MHL adapter probs - Xperia Z2 Tablet Q&A, Help & Troubleshooting

I just hooked up one of those Volans MHL to HDMI converter boxes. I connected to the TV but when I plugged in the power, the charge indicator on the Tablet flashed on an off and so did the TV picture. I rebooted everything and made sure I tried an isolated USB power supply. I disconnected the HDMI cable to make sure it wasn't an issue with the tv but the power still flashed on and off.
Any ideas? Anyone had success with this? If it looks like a faulty unit, I'll just get another but if it is a design fault, I'll look elsewhere.
Thanks

[Q] How do i use MHL?

Hi guys, i bought the MHL adapter from T-Mobile's website for the Sensation 4G (i have an Evo 3D). I set everything up, plugging the MHL adapter into my phone, standard HDMI into the adapter and TV, and the usb cable into the adapter...
After plugging everything in nothing happens. I even tried playing a video and nothing occurred. How do i activate the video out? Do i just have a bad MHL adapter?
A few questions. Does the battery icon on the phone show it is charging? This means that power is going to the adapter and to the phone. If not, try changing power adapters. If the charging icon is there, then try changing HDMI cables. If this doesn't work, you might have a bad MHL to HDMI adapter.
with your tv off, plug your mhl adapter into your phone, plug your power cable into the adapter, turn your tv on and bam! (note that the hdmi doesnt display the lockscreen)

My lockscreen shows and boot animation , Also to OP ...the hdmi mirroring is not as stable as HDMWIN is for the OG Evo imo, i had to play with it a bit to first get a picture on my Sammy (unplug/replug/reboot etc.)...then i got pic without sound (OG worked w/audio), ended up running hdmi through my Yamaha amp and that worked. Still not as stable as my 4g evo....LAME
btw I've read usb can't be plugged into pc for powering, must be plugged into wall adapter

my macbook pro powers it fine. weird.
I was using it with my stand that had a video on/off button to turn the display on an off. Everything was mirrored fine but I had no audio and hulu was intentionally shutting off the hdmi before any video played. Are they blocking media streaming apps from displaying through the mhl adapter? Oh an i powered mine by pluging it into my ps3.

Funny that you ask this. I just got an MHL adapter off of Amazon that was just the adapter itself (micro USB one end, female HDMI on the other).
I connected the HDMI cable to my TV and MHL adapter, then I connected my MHL adapter to my phone. Last but not least, I connected my power adapter directly to the MHL adapter and my phone started charging.
The input should be immediate from your phone but if it doesn't, check the following:
1. Make sure your TV is on and the input is selected for the proper HDMI port. If nothing is detected, the TV should report that it's receiving no signal.
2. Make sure the power cable is plugged into your MHL adapter. From my experience, it will not push out the HDMI signal without external power.
3. From my experience, you have to connect your phone to the MHL adapter LAST. NOt sure why but if everything else checks out fine and your phone still isn't pushing out a signal, reconnect the phone to the MHL adapter. You should get an HDMI icon on your top bar.
I have the EVO3D stock.
Everything works fine for me (pictures, music, video) except Netflix. For some reason Netflix looks extremely pixellated. Not quite sure why when everything else looks fine.

help troubleshooting mhl adapter please?

Just tried watching a movie on my phone on the girlfriend's tv and got nothing... it's really annoying me now too.
-Plugged hdmi into each of the 4 ports on the tv in case was a bad port
-Tried 2 different phone chargers into a power strip AND tried extension cord from wall (nothing was open directly in the wall)
**Got nothing from those steps**
-Plugged adapter in to pc monitor with hdmi input and charger directly to wall, got picture
-Plugged hdmi into dvd player to test the tv, got picture
My first thought is the charger isn't getting a good connection to the powerstrip because the plug in front of it kinda prevents it from going in all the way - HOWEVER the phone does receive power and charged through it.
But that's why I tried an extension cord right off the wall, so not sure what it could be.
Does the TV have to be newer and support an mhl adapter? I thought you had MHL which required the TV to support AND then there was the adapter that worked with all hdmi (thus it being an adapter).

usb>mhl>hdmi>hd tv issues.

