    Sharp LC-32SB24U dead except for blinking green light

    I got this LCD tv and it has been opened and damaged by someone (see pic).
    All it does is flash green at the front power led.

    The plastic cap is missing from the damaged part in pic so I don't have a part number.
    Can someone help identify this part so I can attempt to get the power board working?

      That is/was a relay.

          That is what I thought but I never had one open.

          Now I just have to figure out the specs for ordering unless someone can help with that also.
          Board # is: RUNTKA397WJQZ
          (Substitute Parts: RUNTKA448WJQZ)
          part loc.: RL7101

          I found a pic that shows LN on top of the relay but couldn't see the sides of part for markings.

              Can you show the underside of the relay? May not be able to locate exact replacement, but can find one that's good enough.

                  I had trouble getting a good clear pic sorry.

                  Edit: I found a relay on another board from a plasma with the same spacing for soldering but not sure it is ok to use. see second pic.

                      I put the relay in to try and nothing changed. Still getting a green blinking light in front as soon as I plug in the cord. Same thing when I press power button.
                      If you think that relay should work I will start checking fets.

                          You should check the voltage of the relay coil to see if is getting the voltage from the switched transistor or not, then also find out the voltage of the supplying to see if it is 5V or 12V or 24V. The coil voltage of the sub relay is rated at 5VDC.
                          Post good clear pictures of the board both side of the whole board and in small sections.

                              Sony kdl 65xg9505 green amber blinking
                              by shahnld
                              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.

                              Sharp LC-40LE830E white blinking after wallplug is off
                              by bajdik
                              Hello, on Sharp LC-40LE830E is everything OK. Working great. If I put the 230 V off and on again, it just blinking white standby LED. I can power on only via VOL- and CH+ and POWER button on TV. After that, I can power off and power on again without problem (by buttons or remote control) until the 230 V is connected. If i put the plug off and on again, just white standby LED blinking. TV needs three button starting again.. On the first look, the backlight looks great, no darker or lighter spots. Any idea what is wrong?

                              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...
