JDSU PSU 2114-30SLT problem

[por501]

Hello, I hope someone can help me.
I have damage at resistor R16 on Top board of power supply 2114-30SLT.
The R16 was burn So I don't know value of R16
If someone have JDSU power supply same model.
Could you please help me, open the cover and check value of R16

How many ohm of R16? Thanks.

If by top board you mean the power section, then I believe it would be a 330 kOhm.

Double check this schematic to make sure your PSU is the same as this:

I'll check my power supply when I get home. I'm not sure what model I have.

How did you manage that? Odds are you have bigger problems than a single blown resistor.

This. I had a PSU that shorted out and made one helluva bang yet when i took apart didn't see one burnt component.

Thanks everybody and sorry for late reply.
I change the resistor to 500 ohm and 50 ohm respectively.
Both resistor it work but not 100%.

First, I need to tell that my English is not good.
I try to explain more detail after I put R16 500Ohm and 50Ohm.

1. I test only laser and power supply without the Machine.
when I turn ON input power supply, Ar Laser have laser beam it look normal.
2. But I must install laser and supply within the machine, It have signal control from machine.
3. After that I turn ON machine, it have sound like spark inside power supply.
This event occur same R16 burn in the past.
It look like machine try to control laser power beam but it fail.

1 more thing about R16, It burn but I can see first and second color.
It is green and brown. but cannot see third color.
So this is cause why I try to put 500 and 50 ohm.

Now it still not good with the machine.
Could you please more suggest.
