is stuck but the speedmeter is still working. Workshop quote me RM180 to replace it but I tried my luck in repairing it myself. Will tell what was the result but before that, this is what I did step by step:

The odometer stuck at 20k+ KM since I bought the car 2nd hand.

Took out all the 4 cables that were connected to the switch which are air cond switch, rear wiper switch, rear windscreen heat plate switch and hazard light switch. It was a bit difficult because of cramped space.

The plastic cover has been removed. Next up is the meter panel.

That's the speedometer cable. Not sure whether its in good condition. But when I drive the car, it spins.

This is what it looks like behind the speedometer.

I took out the odometer and trip meter separately. It looks very complicated and fragile so be careful and think twice before you decide to dismantle it. I made the decision to repair myself because I was planning to change the speedometer but decided to try my luck. When you take out the speedmeter needle, please be very careful, the coil that is connected to it looks very fragile.

I examined the gears, noting was broken and there wasn't any wear and tear.

Then I found out that a gear that is connected to the speedometer cable was stuck with some dirt. So I cleaned it and applied some WD 40.

The green gear will move the odometer and also the trip meter. Until now I can't find the problem because all the gears move smoothly when I turn it. I applied some WD 40 to all the gears throughout the process.

Then I found the culprit! It's the white gear which is connected in between the odometer and the trip meter. It seems that for some reason, the white gear could not move the trip meter gear thus it gets stuck and makes the whole thing stuck. So I decide to take out the white gear. It will make the trip meter useless but odometer is more important than trip meter. Better to have 1 working rather than nothing. But the problem is the white gear is difficult to be removed. So I decided to take out the main gear for the trip meter.

There will be a black gear in the place where I have marked a blue circle. I unscrewed the pin and took it out. So now the trip meter won't be moving. The white gear can now move the odometer.
And the result, the odometer works!!
But... the trip meter is not functioning (who needs it when the odometer is working) and I realised that the speedmeter needle is not as steady as before. Its shaking when the speed is below 40 KM/H. I did found out the the reading is slightly lower than before. I did took the meter out and reassemble the needle. Its still shaking but I guess the reading is ok now.
So what's your comment guys? Wana try it out? Or just change a new one? I spend almost 4 hours and it didn't cost me anything
