Confirmation of a presumed Amstrad box tuner component fault

[Tembo11]

At various different times and with various different groups of SKY channels I will get a group of succesive channels to give the eror messages "No signal being received" or "there is a fault with this channel" yet if I continue up the listing using the remote till I get a clear picure and then come back down the list, those same channels that were faulty just seconds before now seem to work correctly.

I'm presuming this is the tuner section on it's way out rather than the LNB?

Either the tuner or possibly the capacitors in the power supply unit.

If its a really old Amstrad the best thing you can do it take it outside and drown it in a bucket of water!