Picked up the mhl converter at a T-Mobile shop, grabbed 6' of hdmi cable, hooked up the phone to my newest tv, and "no signal" bounced all over the screen.
Mocking me.
Hdmi 1
Hdmi 2
Hdmi 3
Nope, zippo.
Dead USB? No, the USB>TV worked for pictures and file browsing.
Faulty MHL adapter? No way of knowing.
Dead HDMI TV inputs? All 3 on a 2 week old tv? Possible.
I called technical, and they were stumped as well.
I have 2 units, and neither worked.
Am I missing something?
Operator error is not unfamiliar to me.
Thank you.
Plug the mhl to power and tv first. Plug the phone last

Tried it, no luck.
I tested mine out to see if I could re-create a no signal and the olny way I did was when I set the signal to HDMI on the tv first, then plugged in the mhl. I guess it needs to have that signal there first to pick it up. Anything else I tried, different configurations of plugging in worked.
Does your mhl have a micro usb plug to charge as well as the hdmi plug? I have a generic one off ebay that has the short micro usb pigtail for plugging in your wall charger into the mhl and also a short pigtail for the hdmi plug. I have read a couple people were having problems with the one that's hdmi out only
Well, I solved the first problem.
Thank you everyone that assisted.
Now my only problem is that I paid real money for the kit.
I do not advise purchasing.
The output is horrendous.
I tried my vids/pics, youtube...no netflix yet...everything was pixelrama.
It should have raised flags that not only tmo tech, but 3 stores in the area are completely unfamiliar due to nobody buying them or trying them personally.

Flyer MHL adaptor for HDMI

Hi,
today i recived the MHL adaptor. After conecting HDMI cable, USB for power suply i had no pic on screen. The icon was there for "charging" so obviuslly it was reciving power but no pic on TV.
Do i have to enable something or...?
Thx!
Mine had/has issues as well.
Nothing you need to activate. It's supposed to be automatic. Try plugging it all in, and then rebooting your flyer. I believe that was how I got mine working initially.
try a different HDMI cable. the adapters can be finicky about that
2 diferent HDMI cables; TV , MONITOR, no luck no where
maybe you got a bad MHL adapter.
Also, I hate to ask a stupid question but starting at step 1.....
Is the display set to the right HDMI input?
http://www.ebay.com/itm/White-Micro...ccessories&hash=item3cc372f48d#ht_4297wt_1396
the above link is adapter and yes correct Display HDMI.
Did you try rebooting with hdmi connected? I had one flyer work as soon as pluggin in, another needed to be rebooted the first time I connected HDMI.
Ok working; what i needed to do was not onlly REBOOT but POWER OFF and back ON wheil stil conected. Now works ok.
Thx guys!

HDMI Cable

I purchased the Amazon Basics micro HDMI cable (http://www.amazon.com/AmazonBasics-High-Speed-Mini-HDMI-Cable-Ethernet/dp/B003ES5ZR8/ref=sr_1_1?ie=UTF8&qid=1419968500&sr=8-1&keywords=mini+hdmi) and I've been having issues with poor or no connection. The first time I connected the tablet everything was great. I played about an hour of Portal with no issue. I had to reboot the tablet, and after that I couldn't get a signal. I tried the HDMI cable in my Canon 70d and had no signal. I assumed that the cord was bad, but last night I tried again and got a good signal for about ten minutes. I had to change the source on the TV and when I went back to the original input, my signal was gone. Has anyone else experienced this with the Amazon HDMI cable or any other HDMI cable? What are some good low-cost HDMI cables that others have had success with?
Ive used this adapter a few times without issue. http://www.amazon.com/gp/product/B00IZYIYX8/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 .. If the cable is giving you an issue with multiple devices can it be the TV?

I plugged the cable into all of the HDMI ports on the TV and one on my Sony receiver. It seems to react the same way with both devices. But that adapted you linked looks pretty slick.
Sounds more like a bad cable than anything else. If you replace the cable and it continues then the shield would be the next more likely culprit. I haven't heard of this happening to anyone else, though.
