Question about Toshiba 42H81 42" Rear Projection Television
I have been going back and forth with Comcast and reception issues. We had no problems at first when we upgraded from Basic Plus to Digital Service and installed the cablecard. About 2 weeks later, some of the HD channels would get "Weak or Scrambled Signal", and soon others would have a picture but "tiling" or pixelation. It eventually gets so bad, that it effects the analog channels as well, and I wind up with a green screen. After a number of different things (rebooting the tv by unplugging and replugging), Comcast trying to boost signal, we get a nice clean picture on all channels, so it looks like the problem is solved. But, eventually (anywhere from 2 weeks later to as soon as the next day) we starting having reception problems again. Comcast sent out techs yesterday. They checked the signal strength, and wound up changing some things out both inside and outside the house, including replacing some wiring that was coroded. After doing all that, it did not solve the problem. So, later on they came back and tried getting rid of the cablecard and going with the converter box. That did not work either. They determined it was not them, but my TV since they showed me that they could plug this old 13" tv into my cable system and the Analog channels were coming through fine. Here is where it get weird. We left the tv on when we went out, and came home a few hours later. Tiling was gone on the staion that we left it on (Local HD channel) and when he starting to look at other stations, our analog stations had come back, no green screen whatsoever. I don't know if the problem is solved, or if it is just temporary again. Anyway, the TV is a Samsung HL-R4667W, bought in 12/05 and is used mainly in the evenings (so low hours). DVD, XBox, and VCR never had an issue, and prior to going to Comcast Digital (just using Comcast Basic Plus Service), no issues with broadcast or Cable TV (no tiling/pixelation or green screens).
