How do I select ANT/cable in on my TC-50PU54. It shows not used

Ckexk that your aerial installation is not damaged, it is possible the cable is damaged. If you try another tvvon it an it does not work there is your fault. It may be that the tuner section has gone but I would definitely try the aerial as the first step to a diagnisis in this case

GOOD LUCK

Yes. It is probably a problem with the internal power circuitry. Look in the circuit board area where the power cord mates with it for capacitors that have bulging tops (instead of the flat tops that are normal). If you see even one, you need to replace all the large capacitors othe power supply section (normally around 5 or 6).

Try relocating the location of your antenna or changing the direction it is pointed. Once this is changed, select PROGRAM CHANNEL from the SETUP menu and set ANT IN to Antenna before selecting Auto to start the programming process.

Check and replace its Z-sustain board. Visit the site named 'Electro-help' for more details. Click this link. View it in "Timeslide" or "Flipcard" option, which can be selected from the drop down box menu by the [Sidebar] tag, at the top left corner of the display window. You can also click the [Home] tab to see the latest updates. It will make search easy. There are more than 1350 posts to different brand TVs now. Pull up older posts there.

are you using the key that came with the car?
key has to be the one that came with car or you have the one that only opens the doors

The tv will only process cable channels when set to 'ant cable' . After the scan, you should be able to view all channels provided on the frequency.
If you want more cable #'s, you will have to pay for those or get a cable box. If you don't find your local channels in the lineup, you will have to use a switcher, or hassle with unplugging and plugging the antenna. This is true for ATSC broadcasts. Please give feedback if this helps. Or tell me more.

Should use remote to bring up the menu. Go to channel search and it will ask you if for ant or cable. This is where you will select for antenna or cable.

Hi,

Initially, pls verify that the coaxial cable is connected to the ANT/Cable/RF IN of the VCR. Thereafter the built-in tuner of the VCR would be used to select the desired channel to be recorded. The VCR in turn maybe connected two (2) ways to the TV:

• Audio/Video using yellow, red & white RCA cables/connectors using AV1 or Video1;
• RF patch cord from RF OUT of VCR to ANT/Cable/RF IN of TV using either Channels 3 or 4.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.
