Sharp LC32SH130K Humming Sound


Standard Member
Just bought Sharp LC32SH130K, delivered this morning.

When turned on has a constant irritating buzz, from looking around a common cause seems to be a problem caused my the power going to the lcd 'lights'.

The solution's given were all to adjust the brightness/backlight, I've done this to no avail.

Any help would be appreciated.

It was bought via an ebay seller so if I can fix it without the hassle of a return that would be useful.

Buzzing can be caused by the transformers on the invertor board and is not really repairable without replacing it.

I suspect you have no option but to return it.
