Philips 28PW6324 intermittent yellow color on foreground

[VirusCrazy]

Hi,

I recently bought a Philips 28PW6324 tv which was faulty. At first, sometime, a yellow "foreground" came slowly over the screen and then disappears slowly. After, the screen stopped working, just black. Now, i've opened it and clean everything but there is stille the problem of the yellow color which comes and goes slowly. It's like if there were a sinus signal on a yellow color (i don't know where because the tv uses RGB colors...).

Where can it come from ?
