[QUOTE="Grmblwd, post: 1150525, member: 418813"] Hello, I have 2 satellite dishes one at each end of the house (35m between them) One has a Sky dish and the other is a 60cm dish, both have a Humax Foxsat-HDR television recorder, both upgraded to 1TB HDD, and both have a 4 way LNB's with only 2 of the 4 being connected. I have been having a problem with the Sky installation where the picture is messing about occasionally. I get some pixilation, scribble, ghosting etc. It started about 2 months ago, and I assumed it was a neighbour's tree causing the problem and he kindly chopped 10ft from the top, clearing the line of sight. The problem still occurred so I checked the LNB and found the front cover had broken (been in service since 2007) So I replaced the LNB and re-made the connections on both ends of the Co-axials, (there are 2 connections) and it is still happening. I swapped over the Humax boxes, but the problem still persisted, so I assumed the Humax boxes were OK. The other 60cm installation has no line of sight problems but is now playing up and appears that both installations have faults at the same time. I replayed a recording made of the same programme on both the boxes, and they each had faulty pictures at the same place in the recording, but were not the same level of fault. I have had no problem at all since I installed the systems in 2007 and both had 95% Signal strength and 90% Signal quality. This now sems to fluctuate where both LNB1 and LNB2 signal goes off and comes back on again, and the levels fluctuate. I would guess it happens maybe for a second or two and very sporadic on the time interval. I cleaned both dishes, checked the alignment and both are good. I know weather has a part to play with rain causing disruptions, but in the past the rain had to be torrential to cause a problem. I have some technical knowledge, but do not consider myself an expert. Thanks for reading this missive. Any Ideas of what may be the cause? Regards [/QUOTE]
