i own a Philips 37pfl4606h/58 TV and for a quite some time now it spontaneously (like maybe once a day, but not every day) the picture freezes in some stripy pattern for a second or two (with a lot of noise), then it turns off and restarts. Firmware is the latest, the problem remains as before. I use an IP STB from my provider which is connected to tv via scart cable. I would be very thankful if maybe someone has an idea what could be the problem here.
