Hello,
My thunderbolt display has a strange problem where the longest it will stay on is 30-40 minutes before shutting off. Sometimes it won't even last that long or start up at all.
Apple identified this as the LCD panel. I believe I can replace the LCD myself but am unsure about which OEM LG screen I can use. I know that the 27'' iMac and the thunderbolt display use the same LCD panel but they seem to be different sub models. Also with the iMacs the replacement panels control board must be swapped out with the original panels control board so that a certain connector will work. What I am asking is if I LM27WQ1-SDB3 or other screens found in the thunderbolt display can be replaced with the older LM27WQ1-SDA2 and same way newer iMacs can be.
