How about some impressive home lighting that started life as a cracked flat screen TV? Posted in Peripherals Hacks, Repair Hacks Tagged 4K, dell, LG, monitor, salvage, trash But if you can keep an open mind, the curb is littered with possibilities. Finally the center section of the LG monitor’s back panel was cut out and mounted to the new hybrid display with a 3D printed frame.Īdmittedly, these were some pretty solid finds as far as trash goes. With the Dell LCD mounted in the skeletal frame, the control board from the LG monitor was bolted to the back and wired in. But if the control board could be salvaged from the monitor, and the working LCD pulled from the Dell…Īfter taking everything apart, made a frame for this new Frankenstein monitor using pieces of aluminum channel from the hardware store and 3D printed side panels. Separately these two pieces of gear were little more than a pile of spare parts waiting to be liberated. In this case, scored a LG 27UK650 monitor with a cracked display and a Dell OptiPlex 7440 “All-in-One” computer that was DOA. If you’re as lucky as, you might be able to mash a few devices together and turn them into something usable. But even the broken gadgets are worth taking back to your lair to strip for parts. You can find all sorts of interesting hardware in the trash, and sometimes it’s even fully functional.

The TV didn’t quite start beeping in a different pattern as we’d expect in a sci-fi movie, but it did notify about a “new USB device” – and started asking for a 6-symbol service menu password instead of a 4-symbol one. By this point, AccessUSB could safely be assumed to be a service mode dongle. A few modules referred to AccessUSB there, and one detour into investigating and explaining WebOS USB vendor lock-in implementation later, they programmed an STM32 with the same VID and PID as the mythical AccessUSB device found in relevant WebOS modules decompiled with IDA. epk format, but liberated with an open-source tool. found the WebOS firmware for the TV online, encrypted and compressed into a proprietary LG. A few service manuals hinted that there’s a service mode you could access with an adapter made out of two back-to-back PL2303 USB-UART adapters – a few female-female jumper wires later, serial prompt greeted our hacker, and entering ‘debug’ into the prompt responded with some text, among it, “Access USB is NOT opened!!!”. They noticed an “Access USB Status” entry and thought the “Access USB” part looked peculiar. In other words, a fairly regular evening. One boring evening, was looking through service menus on their LG Smart TV (Russian, Google Translate), such menus accessible through use of undocumented IR remote codes.
