I have run a second TV via a Triax link with no problems for a couple of years until a few weeks ago when the signal became intermittent; i.e. it would be ‘on’ for a couple of seconds then just white noise on the screen for a few seconds then ‘on’ again and so on. The ‘main’ TV operated as normal. Checked all connections and, in some desperation, bought a new Triax link which completely cured the problem for 2 or three weeks but now it is back again and exactly the same. Would appreciate some ideas on what might be wrong please.
Hi welcome to the forum. Possible reason is a faulty connector most likely a Belling Lee connector. The Triax uses the coax cable to transmit 9V DC so it’s important the coax plugs are correctly fitted with the core conductor properly soldered.

I tend to always use f connectors and the appropriate Belling Lee adaptors when needed.
Thanks for such a quick response Graham. The only Belling Lee connection is the one which goes in the back of the second TV and which came with the Triax kit and that looked OK. However you did put me on the right track as I rechecked the F connections too. Hard to see if anything was wrong but just screwing them in and out again appears to have done the trick so it’s obviously something that needs keeping an eye on. Thanks again.

You are welcome.
Problems with f connectors are rarer than Belling Lees but of course they can also be an issue.
Often if screw on f connectors are used and a wrong size for the coax outer is used they fail to grip the cable correctly. They should very hard to screw on if correctly sized. WF65 cable can sometimes cause problems because of the thinner core conductor failing to make good contact.
Ah, I spoke too soon! Problem returned yesterday and I’m pretty certain connections are now OK. Can you think of another cause Graham? Thanks for your help.

Assuming you have a terrestrial aerial into the triax rf1 in. Do you get your HDR1000S picture back if you remove the aerial input ?
I should have told you that I have a Freesat Humax box which feeds the Triax box via a scart lead into AV input. Don’t have anything in the RFin socket. Thanks again.

If you remove the magic eye from the remote end of the tri-link cable and plug the tri-link output directly into the TV can you now see the box output ?
Can you plug an aerial into rf1 in and does your remote TV have a digital freeview aeriel ?
Thanks Graham. Bypassing the magic eye made no difference and then it was OK again; that’s the problem with an intermittent fault I guess. Don’t have another aerial for the second set but swapped it for the main one and that was OK. I know a bad connection still seems the most likely so I’ll get some new f connectors and let you know.

The Triax is designed to allow your main aerial to feed both TV’s. You connect the main aerial to RF in, the local TV to RF1 out and the remote TV with the magic eye to rf2 out. You then need to choose a UHF channel for the triax outlet that doesn’t clash with the ones your local terrestrial transmitter uses. That way you can independently view any Freeview channels your aerial provides.
Hi, I have had the same intermittent problem using a Triax Tri-Link connected via 2 x coax cables to two remote TVs via a passthrough compatible rf amplifier. The picture on the two connected TVs is sometimes ok but then intermittently flashes between excellent picture to white noise. I am now on my 3rd Triax- Tri-Link , the first one went faulty after about 12 months, the second one lasted about a month and the latest one now exhibits the same problem after about 2 weeks use. If you look on reviews on the Amazon Uk website you will realise that we are not alone. By the way I do use the Rf Aerial signal and this is always ok. It is just the modulation of the Triax box that fails!! I have now given up with the Triax product and returned the third one for a refund. I have now installed an alternative product with exactly the same functionality as the Triax product. It is a Labgear DigiLink MRX700. Available from Amazon Uk It is not physically as solid as the Triax product but so far it works!
That’s interesting. I use the HDMI link from the Humax box direct to the first TV and only run through the Triax for the second one so at least I know the problem is probably not with the Humax itself. When I first had this trouble I bought another Triax but, after a couple of weeks, had the same problem. Graham suggested it might be the connections and I still plan to replace the Fs; currently it’s OK – the delights of trying to cure an intermittent fault!

When it stops working does the red led light on the magic eye stay illuminated ?
Ah, now that I haven’t checked – I’m usually distracted by the picture flashing to and from white noise with deafening effect! Will do this next time it plays up.

If the red light is on, the issue is more than likely be down to an intermittent internal fault in the eye itself or the connection from the eye to the TV. Magic Eyes are cheap enough, I would be inclined to swap it for a new one.
