Sharp LC-32SB24U 32 in. LCD TV Logo

Related Topics:

Anonymous Posted on Apr 05, 2017

LC-32SV24U The device was randomly cycling power during use. Not often, but often enough to be noticeable. I updated firmware (successfully). Cycles power fine until turned off for a bit. When first turned on for the day, it is as if the standby feature (what ever keeps the tv warm and ready to instantly turn on when power is pressed) doesn't work anymore. If I just leave the device on, you can see the lights dance a bit and then a single light stays steady. If I leave it a few minutes and then press the power button on the set one time. The light stays on and the set will come on. I'm guessing its a mucked firmware. Am I stuck until the next firmware release?

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
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. .

This is just the beginning, it will happen more often and at some point in time you will have the same problem some of us are having, it will click the monitor power light will lite up green and the ACV box light will come on green for a second and then go red again and the lcd screen will go blue. Unit will not power up. I have this problem and it has started the same way, I did the same thing and nursed it for about 6-8 months now no matter what I do it wont come on, I have tried no power for a day, cleaning, banging acv around tapping, slapping cursing and still nothing. So if you ever find this problem I would love to know what the fix is and who can perform it, I live on disability now and cannot afford just to let somebody charge me out the wazoo and say they cannot find the problem or tell me something like it needs a whole new ACV just because they don't know what to do. If I learn anything I will let you know also.

SOURCE: Sharp LC-37HV4U not turning on

Thank you, psxpirate25!!!! It worked. I had to repeat it about 35 times. It came up in a factory setup firmware mode. I could see the video behind it. Pressing buttons on the remote only switched between the settings menus. I power cycled it a couple of times and had to do another 35 times. Finally it worked! Totally awesome!

SOURCE: The firmware do not finish.. just turn off and

Unplug the ac power cord from the wall for 30 seconds then hold down the power button on the tv, not the remote, and while holding down the power button plug the ac powercord back in and continue holding the power button untill the tv turns on. This is a hard reset back to factory defaults.

Coby phone firmware update

Al firmware updates come with an instruction.

I hope you did read the instruction, before you updated in the first place.
For every update there is a condition, the electronic needs to work perfect and the battery / power supply must be capable of delivering enough power during the whole update process.
When an electronic device is start acting strange, a software update is the worst thing you can try to solve the problem.
If there is an update for your phone, why should I type the instruction here? it is in the package and you should read it before. not when the phone is bricked.

That's the best way to do over your PC to your USB. Create a folder on the storage media in which to save the update data.
Using a PC, create a folder named “PS3” on the storage media or USB device. Within the PS3 folder, create a folder named “UPDATE”.
  • Download the update data and save it in the UPDATE folder created in step 1. Select here to start the download.
Notice
Be sure to save the update data as noted below. If the data is not saved in the correct way, the PS3™ system will not recognize the update data.
  • Location: Save in the “PS3” folder > “UPDATE” folder
  • File name: Save as file name “PS3UPDAT.PUP”.
    Update procedure
Notices
  • Do not turn off the PS3™ system or remove the storage media or USB device during an update. If an update is cancelled before completion, the system software may become damaged, and the system may require servicing or exchange.
  • The power button on the PS3™ system front is not active during an update.
  1. Insert the storage media or USB device that contains the update data in the PS3™ system.
  2. From the home menu, select (Settings) > (System Update), and then press the button
The folder name must be in all uppercase letters.
  • Location: Save in the “PS3” folder > “UPDATE” folder
  • File name: Save as file name “PS3UPDAT.PUP”.

    Press the button to start the update data. Follow the on-screen instructions to complete the update.

  5. Confirm that the update was successful.
    After the update has been completed, go to (Settings) > (System Settings) > [System Information]. If the System Software field displays the version number of the update, the update was successful.
Hint
You can delete the update data from the storage media or USB device after the update has been successfully completed.
