Hi Pikpilot,
So let me get this right take the fittings off both ends, put the copper center and brade together at one end and then put a multi meter over the center copper and brade at the other end. What should the multi be set to and what reading should i get?
Is this correct?
Thanks again for all the help
Rob

Rob, don't take the connectors off as we are looking for a poor connection in the connector.
If you have taken the connectors off the when you put them back do this;
1) put a small kink in the central wire to ensure it is making contact inside the pin
2) after putting it back together, connect your multimeter on the ohms range between the inner and outer of the connector. It should read Infinity.
3) do the test in my previous post but using the multimeter instead of a battery and torch bulb. Reading should be around zero ohms

Hi all again,
now i am still hoping to cure this and get back to using my Sony tv as the alba has a good picture but the remote and slow reaction time is driving me nuts. Now if all else fails i may need to call on a professional, does anyone have any impartial advice for a good Ariel tech in the Oxfordshire region that's not going to cost me the earth.
By the way alba says 100% signal 9 % quality on most channels tonight, what's in my system that's causing the low quality? If it is, not sure i believe these signal meters now they all seem different on each set or box.
again thanks all for your help and patience with me.
regards
Rob.

rob: Although pikpilot has described a way of testing your cable runs using the minimum of technical measuring equipment ,i.e: an ohmmeter, if you do not possess such a device then I would suggest that you go into your Sony's tuning menu and select "manual tune" followed by entering C60 into the box but NOT being followed by pressing search or scan, because if any signal is being received on C60 then no matter how low it might be it should still be indicated on the strength / quality bars, the TV being allowed to remain on this mode whilst you move cables around and walk across the floor above the area where the cable is located whilst observing for any slight changes that might take place in the S & Q indications, because should any be seen then this would suggest a faulty connection somewhere in the coax run.
The point about this type of test being, that by entering a channel number into the manual tuning box but without pressing scan effectively makes the tuner act like a signal meter devoid of cut off threshold levels, this then enabling very low levels of signals to be viewed which would otherwise have been bypassed if search was pressed.
By the way, some Sony devices might not allow you to carry out the aforementioned test, and so you should initially try the test out using Oxfords BBC on mux channel 53 just to verify if it works. (also try C59)

Thanks again jb 38, i am sure that it does not do that on my Sony bravia, if i do the manual tune it just asks for the number, i put it but there is no quality or strength on the manual tune or the auto. I can only see the meter after when i go into the info section and i only get strength there no quality. I will try again later.

Dear all,
update is i think that one of my issues is a weak signal due to the number of splitters in my system. I have put the fly lead that i made back on from the tv point to my dvd recorder, now last time i did a scan with this with the first set up ( no fly lead and cable split under the floor to two points) i got 9 channels ( Sony tv signal said high however and all channels found).
scanned with flylead to dvd player now have all the channels and i can check the signal and quality on the Sony dvd recorder unlike the Sony tv where i can only see the signal strength. Strength is now between 68 and 89 and the quality is 100. So there must be an issue with the cable or the number of splitters. However the blocky picture on channel 60 programmes is still present, not as bad but still there so i have put the alba set top box back on which does not.
I think that my Sony equipment must be more sensitive to some form of interference than the alba, hopefully when the 4g splitter comes it may cure the issue and boost the signal enough to use the under floor cables.
regards
Rob

Are your splitters of the passive type (do not require any power) or of the active type needing a power supply?
Reason I ask is that passive splitters rely upon having all the outputs connected all the time to maintain correct impedance matching throughout the system. If you unplug just one output from a passive splitter it will seriously disturb the signal distribution to the extent that the signal delivered to a connected input will be seriously reduced perhaps by as must as making a quarter or less of what it should be! (The mathematics is complex, but it is essential that correct impedance matching is maintained throughout the system, so every input is matched to its supply at 75 ohms.)
An active (powered) splitter, on the other hand, has buffer amplifiers built in so each output is 'independent' of all the others so impedance matching is always maintained no matter how many outputs are connected.

Forgot to add that a signal strength of 100% is not good! You can have too much of a good thing and 100% is too much. Typically you look for around 70-80% maximum.

Powered splitter on the way, have passive splitters one splitter has 4 output i only use 2. And then split again downstairs only a two way.

Update, power splitter 4G ready now in loft with extension lead running up there for testing. Thought it had cured it then started blipping again. The signal strength is much improved however with the split under the flooring i still have in place. Run the fly lead above ground straight to the Sony bravia tv and that still did not stop the glitching. So tried the Sony dvd hhd on the fly lead above ground and again after a bit it has started to glitch also, also done with under floor cable and also glitching again. It is as if both Sony and hhd are ok until they have been on for 5 mins then it starts again.
Alba set top box is fine with no glitches well maybe one in 2 days for a second. So confused over this, i have the filter in place signal good quality good only glitching on channel 60, alba box works fine grrrrrrrrrrr, will use that for now but have to give back as borrowed, so lets hope the replacement i buy has the same shielding. Now think it must be next door, but they cannot change there setup apparently.
any other ideas or advice would be appreciated.
regards
Rob
