I've had a Comwell digital sat receiver set up in UK for receiving Astra-1 at 19.2E using 80cm dish with twin LNB. This was a Dutch receiver with in-built Seca slot because I bought it to receive Dutch channels through Canal+. Everything fine for 2 months but since about two weeks ago, we've lost all Dutch channels: no signal. However we can still get many other channels eg German, Spanish, French on both H and V polarisation. We are however not getting any signal on several H transponders inc the Dutch.
We thought it was a dish alignment problem but the sat engineer we used said not and it has proved to be a fault with the signal input on the receiver - he suggested that we were using too small a coax and that the F input connector was warming up and losing contact with the coax core.
Is this likely? Or is the F socket on the back of the receiver likely to be broken or faulty. Do we need a new receiver? I've tried with a short length of thicker coax (CT100) as a bridge but that hasn't been any better. We've even had receiver checked out and loose joints in the tuner resoldered - no effect.
Any suggestions where to go from here?
Thanks
