Need to know if my tv is digital or analog?

The set is trying to auto program the available channels and it can't find any because since the change from analog to digital [FEB 2009] broadcasting requires a "converter box" to translate the digital signal back to analog. Check around and see if you can find a converter box. They were available for $20 with a coupon, maybe they still are. Try an electronics shop or dealer for that info.

You need a Digital to Analog converter box as your TV is analog, and all broadcasts, since Last June 12 are Digital.

During a recent move the remote was lost. I have the 6420FF in my son's room and trying to set up dvd and wi console set up, but cannot adjust tv via menu button on tv. Is there any way to set-up game system and/or dvd without remote?

Yes you will so don't ask what you already know.

I'm sorry, but a DWT2405 is not digital. You will need a converter box.

I didn't see anything on the internet about the features.

Does your tv tuner have the capability of tuning into channels with a decimal point in them, then it should work. If your tv doesn't have that feature, chances are you will need a converter box, cable tv, or satellite.

if you do not have cable, fios or directv you will need the converter box

No this set isn't. I think you'll need a converter box. This is classed as an analog TV.

Yes, you will need the converter box in order to view the digital channels if you are receiving off the air signals but if you have cable or satellite TV, you might not needed. You can click here to know the specs of your TV, it has an analog tuner and not a digital.

From the side of the carton in which it came:
CONSUMER ALERT: This television receiver has only an analog broadcast tuner and will require a converter box after February 17, 2009 to receive over-the-air broadcasts with an antenna because of the U.S.'s transition to digital broadcasting. Analog-only TVs should continue to work as before with cable and satellite TV services, gaming consoles, VCRs, DVD players, and similar products. For more information, call the Federal Communications Commission at 1-888-225-5322 (TTY: 1-888-835-5322), or visit the commission’s digital-television Web site at: www.dtv.gov.
The only other thing I could add to this, is that the Post Office in 2009 will get the task of handing out $40.00 coupons to to anyone wishing to purchase a converter.
