    emerson 32" lc320em1

    I have a emerson lc320em1 that flashes a green light the screen comes on for about 2 seconds then shuts off and the red standby light comes on. all the caps look good. If i unplug the video board the tv still flashes the green light 10 or 12 times but it stays on. Any help would be greatly appreciated.

        This was actually the first TV I fixed in my foray into TV troubleshooting. Mine wasn't powering on at all. There are 4 or 5 diodes on the power supply that are notorious for going bad, could be your issue as well.

          Trying to upload some pics of the boards but I keep getting a server error. I will load some by the end of the day. I do have a dmm but it's dcm it will test ac, dc, continuity and amps.

            I do have 2 new boards for the tv but they are not an exact match so they don't work but I was thinking I have to good doner boards they came out of a tv with a cracked screen but they did work.

              Found this today, not sure if it helps.



              Seems to be the same model.

                Looks identical on the outside but the internals look different. It could be the same issue I will test the items he described in his article. Thanks for the help

                    Still can't figure this tv out . Still turns on for 2 sec and shuts off again. Any help would be great thanks.

                      could be a bad capacitor.

                        None of the caps look bad and if any were in question I replaced them. If I disconnect a ribbon cable between the power supply and the video board it will turn on and stay on but no picture. That's the only wire I remove and it works without picture

                          This seams to be a common problem with this model tv. I find it hard to believe no one has figured it out

                            Need pics and P/N's of your boards. I have one of these that has the PSU/Backlight inverter all in one.

                            There were numerous failed diodes, resistors, and a mosfet. When psu failed it damaged mainboard also.

                            I got lucky and found both boards from a seller on ebay.

                                  Check the inverter wires for shorts circled in red.

                                      No shorts, tested all one at a time and they all light up individually and all at the same time. I have not done an ohm test on the inverter transformers. Your talking about the black square with copper coils right.

                                          Im hoping someone might be able to give me some idea of what may be wrong with my Monitor Audio RSW12 Sub.

                                          Ive owned it since new in around 2002, so would really like to keep it running if I can, it was the first ‘decent' bit of audio equipment I ever purchased and is a little sentimental.

                                          The issue I had was that it would power up with the red light, but sometimes the green light would not come on and I would get no bass from it. If the green light did come on though, I would get sound out of it.

                                          Hi

                                          I have an 820-2610-A motherboard that has no green light.
                                          I have noticed is when I do a SMC reset the light on the Magsafe blinks.
                                          From My understanding, the sys onewire circuit is responsible for the green light on the magsafe
                                          The sys onewire circuit on this model and others is more involved
                                          I was hoping if anyone knows about this and how it works, can reply and let me know
                                          I know this is an old model but I am sure there are people who still works on these or knows about them

                                          Hi,
                                          I'm facing this issue since this morning. When I try to power it on, the CAPS lock light flashes 7 times (or 6 if not counting the first one when the power button is pressed). The charging light is always on as if the laptop was connected to the charger. The issues started gradually where it would flash the light but after trying multiple time it would power on. I tried to open it and I noticed one coil "1R0 2127" gets hot when the charger is connected. Note: the charging light directly comes on when the battery is connected or the charger is connected.
