My TV is approx. 2 years old and is described as LCD. My question is when all signals go to digital next February, will my TV perform in HD since we have Comcast cable connection? My other TV's have 2 different connections--coax and HD...the LCD set only has coax.
If the LCD only has coax, it will never display a HD picture quality. However, the Comcast HD Box will still display a picture using the coax connection. So, you could watch any HD channel, but the picture quality will not be high definition.

This problems,very common in LCD tv,after the tv was in used about a year or two.The new technalogy LCD tv don't handle heat very well,not like the old CRT Tube Tvs.The power supply board tend to have bad capacitors componnents leakage,that bulges up it top or puff up gases escape,that why it take times or couples pushes to the power botton to turn the tv on.U know basic electronic's,and have soldering tools and solders?Take the tv aparts,check for these bad capacitors,that bulges,puff up in the power supply board and replaced them,than ur power will work normal again.Or tries Websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
it either needs new front switch panel or new signal module, turn the tv on and disconnect the front switch board if it quits doing things on it's own you need a new front switch panel, if it still does functions on it's own you need a new signal board.
If the cable provider is sending digital signals a TV that old will not be able to receive them. If they are not digital signals they may be encrypted. You may need a cable box from the cable provider or use a DTV box to get free over-the-air digital broadcast signals.
Will you have got a lot of years on this unit. There could be a lot of things wrong here are some things to check.

I have a Magnavox TB110MW9A converter box that has worked fine for the last 8 months. Now you turn it on, the light blinks 31 times, stays on and there's nothing on the screen! The remote does nothing. (yes, I put new batteries in)
The digital tuner has nothing to do with the new signal you will be receiving in February of next year. The new video signal is a digital signal. The old video signal is analog. Your television receives the analog signal and converts it to what you see on television. You need a converter box to convert the new digital signal back to an analog signal your television can convert.
My TV remote has a slide-switch at the side to switch between the TV, DVD or VCR. I don't know if yours has one, if so, switch it to TV. It also has a button to switch between Analogue, Digital and External, so make sure if you have a button like this that it's switched to the right input.
