    LG 42lk450

    The picture went out and a guy for them checked out the tv and the said the Main Board went out. Is there anyway to fix it and if so how much would it cost!

    In a dark room, can you see a glow from the screen, or is it completely black?

    You have a digital camera? A digital multimeter / voltmeter?

        Ok. You have a digital camera? A digital multimeter / voltmeter?

            Depends what iPhone, but should be acceptable if decent resolution and lighting capable.

            But you will need to get a multimeter if you want to diagnose the fault. You can buy one for under $10 from many places.

              Ok on the camera, but would I need to get a multimeter when he told me it is the main? Thanks

                I never assume that a tech has properly diagnosed an issue. I had one TV, where I knew what was wrong with the model based on past experience, and the tech's estimate for the original owner was WAY wrong.

                  In addition techs like to simplify things for customers, a "main board" can mean a power board, main (video) board or T-con board...

                    Sony STR-DE445 did I get a faulty IC?
                    by goodpsusearch
                    Hello, I got this AVR for cheap and tried to fix it as a fun and learning project.

                    First the audio video receiver would turn on but had no sound at all, but no "PROTECT" message.

                    So, I opened the metal case and noticed some marks showing that some liquid has been spilled on the amp. Those water marks were found on the main board and the digital board.

                    I disassembled everything, then checked every single cap on every board of the amp and recapped when needed.

                    Also fixed A LOT of cold solder joints and also done some modifications,...

                    Dell E6540 laptop completely dead after dssasembly
                    by max-power
                    Hi, I disassemble my laptop to replace the speakers, to access them, you have to remove everything including the heat sink and fan, unscrew the motherboard, lift it up a bit to access the speaker wire.
                    that was not the first time I dissasemble it, i did replace the same speaker a few year ago and I repaste it last year, so I had nothing to worry about. but when I put everything back together, its completely dead.

                    After a bit of investigating, i found one pin of the status led ribbon cable that was unglued from the cable and bend touching another pin, I bend it back at his place...

                    Schematic Digital Audio mixer RCF type M18
                    by Bektronics
                    Hello dear audio friends.

                    I am feverishly looking for the full electronic schematic (not a block diagram) of the RCF type M18 digital audio mixer.
                    The device does not make a WIFI connection with my Apple tablet and yet I have already installed the recent app on it.
                    I suspect that there is a problem in the mixer itself with the WIFI card and of course I would like to see this on an extensive schedule before opening the device.
                    Thanks in advance if anyone can help me with this schematic.
                    Of course, all information about this digital mixer and possibly references...
