Philips 32PFL9705K signal problems
Some channels work, some dont... but the problem only exists from time to time... most of the days it works flawlessly
I already talked to the Philips support but they say its not the TV but the Signal that contains errors... I would believe them but i dont get why the problem only appears from time to time...
I took a video to show you the problem... at first you can see the distorted channel, then a distortion free channel:
how do you receive your signals? DVB-C? Sometimes some frequency range in the cable net do not work properly. I think this is your case. You should contact a local hifi profi to check your cable signal strength (in all frequencies)...
Is your location officially covered by DVB-T broadcasts?
Because DVB-T broadcast transmission power is lower than analog one, and these phenomena can occur near the edges of the covered region.
What is you aerial installation? Is it an external one?
The tv is connected by DVB-C!!! @Toengel i think you could be right. The only thing that makes me suspicious is that the signal only is weak at some days!! Like maybe 1 or 2 times in a month.
