New LCD screen issue

HI

I've just installed a new LCD screen to my Samsung NP700Z series , due to me foolishly stepping on it and damaging the old one, but upon powering my laptop with the new screen fitted, all I get is a constant rotation of colored screens (white red green blue blank - starting as soon as i power up), ive checked all drivers are up to date, attempted changing screen resolutions, reseated RAM and CMOS battery, but still no change. I know the connector is working OK because when i reconnect the defective screen i still get an image (albeit damaged).

The model number of the old screen was LTN156kt06-801, so i ordered one with the same number, however the new screen which came has the model number of LTN156KT06. I realise model numbers sometimes change slightly but are still compatible with older models, so im not too sure if its a product problem or compatability problem.

Any help/suggestions on this matter would be much appreciated.

Thanks

Probability is a compatibility problem. With those part numbers you have to be exact unless they specify they are compatible exactly with your number.

 

I wonder if the new panel has a different display resolution. There was the case of someone who few months ago who changed their panel resolution on a Samsung notebook and discovered that the resolution was coded into the BIOS rather than detected by the computer during the boot process. They then discovered that Windows used the BIOS data while Linux interrogated the display panel and was able to use the panel. That member then manually changed the BIOS to suit the new panel.

Wow, coding resolution to whitelist displays. Man that OEM wants to be sure they get their money for the upgraded models.

 

My suspicion is that if Samsung intended to use only one display resolution on a notebook then hard-coding this into the BIOS would fractionally reduce the boot time because the BIOS wouldn't need to interrogate the panel.
