Does the tv Sansui have high definition mode?

Check its main power regulator section circuits for any defective components. If you are not well experienced, it will be dangerous to touch these part of the circuit.

The DTV2784 has a SDTV tuner and is ready to receive digital broadcasts, but it is not HD(high definition).

Hi, first of all you need a high definition source. I'm not sure if your cable box is HD but lets take it as an example. The component leads which you are using isn't 'true' HD video quality, what you need is a hdmi cable from your source to your TV.

Your cable box maybe HD with a HDMI output, if it is then you need the lead to come out of the cable box into your tv's HDMI input using a HDMI lead. Then you switch your TV's source to the HDMI input and it then should be producing a HD quality picture, but to truly get the full HD experience you may want to subscripe to a HD channel or purchase a blueray player becasue most cable TV channels are upscaled to HD and the definition is not as good as on a blue ray disc or a true HD channel.

So in conclusion the cable and input you are using is not designed for HD input. I believe your TV is HD, check for HDMI inputs or DVI inputs.

Hope this explains your problem

Okay - it is a high def 720p but you have to use the HDMI inputs for High Definition... also, using the LCD as a computer monitor the best setting is 1280 x 768 - standard p&p monitor driver for Win XP or Vista (or Win 7 Beta). The HDMI slots are on the left side and are small rectangular slots about 1" long.

HDLCD2600 come set for cable. Make sure the tv is set for "tv" or "air" then run the auto channel memory or search feature of the set. If you have the manual it's under "memorizing channels". If your still have problems, call Sansui TV's customer service number 800 289 0980.

This happens when you have a video signal that the TV does not recognize. If you have an High Definition source such as a Blue Ray Disc player, High Definition Set Top Box, Or a High Defintion Gamming System than use the HDMI output of such device, connect a HDMI cable to this output and put the other end into The input of HDMI on the TV. Make sure you have this device on before you select the input on the remote of the TV or the TV will say NOT Supported Mode.
