My 50WT29 has a problem whereby it has an intermittent fault. This fault, when happening, manifests as no picture or sound but you can access the menu, after a delayed period, and that appears as 3 badly mis-converged and curved menus. If the set is turned off and on again it sometimes recovers and shows a picture and sound just fine. Then, sometimes, when a channel is changed or the AV source is changed, it just stays on the previous source. Now I am told that this is software/data fault whereby the processor is not reading the data table due to a faulty "something". And its this "something" that I need to indentify. Can anyone help please ? Someone has said that it might be the EPG module but I dont know where this is situated. Can anyone point me in the right direction ? Thanks in advance.
