Re: Hisense 65H6570F Logo shows then turns off

if the USB stick are MBR mode formasted FAT32 and the file on it in name upgrade_loader.pkg and it didnt work to have screen of upgrade prosees... mean yours TV went to shut down as it had HW issue 100% are led backlight, one or more are defect.

Also, I believe the usb needs to be 4g max.

with hisense vidaa no problem with the usb drive size, i have 64Gb MBR mode Fat32 many hisense firmware for diffrent model on it, the one i need just to rename it to upgrade_loader.pkg

Hello everybody,

I had this Hisense TV since November 2019 (Bestbuy Blackfriday special). Couple of nights ago my dad turned it off normally. In the morning it does turn on, shows the Hisense logo, then the LED light flashes and it turns off. It remains in the same state.

Things I have done:
A. Plug it off and on.
B. Plug it off, pushing the power button for up to 2 minutes, plug it in.
C. Contacted the customer service, They sent me a firmware update, with the file name:
upgrade_loader_no_tvcertificate.pkg
The zip file has this name, if it is of any value:
65H6570F_65A6101EU_L0424
and these instructions:

1. Follow the link above and download the file, [ ].zip. The file will be compressed,
so using a built-in or downloaded (i.e. Winzip) unzipping software, extract all files.

2. Locate the file .pkg. Copy and paste this file into an EMPTY FAT32 formatted USB Stick.
a. Please ensure that NOTHING ELSE is on the USB, ONLY the.pkg file.
b. DO NOT CHANGE OR RENAME THE .pkg FILE!

3. Safely Eject the USB from your PC by right clicking on the USB(on your Desktop or in your My Computer)
and selecting Eject , then unplug the USB from your PC.

4. Turn OFF the TV.

5. Plug the USB in to the TV s top most USB port(located on the rear of the TV).

6. Please unplug TV from wall and plug back in.

7. Press and hold the POWER button on the TV Remote Control,
once you see Software updating appear on the screen you may RELEASE the power button.

8. Please wait and let the Software Update process finish.
a. The Software Update Process will complete without any further user interaction.
b. The Process should take between 5-8 minutes.
c. Please DO NOT turn OFF the TV during this process.

9. When the update is complete, the Software updating Screen will disappear
and the TV will come up as it normally does.

10. Remove the USB from the back of the TV.

I have followed it, the stage 7 does not happen. The TV shows flashing purple line sections on the left of the screen. It turns off and on doing the same thing as long as I hold the power button.

D. I have kept pushing the power button on the remote as I plug it in, no difference.
E. Put the USB drive on the other port, no difference.
F. Contacted customer service again, they said change both the power board and the logic board.

I have access to a multimeter, soldering iron, and possibly an oscilloscope. I can do some electronics repairs but nothing too crazy. I appreciate any and all suggestions.

Thank y'all,
Manny
