content: Hi people, i`m new here and i`m from Brazil, i just got into a research on google trying to find were and wich model of bga chips Behringer uses on UMC404HD model, it`s very hard to find anything here in Brazil and to fix it here is VERY, i mean VERY expensive on their store, it`s about the same price as a new audio interface. The guy from the store told me that the problem is the BGA Chip.. what happen to it before i got it from a friend was, he used a wrong power suply (12v) and it stoped to recognize as a usb device. So i`m trying to find the correct chip to buy it from a cheaper price on internet and then take it to the technician, can you guys help me in any way about that? I`m sorry for my poor english but i have not used it for a long time now.. Thanks in advance!

content: I hear a few alarm bells in my head here.Have you agreed with the technician that you will bring them a BGA chip and they will fit it?What if this doesn't work? The chip you buy could be fake or the wrong one, or the chip might not even be the problem.Who pays for what, then?In the UK you can buy this interface brand new for less than £100 with a 3 year warranty if you register it.A working used one would surely be in the £50 ballpark, about what you might expext to pay for even the simplest of repairs, say power supply regulator, let alone a GBA replacement.If you brought me a BGA chip from who knows where, I would not fit it.Nor would I take your money for fitting this chip, knowing it was entirely your risk and I just keep the money anyway when it doesn't work.

content: Quote from: Audiorepair on October 20, 2020, 06:38:51 pmHi mate, thanks for your reply.The thing is, i live in Brazil and here, these interfaces, USED are about R$1400 (Braziian Real), so, i got this one as part of a payment from a friend who own me some $$, about who is going to may loose money in the process? ME! The thing is, there is no motherboard to change the whole thing on my country, to import it from US is gonna costs R$1310 + Techinician job (about R$300), so, a new board like this one here costs about R$1600.. So, you can cleary see that i`m giving it a try, because i already lost R$400 getting it like that to fix.About the guy from Behringer store, he never told me that he would do the bga replacement, actually he said he wont but he gaved me the reference chip number because i asked him to.I`m going to give it to another technician who is a friend of a friend to see if the bga is really the real problem but i will do this with no much faith because look like it is.So, i got some answers from 2 guys and now it is all i have, 2 XMOS chips references.1 - XS1-SU01A-FB96-C5 (Given by the Behringer`s technician).2 - XS1-U8A-64-FB96-C5 (Given by a guy who i saw here in a post and he is trying to fix his onw umc404hd and still had no lucky doing it).Does any of you guys know if they can perform the same about funcions, voltage, etc...?I will appreciatte any piece of information.Again, thanks in advance!

content: Both those chips have areas of bootcode that require programming.It MIGHT be that your interface doesn't actually need to use any such bootcode, and the chip will just boot into a generic state without any, so a blank chip might just work in your interface.I kind of suspect it won't, though.

content: This is not really my field of expertise.I believe you can get BGA adaptors for a variety of EPROM programmers and the like.You would need to pull this one off the board and try to read the bootcode, or at least be able to tell if it has any or not.If it does have boot code and will allow you to read it, (i.e. not protected), you will need to copy it onto the new BGA chip.I would guess that any equipment capable of reading and copying the code would also be able to write it to a new BGA.You really need an answer from someone who knows a lot more than I do about it, or who possibly could tell you if there is no bootcode to worry about, which would be the best outcome.

I will look for somebody who could help me with that or find the equipment to do those actions that you told me.Once more, many thanks for you replies!I hope i can do something to fix this thing, i`m really not happy with the idea of loosing the R$400 i invested.Cheers man.
