interference to TV

Homer Hotspur · 28-01-2011, 17:56

We have always suffered occasional interference to Digital TV . I recently bought a new LCD TV and things had seemed a bit better but, in the last week, I have found things break up when our dishwasher is on.

I have 2 questions;

1- Is this problem likely to improve when we have the DSO in April, because the power of the transmission will be boosted?
2- Does anyone know how or if you can suppress interference from something like a dishwasher? I already have ferrite clips on the aerial and RF leads to the TV itself.

Many thanks

Is it an outdoor or indoor aerial?

If the aerial comes out of a wallplate, look behind it, if the connections are not covered by a metal cover replace it by a fully screened design. Change any patch leads to ones made from sat grade coax.

It is an indoor (loft) aerial.

I have a fully screened wall plate and the connecting cables are all good quality.

The first thing to check is that it isn't mains borne, a mains surge protector/emi suppressor adaptor may or may not cure your problem it often does.

I'm thinking of getting this. Would this be sufficient if the problem is mains borne? I cannot see anything about emi suppression, but is this all part of the surge protection? I note this one also has an input for the RF connection.

It doesn't say whether it does EMI/RFI filtration or not, it may well do. This one does http://www.amazon.co.uk/Belkin-Surge.../ref=de_a_smtd
