    I have the same problem. I have video but no audio on the local CBS station both over the air and on cable. Toshiba says it is signal integrity and the televsion needs to be calibrated because it is slightly off the frequency. They say digital signals are very close together and sometimes difficult for the scan to pick up. Any other suggestions?

    those answers are totally, the signal is digital, and the audio information is embedded into the digital stream, so if you get a good picture, then you are getting the audio. More than likely the audio is being encoded in a way that the tv can not decode...more than likely its encoded in Dolby 7.1 and the TV only recognizes Dolby 5.1.

Model 50HM66. Why is there no sound on channels 6 & 32-1?


Could be a tuning problem but I have observed the same problem in this area, especially on channels with dubbed language translation. You can try repeating channel search to see if it helps.

I have a toshiba TV, model 52HM95. The picture is flickering and vibrant colors, especially red, look odd. It's hard to describe, but it looks similar to an infrared image.


depends what source you use. if it is a hdtv source you might have defect cables or worse/wrong connection. if you use the built in tuner for tv channels might antenna signal has problem or even connector too. check different video (picture) sources like the antenna in, video in, y/c (chroma) in etc to clarify it is not the tv itself. if this can be excluded then the tv has a problem, please let it then check by your local service.

Just got an antenna to pick up local HDTV channels. I scan the channels and none are found. does it matter if I connect to "Ant1" or "Ant2"? neither seem to work. Thanks.


According to the user's manual on page 16, press Menu and open the Setup menu. Highlight Installation and press Enter. Open the Terrestrial menu and highlight Input Configuration. Select the ANT1 or ANT2 (whichever the antenna is connected to) and select input source Antenna [not cable]. Highlight Done and press enter. Now rescan your channels. If you still get nothing, try relocating your antenna to a better place. Digital TV is highly dependent on line of site signals. So if you are in a mountainous region or surrounded by a lot of high rise buildings, you may not receive a good enough signal to register channels on your TV.

NO HDTV


There are many variables here that could cause the problem. I can receive a few local HD channels ( within about 60 miles ) on my 57H94. I am not aware of any "HD specific" settings- it's all part of the receiving circuits in the TV. The first thing I would look at is to be sure you have a secure antenna connection. Then be sure you have selected the correct antenna input on the TV (there are two). HD channels, as an example will show up as 10-1, 10-2, etc. Most TVs have different sensitivity thresholds, regardless of size. Usually digital signals, including HD, are either there or not. In most cases if a TV picks up a decent analogue signal, a digital set should receive the digital signal, including available HD channels, as well. If you are going to use an antenna, rather than cable or satellite, try to get the best antenna you can afford, that will meet your physical requirements ( indoor / outdoor,etc.). Keep in mind that not all digital TV signal are HD. All of our local stations in this area transmit a digital signal, but true HD broadcasts remain variable. I hope this has helped in some way-Good Luck!

I purchased a SANYO-DP46848 42"HDTV. I have a Cable box and my cable provider (Time Warner Cable) provides free HD Channels. However.... I CANNOT PICKUP ANY HD CHANNELS ON THE NEW TV. WHY???...


I just got the same exact one, when it searches automatically the first time it doesn't look for digital channels. go to Menu>manual channel search>cable. it will look for all possible signals and will take forever probably. the free digital channels will take several seconds to switch channel to channel, but they're there! They will show up on your screen as "DC 91-2" or similar. you can switch back to regular cable channels with the input button, you just cycle through all the inputs. hope that helps.
