Sharp aquos LC-30HV4U red light on , does not power up , any ideas ?

I have not had that exact problem, I'm sure you have tried powering off for more than 10 minutes, for some reason that has alway fixed my issues with the same model you have. Good luck!

Sharp LC-30HV4U with only steady red lights on Display and AV unit; when pressing vol/chan/power on Display, it will go into "service mode" - what should I check next? and how do I exit service...

If you have lit red lights on your TV every attempt to power ON..
That problem is usually cause of bad power supply board or main board..
