Toshiba 49U7763DB (Mainboard: Vestel 17MB120) firmware issues after sporadic power cu

[cheeky2]

I have this Toshiba 49U7763DB Tv which was suffering issues after various electrical power cuts, which happened in quick succession
Originally the TV was powering on and then very shortly powering off. I managed to get into the menu structure before powering off and carry out a first time installation of the TV. Which didn't make much difference. I have managed to factory reset (that didn't make any difference either).
The firmware inside the 17MB120 is corrupted and is causing some strange issues so my question is does anyone have any suitable firmware for this model?
Details:
Toshiba 49U7763DB (UK model)
Main: 17MB120 23438049
Screen: VES490QNUS-2W-U01

I can get hold of a same model TV main board for the Toshiba 55U7763DB which uses the VES550QNUS-2W-U01 screen which I am hoping is cross compatible with the VES490QNUS-2W-U01 screen? Can someone confirm this for me please?
I can probably get the screen panel files from it though I will have to trawl through the forum to find the procedure as its been a while since I have played around with this ( I will have a look for the procedure).
Any help would be appreciated Thanks

Try at your own risk. If there are problems with the remote control, use a Vestel or a programmable one.

The panel profile is saved with a folder called downloadpq.mb120 placed on the stick and typed from the remote control MENU/4725/USB Operations/OK.

Thanks for that. I will save the panel files before I try it out.
Thank you

Thanks for replying to me in the other Turkish forum and on this one as well and providing the software it is appreciated. Unfortunately it hasn't resolved the issues, however I have the panel files and will purchase the 55inch version of this board and put the panel files on it.
Does the SPI flash ic on the 17MB120 board contain the details of the remote control codes as the TV is constantly thinking the left hand remote control button is being pressed. It's not the power button/joystick as the unit has been disconnected from the TV. As if it is then I can read the working flash from the other 55inch main board TV and try it in my original board and hopefully get both working
