ya i know from schematics R7050 + R7051 + R7052 should be 2.21ohm..
let me get a new multimeter, as now it is measuring 10.x ohm..
There is a glue blob around R7052 but I saw brownish shadow within it near R7052 pin2 .. when I cut open the glue blob I confirmed that pin 2 of R7052 was probably heated up somehow that causes burn mark on the surrounding glue.. now R7052 measured around 7.9 ohm between pin 1 and pin 2. R7051 measured around 3.0 ohm (however between the 2 pole or any 2 screws the multimeter read 0.9ohm, assuming this is internal resistance between the 2 pole). I guess subtracting that from 3.0 will give 2.1 ohm which means R7051 is probably OK.
I measured R7050 and it is also 0.9 ohm. again subtracting the internal resistance should be 0 ohm, which also means R7050 is ok.
