Have you checked for cracked solder joints around inputs?
As you have nothing, i would say it can't be the tuner, as then you would
have composite in on rca.

Hey guys,
I have an Hitachi 50UX22BA projection tv which randomly one day upon
turning on stopped displaying anything from its video inputs.(coax,
RCA, svid, ect) however sound and menus work perfectly! I opened up the
back and gave a look around for leaking/exploded capicitors but did not
really see any. Anyone know what is wrong/how to fix this problem?
thanks!
