probably water in the downlead to the loft. I remember having a labgear
distribution amp and it looked a bit discoloured on the pcb near the diodes
and transformer, but it was a really good unit. It only needed a capacitor
to make it work correctly. Trouble is the modern stuff uses el cheapo bits.

I have a Vision V52-100 amplifier (14db - 26db UHF, 0db - 16db VHF + FM)
in my loft and over the past few weeks I have had issues with my TV
signal for certain channels. After further investigation I have taken
the top off the internal amplifier and noticed some blackened areas
around some components. When I connect the aerial cable direct to the TV
I am still not getting a good signal, so I am assuming that I need some
sort of amplifier. I have checked the Vision website and they no longer
list it. Can anyone help with what would be a suitable replacement for
this amp?

Look at www.blake-uk.com (who are in Sheffield) or
www.fringeelectronics.co.uk who are at Clipstone near Mansfield. They both
make good and reliable products, the former under the ProCeption brand
which you can also buy from Toolstation.

The fact that you say you are not getting a good signal without the amp
suggests some other fault which may or may not be signal level related. It
would be useful to know roughly where you are located, the type of aerial
in use, the location of your current amp (is it masthead/in the
loft/setback?), how long the cable run is to the amp and from the amp to
TV, and finally which transmitter(s) you are using.

Two useful sites you can look at:-
www.wolfbane.com will, from your postcode or map ref, tell you which
transmitters are available at your location and the approx signal
strength. The last column about aerial type can be ignored - it is
notoriously pessimistic.
www.macfh.co.uk, click on index, and then select the line about
terrestrial TV aerial alignment in section 2. It is straightforward to use
but it has the advantage over any other site of this type that it shows
you the signal path on Google Maps, on an OS map, and it shows the signal
path profile. You can enlarge the Google map, then go to satellite view
and move the lollipop to the exact position of your aerial.
