it takes about twenty mins of button pressing to get the tv out of standby....the screen is nearly all red in colour with a band of green at the bottom part of screen...but today when i switched on i got a different effect as shown in photo...i then switched off and then back on and the picture went back to red/green original fault the over all picture looks like a crt with one of the colours missing...i would be grateful if any one could advise me on these faults.
