    Sharp Aquos LC-60LE745U Two Long Two Short

    Just recently acquired a nice Sharp Aquos LC-60LE745U that was just of warranty..

    When plugged in, there is two long, two short blinks on the boomerang symbol that just repeat over and over. Screen is black, no indication of power other than the blinking symbol..

    I pulled the back cover. No obvious burns, shorts or bad caps..

    Re-seated all the connections. No change..

    I found some button-combo presses while reading and tried those..

    PWR-INPUT-CHDOWN then plug in.
    No change. Two Long, Two Short

    CHDOWN-VOLUP then plug in.
    The boomerang LED comes on immediately and stays steady. No other change.

    That's where I am at so far?? Don't have much in the way of real troubleshooting equipment. Just a little handheld volt meter..

    Anyone offer some suggestions? Maybe come button-combo I missed?? A listing of Blink Codes perhaps??

    Any assistance would be most appreciated..

    Research has shown that the Sharp SERVICE MANUAL for this model has the error/blink codes definitions..

    Unfortunately, the only place I can find that service manual is a pay site. I have been burned before and don't want to go that route..

    Anyone point me to a link for the service manual??

      When the led.is steady lot.look into the screen with a flashlight. Do you see anything?
      Did I leave the soldering iron on?

        Thanx for the reply...

        Nope, it's completely black.

        No change whatsoever between power down and power up...

          There should be a four pin cable going to the tcon board. Are you getting proper voltages there? The power supply is where this cable feeds from and the legend should be on the power supply to tell what the voltages are.

            Near as I can tell, here is what I have...


            This is the 4 pin connector on the T-Con board


            According to my volt meter, this is where the 2 grey pins from the 4-pin connector end up...


            That's the best shot of the legend that I can muster...
            For clarity sake, I added the 1 and 2 on that pic...

                Re: Sharp Aquos LC-60LE745U Two Long Two Short

                Thanx for the reply R_J.. Much appreciated..

                So, I need to check the voltages on the PD connector, pins 5-6-7-8, right??

                Worst case scenario, the power PCB needs replaced..

                Does that sound accurate??

                Thanx again..

                  That is information from the manual, I have not worked on this model. Here is the manual.

                    Awesome!!! The Service Manual!!

                    Many thanx for that!!!

                    I did a reflow on the power PCB.. Have had some success with that. I am going to install it back on the TV..

                    I'll let you know..

                    Thanx again...

                      No luck on the reflow.. I am going to review the manual and see what is what. If I have to replace the Power PCB, hopefully that is as bad as it gets..

                        Your not getting 12v to the tcon?
                        Did I leave the soldering iron on?

                          Referring back to the pic of the TCON connector above.

                          Near as I can tell, there is 0 voltage on pin 2 and 4.

                              Well, I always like to follow up with my posts and let people know how things worked out..

                              Unfortunately, in this case, I cannot report success.. But not for reasons one would expect...

                              Wanted to thank everyone for the help. Regardless of this disastrous outcome, it was appreciated..

                                        I have the close to the same tv, mine is LC-60LE640U and it blinks 2 and flashes 5 times. I ordered a replacement powersupply which did not fix the error.

                                        I am trying to figure out if the replacement board was bad or if there is some other cause for the error.

                                        This thread is the closest I could find on the interwebs to a discussion on the power issues with these tvs.

                                        Thanks ahead of time for not screaming at me for reopening a 2 month old can of worms.

                                          Hello Sharp TV experts
                                          Our Sharp LC-80LE642U displays one short one long flash error code which is a backlight error. I went into service mode and there were 8 lamp error counts recorded. I reset the count to 0 and did a reset. The last monitor error cause was 16 B00014639:12. 16 is the code for backlight error. I tried to power the tv up but went back into error mode.

                                          Hello,

                                          First of all I am not native English speaking, so sorry for potential mistakes or misunderstanding.

                                          I have a basic multimeter and a soldering iron. No electronic pieces for replacement for the moment, but I can buy some.

                                          I have a Sharp Aquos LC-40LE810E with issue.
                                          When I turn on my TV with the remote control, I have 2 long flashing on the boomerang symbol, and no image/no sound.
                                          I saw in the service manual that I need to click on « menu » button of the remote control to have more information.

                                          Hello, I'm new to this forum. I like to tinker with Sony electronics, I have been lucky trouble shooting sony stuff, But I can't find much info on this Sharp TV.

                                          The problem; plug to power>white led power indicator light is on>it turns on to the red Sharp logo>
                                          then the android logo is displayed, lit fine then the android logo brightness varies, then lit normal, then the tv restarts and does the same startup logos over and over for 5 times then it turns off and the power indicator light flashes the trouble code 3 long blinks plus 3 short blinks .

                                          does...

                                          Hi everyone,

                                          I've got a Sharp LC-55N7000U. It has a standbuy LED when plugged in, but powering it on causes it to blink 1 LONG and 5 FAST. Theres no display and no backlight.

                                          Nothing I checked has that blink pattern for Sharp TVs and there's only one multi-button on the TV itself so that service menu trick involving the input button doesn't work either. Its a post-Hisense buyout TV so that probably makes sense lol

                                          I've tried disconnecting the panel sides from the TCON alternating sides, but no change in behaviour even when the whole TCON is disconnected,...

                                          Sharp Lc-70le734u blinking 2 long 5 short

                                          Just picked up this sharp tv not too long ago and it started not wanting to start the other day, giving me the notorious 2 long-5 short blink pattern indicating a power issue. I was able to force start it a handful of times (once the tv has fired up it has no issue running for 5+ hours). But now as of yesterday, no matter what I try to do button combination wise, I just receive the same blinking code.


                                          So I busted into it and have done the following:

                                          -Removed the power board and inspected for any bad caps, burn spots etc. Do not see any instances of such ...
