Repairing a TV with a cool hack
"Surprisingly the snooper worked at first attempt. I didn’t even care to check that I didn’t mixed up SDA and SCL. Apparently Murphy had other things to mess up that day."
- CamperBob 17y agoThat is a nice piece of hacking work. I'd lay 99.9% odds on that write-protect pin being left floating. (Which would mean he'll have to go through the same exercise again. He should have gone ahead and fixed it this time.) +1 karma to LG for including that schematic. I will remember that little tidbit of information the next time I'm shopping for a TV.
- joezydeco 17y agoYeah, that blew me away. How often do you see schematics for ANYTHING anymore, much less a TV? Most appliances still include a basic wiring diagram (helped me find a corroded connector in my fridge once), but the circuit boards are usually not diagrammed out.
- bemmu 17y agoNot knowing much about electronics, I was surprised that it is actually possible to write things to the chip without removing it.
