Default Toppy: Intermittent picture breakup and 'Signal lost on tuner1'?

Hi all,

A while ago I started suffering highly untypical randomness on my
trusty Topfield PVR 5800 STB. Replacing most of the caps in the PSU
seemed to fix it. ;-)

Now (a few months later) it's started suffering random audio cutouts
along with sporadic picture breakup and eventually (maybe 5-10 mins),
a total loss of picture / signal. If you try to re-tune it you get
nothing.

Turn it off, wait awhile (1/2 hour) turn it back on and (you can then
retune it) it starts off fine then after another 30 mins the audio /
video starts breaking up.


I'd recommend that you post the same question in the Toppy UK forums
http://forum.toppy.org.uk/forum/

Heat related fault?
The 5800 can run hot and it doesn't have a fan (unless you have fitted
one yourself). Have you changed the stacking of you 5800 recently? Is
it now in a stack of other equipment that runs hot? The 5800 needs a
free flow of (cool) air. Turning the box off for 30 minutes would let it
cool down.

Is it one or both tuners giving problems? Is the problem on all TV
channels? The Signal Monitor TAP and the equivalent in the Topmanager
program for the PC can give you near real time information on the signal
levels, quality on all MUXs and both tuners on the same screen. If you
are not getting close to 100% quality on all MUXs then you will have
problems. Signal levels of 60%+ on a Toppy are OK.

How have you got you 5800 connected to the aerial? Via a single cable
to one tuner and then a short cable to the other? Via two independent
cables, perhaps by way of a multi output amp/booster?
