And finally, after several try to reset my TV I accidentally triggered MICOMM upgrade.
This is fatal.
Do anyone know where to buy a new motherboard for this TV ?
Thanks

Re: 22F5400 Brick
After a couple of days of googling and studies I found that in order to fix this problem it is necessary to flash the WT61P807 device with its binary dump (https://remont-aud.net/forum/108-49536-1 for my 22F5400).
I found a french people who is available to sell for 20 Euro the flashed WT61P807 with the right FW.
I also understood that a dedicated programmer RT809F would allow the Weltrend flash even without dismounting the device from the motherboard.
I try to keep this discussion updated in order to post my progress and maybe have some assistance and help from forum experts who might have already faced similar situations.
Russian people seems to well know how to fix the issue.
Please feel free to post any usefull information that can help in understnding the fixing process.
