1ch LVDS to 2ch LVDS adapter cable?

[[email protected]]

Hi there. I'm trying to fix up number of Samsung LTN1785W with cracked
LCD screen with replacement LCD panels. I've come across couple of
problems and would like some assistance getting around these problems
with very little costs.

a) I found that the original TFT panel I'm trying to replace (LTA170WP)
takes in 5V where as my replacement panels (2 X LTN170WX-L01 and 1 X
LTN170WA-L01) both take in 3.3Volts.

b) I also found that the LVDS connectors are wider on my replacement
panels. According to original panel's specs here

http://www.samsung.com/Products/Semiconductor/Support/ebrochure/tftlcd/wiseview_200403.pdf)

, the LVDS interface is "LVDS ch1". The vendor who sold me that panel
says that those three new panels are LVDS ch2 interfaces.


What I'm trying to figure out with my very limited knowledge in this
area, is there a product out there that would let me get around two of
my problems I'd indicated above? Any help or direction would be
welcomes and appreciated. Thank you so much.

I don't know for sure, but I suspect that you will be disappointed. It is
probably possible to build a custom format/voltage converter, but I doubt
that the cost would be economic for a few panels. It would almost certainly
be more cost effective to find a source of the original panels. There are
dealers that specialise in this sort of thing.
