Hi all,
I picked up a Marantz NR1501 that the seller said did not produce any audio, but was starting up just like normal. This was indeed the case and the hunt for damaged components started.
After confirming all voltages and replacing all caps on this godforsaken HDMI-board I finally got sound from the AUX input, but all digital inputs are still dead.
The service menu shows no DSP version so I desoldered IC1604 that should have the serial flash DSP firmware on it and made two dumps that turned out identical.
The content of these seems to be useless as far... -
Hello, colleagues!
I'm currently dealing with an issue while repairing a Concord Infinity elevator. The microcontroller P87C51SBPN used in the control board has failed, and I need the original firmware dump in .bin format to replace it with a new processor.
What I've done so far:
• Diagnosed the issue and confirmed the microcontroller is the root cause of the problem.
• The original processor is beyond repair, and I wasn't able to extract the dump.
• Reached out to the manufacturer (Savaria/Concord), but I haven't received a response yet.

Hello all, as the title says, I'm very much in need of a valid firmware dump of a Anycubic Photon 5.5 3D resin printer. It's stored in a Winbond 25Q32, so it's 4Mbyte.
Here's a little background for my request. A few weeks ago I bought this 3D printer from a guy who had moved on to a PLA printer. I got it at a vey reasonable price, as it was in a defective state. The seller told me that he had experienced a power failure during a firmware upgrade, after which the printer appeared to be dead. He thought the firmware was corrupted in such a way that the printer was now bricked. As he... -
Hello,
I'm helping my brother to fix his Blomberg laundry dryer. He called a repair guy to have a look and the repair guy said the control board is faulty. They said the replacement board costs $400. Too expensive! 😨 My brother asks me to take a look. He has checked the door switch and thermal fuse, etc., and those seems fine.
After plugged to mains, there is no display. There is just a clicking sound from the buzzer, like one click per second. No other response.
I suspect the firmware inside the MCU (ATMEGA64A) got corrupted. Can someone in this forum by any chance provide... -
I'm trying to extract firmware from a GoXLR-Mini
https://www.tc-helicon.com/product.html?modelCode=P0DI7
I know it's not ideal, but I'm trying to extract the 64MB firmware without removing the chip. I've done this before, but I realize it's a case-by-case thing. Unfortunately, it seems this board's layout results in it getting powered by my SPI tool (Buspirate), failing extraction.
I believe the issue is the flash chip's HOLD pin unable to get pulled high, as the current for that pin dissipates elsewhere in the circuit. When I try to pull the HOLD pin...
