There isn't really any such thing, these days. You take a flatscreen TV, and
you do what you can with it, based on experience. A lot of the time, its a
case of going down the manufacturers' preferred route, of board swapping.
That said, power supplies and backlight inverters are often repairable. So
what's the problem ? Good possibility that someone on here might know the
answer, or be able to point you in the right direction. If you never
actually ask the question, you'll never actually know ...

It was working fine, then didn't work? This suggests a possible change in
reception conditions. You should definitely swap the sets, as suggested.

However...

You've lost SD reception (SD being 625-line PAL), but not HD, right? As far
as I know, SD and HD use separate tuners. (I think.) I could be that the SD
tuner has gone out.

** The RF stages do not change with SD and HD.

Do you mean just the front end, or the IF section, too?

Given his description, it's hard to believe it was caused only by a change
in signal level.

We'll have a better when he swaps the sets.
