Tv Tuner Problem

[dasic1]

Ive brought a TV tuner of Commsman a while ago and have had it installed for ages with no problem.

About a month ago (not to sure when as I hardly use it) it just seamed to not work I get no pictcher or sound. I thought it must have just been the antenna but on the weekend I tried the antennas that came with the kit but its still the same.

I went over the wiring and it all seams ok. I hooked it to a TV and still get the same thing.

This is what comes up on the screen

Dose anyone have any ideas of what it could be or is anyone around south east Melbourne that has one that I could swap in to test

Thanks Andrew

I know someone in Adelaide that has exactly the same problem. It just stopped working about a month ago. Can still hear sound just no picture.

Hi Andrew, can you remove it and plug it into the aux input of your house TV?

You will still need to power up your antennas so maybe putting the TV in your car may be easier. That would help eliminate some possibilities.

I'd send you a new one to test if I had any left.

I ran a RCA cable from one of the spare yellow outputs to a TV If thats what you mean?

Got the same thing on the screen.

That's a pretty good test. I'm guessing you don't get anything if you use the remote either, ie does any menu display come up?

I had a less than great run out of these tuners, with more than what I'd call acceptable being DOA or dying within a week of going in. However, those that worked seem to be OK (mine is still good after nearly 2 years).

This is your 2nd one isn't it? I'm sure I sent you a replacement previously. I hope there's no underlying issue with your car's power etc. Did you run accessory power from a fuse up front or take power from the existing tuner?

Ive tried pressing all the buttons on the remote and nothing works. Made sure the battery was good as well.

This is the first one, havent had a replacement. I got power from up the front. IIRC its from the switch that controls the exhaust volume

The tuners are also dependant on the factory tuner working properly. If that fails, then whatever is before the factory tuner, be it the aussie tuner or reverse camera, will also not show up.

It could also be a screen problem.

I had an instance where nothing showed up on my screen, not even the trip computer. I pushed the button on top of the screen to retract it and pushed it again to lift it and it magically came back to life. I powered tuner off the factory tuner as per the instructions from here.

The reverse camera and trip computer still work fine.

I think I will just end up leaving it as I hardley use it anyway.
