No Picture LG RZ26LZ50 please help

[read1976]

Hi,
I purchased a LG RZ26LZ50 TV some 2 years ago that I have been quite happy with until just the other day. The TV seems to lose picture but you can still hear sound.
The problem happens no matter what source I use. If you power down the TV and then back on then the picture comes back on for a few minutes.

When there s a picture there is absolutely nothing wrong with it.

Can anyone offer any advice please?

Thanks
