Magnavox 19MF337B/27 won't autoprogram

Main board fault. Contact any service technician. Gopakumar Gopalan Google

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!

U the remote to turn to the channel 3.

You will have to run the Autoprogram menu function from the menu. Here are the steps

Press the MENU button on the remote control.
Use the cursor down to select Installation in the Settings menu.
Use the cursor right to enter the Installation menu.
Select Autoprogram in the Installation menu.
Use the cursor right to enter the Autoprogram menu.
Press the OK button.
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.
Make sure that registration with your cable TV provider and connection of equipment are completed.
Press the green button “Next” on the remote control.
Press the green button “Start” to start autoprogramming.
The menu screen disappears and the progress of autoprogramming is displayed.The progress bar indicates the number of analog and digital TV channels found. (Also digital channels via CableCARD are being programmed.
When Autoprogramming is complete, a message appears confirming the completion and the TV switches to the first installed TV channel.

make sure that ur antenna/catv is properly connected to antenna/catv input of ur tv...better check the center lead if ur using coaxial cable..then try to reprogram/autoprogram ur set.
navigate also on tuner settings...via remote..

try to adjust at the vertical section.hope this will help

sounds like it needs to be switched to cable mode. go in to your menu look for something like STD Cable.

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.

what is your problem plz tell.

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.
