Our customer needs to change from the Sharp LQ64D343 to the NEC NL6448BC20-18D. The inverter is changing from T-Y LS530 to MicroSemi LXMG1626-12-46. We mounted the new parts, with new cables, and what happens is the NEC backlight comes on for a few seconds, then goes dark. We don't know if the LCD itself is actually on, as the backlight is not on. We think the cabling is correct, but not 100% sure. We did test the GCX board with the Sharp to make sure it is OK, and it is.
We offer a panel integration service to modify (if necessary) the board in question to talk to the desired panel reliably.
In order to move forward with this integration, please drop us a line at support.us@eurotech.com with the datasheet for the NEC NL6448BC20-18D panel so we can do an initial evaluation.
