Hello, You will need to get into the tv's menu and change the "settings" area under display properties to read "normal" instead of "Zoom". Change that and you will be back to being able to see the entire display. Good Luck Rich Lilja

try to browse on google..

what lights on front of set are on and or blinking?

If you're using an external cable box or the like, you'll need to tell it to output in 16:9 or 16:10 (widescreen). This should be found in the menus somewhere on your cable box. Probably under settings (surprise surprise). Once you've done that, with any luck you're TV should be able to adapt to the new widescreen video signal it's receiving.

Hope this helpes

Good day!!!

normally,,that problem is caused of failing capacitors on the boards..

This is example picture of capacitor:


Follow this procedure on how to fix your TV..

1. open the back cover
2. look at the chassis/board inside your TV.
3. try to look all capacitors inside..it likes the picture above..
   
4. look at the actual image if it has a leak on oil/bulged on the top..
5. try to replaced it with the same type,ratings and value.using soldering iron and soldering lead.
   
6. after you replaced the bad capacitors..try to power it ON again to test if it is OK.

please watch this video for guide on how to replaced bad capacitors on the board.

I would try this remote at the store on the same TV to see if it works there so you can figure out if the TV will need to be repair or they should give you a new remote, or the remote needs to be programmed.

Please leave rating if it helps.

It is under warranty, have it check before warranty runs out ASAP because you do not want to have something else goes wrong either.

It's kind of hard to answer your question with not knowing how your hooking up your TV. If you are hooking up a antenna or cable to your RF in you need to make sure you have your input set to TV and autoprogram your channels. If your using a cable box hooked to your RF in then you need make sure it is on and autoprogram your channels. If you are using a cable box, satellite receiver, or DVD player hooked up to your component, composite, or HDMI.input then you need to make sure you have you input set for that. Hope that helps.
