SL 220 - PROBLEMS ON TV HD CHANNELS

[Nisio]

Hi !

Good day, I have some problems on my old SL 220. The HD channels are getting frozen and sometimes dissapear the image.

Can somebody give me a help with the previous software image? Now my TV with lastest software VV2.4.55.0:

I would like to :
* Get software V2.1.36 to downgrade
* Get USB files for Emergency Software Update
* Downgrade
* Upgrade

Or if somebody has any other idea, I will be helpful!

Thanks!
