by OmronGuys I have set top box which has no power on in specific case. When I insert antenna plug which has 12V on it because of dB gain device on top of antenna, device if its turned off, it will not turn on.
After I need to open the case and short + and - on ABS10 chip and after that device will turn on, without antenna plugged in, after its turned on I can plug in antenna and it will work fine, but I notice there is some extra heat inside the unit.

by max_smartHi all,
First off, this forum really helped me out by advising me to cut some ribbon connectors to the LCD panel in order to fix a 70" TV (lots of threads on Sharp TVs with this issue). I didn't believe that it could work, but it did.
Now I've been encouraged to try to diagnose something quite a bit more complicated. That is an old T430 motherboard. I work on a college campus so I have access to pretty decent tools. I found the schematic for the motherboard on the site, and have been following traces and taking DC measurements from things. I also don't mind...3 PhotosYesterday, 03:27 PM -
