HX Stomp won't start (just bought it)

[Snys]

Bought a used HX Stomp the other week. Previous owner says he has changed the USB-connector (not saying why though) on the PCB, and after that the Stomp won't start. And yes, the Stomp doesn't start, and also it looks like the connector has been swapped out.

When trying to start, the screen makes a very quick flash, then nothing happens. No matter how long I wait it won't boot.

I've tried to press and hold in different combinations to reset, update and son on, nothing happens.

I can not connect to HX Edit or Line 6 Updater.

It's tempting to get a new USB-connector and make a swap, but. When I check the connections from the connector to the PCB, it seems ok. I have a second Stomp that I can compare with and as far as my understanding I can not find anything wrong.

(My second Stomp has no problem with connection to Edit or Updater).

I've read so many posts about Updater and my guess is that it's a problem with firmware, but I don't know. It's hard to know when I can't connect to Updater.

 

Sorry for a long post.

Anyone have an idea of what might cause this problem?

 

Best regards

Yes. You bought a device you were warned is not working. And it's not working.

 

From what you've said the problem is almost certainly a hardware problem. It needs to be repaired at an authorized Line 6 service center.

Yes - you bought a unit that doesn’t work!

 

My guess - hardware issue, needs a technician to repair it.

 

Hope this helps/makes sense.

I suspect the previous owner probably fried the board when attempting to change a broken USB connector. 

 

If the USB connector potentially caused the problem, simply remove it completely and make sure none of the leads are shorting with each other. I doubt the HX Stomp needs the USB connector to start... and that would eliminate that as a potential problem. If it still momentarily flashes... the USB had nothing to do with it.

 

I hope you bought it for dirt cheap... knowing it didn't work.

Thank you so much for the support! Yes I bought it knowing it was broken (for like 40$), but I’m a curious man and I was tempted to give it a try. 
 

I dont know how hard it is to fry a board but it looks clean and connection is good around the USB. 

I’ll try to remove it and give it a go.

Hope you get it working. The good news is - you can’t make it any worse!

Buy a 60W solderer and a solder sucker and remove the USB socket and all the soldering material from the back of the socket, on the PCB - and see if it does boot. Good luck.

Have you eliminated the power supply as the potential problem for the dead unit?

You say you have a "working Stomp" so you obviously have a 2nd power supply to try.

Failing that, ^^^ this ^^^

I’m looking for a good solderer, hoping I can borrow from a friend. 
I’ve tried my other power suppleant and it makes no difference. 
 

Thanks for helping me out!
