Is our Quasar TV (SP2723) a digital or analog television?

no model TV told at all.nor year made. 1967 to 2004??????
not sure what you are attempting at all
first off there are no more VHF/UHF wide band TV now.
its all gone. bye bye. HDTV yes , old analog is gone. buried.
this TV is NOT CABLE ready, back in 1967 era,no such thing.
make relic TV work needs
a video to vhf channel 3/4 converter like old Pong or ATARI games had.
yes there are converters. to do video to modulated channel 3/4
but not told at all what is your video choices,?sources.
DVD
RCA video jacks.
cable modems do not have those.

I bet you have cable modem or a SAT modem
and converting HDTV to analog is wow hard. if not impossible
one can record a video sources and convert it using PONG adapter. to old CRT motorola quasar.

quasar Company ceased to exist in 2004. ! Beside Uwave ovens.
and
Motorola 1974 sold its television business to Matsushita Electric, now Panasonic

the above will work ch.3/4 VHF with video sources.

The Quasar VV-2002 only has an NTSC (analog tuner). Very few stations with NTSC transmitters are still broadcasting. Only low-power stations were allowed to continue broadcasting an analog signal. Unless you are very close to one of the transmitters, your TV will not tune in the station.

You'll need to connect the TV to a digital-to-analog over the air converter box. (The low-end ones that were free or cheap with the government coupon are harder to find; a few models are still available.) These convert the ATSC (digital) signal to NTSC. Then use an appropriate antenna and follow the instructions to tune in the available OTA signals. Send these to the TV either on the RF or composite Line-in. Set the TV to the appropriate input and use the converter box to change channels.

I hope this helps.

(20" TVs weren't required to have an ATSC tuner until 2007. Since there are reviews for the VV-2002 from 2004, it obviously is an older set.)

A "freezing" picture sounds like something other than your television. Do you have a cable box or satellite box attached? They fail sometimes and need to be replaced. (You have an analog TV and "freezing" is a digital problem.)

The LC-42P7M is both. It accepts both digital and composite (analog) inputs.

Analogue.

No,all tvs have CRTS(Tv Tube).Are analog tvs,don't have ATSC tuner inside.

The bang test is a good indication that there are poor solder connections inside the set. If you can solder and are comfortable working inside the set where potentially dangerous high voltages exist even when unplugged, you can fix this yourself. Look at the main board and resolder any joints that appear grainy or have rings. That should resolve the problem. If not, see if there are any changes in the symptoms and update this.

The changes that you mention will only effect you if you use either rabbit ears or a rooftop antenna. The over-air broadcast signals are being changed from analog to digital. If you have cable or satelite service, there will be no change.

From what I see under amazon.com, it does not have a digital tuner.

But the February 2009 turn off is a deadline for over the air only.
When cable companies turn off their analog signals is a different matter. Some may soon, some may wait until 2012.

The gov't coupon program is only good for converters that handle the over the air digital ATSC signals, not cable's unencrypted digital QAM signals.
