Oh, and I also dump the firmware from the unit. I desolder the flash ROM, mostly TSOP48 in these units, and save the binary to my computer. I also erase and reprogram the flash ROM to increase the data retention time. If I get the same device with, let's say, bugged or corrupted firmware, I can reprogram it with the dumps I made from the working device and make the other unit functional again. Forget about contacting the manufacturer for the bin files-they will never provide them. That's why I dump the firmware from the device myself. It's an identical copy of what they programmed into the flash ROM during the digital PCB manufacturing process.
I bought a Funai VHS-HDD-DVD 3-in-1 Recorder, Model: Funai T3A-A8182DB, which had the same mode switch oxidation problem. I fixed it, and now I am reselling it on eBay as refurbished. I bought it for 45 euros, including shipping, and I hope to sell it for around 85 euros.
