I have just had my LG TV BACK FROM KNOWHOW FIFTH

Resolved Question:

Hi I have just had my LG TV BACK FROM KNOWHOW FOR THE FIFTH TIME! Originally the main board ? was faulty, so they replaced it free of charge. but since then the TV does not give out any picture or sound through HDMI 1,2 OR 3 outputs. I have changed the cables . phoned sky the did checks on the sky box ,they then asked me to fit a scart lead. low & behold, there was picture & sound on AV but that means still no picture & sound on my blue ray DVD. Knowhow insist that there is nothing wrong with the TV.

Above is the only user level option to resolve HDMI input problem and if it doesn't help then I'm afraid it is definitely hardware related issue and main board of TV will need to be replaced, sorry for this news.
I trust my input will help you out. Please feel free to respond if you have any additional questions.
