G'Day!

Unfortunately, what you're describing is a repair issue. You won't be able to address the problem with troubleshooting. There is a part inside the TV that needs to be replaced. If you're under warranty, this will cost you nothing. If you're not under warranty the cost will likely be a minimum of $200 parts and labor. However, be warned that the cost could be considerably higher.


I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please post a comment if you need additional assistance so that I can help you further.

Hi..

Diagnostic code meaning;

Count if how many blinks at the power:

  • Nine blinks - Replace D 6116 and D 6301 on the "G" board, do not resolder as this will fix the problem temporary. Or Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching regulator on the "G" board or check connections. Make sure the regulator is -12 or -13 (negative).

  • Hope it me helpful for you

    Regards

    How do I fix Sharp TV LC-37SB24U?


    These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

    If blinks continue without any pause, the main board is faulty.
    Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

    Backlight invertor is most likely cause of the problem, in rare occasions defective CCFL lamps could cause similar symptoms. Replace defective parts, reset lamp error counter and you good to go.

    Two light are blinkin' in from panel. and tv


    This seems to be a common problem. I have the same issue. Repair man says its a power supply (he thinks). When the lights start blinking, press the power button on top of the tv (not the remote) and most of the time it will come on and work. I am going to try to replace my power supply and see if that fixes the issue. If so, I will update this post.

    Sharp LC-37SB24U will not turn on


    I can tell you 100% that the problem that you are having will be a service issue. I can also tell you that your limited warranty covers in home service from sharp. Give them a call 1-87-SEE AQUOS(the advantage line that will get you through much quicker). or the 1-800-BE-SHARP and let them set you up for service, sharp will take care of that as long as the purchase date of your tv was within 1 year. If you dont want to go through that, I suggest taking the tv back to where you got it from if they will accept it because unfortunately, this problem can ONLY be resolved through service. good luck & keep me posted

    Power light blinking green,nopicture lc-32sb24u lc-37sb24u


    This same thing happened to me, but not until I fiddled with all of my remotes, trying to see if it was an input issue, battery issue, etc. I finally unplugged the tv from the wall and plugged it back in. Nothing. Then I went to take 5 minute ****. When I finished, the Power & OPC lights were blinking, and out of sync. I pressed the power button at the top of my TV and got a picture.
