When power turn on tv goes in to standby mode when you press standby button on the remote control for split second the blue comes on then goes back to standby mode

To get your TV off standby mode, you can try the following steps:
Check the power source: Make sure that your TV is properly plugged into a working power outlet or surge protector.
Check the remote control: Press the power button on the remote control. Sometimes, the TV may be in standby mode due to a problem with the remote control. If the remote control is not working, try replacing the batteries or using a different remote.
Check the power button on the TV: If the TV does not turn on with the remote control, try pressing the power button on the TV itself.
Unplug and plug back in: Unplug the TV from the power source for at least 30 seconds and then plug it back in. This can reset the TV and may help to get it out of standby mode.
Check for a timer: Some TVs have a timer function that automatically puts the TV in standby mode after a certain amount of time. Check the TV settings to see if this feature is enabled.
If none of the above steps work, there may be an issue with the TV's hardware or software. In this case, it may be best to contact the manufacturer or a professional repair service for assistance.

Sounds like your power supply capacitors have failed. Google for Z1234TV and see if you can locate a power supply capacitor repair kit for your model.

Try restting it by unplugging the tv for a few mins and it should rest to original factory default settings but leave it unplugged 10-15 mins to be sure.

New set?
If you're turning almost any TV on by the manual power switch on it, thats Standby mode.
The next step it's waiting for is the ON command from the remote control.
There are two main methods remotes use to go to ON from Standby:
Press the Power button for both on and off commands
Press any 1-10 (or 1-0) button for on, press power button for off.

Hi,

May I know if the standby led light at the front panel is blinking, if so please count how many times it will flash to determine the error code? If not follow the steps below.

In standby mode press the button of the remote control in sequence, " Display ", " Channel 5 ", " Vol (-) ", " Power ". Self diagnosis screen will displays. Le me know the result.

There is a method called a Power Scan this method allows you to search for all possible codes. Try this until you reach a code that carries all of the functions desired. If the TV mode button starts flashing rapidly during this process you have exhausted all possible codes.
Power Scan
1.) Hold down the clear "TV" button on the remote for four seconds, then press 500 pound ( #)
2.) Hold down the clear "TV" button on the remote for four seconds, press the big power button once.
3.) Press the channel up button once per second until the TV turns off then press pound (#).

If it's brand new, it's probably still programed for store display mode.go to settings and switch it off

Download the manual and codes from here

http://www.remotecentral.com/cgi-bin/files/dl.cgi?file=others/radio_shack/15135-manual.zip&area=other

Here is how to set the code...

1. Turn TV on
2. Press TV button on remote
3. Hold P button on remote until LED blinks twice
4. Enter the first 5 digit code for Magnavox TV's
5. Press Power button - TV should turn off. If TV doesn't turn off repeat steps 2-5 with the next 5 digit code, until either TV goes off or run out of codes.
6. If out of codes use searching for code method below...

TV codes for Magnavox

10047, 11454, 10054, 10154, 10000, 10250, 10051, 10180, 10060, 10030, 10171, 10092, 10706, 11913, 11904, 11755, 10019, 11365, 11254, 10802, 10386, 10282, 10020, 10187, 10186, 10024, 10179, 10096

Searching for code

1. Turn on TV.
2. Press TV button on remote
3. Press and hold P button until LED blinks twice
4. Enter code 991 on remote - LED blinks twice
5. Press 1 - Device key blinks twice
6. Press Power button once
7. Press and release CH+ key until TV turns off.

At this point in the manual, the manual is only correct depending on what type of TV you have.

In the manual if you press the Power on button the TV should turn itself back on, the fail to state that not all TV's turn on by the power button, the majority now are triggered to turn on, on channel change, however you can't use channel change here to check it as you'll go to the next code... here is my solution...

8. Turn TV back on either using original TV remote, or buttons on front (most TV's if you change channels they come back out of standby mode, very few now turn on by pressing the power button).

9. Press Power button on remote - TV should turn itself off again.
10. Press P button on remote to lock in that code.

If the device does not turn off press CH- to go back through the codes, press and release P button when TV turns off.

Finding code

If you used the search function you might want to know what code it's using. To do this follow these instructions...

1. Press TV button
2. Press and hold P until LED blinks twice
3. Enter 990 and LED blinks twice
4. Press 1 and count number of times LED blinks this is the first digit of your code (e.g. 1 blink = 1, 2 blinks = 2, etc).
5. Repeat step 4 pressing buttons 2 - 5 for the other digits (e.g. for the second digit press 2 count number of blinks.. etc)

At this point the manual doesn't tell you how to get out of this mode, I presume pressing any other button on the remote other than 1-5 will take you out of this mode, either that or leaving the remote alone for 5 minutes.
