Pickit2 Vpp Voltage Level Error

[noien]

I had been using pickit2 for around 5 months and this is the first time that it pop up this kind of error.

I use
USB ICSP PIC Programmer V2010
ICSP Programmer Socket



This is the error I got from pickit2.

This is the solution in the usermanual which I cant understand.

Is it my PIC faulty or the programmer is faulty.I try to use my PIC and the code that is in it is still working fine.
Pls help.
Thank you

Since you're using socket to program your 16F877 externally, You should tick the +5V square to supply +5V to your pic.

Something is shorting the circuit inside, hence the Vpp voltage level error. You may need to double check the connections.

I do tick for the 5v and since the pickit2 already been showing this since yesterday.so I forget to tick it since it is a screen shot

I did the troubleshoot using the pickit2 troubleshoot.
The first one is to test the Vdd and Vss pin(pin11 and 12).I use a pin header and put in the socket but the multimeter show 0 although it is suppose to be 5V.I had tested with the Vpp pin pull down and just let it be.It will show 0 in the multimeter.

The second step is to test Vpp when the the troubleshoot program will produce 12V but in the end it is still 0V



Is the steps done by me is correct?
Thank you

Did you check the fuse F1? Is it open? Look at P39 of the UIC00B Manual.

noien, good that you know how to troubleshoot
you are connecting the UIC00B to UIC-S, correct? The easiest way to test the VDD is the LED on UIC-S. It should be activated when VDD is ON. Else, there might be problem on either UIC00B or UIC-S (maybe some short). As for Vpp, you can measure pin 1 on the 40 pin ZIF socket to GND. It should be 12V or around that voltage.

If still cannot get the expected result, please contact support again, we will arrange for product warranty to troubleshoot and repair it.

The fuse is not open.But the voltage is just around 3V

I check the VDD on the UIC-S.The voltage is just 2V.
And for the Vpp,the voltage measure is 0V.
I think I will sent it back for warranty since it is just 5months old.But how will it take for the troubleshoot team to repair it?
Thank you

Agree with ober. If the fuse is good, any further trouble shooting would void the warranty. So just follow ober's advice and send both the programmer + socket to cytron for repair.

Why not get one more UIC00B for spare while this one is under repair?

LOL
How long will it take for the repair?
and a UIC00B is not cheap to me and because of this ,my pic16f is burnt
