Seen these on TradeMe for about $12. Does anyone know if they'd work ok with an Andriod TV Box ?

 

Need to use at times with a TV that has only A/V inputs.  Seems the cheapest solution and picture quality isn't critical (as long as you can see it, is ok!)

They will work. It will be ugly. Is the TV widescreen? Because otherwise you are going to see everyone tall and skinny.

Thanks. It is widescreen.  I see there's 2 on offer , a black one (slightly dearer) and a white one.  Is one better than the other, do you know?

No idea, that case design is shared among many copycat makers of them. For the price they are its worth just buying one and seeing.

 

I did get one ages ago which didnt have a scaler, so the source had to be forced to 480i for it to output anything, which not everything will do. That one didnt say 1080 on it, the others I got do have that and will happily take 1080p60 and output either pal or ntsc depending on the switch position.

Could be a timely warning to anyone else. Don't buy this thing - it may not work!

 

Tried it on the M8S TV Box - nothing.  Then a Dish T1020, there was audio but no picture.

 

Presumably all USB ports can power it? I tried both the M8S and the TV USB ports... no change. Then on the Dish

 

it's own USB/HDMI. There was audio with no USB, which increased slightly in volume with the USB plugged in.

 

 

 

The offending 'Made in China' gadget is a "Mini HDMI2AV". . There's black and white versions, not sure of the difference, this one's black.

 

I suppose it's conceivable just this one's a dub...

Try it on a computer and set that HDMI out to 480p and see if it springs into life. Does it say 1080 on the box itself? That was missing on the useless one I got. Otherwise identical.

Yes, the outside of the box says "FULL 1080p" !  And there's a spec sheet that gives various HDMI input resolutions:

 

640x480@60Hz

 

800x600@60Hz

 

1024x768@60Hz

 

1280x720@60Hz

 

1280x1024@60Hz

 

1360x768@60Hz

 

1600x1200@60Hz

 

1920x1080@60Hz

 

480i/480p 576i/675p @60Hz

 

720p 50/60Hz, 1080i 1080p @ 50/60Hz

 

Audio worked on the Dish, but not the Android box, but that may be semi-intelligent as it switches itself off with the TV (lack of a signal path?)

 

 

 

When you say yours is useless, do you actually get a picture ?!!

 

$25 down the gurgler (could have been worse!) and I can't even complain, TradeMe offer no way to contact the seller. I flicked them an email but nothing heard.

the non downscaling one is useless because so few devices will output 480p/480i - my NVR which I got it for refused to, android box had the UI in a total mess when it changed down from 720 to 480.

 

I cant recall how they deal with HDCP, so perhaps that is whats blocking the dish box?

Not sure what you have actually got but I bought something similar off Aliexpress for a couple dollars. It had composite and s-video outputs. It sort of worked okay after I figured it out. There was a tiny, tiny pushbutton switch on one side to change the output configuration. I had to cycle through NTSC and all the PAL variations before I finally got a picture. The mini-usb connector was shonky and I had to pry the unit open and solder the cable to the board to get it stable. After that it worked okay and the picture quality was reasonable but for some reason I had to replug the usb every time the HDMI was disconnected, which happened a lot since I was using an HDMI switch. It was interesting to play with but of little practical value. I got it mainly to please someone who wanted to be able to record HDMI on a DVR.

I suspect you have purchased a unit made for the American market. Not a problem with newer TVs here as they will cope with both signals. But if you have an older TV, which seems likely if it doesn't have an HDMI input, then it will be expecting an SD signal that conforms to the old NZ standard - ie, 576i, PAL and 50Hz.

 

Pretty much all of the resolutions listed above are 60Hz, which is the old American standard, so I suspect that rather than being defective, either:

 

  • the unit is choking on a 1080/50Hz, 720/50Hz or 576/50Hz input signal, which are what most NZ source devices will be producing but aren't on the list of its supported resolutions above; or
  • the unit may be coping with the input but is trying to feed your TV a 576i NTSC 60Hz signal, and I wouldn't be surprised if an an older NZ TV can't cope with that signal (some will, some won't).

First step, check that the source device is set to feed the HDMI2AV converter a signal that matches one of the resolutions and frequencies above. Then, if it is, see whether you can try it on a TV that has AV inputs and accepts American resolutions and frequency rates.

Hi Jimmy, that was good advice!  I haven't got much control over what I feed it. I tried 3 different devices they were all output to Panasonic TH-42PV30 (now 14 years old but going perfectly!).

 

So I tried it on our newer 55" TV (but that has HDMI inputs) and yes, now there's a signal.  Only b&w though.

 

There's very little on output, just says "CVBS Output PAL, NTSC_M and NTSC_J". There's a PAL/NTSC switch but it has no effect.

 

Guess it's hello rubbish bin, and buyer beware!

 

Rikk, this seems different to yours, no switching as you describe or A/V inputs.

 

Here's a clip, mines black but otheerwise identical to the first one he describes.  I'm not trying his fix as I doubt it'll work on the SD TV.

If you watch an NTSC signal on a PAL TV, the colour information is missing so you see it in black and white. Sounds to me like your device is not switching to PAL signal. If there is a setting on your modern TV to switch to NTSC, try that and see if you get a normal picture.

I can't see any setting for that on the 55" Panasonic.

 

From the YouTube clip, his PAL/NTSC switch wasn't soldered in correctly, mine could well be the same. But if it won't work on the older TV it's no use.

Older TV is likely to have PAL/NTSC options.

Yes, it does.  I've just tried all/every combination but nothing (except audio).

 

Thanks the the tip though..  may well have worked...
