Humax TV problem

[Dave Plowman (News)]

I have a Humax LU23 LCD TV where the FreeView tuner died. The analogue one still worked - but of course no analogue anymore. When attempting to find stations, it would tune through the analogue band, then switch to FreeView and stop. Common problem with them, I've found, after Googling. The SCART input etc still works just fine and it has an excellent picture.

Bought a used 'motherboard' which includes the tuner from Ebay which sorted it. For all of a day. ;-(

Next time I tried it, flashing screen and nothing worked at all. So I'd guess that board had an intermittent but different fault?

Before I junk it I'm considering swapping the tuner assembly from the 'new' board to the old - that's about all i can try as everything else is surface mount. Or is the control which makes it tune etc likely to come from somewhere else? I can't find a schematic for it anywhere.

Alas, the reservations came later, after they had been forced from their ancestral lands. The White Men had no reservations about killing the Indians, though.

Unless someone has experience with this particular tuner, it's very much 'suck it and see' :( Obviously the RF tuner is just that, it doesn't care whether it's analogue or digital tv, but it's whether the DVBT decoder is integrated into the tuner, or not. I guess a clue is how many pins it has...

I know, grannys eggs and such, but have you 'scoped the PSU lines for hash?
