Uc3825 based smps issue

[aksnis1]

Hello 

I am trying to repair a smps power supply based on UC3825A 

Problem is the resistor R49 & R34 get burst as soon as i start the smps

I am not able to find out the issue

SYS_ECON is a 0-5v given from MCU desired by user to control 0-180v smps output

I would disconnect one end of R35  and see if that fixes the problem or just replace it. It maybe breaking down under the higher voltage?
