why does my plasma tv screen occasionally blank


I have a Samsung PN42A450 connected via hdmi to pioneer elite vsx 92 txh receiver. my time warner hd cable box is also connected to the receiver via hdmi.
My problem is every few weeks on some occasions the tv screen goes completly blank and black for a second or two without any sound and then comes back to normal. this keeps repeating sometimes every few minutes.Please advice
thank you.

WOW , talk about timing !!!

I am having the same problem with my Samsung plasma tv , model #HP-R4252X , and Brighthouse cable service .

The tv will go blank , as if you turned it off . Sometimes for just a few seconds and sometimes as long as a minute or two . When it comes back sometimes it is clear and sometimes it will have digital artifacts either in the video or audio or both .
This will not only happen on just the plasma tv but will also happen , at the same time , on our other tv which is analog and tuned to a different channel .

I am currently playing the fixit game with Brighthouse , on my equipment , to no avail ! So far they have made the following changes , repairs and checks :
1.) Three new HD box's for the plasma and one new digital box for the analog tv (digital for the music in my 2 channel room). Actually two of the HD box's were rebuilts and the last one is brand new .
2.) New ends and patch cords from the wall to the cable box's.
3.)A new (thicker...they have two types of cable the thicker one is capable of carying more info and is shielded) cable from the terminal/junction box to the box mounted on my house .
4.)A new box mounted on the side of my house .
5.)A check of all of my inside cable runs and replacement of the ones found to be noisy .
6.)Splitter changed twice .
7.)New connections made in the new box on the side of my house .
8.)A check of the new line from the terminal/junction box to the new box on the side of my house .
9.)Three modem changes . Yes I am having problems with my internet going down intermittenly like the tv and my phone service too !

The status now is twofold . First they found "noise" in the line supplying the junction/terminal box and they have requested a check of that line . They never followed through . A second request was made and is still pending after a week . You have to call to find out the results and make sure that they will do it !
They are coming out Monday to check all of my inhouse telephone lines .

These 'visits' have been going on for a couple of months now and I have not had any positive results . As a matter of fact the tv problem is what started it and it has now progressed to the internet and telephone service . It is getting worse not better !

Most of the problems happen during the daytime Monday through Friday . This is the time of high bandwidth demand from their commercial customers .
And all of this through an aging infrastructure originally designed for regular tv signal transmission only !
I am sure that they have upgraded and renewed the equipment in their receiving stations and transmission terminals . I know that they have not upgraded or renewed the aging , rusty and leaning junction/terminal box's in my neighborhood within the 20+ years that I have lived here . And they have not replaced or renewed the line feeding these box's in at least 10 years !

I wonder just how bad can Verizon be ?

Sorry for the rant .

Good luck .
I am not using an HDMI cable but still experience the problem .
It will not happen every day . It just went 3 days without an instance at all . Today it happened twice !

I have to give credit to the Brighthouse crew , they are tenacious and dedicated !
