Hi, I have a 42PLF4307/H TV and since upgraded to FW 0.87.0 I have an issue with 1080i and 3d activated.

I like to know if it's possible to downgrade FW to 0.74.0 (because there was no problem with this FW).

I can't try because I have no more FW 0.74.0 file, but I suspect TV don't permits downgrade.

Many thanks for reply.
