Replacement Laptop LCD quality problems

[swb_mct]

I have a couple of Thinkpad T61 notebooks where the screens have slowly aged to dim and yellow compared to new. In an attempt to get back to new screen performance, I have received 4 Samsung replacement screens from laptopscreens.com and only 1 of the 4 is white and bright. The other three are Dim and Yellow when connected to the same computer . . no better than the old screens. All 4 screens are the same Samsung Model Number, but the sticker on the back of the bright screen is graphically a different design so there is some difference in production-runs or factory.

laptopscreens.com has great service and great user reviews. They also appear to be the biggest online vendor of replacement screens. 2 of the 4 screens also have had 1 to 3 pixel issues too (stuck on Red or Blue). Do these high volume replacement screen vendors deal in "seconds" . . ones that couldn't be sold to computer makers. I have a total of 9 Thinkpads, and none of the original screens have pixel issues.

Another screen 15.4" 1280 x 800 I recently bought from this vendor was very bright but has 5 minor pixels issues. It was made my somebody I had never heard of. . . don't remember the manufacturer.

The problem Samsung Screens are 14.1" 1024 x 768 resolution, which haven't been used in new laptops for about 3 years. Could that somehow be part of the problem with getting replacements that perform like new ?

I believe you want to replace the screen with a LED Screen, and NOT a LCD screen... They make conversions kits..

The OEM screens and the replacements I have ordered are LCD with CCFL backlights. I understand the LED is better technology, but my issue is that some of the replacement LCD with CCFL screens don't look like they should when new.

The later model Thinkpad T500 I am using now is also LCD/CCFL and it is Very bright and White

Doing a conversion to LCD (if it was possible) is probably beyound my budget for these old computers.

I am trying to figure out why these replacements don't perform equally when connected to the same notebook. I paid about $80 for each screen, maybe I need to order the screens from Lenovo to get Grade "A" screens . . . but I don't know.
