Magnavox TV problems

When I switch on my Magnavox TV, it just starts displaying all the features of it. I can't change the channels or switch it off with or without remote. Only way to switch it off is to unplug it.

Your tv is in the demo mode. You will need the user manual to get it out of demo.

I have a 50" philips magnavox tv that changes channels on it own and turns itself on frequently. What is causing this issue?


Do you live with someone who likes practical jokes; even silly ones?

There are a number of companies that make remotes that can mess with someones TV or other remote devices.
I have a watch, as a gag, that will self program its remote to operate any TV capable of this feature. With this watch, I can change channels, power status and even reset the TV to factory default state.
Next time this happens, look behind you.

Word Component1 shows up when changing local channels


Your Direct TV box is switching between a Standard Definition channel and a High Definition channel. When this happens, the TV has to switch the display format. As the format is changing, you will briefly loss picture, the TV detects the new format, and then displays it. What you are seeing is the normal operation of the TV. It the TV did not blank the picture, you would see a broken chopped up picture during the transition. If you are familiar with the setup menu of the Direct TV box, you could change the video format settings so than it locks to the High Definition format. If you are not familiar with the Setup menu, you should contact Direct TV and ask then to walk you though this procedure. Specifically, ask them to "Help me set my Direct TV box so that it always displays in 1080i format." You pay for them for the service, they should be able to provide you with some phone support at no charge. I hope this was helpful, best wishes.

Magnavox PJTV model 51mp392/17 -pressing channel buttons changes


You need a professional.
Your TV has "lost is mind"

Stop using the TV until it is repaired.
Continue to use it and your problems will multiply and grow more expensive.
Call the manufacturer to find you nearest authorized service center.

Hope that helps, good luck

ALSO:
I searched a Magnavox manual for the lock feature here is what I found...
The following functions are disabled during SDM (and enabled after leaving SDM):
· Parental lock
· Blue mute
· Hospitality Mode
· No-ident Timer (normally the set is automatically switched off when no video signal (IDENT) is received for
15 minutes).
All other controls operate normally.
Entering Service Default Mode
To enter the Service Default Mode, press the following key sequence on the remote control transmitter:
0-6-2-5-9-6-MENU
Do not allow the display to time out between entries while keying the sequence.
Upon entry into the Service Default Mode, the letters “SDM” will be displayed at the upper right corner of the screen.

ALSO:
- Line 7 : “CHANNEL BLOCKED”
Indicates that all channels are locked except the selected channel.
The following complaints may be generated due to locked channels:
- TV cannot be switched on from standby with the local keyboard buttons.
- “CH+” and “CH-“ buttons on local keyboard do not function.
To disable the LOCK feature:
Select ”FEATURE” menu (with the Remote Control).
Select “LOCK” (with the Remote Control).
Set to “OFF”

Menu will not display


If the channel and volume visual display was not set up on the menu to display on screen , neither will show up even if either the remote or set front button are used. Make sure that the tv button is selected on the remote to access the menu .If that does not work ,then either the batteries are dead or the remote is dead.If it is you will need a new remote,sadly. Then you can press the m button , select sound and then select "display volume" and check "during adjustment". The channel display settings are found on "features" from the main menu. Hope this helps.
