Are you connected to a cable box from your cable TV service Provider and use this device to select the channel you want to view? I have an HDTV which has the QAM tuning feature. Changing channels was instant until I accepted an offer from Cablevision for a 1 year rent free box and remote combo. The tuning box is a digital & analog Scientific Atlanta Explorer 4200 HD with a card slot for your subscription specs. This bypasses the tuner in your TV and the TV functions as a monitor.

If this is similar to what you have and you don't care about the channel/current program on screen display that appears for several seconds before the channel selection completes, perhaps the cable co. can adjust your box to supress this display if it will speed up the channel selection.

There is another annoying problem with this box. If you have a fraction of a second ac power interruption which might not even cause your computer to reboot, the cable box goes into a reinitialization that could take 5 minutes or longer. In my opinion, it is not worth the $6.50 per month charge we will receive when the year is up.

We have a delay when changing channels... Why ? how can we fix it ?


That delay is from your cable service, if you are in area that is in a switch digital location that is why your are getting the delay, the cable company may need to come install an amp to fix this problem. charter Comcast and some of the other giants are still operating in switch digital but upgrading every day.

I have a new hdtv antenna and my hdtv gets all the local channels except 8. The direction from my house is 171 and that is also channel 4. I get 4 fine but not 8. what's up?


hello,
There would be weak signal reception at your antenna so it can't get the other channel. So change the antenna direction. If there's no result then increase your antennas hieght means keep your antenna at higher position.

Mitsubishi model 528256 picture and sound not in sync


Ha ha ha I see well I can confirm the television set can not delay the sound without it being none teresstial transmission .. in other words if the transmission is out of sync then his set will be and so Will 19 million others receiving the same channel so it would not be a set fault but a transmission one .

TV comes on with snow and clears up after 10-15 mins


Their is no more you can do.
You need a professional.
Stop using the TV until it is repaired.
Call the manufacturer to find you nearest authorized service center.

Slow Channel Changing


The question really is whether or not the set has always had this problem. If not, then we need to look at a possible problem with either the power supply or the tuner. Can you update this and indicate whether or not this is a new problem?

As far as using an external device (cable box or Tivo), if the tuning is done with either type of external box, then the TV would be on a fixed channel so yes, the problem woud go away.

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.
