Trying to hook it up to my hdtv but has no picture or sound went and got the cables with the RWY ones on it and still don't work
It has red/blue/green in the back so idk if those are same as RWY

If that don't work do you think getting the HDMI adapter thing would work

Or maybe it's just to old where the insides are ruined would I be able to take it into Gamestop or something where they could hook it up to see if it works?

it's compatible
but it's going to look like shit
buy a tube tv.

No room for those big things lol

Then buy a 27 inch panasonic from 2003 lul

I think you need to have the red white yellow cables.

I got my n64 hooked on my hdtv it works just fine

typically you will have two rows of colored ports on an HDTV if it doesn't specifically have red/white/yellow

You will have Red/green/blue - These are for video signal, if you are plugging in a yellow cable, you want it in the green port(most tvs use this port for both types of cables)

Then you will have a separated Red and white input. This is where you would plug in your red and white, as they are audio inputs. Usually it is labeled as audio.

Ya I tried
Maybe it's just broke somehow lol

Think I might get the HDMI converter if that don't work might get new n64

Most modern TVs do not have composite (red cable, with white and yellow audio cables).

They are not the same as component (red, green, and blue video cables).

I believe N64s only natively allow S-Video, composite, and coaxial (in order from best to worst).

See if your TV has any of those inputs, and get the appropriate cable. S-Video is best but not many TVs have it.

If not you'll either have to buy a new TV (CRT like Sony Trinitron, N64 looks vastly better on CRTs anyway), or else mod your N64 (e.g. http://retrorgb.com/n64.html) or find some other third party solution like adapters.
