I tried, I now have the led of the mainboard which flashes continuously slowly, nothing on the screen except the backlight, 2 leds in front of the TV.
Is there a file missing in the archive? the INIT_CLEAR.bin? Video : [ATTACH]280526[/ATTACH]...Last edited by Kurtix; 11-24-2022, 12:45 PM.Leave a comment:

Re: TV Toshiba 46TL938 - backlight only/green power light
Model TV is : 46TL938
I tried with your files, I took a FAT32/16Go usb key that I inserted into the USB2 socket
I now have the two LEDs on the front of the TV which light up (power + recording) before I only had one (power)
The led on the mainboard flashes differently 1 continuous flash.
When I plug the USB key into the USB1 socket I find the symptom of the beginning
I tried to press the OK button on the remote but no reaction.
Is there...Last edited by Kurtix; 11-24-2022, 12:31 PM.Leave a comment:

Re: TV Toshiba 46TL938 - backlight only/green power light
Thank you for your answer, the flash goes by USB key? what is the procedure knowing that the buttons on the tv + remote control do not react
I extracted the files on a USB key and I inserted this key in USB port 1, but no improvementLast edited by Kurtix; 11-24-2022, 04:04 AM.Leave a comment:
