I own a thinpad model # i1200 1161-260. The Lcd works for about 1 to 2 min then begins to flicker and then goes blank. If you tap on the screen the LCD will come back on for a couple more minutes then do the same thing. I had this fixed once before thru IBM Warranty. Now the system is out of warranty and I need to fix this myself. I need info purchasing thinkpad parts and service for the thinkpad. Someone told me this could be an inverter. Do you agree. Or could this be lcd itself.
