Display problem on Kryster KLED403DC TV

[jeangonbay]

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 that time.

So I gave it up for a while, not finding a solution to put the image right side up.

And so, a few days ago, I looked into it again, and found a firmware from the EXCLUSIV brand, where the display is right side up.

However, I can no longer inject via USB, have to desolder the IC, and program it with a CH341A.

Now the display is right side up, but the display appears to be split horizontally by one pixel (see attachment).

I don't remember if this problem was there originally, with the KRYSTER firmware, or if it appeared later with the other firmware.

And I now have a remote control, which allows me to possibly access the hidden menu MENU+1147.

So, question, is there a way to repair this, via signal masking, or something else ?

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

the first firmware file which it was with screen up down., open it with hex 010 editor, and the last one you have this issue also open with it, and compare both... the value of picture and LVDS depth you will be able to read them in raw value. which it easy to change values via service menu.

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

Try this firmware through the programmer from Inves LED-3914 FHD GR (TP.SIS231.P83 C13116 V390HJ1-P02) 25Q64.

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

This chassis has no settings in the service menu (flip image, change VESA, ...), it requires correct firmware for the native panel and remote control.
