Hello Here is situation. got hp 6000. when turning it on it shows white screen only. connecting to external display works just fine. disconnected the lcd cable from motherboard and connected to another hp 6000 lcd with cable works just fine. so assuming gpu isnt dead as external monitor works. and so is the lcd + cable as it has been verified working on another display. now im out of options what may be gone wrong. any ideas ??? p.s. friend told me that maybe lvds output is dead. if it so is it fixable?
