BM54 dead channels repair?
I've had no luck searching here or on Google. Has anyone located and repaired the common fault that makes the speakers stop working on the BM54s? I have a dead one I'd like to revive.

search on ebay.de, you will find a lot of audio repair kit's(great for diy), or just send your BM for repair; i did used an tda 7560 audio kit presoldered (brought from here:PSC-Audio | Module KIT | Module PsC-Audio | KIT127D - 4x34W (TDA7560), was about 19 euro shipping included) and, after about 3 labor hours BM was alive again, is not very complicated to do but you will need some electronic skills..

Thanks dude, that's a great link. Shouldn't be a problem at all for me.

you are welcome m8, don't forget to supply at least 3.7V to MUTE and STANBY inputs :)
hint#1 cut ALL power supply lines to old amplifiers (from BM54) hint#2 if you have bluetooth installed, you will need to feed the new amplifiers directly from old amplifiers inputs (after BM54 audio integrated switch) or you will loose BT audio function (i can send you pics about this subject) hint#3 you cand find on BM54 board 2 lines originally used for mute and standby: better use these, will avoid annoying power up/down sounds...(i can send you pics about this subject) regards |
Yes please send the pics, will PM you an email address mate, and thanks!
|
Can you please send me pictures and the electrical scheme?
Thanks! |
