My MX4000 has a variable high pitched noise - eminating from the tube not the speaker system. This tends to happen when it has been on for several hours. Muting the picture (by pressing text) does not have any effect. The noise dies away shortly after switching to standby. Is this anything serious or just an annoyance?
Picture Quality is superb and is unaffected. Thanks for any advice.
David.
