If this is a Freeview receiver/recorder then it could be too much signal thanks to the Freeview retunes going on. Your aerial is more sensitive at some frequencies, so there's more signal power higher up the frequency range.

A simple and inexpensive diagnosis tool is a variable attenuator. The MA1620 on this page is perfect for that job:
Splitters amplified splitters and attenuators

It will give you a way to reduce the signal level at one TV without affecting the other TVs in the house.

How do I connect my DMR-EH57 to freeview


Connect a suitable aerial via a coaxial/RF lead to the 'RF in' socket. Connect another coaxial/RF lead from 'RF out' to your TV, and/or SCART or HDMI leads.

Access the 'setup' option within the menus to tune in to Freeview broadcasts.

Hi I have two freeview boxes running from one aerial which split at a boooster box, one tv works fine, it the farthest away from the booster box, but the other has some channels freezing up and stuttering,...


Hi,

The problem you describe is called "Digital Cliff Edge" and it's caused by signal loss. I wont go into the specifics of that at the moment as it's not going to help solve your problem. I you want more information about DCE, try an internet search.

As you are using the same aerial and booster/splitter for both TVs, you are correct in ruling these out as the cause of the problem. The fault is probably in the co-ax cables or connections but you might have a faulty freeview box. Please run through the following checks to establish the source of the fault.

1. Swap your Freeview Boxes - you shouldn't need to re-scan/tune as they are running off the same aerial..
If the Freeview box from the TV that is working correctly freezes and stutters on the other TV, the fault is probably in the cables or cable connections. Next, try the "faulty" Freeview box on the TV that is working correctly. If you get stuttering sound and freezing/pixellation you probably have a faulty Freeview box. DO NOT SWAP ANY CABLES FOR THIS TEST.

If the problem is the same after swapping the freeview boxes:

2. Swap any non-fixed cables, e.g the co-axial "fly-leads" and scart cables - one at a time. See if the fault "moves" with the swapped cables. "Fly leads" are the short co-ax cables that link the Freeview box to the TV or the TV to a wall mounted aerial socket. If the fault "moves" with the swapped cable, you have identified the source of the fault and should either repair or replace this cable.

Try these tests first and post back with the results. If you haven't identified the source of the fault, I will try to assist you further.

Regards,
BElectric

Nintendo 64 - sound not working on new TV


Because the 64 is somewhat old I would suggest getting an aerial splitter because the system may not be able to function properly with out it. Try it and see how it turns out. Or, if you don't mind, you could play that game on the computer if you have one. Download Project64 from:

Similar problem as you helped me solve before.


OK, I think I see the problem there.
The aerial lead from the DVDR to TV should be removed.
You should have it setup the same as the other Freeview - VCR - TV
Nutshell time:
Main aerial to Freeview input.
Loop aerial from freeview output to DVDR areial input (all this does is allow you to watch freeview, or standard both out of the DVDR)
So..
Scart from Freeview to DVDR input
Scart from DVDR output to TV
Set DVDR to AV input mode.
Set TV to AV (whatever number you need for that..you now won't get anything on screen unless you have the right input selected)

If you can now see the Freeview picture on the TV and change the channels with the Freeview remote then you should be set for recording.

Having the aerial and a scart lead both going to the TV is not needed.
