Re: lg 42 pj350

disconnect the main board put a 100ohm resistor in the auto_gen of the tcon

plug it in if you get test patterns you have a bad main board


oops never read fully had the same kinda issue except i coudln't get it fully on, when it's on do a update vis usb, sounds like corruption in the firmware

Re: lg 42 pj350

Why would you do that?! Interrupting main board firmware update will brick a main board - You will need to replace the main board now.

It's Murphy's law. Always bites you in the arse at the right time. I would never update firmware on an "unstable" TV; it's just asking for trouble. Only a few TVs can recover from a bad firmware update. I know Sony, Vestel and some Sharp TVs can. But most cannot.
