The command however is not writable. Reading it returns. Ok, nothing straightforward.

Is there a reset button for DP42849 SANYO due to an electric surge? Is there a reset button. Is there a reset button for DP42849 SANYO due to an electric surge. I have a sanyo model dp42849 and i have a issue with no pic or sound black screen no power but power light comes on i removed two screws on back and on the power panel the fuse.

No obvious BOOT pin as one would expect with a device that's not meant to be tampered with. But maybe pulling some pin high or low during reset will get me somewhere. After the first pass no, not really. So maybe we have to set multiple pins into multiple states for it to work. Or maybe there's no such combination at all. How about I try to abuse N/C pins instead. I have no logical explanation as to why I came to this decision.

Maybe I saw a presentation somewhere about blackbox chips and N/C pins years and years and years ago but I could just be imagining things. Either way, about 5 minutes of poking at PIN #28 with a resistor connected to 3.3v in hand and triggering RESET at random intervals while running a continuous command scan. $ smbusb_scan -w 0x16 ------------------------------------ smbusb_scan ------------------------------------ SMBusb Firmware Version: 1.0.1 Scanning for command writability.
