My brother's PS3 on my non-HD tv. We tried connecting and getting different S-video cables but it still won't show up anything. We know the input channel is correct, it just won't show. My brother thinks since his tv was HD it won't connect unless he changes the settings, but how can we do that if he lives three states away? How can we change the setting or atleast get it to show on the television.

It sounds like yoru PS3 has stopped handshaking with your tv. It can happen. It's possible your brother disrupted the connection by unplugging the PS3 before it was shut down. You can try turning on the PS3 first, and then turning on the tv, or vice versa. If that doesn't work, you may need to invest in a cheap HDMI splitter, to plug the PS3 into, and then send the signal from the splitter to the TV. It has happened to me with a computer with the same hardware, once with an LED tv, and once with my surround sound receiver, completely out of the blue. You can try switching HDMI cables, sources, doing putting the tv into maintenance mode and resetting the software. If none of that works, your only option may be to use an HDMI splitter. I did extensive research and read numerous reviews before I settled on this model, due to many recommendations:
ViewHD 2 Port 1x2 Powered HDMI Mini Splitter for 1080P & 3D ' Model: VHD-1X2MN3D
It's available on Amazon here:

Just in case your HDMI cable was damaged when your brother unplugged it, go ahead and get yourself a decent HDMI cable. The Amazon HDMI cables work just fine.

hi
There maybe some problem with your TVs resolution. ps3 outputs full hd high resolution video(1080p) through its HDMI. May be your TV is not supporting that resolution. Connect ps3's component video out to your TV's component video input and then try. if it ask for any resolution selection. select 720p or 1080i, above that resolution your TV will not support. Your tv is hd ready one, not full hd. ps3 's HDMI out is full hd (1080p).
or try this
Connect your ps3 to any full hd tv and then goto video setup of ps3. change resolution to 1080i (down scaling ). then connect to your TV via HDMI. surly u will get the video.
ok

If it works with your Wii and not with you PS3, chances are your audio / video cables were damaged in the move. Try hooking up your PS3 to another TV with the same cables. If you have audio and video on a different TV with the same cables, it may be a problem with your HD settings. If the cables for the Wii aren't HD component cables and the PS3 cables are (or vice versa) this could be causing the problem, as the HD component cables have a different plug in than the normal video / audio settings. If this is the case, search around your TV to find the alternate connections and try those (these will probably require a different channel). If none of this works, I suggest you contact Sony about the problem and perhaps even send in your Playstation for repair. If you need anything else, let me know!

If it's the first time using your PS3, use the composite cables that came with it. Turn on the PS3 go to video settings and switch the input to HDMI. After you've switched to HDMI, turn the PS3 off and connect your HDMI cable, go back to video settings and change the resolution to 1080p. If this isn't the first time you've used HDMI for your PS3, make sure your T.V. is on the correct input. If the T.V. is on the correct input, try switching the HDMI cable to a different input. If that doesn't work try using a different HDMI cable, testing different HDMI connections if you're still getting the black screen. If none of those work then it's probably a problem with the PS3, but just to make sure try plugging something else with HDMI to see if that works. If another HDMI device works, then it's your PS3, if it doesn't then it could be a problem with your HDMI connections on the T.V.

