STM CircleOS forum / Target Power Failure: Measured X

Hi everyone.

A friend gave me this STM32 Primer 2 but i have had problems with it since i got it. Then i was driving home with it I noticed that it was getting a little warm, while it was turned off. Then i came home and installed the drivers that came with it on my computer then i started charge it with the USB and it just gave this red LED in the top as it should then chargeing. Then i left it for 6 hours or something and then i came back the red led was still on, so i tried to turn it on but it wont turn on (Then my friend gave it to me he started it up and it worked)

I found the warm spot and i kinda burned my finger!

Watch this picture below

I think the heat comes from the yellow component.

Also if i try to flash it with RFlasher7 it says:

Target Power Failure: Measured 1.5000000v
Target Power Failure: Measured 0.8000000v
Target Power Failure: Measured 0.9000000v

And just keep doing that with random numbers.

Help is much appreciated

Regards Trio36 & I am sorry about my english, stick with me

I found out that my volt regulator is broken. Is it possible to replace the component? Or maybe return the product?

Search some electronics forums if there is group orders from digi-key.

it's this component 497-4222-1-ND
http://search.digikey.com/scripts/DkSea … -4222-1-ND

Order 2-3 pcs. They are about 3-4e / pcs

Edit:
You can also try if you can have samples from ST.
