How do I tell my 53FDX20B to recognize digital instead of analog?

there is no make of tv brand, model,year you purchased it?
in australia we no longer broadcast analog only in digital now.. so if your tv does not tune in to any station/channel its analog.. you can still use it if you connect a set top box or a device which has a digital tuner. set top boxes are around $30 , even a second hand one would be ok or a free one from gumtree online classified

Digital audio will only be enabled through the optical in jack. And the sourse has to be a digital broadcast.

Hi

A little more information about the make and model of your amplifier would make it much easier to tell you exactly what button where to press on your amplifier.

But I am sure I can point you in the right direction.

Analog only means that although you have connected your DVD player or Settop box to your amplifier on the digital coaxial input you have not yet setup all that needs to be setup.

Start by checking that you have enabled the digital coaxial output on you DVD player. You can set the following if it is available:
1: Select your Digital output to ON
2: Dolby Digital setting must be Dolby digital
3: MPEG switched to MPEG, not PCM
4: Select 96Khz/24bit or higher data transfer on coaxial cable.
Note - all these setting might not be available depending on the manufacturer.

Now you will already know the input switching on the amplifier - so select DVD.

Now to activate the coaxial port you must look for a button named "input mode" either on the amplifier itself or on the remote.

Press this until the amplifier says Digital.

Now get ready for great sound.

Hope this helps!

You've not given us the manufacturer, make and model number, but I see 3 analog inputs on the left and the usb on the right. This tells me the analog audio and video signals must come from a dvd or vcr or tv-tuner. You say getting channels, so I'm assuming you've not hooked up to a digital ready tv hooked to cable or dish or digital converter. THERE ARE NO MORE ANALOG SIGNAL CHANNELS ANYMORE. Everything went digital in June 2009. So there you have it. If you don't have usable information going in, you can't get it out. try it with sterio audio and video from a digital tv that is receiving channels, and I think you'd then see sterio and video out of your pc.

well you are gonna need converter okay its not digital sorry for the bad news good luch shad

if the tv is less than two yrs old than yes.

Sanyo's customer service responded that this TV is not digital. If it's connected to an antenna, you will need to purchase a Digital to Analog converter box.

No it is not HD ready, your set has a NTSC tuner the new digital sets have an ATSC tuner, BMW Rider

First thing to check, would be that there is no oily liquid or residue around or on the printed circuit boards underneath where the picture tubes are. If there is, one or more of the tubes are leaking out the coolant and the seals will need to be repaired as well as the board, if it is not beyond repair. If that does not work, check out the power supply voltage . Check to see if the horizontal output transistor is shorted, or that the convergence Ic's are not causing the set not to start up. Good Luck
