#1 cocoloco cocoloco Level 2 #1 15 Apr 2021 00:31 Hello Gurus, My led tv is not working. The red light blinks 10 times when I turn the tv on. Then, there is both no image and sound but the backlight is ok. I think it could be a corrupted firmware on the main board. So, I am looking for the firmware of a Vestel 17MB30S model main board. The firmware can be uploaded on the tv with a USB stick. Model TV : TELEFUNKEN - TFL49UHD19BC - Black TV - LED TV TV Manufactured by VESTEL. Panel Model VES490QNDL-2D-N11 Screen size 49 inches Thank you for your help.
