    Emerson BLC320EM9 Blinking Green and shutting off

    Hey guys. I have an Emerson BLC320EM9 and when I try to turn it on, it blinks for about 12-13 times and then the light goes back to red. Nothing is shown on the screen. The screen doesn't look damaged and the guy I'm repairing it for confirmed that as well. When I turn it on, I hear something charging up on the inverter board like a transformer or something and it does make a barely audible high pitched hum before shutting back off a few seconds later. I've searched out this problem and most seem to think it's something bad on the inverter board. I wanted to see if Shop Jimmy had a replacement inverter board but they do not. They do however have a board repair kit here: http://www.shopjimmy.com/funai-1fsa1...repair-kit.htm

    So my question is, how can I troubleshoot what exactly the problem is and is there a chance that this kit will do anything?

    I was going to upload some pics but every time I upload an attachment the stupid forum logs me out.

          Look to see if it has arcing mark on the chassis, inspect the transformers really well.

              I finally got around to testing if anything was grounding out. I did not see any score marks on the power board. I looked for any damage on the transformers and didn't see any obvious signs of damage. I also tested to make sure the wires coming out from the transformers were not grounding out against the chassis.

              I also tested the secondary portion of all the inverter transformers where the plugs are to the backlight and they all had similar Ohm readings. No shorts and no opens.

                  Just wanted to update that since Shop Jimmy got a power board in for this TV, I went ahead and bought one and it fixed my problem.

                      Was wondering if you were ever able to actually trouble shoot the old inverter board by comparing to the working one? having the same issue; the inverter board is sending a "PROTECT 3" error to the main board which shuts down power up sequence. Not sure where to look for the source of the error? any help?

                          Good Day.

                          I just replaced tcon on my sony kdl 65xg9505 and getting green amber leds blinking. all voltages are ok according to working sequence.

                          i downloaded firmware from sony and there is no .pkg fike.. after extracting it gives another file which contains multiple files like inf, payload.bin and 3, 4 other files. i just did that usb but did not worked. anyone knows anything how to do it..?

                          green amber blinking stops after while and then starts again. tv responds to remote control on off etc. before installing new tcon backlite was coming on without backlite...

                          Asus X453MA won't turn on and green led light blinking
                          by jxrepman
                          Hi there,

                          I have this ASUS X453MA Laptop that's not turning on. When I plug in the charger, the green light just keeps on blinking and pressing the power button does nothing.

                          I have checked the charger and it is giving 19+ V

                          I have disconnected the battery and pressed power button for 30 seconds.

                          I tried another RAM stick.

                          Tried disconnecting the keyboard and touchpad.

                          Tried disconnecting the HDD and the wifi adapter.

                          The problem persists.

                          Hope you could help me out on this one. Thank you.

                          Looking for help with a Viewsonic VP230mb where the backlight comes on only momentarily
                          by lostone
                          Hello, I came here after finding some similar questions asked on other monitors and hope someone here can help me get an ancient Viewsonic VP230mp (23" 4:3 LCD) back to working condition.

                          First a little background, I have a background in computer and electrical engineering, and I'm smart enough to know I know nothing about LCD displays and how they work. For this topic I'm as green as they come.
                          When the display is turned on the viewsonic logo displays in the uppper left for 2 seconds then the screen goes black, the power LED is green (on) and when a computer is connected...

                          Toshiba 55U7863DG - green light blinking (17MB130S)
                          by naddaw000
                          Hello, I am trying to bring back to life my Toshiba 55U7863DG, which has never been the most reliable device - keep on annoying me with its slowness and some random start-up/shutdown issues requiring to unplug the AC. But yesterday it finally said goodbye and decided to not turn on again. Green light is blinking, I've seen this behaviour before and thought that these are some temporary whims again, but unfortunately not this time.

                          I have checked that my TV is build based on the 17MB130S board, which seems to be quite popular and easy to buy as a used one. Still I would like to ask...
