Dell Vostro 1720 LCD compabilitity problem

[ex250]

Hello, maybe this was asked or solved somewhere but could not find anything related searching.

I have a Del Vostro 1720 with a failing lcd pannel, with vertical lines appearing, decided to change it for other working pannel, but none I tried works or offers image, keep blank no image or double imaged.

Tried this ones:

B170PW06 AU optronics
LP171WP4 TLB1 LG-Philips
LP171WP4 TLN1 LG
N170C2-L02 Chi Mei
LTN170WU-L2 Samsung

I think is that the bios or something has blacklisted them, seems that only works one from other dell laptop, hard to find or expensive.

Is there any way to make one ot this work?, I know, I had spent many money in pannels yet...

Thanks!

Its the EDID 24C02 chip on the panel that needs programming.The dell part number is included on these old panels to whitelist them.Ive posted a B170PW06 dump in the EDID thread,program it and it should be working .You can desolder the chip or use an old LVDS cable .See posts #6 and #57 https://www.badcaps.net/forum/showthread.php?t=74729
