What is the LED Driver Board model number?

Hi all,

I have an iMac 27" Mid 2010 model, A1312, EMC 2390 and the screen is randomly turning off after prolonged use/if the brightness is being turned up, which has been happening for the past few years. Research has led me to the conclusion that the LED Driver Board needs to be replaced. In the interest of keeping the computer put together until I repair it, I would appreciate if anyone could tell me the exact model number of the LED Driver Board for my machine? I have found some on ebay with the model number V267-602, but the screenshot in the ifixit repair guide suggests that the model number could also potentially be V267-601. Can I use either board, or does it need to be specific? Thanks in advance!
