I just got my Raspberry Pi in the mail, and went to hook it up to my TV with an HDMI cable. I plugged in the cable (known to work with my cable box), a keyboard, and then power. A light comes on the Raspberry Pi, but no picture.

Is there something special I need to do first? I have the OS on a flash card already and it's inserted.

I found a TV with RCA input, that I was able to hook it up with. I know the OS is fine, and went through the configuration wizard. Unfortunately, I don't see anything on the HDMI side yet.

I had a similar problem with my Pi, when I connected it first time to my tv (a Samsung D5000): the tv did not understand an HDMI device was connected. I have raspbmc as the os.

There are a couple of instructions you can add to /boot/config.txt to tell your Pi to activate the hdmi output when you connect a cable, and to force hdmi output mode instead of dvi. I added these lines, rebooted Pi, and began seeing my raspberry on screen :)

config_hdmi_boost=4
hdmi_force_hotplug=1
hdmi_drive=2

Reference: How do I force the Raspberry Pi to turn on HDMI?

In config.txt

#dtoverlay=vc4-fkms-v3d

this started my system to work. I think only one hdmi output works but I do not care. It has a problem finding which video to use and some people have it start working on its own.

@Trapias's answer is correct.

Another alternative is to uncomment the line

# hdmi_safe = 1

in the config.txt file.

You should also verify the correct operation of the screen, the cable and the Raspberry.

sudo tvservice -p

will turn on HDMI output if it was disabled for some reason. Check out the other options of this command.

I was getting this problem I took out the sd card put it back in again and then turned it on(pluged in the power ) and it worked!

I think that's DVI not HDMI. I know that in datasheet it says HDMI. I'm using an HDMI to DVI cable to get the image on the screen.

Ensure that the connections are all secure.

Carefully, but surely, do this. First-time connections can be difficult. If you push too hard, you may damage the unit. If you don't push hard enough, you may not have a good connection.

Ensure the SD Card is not placed upside-down. (It happens.)

Try re-flashing the operating system to the SD Card.

Good luck and let us know of any updates.

I just went through the whole ordeal and I finally went to the little user manual. It says in simpleton - plug everything in and have the TV on but plug the power last. "Everything" meant: HDMI; keyboard; mouse, and; the micro SD card. Now the last thing that you will plug in is the POWER. This will send the PI to boot. If you do this in a different sequence in the initial power up, it will not work. POWER has to be last thing, after everything necessary has been plugged in.

It had been a while since using my raspberry pi and when I turned it on, the system booted up fine showing the splash screen. After the system booted and I saw the background for a split second,the screen went blank. Thr screen remained blank unless I moved my mouse. The video only displayed in raspbian while moving the mouse after boot. I held shift at boot for recovery and reran install. Problem fixed. No more video issues. This was raspbisn 1.2 as that was the version that came with my device

I tried everything you all suggested without success. Hope this helps someone.

Putting config_hdmi_boost to 9 helped for my old SONY KDL-46W5500m

Download the torrent for the os not the zip. You can also try to wiggle the power cable because it might not have enough power
