Hello everyone,
I'm Marek and I'm from Poland.
I bought on our auction site 5 pieces of damaged Marchalla speakers. I'm an electronics engineer and thought I would fix them myself. I was very disappointed with the construction inside.
As power amplifiers there are 2x TAS5711. Everything is controlled by a ready-made module from Frontier Silicon MINUET FS5332. In the attachment I send pictures of the PCB. All 5 pcs have the same fault. The power supplies have 24V at the output. After connecting the power supply from the lab power supply, you can see how the current floats from 0.04 - 0.26A. No buttons work and no signs of life on the front panel. I suspect a software fault.
Please help me in repairing this speaker.
Someone did not disable access to such a speaker and it can be accessed through an external IP. http://59.11.201.30/
