TV Out Scrambled

I got a 3.5mm to RCA cable originally intended for camcorders. I checked TV out and when I plugged it in I found that I could hear the audio, but the picture was scrambled. I could see a bit of my wallpaper, but the image was all scrambled. Is this a problem with my cable or my phone?

Try switching between NTSC and PAL in the TV Out Settings. See if that helps. If it doesn't, then I don't know.

Mine was like that too using the cable that came with my old Nokia phone. I tried another cable from my Hava box and it worked like normal. Guessing there is some sort of wire crossed in some that camcorders and stuff can deal with.

Most likely the colors on the cables aren't going to correctly correspond to the colors on your tv, because you don't have a samsung cable that was made for that phone. It'll still work though, just try the three different cables one at a time in yellow (video) jack on your tv until you see the picture clearly. then they other two are audio, could be a little tricker to determine which one is left and which is right however.

He said he could see his wallpaper so his connections are not crossed.
Is your audio nice and clean?
If so my guess is that you are set in PAL format and your TV display is NTSC or the other way round.
If not, could also be that the cable is of the cheaper variety and is not well shielded, or is grounding.

MHL problem (SOLVED)!!!

I received my monoprice MHL adapter, plugged the hdmi cable into it, plugged the power into it and plugged it into my phone. the phone shows HDMI hooked up and my monitor will alternate between showing whats on the phone and going to a white fuzzy screen then back to mirrored than fuzzy every couple of seconds.
I plugged my brothers sensation in and it works fine so I doubt it's the adapter, he is rooted running a custom ROM.
I am unlocked and rooted but running stock rom, T-Mobile USA version.

So I went into T-Mobile and asked about this issue, they didn't know, they called tech support who in turn told them to call HTC. They gave me HTCs number, I called and explained what was going on, HTC tells me the phone ISN'T MHL compatible, that we're supposed to use the media link dongle, which costs about $100.
He suggested I try just a straight up micro hdmi cable to my tv instead.
So an older phone (sensation) has the ability, but this new high tech, best of the bunch phone can't do it, what a bunch of ****.
Edit: OK, I figured out the issue, I was running an HDMI to VGA cable to my monitor, since the monitor is a VGA connection. I then went ahead and hooked it up to another monitor that had a straight HDMI connection and it worked perfect, so VGA HDMI cable no good, straight up hdmi to hdmi works great!
Edit 2: So I just tried the MHL adapter again with the vga HDMI cable, and now it works. It's like it needed one cable to make it work and now it will work with the other, nothing changed except that I tried it another TV.

a HDMI to VGA cable? as long as you dont have special equipment this cable can't be used for anything HDMI is a completly digital standard. DVI is digital + analog so a VGA - DVI adapter is possible, but HDMI to analog is without special hardware impossible.

You are correct sir, my bad, it is a DVI cable. So just replace VGA with DVI in my first and second post.
The cable I have is this one.
Thanks.

Okay. Could be a problem with HDCP.

I'n having this issue too.. still unresolved
My MHL came in 2 days back. Hooking the phone up keeps alternating between what's on the phone and the white noise screen. I have a straightup HDMI cable going from the MHL to my LCD TV.
Any suggestions are welcome

OK, I noticed if i just go and hook up my cable to the mhl the problem comes back, the solution is to hook everything up to the phone, then reboot the phone and the problem will be gone. One other thing is make sure you have your media volume turned up as it affects sound output, so if your media volume is muted, it will also be muted or whatever volume the phone is set at. I thought I was nuts when there wasn't any sound coming from my stereo until I realized that I had my volume all the way down.
DO the reboot thing and it should work no problems, also, our phones don't need to be plugged in to your power cord to use the MHL, so I'm wondering if the MHL adapter is even necessary for us if we can live without the power cord needing to be attached.

Thanks.. Will try and circle back..
Re: The power cord, not sure if it's 'needed' but I'm guessing without external power the phone wouldn't last an hour.
Seperate issue - When I last tried, I was playing around with it and the phone heated to a point it was slightly uncomfy holding the phone.

Yup, without the external battery going to the phone it will drain dramatically. I also noticed the heating issue you mentioned.

Update: So I tried hooking up all the cables to my phone, restarted the phone and then plugged it into the TV. It still gives me same results unfortunately. I get a display but it keeps going away every few seconds and the white noise screen appears.
What a buzzkill... My old phone (Sensation) was flawless in this respect

TV Out and how it works for you.

