Re: Sharp LC-70LE757U Flashing 2-5 :-( can it be saved economically?
This simply means that the address IC that is built into the panel that addresses that particular section that you are unplugging has either shorted out or has a bad connection to the panel itself in a way that is overloading the circuit and causing overload condition on the tcon board which is in turn shutting the set off. If you can run the TV with that connector unplugged with the picture condition that it has then let it go like that and the owner would just have to deal with it or chalk up to a new TV. Honestly I think you're pretty lucky with having it working in the condition its in right now. I definitely give you props for trying. Sharp panels in sharp television's are really finicky with voltage fluctuations they always shut down with the 2-5 code.
Especially cracked panels they hardly ever function and sharp TVs they always give a 2-5 code because of an internal short.
I should also note that the reason you still have a picture with that one unplugged is because the left side is now doing all the work so expect premature failure of the left side tab drivers sometime.
