sub-micom upgrade by mistake

Post by oztoralia »

Hello

I have a samsung UA55H7000 TV, unfortunately last night I entered Submicom upgrade section by mistake and the screen has been stoped working and remote control doesn't work anymore.
I didn't power off the TV yet.

may I ask you send me submicom bin file for attach it to the TV? or guide me about this problem?
by the way before I enabled the submicom upgrade I had attached USB flash with latest firmware to TV. can this help?

my TV info before submicom upgrade is attached

Dear notengo13

Thank you very much for your reply and uploaded file, My problem has been solved, let me explain what I've done to solve this issue:

First of all, I seriously recommend DO NOT ENTER to service mode if you do not know what are you doing! it is very sensitive area and could make your TV useless for ever!!!

Anyway in case of mistaken sub-micom upgrade first try to call Samsung support center and receive advice from technicians, if you don't have access, maybe the following instruction can be helpful.

1-Never turn TV off immediately.
2-Prepare a FAT 32 formatted flash USB drive
3-Download latest firmware from support section in Samsung website. firmware should be compatible with your area or your country.
4-Extract files from downloaded zip file to USB Flash drive, and remove USB from your computer safely.
5-Attach USB flash to the first USB port of the TV and wait at-least 1 hour
6-Remove USB flash drive and repeat the step 5 for other USB ports.
7-don't remove USB flash from last USB port and let the TV be on for 12 hours!
8-Turn TV off by detaching power cord and reattach it after 5 minutes.
9-I hope everything goes well.

I DO NOT GUARANTEE THIS METHOD WORKS FOR OTHER TVS, BUT IT SAVED ME HUNDRED DOLLARS.

Good luck

good to know that you succeed. There are many people which hit submicom upgrade. In service manual there is described how to upgrade Sub software.

I think there has to be manear to revive the TV after you hit that submnicom upgrade and turn off tv. Turning on and pluging correct usb with firmware to tv and let it try maybe will work because some people described that usb drive was flashing and if TV didn't find the files cant upgrade the submincom.

I replied time ago about this on some thread but get no response. so dont know if works or not. I Don't have TV with submicom ugrade failed to try it.
