Technika TV aerial socket fault

[DIYspanner]

LCD19-910 model

No signal for TV in the menu. I had the TV back off and tested with a meter.

From the edge of the pcb, pin 1 has continuity to the center pin and the socket barrel has continuity to pin 8.

I've tapped the row of pins with the soldering iron in case of a dry joint but still no signal.

Any ideas for further investigation?

The Roku stick on the HDMI is fine.

Before rushing to assume hardware failure, check in the menus/settings that:

it's the correct country selected
it's digital and not analogue
it's antenna and not cable
and auto channel tuning has been done with those correct settings.

If some/all of those are not available, then factory reset the TV and set up as if it was new.

and obviously confirm that the cable being connected is really connected to something that is providing a usable signal.

Have already had an aerial cable plugged in when adding the cable to the aerial. It did work but not now.

Have tried the TV on the wall socket/cable I know works yet 'no signal'.

There is a TV reset in the Picture sub menu, just reset with the OK but not bringing the aerial feed back to life.

Its a Freeview TV.

TV reset in the Picture sub menu,

That will reset picture settings only.
You need the factory reset everything, which will put it back to how it was when new. Once that is done the first thing you should get is the country selection / tuning menu.

Apparently the reset is standby, info, menu, mute, standby pressed in that order but it hasn't worked for mine.

The DTV/USB option had disabled itself in the source menu. My Toshiba freeview TV has the TV source option but no DTV/USB option so presumed it was the same source needed on the Technika TV.

With DTV/USB enabled again, all channels are loud and clear.

From what I've read TV source is for older analogue so I'm curious why TV source is working with digital signal.

It's more to do with simplifying the input options.

Say you're someone who has a Sky box or some other set-top box. You might not have a TV aerial connected. It's a P.I.T.A. if the TV defaults to the Freeview tuner on start-up. You might have to select the correct HDMI input each time. HDMI CEC can take care of that but it's not always reliable. Humax PVRs screw it up, and Apple TV streamers can mess up the way it works, too.

Pruning the input options can make the TV either behave more predictably, or at least avoid the "Is it HDMI 1, HDIM 2, HDMI 3.... and what the hell is AV?...Why can't it be simple!?!" gripes of family members who just want to "watch bloody Corry".

I have customers who still have VHS(!). Modern flatscreen TVs don't do well with that as an AV input. Some newer TVs don't even have an AV input. AV-to-HDMI adapters don't work because the sync signal from tape is too jittery for a good picture lock. Analogue RF is the last remaining option, and it's just as good for picture as AV. Disabling the Freeview tuner but leaving the analogue in with a couple of channels tuned for the VCR (0 and 1 normally) tends to work. So, the point here is that everyone's mileage is different.
