Monarch LE-50D3 50 FHD LED TV: Continual Booting Loop with Kogan Firmware on T.S506.81 Mainboard

Hi everyone,
This problem has me stumped. The brand listed (Monarch) does not seem to exist anymore and the model number matches with a contex TV (same description etc). Upon further inspection it seems someone has flashed the firmware with Kogan firmware as this is the logo that displays when the TV is booting. It turns on, displays the logo for about 4 to 5 seconds, turns off, turns back on and this repeats endlessly.

The mainboard inside states that it is a T.S506.81 which seems to be quite common in some brands. I have downloaded one bin file from here but cannot get it to try and flash to the new one to see if I can fix it.

Here are the specs on the back of the TV.
Brand: Monarch
Model: LE-50D3
50" FHD LED TV

Any help would be appreciate in to how I can stop this from happening or potentially fix it.

Thank you all so much,
Regards
Adrian

I have a smart tech file, but unfortunately I don't know if it's working, as I haven't had a chance to test it yet

Thank you. I will test it and get back to you.

I have the exact same problem and managed to use Kogan Agora's firmware but the remote doesn't work so looking to try another firmware. What firmware are you using?

My system info:
ver.31028
TP.S506.81/T.S506.81B

SW update name SIS506BD81.bin

Kogan uses the same SW name but different remote codes so can't use the remote even though the TV works now. Do you have your firmware dump that I can try?

And what is the brand of your equipment?

Did you happen to figure out the issue?

Still can't get the remote to work but the picture seems fine. Figured out a way to connect the audio too but the main problem is the remote.
