Hi Mike

Have done as you suggested. I have two indicators for each channel; and Strength. Quality is a big fat zero for every channel bar one, which registers a measly 10%. On strength, most are at or around 20%-30% with two at 50%. There's nothing beyond 50%.

What now?!

Thanks
Nick

Nick:

Your signals are far too low for reliable , which is a surprise as you are only 15 km from the . You should aim to have signal strengths between 65% and 85% and no more. So start by checking that all the signal connections are good and that all the plugs are fitted correctly and that none are lose in their sockets. If you are unsure about any lead and/or its connection it is best to replace them as they are inexpensive. Also check to ensure that any or distribution system is working correctly - don't just assume that because a red '' light is lit that all is well as it may not be. One further check is to ensure that any HDMI is well away from the aerial cables, HDMI data signals can disrupt RF signals in the aerial cables.

Hi Mike

I've been through your checklist and nothing seems wrong. Everything plugged in correctly and nothing loose. Am I at the stage where I've got to get an expert in to check it over or is there anything more I can do? As I mentioned, all other are fine; it's just the HD channels that are missing.

Hi

I am having a problem with a Sagemcom box that appears to have started around last Monday.

All are ok via the TV are fine, which is strange because of course the aerial loops through the Sagemcom box. However, the majority of channels are distorted when viewed via the box and it appears to be the ' ' that is poor.

I have already performed factory reset on the box and also the reset procedures.

Graham Hill:

If the on the TV is fine then that suggests the system and cabling are fine. However, it does suggest that the box has a potential fault. Try disconnecting it completely from the signal and supply for at least five minutes. then reconnect and allow the box to reset itself, usually another 5 minutes is sufficient. Then check whether reception has returned to normal. If it has then your fine until a further reset becomes necessary. If it happens again that suggests that the box it developing a fault.

Hi All .

I am getting my from the through a Humax box and a plugged to the . When i check the strength for HD it says 47% - 50% but with the booster unplugged its around 26% - 29%. The signal always says 100%. Do I need a bigger to get my signal strength above the 50% mark or is this the norm. Can anyone advise on this predicament please. My post code is SN3 2PZ ( Swindon,Wilts ).
Cheers guys.

Ade Langford.

Ade Langford: Do you actually have a problem with breaking up? Which HD are you referring to, as different channels are broadcast at different power levels?

break up is intermittent and across
all HD and some SD. I have also had a 4g filter
fitted which works to a degree. I just wanted to
know if I could increase the strength to
over 50%.
