Connecting Xbox 360 to TV Without Audio/Video Inputs? Impossible — You Need a Signal Path

You cannot get picture or sound from an Xbox 360 to a TV without a video/audio cable. The console generates signals; the TV receives them. No wireless video standard exists on 360.

Every Possible Connection (Pick One)

Cable	Ports on 360	Ports on TV	Max Res	Audio
HDMI	HDMI Out (Slim/E, some late Phat)	HDMI In	1080p	Digital (in cable)
Component (HD AV)	Component Out (all models)	Component In (Y/Pb/Pr + R/W)	1080i	RCA (Red/White)
VGA	VGA Out (via MS VGA Cable)	VGA In (PC monitor / some TVs)	1080p	3.5mm / RCA (separate)
Composite	AV Out (all models)	Composite In (Yellow + R/W)	480i	RCA (Red/White)
S-Video	AV Out (with MS S-Video Cable)	S-Video In + R/W Audio	480i	RCA (Red/White)
RF Modulator	AV Out → RF Box	Antenna (Coax) Ch 3/4	480i	Mono (via RF)

If Your TV Has Only HDMI

Use Component → HDMI Converter (powered, $15–$30) + Microsoft Component HD AV Cable. Best quality.
Or Composite → HDMI Converter ($10) — worse quality.

Troubleshooting "No Signal"

TV Input = correct source (HDMI 1, Component, AV, etc.).
Cable seated fully both ends.
Try another cable / another TV.
Xbox 360: Hold Y + Right Trigger on boot → forces 480p (bypasses EDID handshake issues).
Settings → Display → Auto-Detect → Manual → pick 720p/1080i.

No cable = no picture. No exceptions. Buy the right one for your TV's inputs.