Since my cable tv got cut, and having no tv/vga out adaptor for my laptop (watching videos while working/browsing/play games is impossible), I decided to go for the TV out on the SK4G. Instead of the vague answers I've seen on here, I found the scientific truth.
Background
Basically, the SK4G has a 4 pin trrs socket that is used for headphones, wired controls, and tv out. While some people have issues using regular headphones (3 pin trs) due to the ground touching the 4th pin (a floating ground can trigger some actions), I have not, and due to the design, they shouldn't.
TRRS stands for Tip-Ring-Ring-Sleeve, as seen on the plug. On TRS, regular stero audio cables, it is Left audio, Right Audio, Common Ground (Mono audio connectors have TS plugs, with Left Audio and Common Ground, backwards compatible with stereo connectors).
RCA connectors on the other hand, are simpler. The prong in the middle carries the signal while the sleeve is ground.
Most TVs still have standard RCA connectors for composite video and left/right audio, and nearly 100% of them have standardized coloring of White (Left Audio), Red (Right Audio), and Yellow (Component Video)
The TRRS connector can be any combination of connections depending on the manufacturer, so not all AV cables are the same. One of the cables I have had TRRS of Right Audio (Red), Video (Yellow), Left Audio (White), and Common Ground.
Most Important part
The SK4G on the other hand, has a TRRS combination of Left, Right, Ground, Video.
What is most important is the position of Ground, on both sides of the cable. If this is in the wrong place, nothing will really work, but if it is, that's great, you can just switch around the rest. Any cable you get must have the TRRS connector with Ground as the 3rd from the top, and that must connect to the common ground sleeves on all three RCA connectors.
Some of the dollar stores around me have a generic brand cable, with a 90º, right angle connector, but it has ground on the 4th TRRS connector, so it's no good.
On the other hand, some have the right cable, with the Red and Yellow switched around. Specifically, it is another generic brand (Sonitek), but geared towards computer cables and adaptors. This one is ""ipod compatible"" (cost me 2.49, has an extra long connector so it sticks out a bit, just make sure it clicks in.). Just make sure you plug in the Red cable to the Yellow/Video connector on your TV. There are other brands with the right cables too. Radioshack's standard av cable is right. The cable that came with my Canon camera released in 2005 as well.
Note: You might need to have no audio playing, and plug the tv side in first, otherwise it might not work.
SideNote: The LCD on the SK4G won't turn off while using the TV out for video, so use your power cable if you want it to last. You can still lock your phone so no video will be shown, but the connection is still on.
And I am on stock (but Rooted and Deodexed) KJ2. Now all I have to do is download a dlna app so I can stream videos to it, as connecting it to upload video is a pity. It does play flv video though with the stock media player.

It's worth noting that the resulting video from the composite output is pretty rough. Grainy, fuzzy, and the image doesn't fill the whole screen. But it's handy for playing nintendo emulators on a TV and stuff.

In Portrait mode, it takes the full height, but only about 20% of the length. In landscape mode it takes the full length, but about 90% of the screen. Granted, it is just composite video, not even s-video, so resolution won't be the best ever, but it's Good enough. If I wanted high res, I'd go waste money on a better phone

Update, yep, tested it out. As long as you leave the 3.5mm cable plugged in and tv out enabled, the display will not turn off. It does dim, but does not shut off. It will waste your battery if unattended/unplugged. You can make the screen turn off by pressing the power button as normal, and that will be mirrored on the tv (blank screen).

Wow, cool. I always wondered what that TV out setting was for. I've seen some cables that have microUSB-to-HDMI which would be awesome, but I never thought it would work (and it doesn't, right?).
FYI: The 4-pin TRRS is also used for GND, AudL, AudR and Mic when you plug in a wired headset. Cool to know it doubles as GND, AudL, AudR, Vid.

Not only that, but the phone can tell the difference. Tried an FM radio app, that needs a headset plugged it, but had my tv cable plugged it, and it told me that. It knew which cable was plugged in.
And yes, no usb video out. No MHL or anything. Just composite video over the headphone jack.

[Q] Possible video out?

I had recently read an article on here (unfortunately I can't find it again) about a certain phone having the ability to display video through a 3.5mm to composite cable. I tried this last night with my blaze and not surprisingly it didn't work. BUT... I switched the rca ends around on the tv because I remembered that using a 3.5mm to composite on an 5th ipod video required I think the white end to be plugged into the yellow port on the tv. So I was changing which cable was plugged into the yellow port and every time I would plug/unplug the red end to/from the yellow port on the tv, the video that I had playing would pause.
I was just wondering if this reveals anything at all, possibly something that could lead to video out through the 3.5mm jack?

I believe there is only audio output to the 3.5mm jack so what is happening when u put that rca in there is its making contact with the audio circuit and just as if u put headphones in and take them out itll pause or music the same with the movie since its only audio to the jack

What you're saying does make sense, I just wonder why it only pauses when I plug in the red end into the yellow port. It doesn't happen with any other configuration. I guess I was a little too hopeful :/. This phone would be perfect if it had video out capabilities.

What can I use the 3.5mm headphone jack for ? Charging ?

Dear Forum.
Most phones have two physical ports : usb port and a 3.5mm headphone jack.
The usb can be used for everything but can I use the headphone jack for anything ?
Example :
The best android tv box is for example my old sony xperia z5 with cracked display. As display is cracked i cant use it as phone but the microphone is top notch for voice controlling my tv if connecting to the sony phone mhl usb port to hdmi port in tv. With a bluetooth mouse/keyboard it is actually better than my win10 slaptop for web browsing considering the plethora of android apps. I have discarded both chromecast and a h96 android tv box as my old sony z5 is way better performing and more versatile.
The problem is charging. When using mhl on a usb ver 2 port(micro-usb) it is not possible charging when output video on same port (only powering the mhl to hdmi port via usb charger) so when looking at the phone I see a 3.5mm headphone jack never used for anything. While manufacturers still equipping phones with the 3.5mm jack Im wondering if it can be used for anything ? (Im considering the behaviour of listening to music all day quite tiresome and slightly sociopathic, Im suspecting some people is using this for shutting other people out). I have seen a "smart button" for 3.5mm jack but it doesnt seem to work when reading reviews, temperature probes with cable to long to have inserted all time and led flash lights to big/to bulky having inserted all time. I have seen a usb to 3.5mm jack but it is unclear how this can be used/recognised by android phone.
What I most of all wishes is to be able charging my phone via 3.5mm jack while the mhl/usb port is occupado when used as android tv =0)
Any tips and ideas is highly appreciated, Iam willing to experiment =0)
Kindly Peter.
