    Sharp Aquos 37" RED blinking power light

    Hi Gurus,
    I hope you can help
    I have a SHARP 37"Aquos LC-37G2x with a TU-37G2X AVC.
    It was dad's and was in storage (cool n dry) for a while after he passed away.
    I decided to rescue it from the dark and set it up downstairs.
    All good worked fine last week with a Digital set top box connected via Component input.

    Yesterday, I went to hook up a Raspberry Pi to it and prior to connection the RED power light was blinking steadily on the panel. When i used the remote to power on, the power light goes from RED to GREEN - relays in the panel click the the power light goes back to red. No backlighting occurs.
    So, i try to power on via the AVC box and same result.

    Now i disconnect all inputs - same result - here's the kicker, I disconnect the factory cable from the OUTPUT-2 socket (as pictured) on the AVC and power up. The panel springs to life and cooling fans whirr in the panel and a info box is displayed on the panel (screen) "Loss of Sync". As soon as I re-attach the Output 2 plug the panel turns off and goes back to red blinking light.

    Any ideas? Is it in sleep mode?
    I have tried as many soft re-boots as i could find on the 'net - Also AVC has 2 hard reset buttons which i have tried to no avail. Am I missing something?

    The picture was still awesome last week for a tv of its age and hope with your help we can get it running again

    Cheers

    Can you and have you connected the box to any other set. Eg S-video output to another set?
    Can you try the DVI output by using a DVI to VGA adapter.

      Hi Dick_Barton

      i have re-tried connecting the digital set top box to the AVC unit. to no avail.
      I do remember (which i forgot to mention in the OP) is that I think i have made an adjustment to one of the sleep settings in the TV menu -Mode 2 i think- I wonder if this is the cause.
      I have also connected the set top box through the DVI-D input (HDMI Adaptor)

      The Panel will not function without the AVC media box (TU-37GAX) and by that i mean allowing to call up menu's etc.

      Oh, i get it - I re-read your post.. I will try this tomorrow morning
      Do you think i may have some form of menu access?

      Will let you know how i go...

      Cheers

        I am unfamiliar with the set. Just thinking tha since there are other outputs why not try them.

          Tried the DVI- output to a computer monitor to try and 'trick' it into life.
          no dice
          There must be something in the output #2 cable that senses the display status?

          Does anyone know if a steady blinking RED power light is an error code or is it in sleep mode?

            I downloaded the owners manual, It seems to suggest there are 3 system cables that connect the av unit to the display?

              Yes RJ, Correct

              Display Output One is the Digital signal (DVI style plug) The other seems to hold all the data signal or comms (output 2) and Display Output3 must be the analog video signals (Composite, Component & SVideo)

                I think your having a problem with the setup box. TV turns on without the box and gives the signal that it can't find the box.

                Can you try to use the tv as a monitor? For example connect it to a hd receiver/computer etc and see if it works?

                  Microsoft Surface Pro (5th gen) model 1796 - no power
                  by PantherDave
                  Hi all!

                  I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅

                  I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

                  The board is daox8cmb6eo and i can't find no boardview or schematics on the forum or anywhere...

                  So i plug in the charger, amber light starts blinking ,there is 3.3V and 5V present, and 2.4V on the power button,board doesn't turn on, no shorts...
                  I've tried flashing the bios...

                  interesting thing is the battery was around 7,8V, and it's 11.1V battery, the mosfet near the battery is open, but not charging,i desoldered it,tested it and it's fine ,but the amber light kept going on the charger so i charged the battery with power supply and got it to about 10.5V...

                  by ipatch
                  hello, �� i have been sitting on some microsoft surface pro 4 tablets for a while now. i was originally tasked with replacing the battery in one of the tablets, and ended breaking the screen and logic board in the process. decided to buy another tablet with the same specs. got that screen off successfully of the second tablet. the logic board appeared good, but i guess i shorted something out in the installation process of the logic which i've read is a common issue if there is no barrier between the logic board and battery pins. all that said, i ate costs of the repair and have...

                  LG 39ln540v - red light flashes twice, no power to LED driver?
                  by russpall
                  Hi there,

                  I've got a 39" LG 39LN540V that's just spontaneously stopped working! The symptoms are - when I plug it in, the red light will flash on twice, then go out, there's no visible picture, and I couldn't see anything using a torch on the panel either. If I press the power button (either remote or on TV), the red light comes on continuously. If I press power again, the red light flashes twice.

                  The TV is using a power board EAX64905301. I've attached a diagram of the power output, I've tested the voltages with a multimeter and I'm getting the following:
                  ...

                  Vizio SV422XVT blinking amber/white power light
                  by What?
                  Good day, hope all are healthy and cozy. I could use some help with my malfunctioning Vizio with a blinking power light. I have narrowed the problem to the main board but not sure what to do next. I guess it would be good to start with what I have done.

                  Problem:
                  I have no image, no sound, blinking power light. (left it plugged in overnight and it was still blinking the following morning). I tried the Vizio recommendations (hold power button for 30 seconds, press reset button, check the outlet is live)

                  Power Board:
                  I am getting 5v only. I have unplugged...
