0.2 ohm Resistor

p.s. I was gifted this board in this condition, so just trying as a pet project to revive it.

Those R numbers on the silk screen don't mean much in terms of value, they usually indicate the number on a schematic, where did younger the value of 0.2 ohms? If it is, it's usually a type of fuse, where they would use a quick burn type resiste

LOL!
 
Well I might very well be mistaken. But I googled the R200 transistor and it seems to be 0.2ohm.
There is another spot on the board that has the resistor in there, and it's a R200. Photos from google also confirm all needs to be R200 for some MG5050 boards.

Then I saw RS Online sells 0.2ohm resistors ( on board ), but they have R20 printed on them. Other google images all have R20's on the MG5050 boards.

All very confusing ...

R20 and R200 both seems 0.2 ohm
 
I see from photos on Google, the missing resisters are R20 , 0.2 ohm, which is around that of a piece of wire, I would say they "fuses"

Yeah try and have two 01x labeled resistors. one is 10 Ohm and the other is 100 Ohm. Now that was an orgy, Nothing worked and no one could find the problem. also cant measure mini smd res with multimeters. too bloody small.
 
It is 0.2 Ohm 1% current sensing resistor. Are you sure it is blown?

It's not that it's blown, it's that it totally missing from the board. Look at posted pictures please.
Someone took them out.

Are you sure that they have been removed (pic isn't clear enough to see)? Quite often a PC board is designed for multiple models of the device and where a function isn't available unused components are not mounted when it is manufactured.
