Smd parts on the main board p30 pro
Hello. I am wondering if you know what size a smd resistor is on the board please. I have full schematic. It is part reference r1278 100 ohms resistor. I believe it to be one of the smallest parts available but I don't have such a measure device on my microscope. It is a resistor right near the screen connection. Photos are attached. You can see missing resistor.
I'm unsure why it appears to have a fry mark where it obviously burnt out, i will fit a 100 ohms resistor and then test that pin to earth.
Also can you help advise how to remove the shields on this board, particularly the one on the rear side of where the battery connection is. Is it just a pry off or is there any solder to melt?
Any help or advice would be much appreciated
