Re: Hisense 65H6570F Logo shows then turns off

for recovery try TV plunged out from wall.. press and keep press power on the TV after first 5 second plug the tv in wall and keep pressing power on TV 15-20 second until you have recovery on screen.. this method used for android TV which it had only power button on it.

you may try it several time

This did not work, no picture or BL or power LED flash or anything. tried multiple times, both with the TV power button (remote batteries out) and with remote. Tried holding the TV power button after plugging the TV too, the original issue of logo happens. Tried holding the remote power button after turning the TV on, same issue.

please don't do any things at this time.. could be dskall thought are correct... however hisense said up to 16Gb but use 4Gb or less will be better with format Fat32 MBR. and insert it at USB V2 (black ) port in the tv not the ( blue ) one V3.

also because yours TV Android which you didn't mentioned about at yours first post... i went in method of vidaa system. so no need to rename.. and use the exact instruction the service send to you..

if the tv didn't accept the firmware after this change.. it could be yours android version the last one.. just contact service and they will send you another recovery firmware.

this why we encourage all when the post to write full information on the tv. as small hiding info will drive us to wrong direction.

I apologize for not mentioning the android TV part.
I tried a 2GB fresh formated FAT32 MBR mode. Same results. BL on one power LED flash no picture, restart, BL on one power LED flash, restart, BL on some purple line sections flashing and moving up and down one power LED flash, repeat.

I do not have any instrument to check the voltages now, That need to be tomorrow. I appreciate it if you can walk me through how and where I need to check for various issues (BL, Logic board, Power board, etc.)

Re: Hisense 65H6570F Logo shows then turns off

These are the pictures of the boards.

Re: Hisense 65H6570F Logo shows then turns off

If it is any help, The power LED light on the tv starts as ON when the TV os OFF, when I turn the TV ON, the power LED light turns OFF, then flashes 2 times before the TV turns off and the power LED light goes back to ON. It tries to do the 3rd flash, but in the middle of it it TV turns OFF and power LED light goes back to ON.

yep, time to take the back cover off and give it a good looking over and voltage testing, seems like backlight issue.

Re: Hisense 65H6570F Logo shows then turns off

you should have joystik not only one button.. mean it can be pressed and push down or up or to side..

It just does not have any joystick, or any other button. I have checked all parts of it.

Re: Hisense 65H6570F Logo shows then turns off

every sytem of TV has had his own way to handel HW failure.

Re: Hisense 65H6570F Logo shows then turns off

I had a Samsung TV where BL LEDs died. It shows picture but no backlight at all. If I put a flash light to it I can see picture. That has been my experience with BL. This is why I am asking.

Re: Hisense 65H6570F Logo shows then turns off

PQI what this mean ??? are you using windows



BL come for just 1-2 second didnt mean they are healthy. its BL issue not Mainboards at all.

PQI is the name of the manufacturer. I am using Windows.
How do I check if the BL is the problem?

Re: Hisense 65H6570F Logo shows then turns off

It is in MBR mode. It is 8GB, I think it is USB 1.0, definitely not USB 3.0.

The Hisense Logo shows up, and the backlight turns on (both for a few seconds), is it an LED backlight issue or logic board issue?

BL come for just 1-2 second didnt mean they are healthy. its BL issue not Mainboards at all.

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.



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

The Hisense Logo shows up, and the backlight turns on (both for a few seconds), is it an LED backlight issue or logic board issue?
