In some cases these TVs were to be returned for exchange. As costs were excessive. If this TV is out of warranty and you have no place to go with this TV, you might just have a hobbiest open the darn thing up. I would say you have a bad capacitor or two in the power supply. This is at its easiest repair. If not you may have a bad LCD panel and that is not worth replacing! Hope I could give a something to work with. Thanks for asking!
You will have to run the Autoprogram menu function from the menu. Here are the steps

Select Cable or Antenna in the Installation mode.
When Antenna is selected, the TV will detect antenna signals and will search for antenna TV (NTSC and ATSC) channels available in your local area.
When Cable is selected, the TV will detect cable company supplied signals and will search for cable TV (NTSC,ATSC, QAM modulated) channels available in your area.

On many televisions with built-in tuners, you have to tell the tuner whether it will be connected to cable or antenna, since the RF spectrum is different for these. Make sure you have cable selected (assuming you are connecting to the cable service) and then try the autoprogramming again.
Get a universal remote or go online and order a replacement original remote for your model. Then use the remote to enter the menu, unlock any child locks, make sure the set is in standard cable mode and do an autoprogram.
