Plugged in micro hdmi to hdtv now all inputs stopped working

Hey guys,
I recently purchased a micro hdmi to regular hdmi. I plugged it in my television and it recognized that it had made an hdmi connection but nothing was showing up on the tv.
I unplugged it and figured although it had over 30 5star reviews for a 3 dollar cable it must be garbage. I re-plug in my hd cable box and xbox 360 and now no hdmi inputs are working on the television.
I swapped the tv out with my brothers and replug the hd box and 360 and it still isn't working! I have no idea what the problem may be. Could I have somehow shorted the inputs on the 360 and hd box?
I did try and use a new cable on the swapped tv and still nothing! I am starting to worry that somehow my home entertainment system is now shot due to just plugging in my damn phone into my tv, but I have no idea how it would effect my brothers television.

It could be a loose connection/cold solder joint. It may have just happened when you plugged that cable in. Do you have a warranty on the TV?

was the TV on when you did this?

[Q] Acer HDMI - special settings?

I have an A500 with the Acer stock rom on it (3.2), and I'm having problems getting the HDMI out to work. Is there a special setting somewhere that sends the screen output to HDMI? Or should it automatically appear?
I got a micro HDMI to HDMI adapter off of eBay, so I don't know if that's the cause of the problem. I know the HDMI on the TV works because my XBox works fine on it.
I would appreciate anyone's insight into this problem.

Have you tried turning off your tab, plugging in the HDMI cable to both your tab, and TV, then booting up tab?

It should just work as soon as it's plugged in. You'll see a notification that an HDMI display was detected or somesuch. My A500 had a loose HDMI port so it would flake out with the slightest touch. Cables are cheap, so it may be worthwhile to get another cable from a place like monoprice.com and see if that makes a difference. If not, it's either the device or TV. Maybe a friend has an Android phone with micro-HDMI you can test with?

I found plugging into tv first then connecting to tab worked best, before that I only had a blank tv screen... Seems the A500/501 needs the tv connected first, at least mine does...

mine to just works..
WELL it does on my SAMSUNG SMART TV..
ON MY LAME BUT Huge screen SANYO.. (DONT LAUGH IT WAS ON SALE) tv in the living room i have to sometimes plug the cable into the tv.. set the tv to hdmi 4.. IT WILL ONLY WORK ON PORT 4 .. then when i have black screen saying no input found or something like that i plug in the tablet.and all is well..
ALSO PAY GOOD MONEY FOR THE CABLE.. THE CHEAP TINY Connector is not equal on all cables my iconia only works on the gold plated high end cable
i use the same one as i do for my cell phone...
ACER WAS LAME BY PUTTING SUCH A SMALL PORT. there is room in that spot of this tablet for atleast a mini port if not full size I hate micro ports...

I bought a micro to standard HDMI cable (by PNY) last night at Staples and it works fine. I got 10ft for $29.00, compared to the Monster micro 4ft for $39. It worked fine at the hotel I was at on the flat panel in my room. No complaints from me.
I'm surprised at the diameter of the cable, as it is very thin. But, it works! Hellooooo Netflix!
I'm about to try it at home on my old Sony XBR...
Cheers!

I bet he's using a Westinghouse TV if I'm right for some reason the Westinghouse brand doesn't like any android hdmi out this goes for my a500 and my evo. Mine doesn't work and I have had it working with my Sanyo as everyone mentioned just by plugging it in

I also had a problem of not getting my Westinghouse TV, that is only a few years old, to recognize the HDMI input from my A500. Tried everything and it didn't work, but the A500 works on my other three tvs.

I plugged my A500 into an older Sony 52", using the side-mounted HDMI input, and it 'just worked'. Mind you it freaked out momentarily when I flipped the tablet around and the screen auto-rotate kicked in, but once I oriented the tablet in it's normal "upright" (volume buttons on top) position, everything looked great.
On this same topic, I noticed that standard/full-sized HDMI to HDMI Micro cables are hard to find in the retail chain, so I bought mine (dirt cheap prices/shipping and excellent quality) from monoprice dot com.

Really? Huh. Rotation is disabled for me when i plug it into my 25" hanspree
And it 'just works' for me too

HTC ONE OTG not supported/MHL playing up

Any info on this would be well appreciated.
Don't know if this is already covered somewhere but I can't find it. I'm well gutted about this, Just tried watching a film on HTC ONE with OTG cable and it doesn't work. I get a warning notification saying " unable to charge device, please use supported charger " Gutted. I thought this would of been covered since the one-x supported OTG when it got 4.1 update. Also, don't know if it's related but the MHL (an official HTC 1) isn't working properly either as it did on my one-x. It wil be playing fine for 20/30 seconds and then cuts off for 10 seconds then comes back on. It's does this repeatedly which makes what ever your trying to watch - unwatchable.

It supports OTG

Haven't tried mhl, but otg works fine here.
Tried it with my memory sticks and fiio dac.

Seem to be working now. Must of been the memory card adapter I tried, tried another one and ok now but still getting error notification " unable to charge device, please use the supported charger " Don't know what that's all about. Keyboard and mouse work fine with OTG, never tried them before.

Definitely something wrong with MHL.just tried again with official HTC adapter and flawless on one-x, unstable on the ONE.

Isn't the one purportedly MHL 2.0? Maybe the adapter needs to be different...

