lta320wt-l05 may be replaced with T315XW01 VC (QD32HL01)

[mikyva]

Hi to all.
I am a novice in this forum... i hope here i can have some help...

I have two unversum lcd tv:
First have a cracked lcd panel (samsung lta320wt-l05), but have a good board (17mb22-2)
Second have a board 17mb15-3 (have a bad horinzontal synco) with good lcd panel QDI qd32hl01 (same as  t315xw01 VC).

I have read all specification pdf file and the pin assignment are the same (except pin 20 that is reserverd in one and grounded in other) and have the same vcc, but have different power timing...

Can i replace the broken lcd with the good one?
Need a firmware update?

Thanks
