solved: Finally I managed to restart this TV. I found a FITCO firmware with the right resolution, but with the logo upside down, I then used software, which allows you to invert the image, then I took the opportunity to change the startup screen

why do you say that ? What procedure do you think I can't do?...

the problem is that even the firmwares, whose display is inverted, I always have the problem of offset display which we see clearly on the displayed texts, and I did not have the good idea to dump the original firmware with the logo was frozen

Hello, I will explain all the steps I took:

TV model: KRYSTER KLED403DC
Mainboard: TP.SIS231.P83
Panel info: TY390LK02-ACW1 / V390HJ1-XC01 / V390HJ1-P02 REV C1

So, at first the TV stuckl on the KRYSTER logo, a brand which seems to be sold, apparently only on Reunion Island, the place where I am located.

So I looked for dumps compatible with the motherboard, which I could inject via USB key, with the file name SISEU23X8M.bin.

Several worked, but the display was inverted, so head down, and I did not have a remote control available at...

Ok thank you

In that case, what else could be giving me this problem ?​
