can you help me to fix this problem, thank you!My 2D42 I found R15 is burned out.
After Replace Resistor-Fixed,1K,1/16W,0.1%,TCR25ppm,R0603.
But use DMM to measure resistor 750 K ohms , It display wrong reading 438K
and can’t measure over 100mF capacitor (no reading) .

Dear Sir,
Please test whether the resistance of R14 is normal according to the figure below.

Today measure all resistor are correct.
But use DMM to measure resistor 750 K ohms , It display wrong reading 438K
and can’t measure over 100mF capacitor (no reading) .
can you help me ?
