Sharp Aquos LCD LC40LE600E High pitch noise


Standard Member
Hi everyone

Sorry I'm new to this so don't really know much technical stuff.

I have a Sharp Aquos LCD LC40LE600E that I've owned for around 18 months that has just started to randomly make a high pitch sound for a few seconds and then go away. It is getting more frequent and I just don't know what it is.

If anybody can help me it would be much appreciated.

Thanks Catherine
