Hey,

I've been having weird discolourations on my TV, I have a 42PFL8404H/12. And the problem occurs after about 10-30minutes. I have an HTPC (AMD Fusion E-350M1 based) with XBMC (Ubuntu 11) connected to my TV and I have tried several different HDMI ports and HDMI cables, yet the problem remains.

Does anyone know what this is and/or how to fix it?

Thanks in advance!
