hi anybody have dead fvdi ? no led flashing and computer dont see this chinese black box. Everything go dead after 6 plug ins to usb port before everything was ok. Any solutions ? chinese man dosnt respond

If your fvdi is not detected by computer ,you should have a look fvdi usb connector ,interfaces chinese usb B connector bad quality ,verifiy if you can see 4 pins ,one of them could stay blocked ,I had this problem with even original AVDI

Hi,

Pls open your interface without plugged any usb !!! It is important !!!

Check the X1 Xtal component with multimeter two pins. If the multimeter beeeeeep then you LPC processor is damaged !!!
After pls check C39 capacitor and if the multimeter again beeeeep then 100% your interface LPC proc is DAMAGED.

You will be return your china seller to repaire. Or pls write me pm.

Hi all,

Now I still working my project, but I have some solution !!!

Abouth, somebody know what are the two components for ORIG AVDI?
If so, pls let me know.

Thank you, G

Looks like tantalum capacitor.

NOT, maybe Dioda as I know, but which?

**kelekele** · 13th March, 2015, 10:27 PM

This 2 components is simply(not zener or other types) diodes,used for filtering voltage or switched supply.

**andrym3** · 14th March, 2015, 06:42 AM

diode left

rotection reversing polarity
diode right :switched supply

**andrym3** · 14th March, 2015, 07:09 AM

You can use any diode rectifier

**gopelhu** · 14th March, 2015, 08:02 AM

Can I use normal dioda or bipolar dioda?

**andrym3** · 14th March, 2015, 08:56 AM

diode normal rectifier like serie 1N4001,2.....7.

Hi all,

Pls check the attachment, I found this Dioda an other orig AVDI.

What is this marking code? I checked with systek.ru but without success.

This website is a best these marking code
