Tv won't turn on power indicator light not lit


Hi,
As you mentioned the tv have problem with the power supply stage. Before suspecting for any intenal fault Chcek the following first. Remove the AC plug of the tv and connect the same in any other wall outlet. If then also it shows the same problem then its the powersupply board of your tv.
working on power supply board should be done by a skilled worker. Because there is risk of electric shock even if the power is disconnected. some of the capacitors will hold charge even if the power is not connected.

Here i have adde the link which will lead you the powesupply board.

How do i get regular tv channels no cable or direct tv. I have a 32' magnavox model #32MF338B/F7


Hello
I'm not sure about the model number of your TV, as here it is marked as both "27MS343S and 32MF338B/F7". Anyway I gies this solution as for the first denoted.
Insert antena to the antena socket at the back side of your TV marked as 75Ohms antena input.
[1] Press "Menu" button on the remote control handset to display menu on screen.
[2] Press "Vol+ or Vol--" button repetedly to hilight "TUN" [Tuner].
[3] Press "Ch+ or Ch--" button to hilight 'AUTOPROGRAM"
[4] Press "Vol+" to programming tv channels.
Tv will tune and store channels transmitted channels at that time, through entire bands, and will display the first channel receved after tuning process completed. It may take some minutes. You have to wait it to complete. After displaying the first channel, you can select your favourite channel Using CH+ or CH--" buttons. Ok.

Magnavox 42 LCD 42mf438b/f7 turns on/off by itself


Mine was doing the same thing. Update the firmware and it fixes the problem. Updating the firmware is done by downloading the file to a thumb-drive from the phillips product support page then plugging in the drive into the side of your television and turning it on. See your manual for slightly better instructions.
