Strange dvb-t signal drop
TV: 46PFL6606T
When I connect my sat tuners hdmi to the tv, the signal drops on the internal dvb-t from 100% to 30%. I find this a bit strange. Why would that happen?

Hello, some Philips TV model cannot perform the fw update directly from the net anymore.
Please check in the Philips support page in internet if a newer fw is available for your TV model and downlaod it.
If yes, save and extract it in a usb key. Install it and let us know.

Updated, no change. DVB-t signal drops way down when I turn on my sat receiver which is connected to the tv with hdmi.

If the sat receiver is turned off (but still plugged to the HDMI input), does the DVB-T signal return to normal status?
Can you try disconecting the sat aerial from the sat receiver, and turn it on?
Does the DVB-T signal remain at 100%, if the sat aerial is disconnected?
If yes, maybe you DVB-T aerial uses the same cable as your sat LNB, and there is a problem in the installation?
(When you open a sat receiver, it sends some DC voltage to its aerial, to power the LNB).

Signal returns to normal when there is no signal on the sat tuner hdmi (standby or switched off).
It turns out anything connected to the tv makes the dvb-t signal drop. I connected an apple tv via hdmi. Same thing. When I connect it and turn it on, the dvb-t signal goes to crap. Another member of the household said the same thing happend when a speaker connected to the headphone output on the tv was turned on too.

Looks like the problem had to do with a faulty signal amplifier on the antenna. Fixing it got rid of the problem. Still strange that anything connected to any input on the tv triggered the signal drop.