Cable: First you need to be using an HD Cable box to get the HD channels that your provider offers. if you don't, you can't get HD channels. Keep in mind that not all of the channels that your provider offers are in HD. Out of the 300+ channels that my provider Cox Communications in Las Vegas offers, they offer 91 of them in HD. If you have an HD box, you need to go into the settings menu and make sure that your video output is set to constant as you do not want it bouncing between different resolutions when you change channels. In your case you will have two options, 720p and 1080i (1080p does not exist for cable due to the amount of bandwidth required). Choose 720p because your set is under 40" and you won't see a a difference between 720p and 1080i except for that because it's progressive, HD may actually look better. (NOTE: although your analog channels will display at 720p, they are not in HD. They are simply up converted SD so don't expect that they will look like HD channels.) Also be sure to set your audio settings on your box to "HDMI out."
In general, HDMI devices should automatically detect HDMI input but since I don't know what kind of box you are using, it is possible that HDMI-out is disabled in the settings. My box (Scientific Atlanta) doesn't have that option, but I don't know about others. As far as the set is concerned, plug the HDMI cable into the input you want to use (if it's a new Vizio, I'm assuming there are three inputs as that's what my 32" Vizio in the kids' room has) and the set will auto-detect the HDMI input and automatically set the resolution accordingly.
SIDE NOTE: The only other way you're going to get HD channels from cable without a box is if you're using your COAX cable directly in to the TV and that is only if your cable provider has them floating on the line and you're only going to get the 5 major networks and Univision in HD.
PS3: This is even easier. WIth your PS3 powered off and your TV powered on, connect one end of your HDMI cable to the HDMI out on the PS3 and the other end to the appropriate HDMI input on your TV (of your choosing). Power on your PS3. Your TV will automatically detect the HDMI input from the PS3 and put that HDMI input on the screen. You will get an on-screen message from the PS3 detecting HDMI and it will ask you if you want o use HDMI or words to that effect (I can't remember the exact message... it's been a while). Choose "yes" and it will adjust the picture accordingly and should automatically choose the highest video resolution your television can display. To verify your settings, first hit the "guide" button on your Vizio remote control and in the upper right corner it will tell you at exactly what resolution it is displaying at. If it's not where you want it to be, on your PS3, go the Settings Menu and scroll down to "Display Settings" and the first item on the list is "Video Output Settings." Follow the step by step on screen menu prompts to determine your display settings, and choose "automatic" when prompted. If everything is copasedic, the highest resolution your television can display at will be listed at the top (and will be the current setting) and all of the other resolutions will be listed below it. If something is wrong between the "handshake" between the HDMI from the PS3 to the TV and it doesn't display in HD, go back into Video Output Settings" and when prompted, choose manual in stead and set the resolution on the PS3 the highest your TV can display. NOTE: Most 32" TV's have a maximum resolution of 720p fir the reasons I stated earlier. Check your manual for the specifics on yours. Furthermore, all PS3 games are in 720p so even if you have a 1080p TV, don't expect higher resolutions than that. AS far as Netflix is concerned, not all of their programming is in HD. The scale for Netflix is SD/Low/Medium/High/X-High. HD/Low/Medium/High/X-High, your quality depends on the program and strength of your Internet connection.
Closing: I'm a little confused by your issue as HDMI is automatic and you should automatically be getting HD so the only other thing I can think of is that your display needs calibrating and you just think you aren't getting HD. In order to get the most out of your new TV and your PS3, I would highly recommend that you calibrate your set with a Blu-Ray calibration disc that comes with color filters. It will take you about an hour or so to get the hang of and use correctly but the results will be very noticeable. The presets that come out of the box and the settings that they use on the floor in the store are awful and you don't realize how much you've been missing in picture quality until you calibrate. Do not rent this disc from Netflix as it does not come eith the color filters. You can buy a calibration disc at Amazon. I got the DVE one, from what I understand, the Spears and Munsel one is very good as well.

Are you connecting it to a new SD tv after having been connected to an HD set? You can force the system to reset the video resolution settings by pressing and holding the On/Off button after the system has already turned on. I believe it is ~5-10sec. You will hear another beep after the initial startup beep. This will reset video setting to default and go through the resolution setup wizard again.

However, it is also possible that you are trying to connect a component cable to a composite tv. They are VERY different signals even though the cables fit interchangeably. If you use the Green component cable for video on a composite tv you will only see a grayscale image of the picture. This is most likely your issue. If this is the case you will need to buy a composite cable for the PS3 (the PS2 one is the exact same as the PS3 one.)

FYI Component cable has Red, Green, & Blue cables. Composite has Yellow (Video), White (Left Audio), Red (Right Audio). Both are normal RCA type plugs and will fit in each others plugs, but the signals are VERY different.

hook your PS3 to the tv with the regular cord, put the tv on the channel you want. with the PS3 off but switch in on press and hold the power button until it beeps twice then release. you can also do this the other way round (SD to HD).

or the previous owner of the ps3 had the settings on the system on HD settings and now the Non-HD TV cannot recognize the signal. In order to change the settings you have to find someone with an HD TV and switch the output settings from HD to AVI

Hey bro try going down to circuit city, best buy and get the HDMI cord that converts to a Component cable on the opposite end. You can do this as long as the back of the non H/D tv has the Component Inputs on the back of the TV. If that does not work get the HDMI cable that converts on the opposite end to a S Video signal and connect that end to the S Video input on the back of your tv. I have seen these cables at circuit city in the playstation section. Again on one end of the cable it has your HDMI input to connect to your ps3 and on the opposite end of the cable it has the S video plug to run to the back of your tv and plug it into the S Video input. Same thing can be said for the HDMI on one end of the cable and the Component cables on the opposite end to run to the back of your tv. This will work if you find those cables. Good Luck.
