Salmilo, don't forget to add that you asked about:
Given the very cheap cost, ,the complexity of the circuit and the need for real knowledge and instruments to check it, plus the absolute lack of a schematic, all point to plain replacement being the best option, by far.
Cool 🙂 Congratulations !!
But rather than trying to repair an obviously bad unit (it never worked), I'd download the TPA3110 datasheet, buy a Protoboard or whatever you need to experiment, plus parts asked for in the datasheet example, and build one as an experiment.
You will know what you have, any errors will be yours to learn (instead of, say, a poor PCB design, faulty/cheap parts or whatever "they" did.
You will learn much more 😀
C'mon, I can't believe nobody asked about TPA3110 somewhere 😱
EDIT: OK, I have to agree with you on this.
I googled >>tpa3110 trouble<< and the first 3 pages yield just one guy with a problem 😱
Which for me means these chips are quite good !!! 😛
So i again suggest: get the parts and build one .
Best case, you will gain experience and repair the faulty one yourself 😛
Cool for the advise for building one and I agree about the quality (from my research) and could I scaveng the ic from my inopperable board
There is a guy that made this "ravebox"
http://m.instructables.com/id/DIY-Tough-Bluetooth-Speaker/
And I want to make a radio for my scooter (vespa style) bluetooth so the radio can give me turn by turn directions from my phone and use Pandora at the same time and the one speaker works for what I want but I have a 6' headphone chord hidden the body panels right now and no fm radio ither

And I would like a lil more volume so I dont have to have the volume maxed out to hear while I ride and is there a simple fix for the 3 watt output from the bluetooth module used in the ravebox (it took a while but I found a spec sheet that told me so) like some resisters or a lil magic pixy in a bottle wired in lol
Threads merged. Only 1 thread per topic, please.Thank you but how did u do that u must be the teki god showing off flexing some virtual muscle lol jkjk
I had a same problem with hifimedly t-1 amp, suggestion was a prob bad chip and no one really was able to give a way of "trouble shoot", just threw it away unfortunately..., one channel was fine.
I have tried to trace the circut out manually and it seems that from the ic the curent is lower from the output side bad ic chip I guess
So after much research I was rong about the output of the bluetooth fm modgule that I chose to use it has the same output as a headphone jack the only one that a spec sheet was different it included a 2 channel 3watt amplifier and the price difference was 5 dollars
Very glad that the Bluetooth MP3 Decoding Board Module w/ SD Card Slot / USB 2.0 Port / FM / Remote* from dx.com ($11) can be wired directly to the input of the amplifier
