Do I have to channel scan every time I turn my TV on?

[ROBINKA]

I have an HD Digital TV. I have an antenna hooked up. I have been having to channel scan everytime I turn my TV on. Is this normal or is there a way not to have to scan each time? Thanks.

:welcome: ROBINKA,

I haven't heard of any sets requiring a new scan every time it is turned on. Please tell us the make and model number of your set and perhaps someone on the Forum can specifically address this problem.

perhaps your television is getting broken or deffective, is not normal that gets reseted itself each time you turn on the unit, have to consider that converter boxes and digital televisions have a microprocessor and ram memory too, are like small microcomputers the extreme heat can cause overheating in the system and possible damage to the delicate components.


best regards

Check the manual under the "troubleshooting" section, this sounds like either a defect or some type of error where the TV thinks it is being powered up for the first time ever--every time.

 

[ksnetv]

Another thought--have you unplugged the TV, waited about a minute or two, then plugged it back in to see if the problem still exists?

Is your TV always plugged in even when it's off? There may be a few TVs that lose settings when not connected to AC power for a while.

Most tv sets I've seen lose their settings when unplugged. I don't understand this, since a small amount of flash memory would retain all your settings when unplugged.

It made sense when the TV needed to be plugged in to pre heat the CRT for "instant on". I can think of no good reason why TV sets should consume ANY power when switched off now, with plasma / lcd / led sets needing no power for "instant on".

Maybe could the Television be in the Store settings or demonstration mode , where just start to show some flags or facts about the television model, and each time you turn on the tv ask again Home use or Store demonstration, my television can be set for demonstration or home use.

Flash memory costs $$ and has a limited lifespan for writes. Companies like Apple are gobbling up a lot of flash memory too.

Power is needed so you can turn it on with your remote. Power consumption is less than 1 watt for many TVs when in standby anyway and the new Energy star requirements are pretty strict.

Thanks for the info Francisco.

 

[ROBINKA]

My TV is always plugged in. It's mounted on the wall. The light in front turns blue when it is on and red when it is off. Thanks for the suggestion though...

 

[ROBINKA]

I have not tried this yet but I will. Thanks

 

[n2rj]

Well it's definitely leaning towards "your TV is defective." Hope it's still under warranty.

I bought a Cobra converter box but can only scan channels 1-69, is it possible to get more channels with another box?

No, in fact, your box won't get channels 51-69 anymore, because the government auctioned off those channels to wireless companies. There are still a few channels using 51-69, and some channels will show up there as "virtual" channels. But there are really less than 50 channels available for TV.

And now the government wants to auction off channels 32-51 for cell phones and internet, too.

BTW, what is this "COBRA" converter box? I've never heard of it before.

 

[springhillgirl]

Sorry, it is a Coby! Ok, so the chances that I will ever get Bravo or the Food Network are 2? Slim and None? Guess my downsizing to save money is not working out very well for me!

 

[MrPogi]

No Food Network or Bravo - although you can get some of what you want on the internet. Try HULU.com, Netflix, or go to the network's website.

PBS and it's subchannels have good programs similar to Food Network (PBS Create and Learn) and some Bravos shows are available from Hulu Hulu - Bravo and Netflix.

no happen that DTV uses the bands VHF1 CHANNELS 2-7 vhf2 7-13 and UHF 14-69, the worldwide DTV systems uses those bands so the boxes, televisions will not tune more than the channel 69 as highest, that is why the TV stations can use subchannels in the same frequency.

My guess would be that you have weak signal from your antenna, and that improving your antenna or antenna placement will fix the problem.

If you tell us what antenna you have, post the URL for your TV Fool radar plot, and tell us what channels you are having problems with, we may be able to help you.
