Hello All!

I have a Comcast DVR / TV issue that started AFTER installing and operating a wireless network adapter in a nearby personal computer.

The issue is that the live TV is BLANK (no TV picture or sound) when first turning on Comcast Motorola Dual-tuner DVR (DCT6412) and TV. The only way to get the live tv on is to select 'My DVR', after which the TV picture and sound for live TV come on just fine.

If the PC with the wireless card is off, the DVR and TV come on and work fine (in other words, I select 'all on' on the remote and the DVR box and TV come on fine, usually on channel 8).

The 'blank' screen issue only occurs when the personal PC with wireless card is on. Note: PC is in another part of the house, unrelated or unconnected to the TV or DVR.

Has anyone heard about this issue or know a solution?

I appreciate any tips - Thanks!

Are both of your wireless systems using the same wireless channel?
The problem is probably that you do not really turn on the PVR you "push" its power button which will turne it on if it is off and will turn it off it is on. It appears that when you turned on the PC it also so when you thought you were turning the TV on you were actually turning if off.
