Fixing Sharp LCD TV Stuck on the SHARP Logo & Firmware Update via USB

 

 SHARP LCD TV STUCK ON SHARP LOGO

 

 Recently having problems with my 65" Sharp LCD TV ; after a power outage - i found out this problem is commonly related to firmware problems on either the EEPROM chip, or the NAND Memory module on the Main Board (one that runs the TVs software)  

 Apparently, this is very common and has affected many Models of Sharp LCD televisions. 

One of the problems I ran into, is that for my model : Sharp LC65LE654U   the firmware is no longer available off of the Sharp website. Below is the link to the file which Sharp emailed to me so you dont have to go through that.  

Step one, one a 8gb or smaller USB - format it to FAT32]

Unzip the firmware file with WinRar, or Winzip - you can find those in google. 

Move the firmware file to the thumbdrive, not inside of a folder 

rename the firmware file to " install.img " , removing the additional file name characters

 

Now unplug the TV, insert your USB Thumb Drive, and plug it back in and wait. 

 Eventually (sometimes can take as long as 15 minutes) you should see a blue screen with the firmware update progress bar.  If not, something else went wrong probably the EEPROM or a previous flash problem corrupted something.  Mine still had a problem, so in my case I need my mainboard repaired with probably an eeprom replacement.

LC65LE654U   FIRMWARE:

 

Thank you for contacting the SHARP Customer Support Center.

I understand that you are seeking the firmware update for your SHARP LC65LE654U TV that does the classic SHARP logo and reset problem. I sincerely apologize for the inconvenience, and I will be more than happy to assist. The firmware was not designed to fix a lockup issue. However, please see below the latest firmware that we have available along with the instructions on how to manually update the TV. 

Dont use this first link, see my notes below.

 BUT, the file link above that Sharp sent me seems corrupt?  ... so this is another link to firmware which seems a bit larger in file size,  I am currently emailing Sharp to make them aware of this issue.

This file link below appears to be valid, but didn't work for me in terms of throwing my TV into firmware update mode.  Others have reported success with the file below.
