Raspberry Pi -- HDMI question

Hi,

I don't get any output to the screen on my LCD tv. The screen is just black and I have selected the correct input. I do get the blinking green lights and rapidly to. Any suggestions on what I may have overlooked?

Cheers

There are some useful suggestions at the RasPi Troubleshooting Wiki: http://elinux.org/R-Pi_Troubleshooting#Display. I find my display blanks out if TP1-TP2 voltage drops too low.

Is TP1 and TP2 where you can connect a volt meter and test the Pi to see if it has sufficient voltage going thru?

Yes -- there's a nice photo showing how to do it at the RasPi Hardware Wiki: http://elinux.org/Rpi_Hardware#Power_Supply_Problems.

Tested with SD card inserted and tested TP1 and TP2. My voltmeter read 4.84v. So its between 4.75v and 5.25. Maybe it should be around 5.xx?

When I use a composite video cable it comes in fine. Not sure why the HDMI doesn't work though.
