My tv the on off button is blinks 3 time the does nothing

what is the model of your tv?

In standby mode (red led on/after the led stops from blinking), press "Display", "5", Volume (-)", "Power on" on the remote control in sequence, self diagnostic screen will be display, let me know the what is on the screen to diagnose where the fault came from.

dear user,

your tv supply capacitors are weak kindly change it if you can

sounds like u have a bad mainboard.

O would need the model number to assist you, as the s blinks is an error code, but error codes are model specific.

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.

My tv wont turn on. It tries to turn on the green light lights up 3 times then nothing. what is wrong?

Check your CRT boards on the end of the tubes for burn spots, and burnt components, check the resistors to make sure they are not shorted, burnt, and they read the correct resistance. Check the diodes to make sure they conduct in one direction only and are not shorted or open.

the error code will be a blink code from the led it should blink a couple times vbriefly pause and then blink again. Count the blinking led in between the slight pause.

From your post I understand that the tv is not turning on even if you use the button on tv, if that is the case there is nothing wrong with the remote control, and from the blinking light shows that there is something wrong with the tv. Get it checked by a qualified service guy.
