Hello colleagues, I have a Home Theater Onida Japan 5.1 audio system that, for an audio output, comes out around 15 v. The kitchen burns when I put it on 2.1 it is not heard, it is only heard on 5.1 but it is It is very hot and as I said before by one of the audio output, it is in court, it has 5 transistors that say EK 2030 that I suppose are TDA 2030 and 2 TDA 2050, 2 GBU 808 rectifier bridges and a 7805 regulator, I really don't know what could be damaged to give me this problem

Replace the TDA ICs, because they are sending VCC to the outputs, this means they are damaged. Pin # 4 of each TDA, is the output I put a multimeter in voltage range, Pin # 3 is GND, which ones send you voltage and replace them. It's that simple. Tell me if it worked for you and put me handy up! Good morning

Good day.