I just tried MHL on my One using the official HTC M490 adapter (NOT the M500 which I think won't work). I have no problems at all with MHL. It is stable. I don't know what difference MHL 2.0 makes, but I did notice that the phone seems to be capable of outputting something different to MHL out, vs what is on the phone screen.
For example, and I have no idea why, I seem to have a free copy of Thor on the phone under the HTC Watch application (freebie?). I found that when I choose Thor as the film, the phone screen is showing a synopsis, while the TV is showing a still frame from the movie. However, when actually playing the film, both are showing the same thing. Nevertheless it is a good indication that dual screen gaming applications may be possible for example.
Also tried the OTG using a Samsung usb adapter. No problems functionally but I can confirm the misleading error message about not being able to charge the phone. No problems accessing the USB storage though and Gallery automatically will find pictures on an externally mounted SD card.

HTC M500 adapter has 12 pins and was the adapter for HTC tablets (Flyer and Jetstream). The majority of connectors use 5 pins, except Samsung (SIII and Note 2) that uses 11 pin, which allows for MHL and USB OTG simultaneously.
Regarding MHL 2.0, it has the ability to pass 1080p video at 60Hz (up from 30Hz of MHL 1st generation) and charge up to twice as fast. Samsung SIV has it, but I haven't find anything official that shows HTC One also has it, or for the need of a different adapter.

All the MHL adaptors i've seen (mine included- Cablesson) have a micro USB slot so you plug in your charger* to that, then the device to your phone, and it charges as it outputs.
Are you all doing that, or trying to output with no charger attached.

I have no problems but to confirm the adapter won't even start-up if you don't connect the charger...it is totally ignored. I am assuming the original poster either has a bad USB/MHL port on the phone, or the adapter is slightly out of tolerance with its connections hence working on some phones and not others.

I've bought an adapter on ebay for my One X. Besides ths usb charging port having issues, it messed my One X usb port - it only worked with the adapter pluged in. I had to reset One X. So, mhl adapters can be really a mess.

First day with phone today so briefly trying lots of things, I had pre-bought cheap ebay MHL adaptor and tried it with a few youtube videos seems to work OK (confirm you must have a charger micro-usb MHL).
It did give about 20 secs of white snow interference at start almost as though it was tuning in channel but steady after that.
More investigations to follow I think.

How did you get on after more tests?
can you link me to the one you purchased if all worked fine please
if anyone else has a 100% working MHL to HDMI can you post which one and where to purchase.

Sucks that I don't have mine yet. I have two different MHL adapters I could try.

I just experienced the original "HTC AC M490" MHL-Adpater with my HTC One (Stock ROM).
It was working straightaway, but the device display as well as the TV screen where a little bit slow and choppy.
Is it possible to change some settings (like resolution or frame rate) to improve the performance?
THX
Edit: Is it MHL 2.0 ? (Regarding to this thread it seems to be only MHL 1.0)?

No, it isn't.
The S4 will be the first MHL 2.0 spec device.

Is there any way to set the output resolution manually to 720p?

With a custom kernel you can do this. Flar2 did this for the one XL, I see he's starting to migrate over here.

Yes obviously plugged the charger in aswell with the MHL. The picture is perfect. It just play's for 20/30 seconds then cuts out for a couple and just keeps doing that. Even though the OTG works I still get the error triangle in the notification bar, which I don't on my ONE-X, but I can put up with that.

[Q] HDMI woes -- A110 & A500

Hello,
My husband has an Acer 500 that's about 2 years old and I have an Acer A110 that's about 10 months old. I hooked up an HDMI cable from the A110 to the tv the other night, and it didn't work. I've only used the HDMI port twice before, but I have noticed that the battery port is awfully wiggly and frequently when the charger is plugged it, it's often a poor fit and not really connected/charging. Anyway, I did find that if I wiggled the HDMI cable, a snowy picture is very briefly delivered to the tv.
Then today, I discovered that the HDMI port doesn't work now on the 500. This we've used quite a bit. I switched cables, switched to different HDMI ports, and tried on 3 different tvs. Nada. Then I hooked up a computer via HDMI to the tv and it works just fine. So it doesn't appear to be the cable or tv, yes?
I can only conclude that the HDMI ports are a weak aspect of the Acer tablets, but obviously I don't know for sure. The one is still under warranty, I think, so I'll be returning it for repair. But I'm wondering if anyone else has had similar problems or if anyone has alternative ideas as to what might be going on? We haven't had any power outages or anything, and the tablets aren't left plugged into the tv unless we're watching it.
Thx.

Bad hdmi adapter?

I got a hdmi adapter to plug into my n10, bought it from DX.com
It just came, and I can't get it to show up on my TV.
I know the cable and tv work cuz I use it for my ps3. So I plug in the adapter and cable, but there's no signal on my tv.
A few times it went from the blue screen to a black screen and said 1280*720, but I never got any picture at all.
Is this a bad adapter most likely? I'm on a nightly Cm10.1 from a week or two ago.
I was going to contact DX to say it was broken but wanted to make sure. I have no other way to test it as nothing else takes micro hdmi.
Edit: I can't even find the order on my account =/ well it was only like $2. Oh well.

how about an experiment?
I've a couple of questions, mvmacd, and an idea you could give a try.
I'm assuming a) by an adapter you mean a unit (possibly with a pigtail) that's male micro-HDMI to female standard-HDMI and b) that your TV has a standard female HDMI port... right?
And if your TV has more than one HDMI port, you're making sure the TV is set to look for input at the correct port, no?
You could consider taking your tablet and cable(s) to a different TV, for example, at a friend's, and see if it works there.

I think it's a good idea to check the features of N10 (or any other device) with its stock rom or firmware intact, so that you have a baseline reference to compare other external cables or equipment with.
