    We moved to our new house and my magnavox big screen was working fine. We hit the power button and it comes on for a few seconds turns off and the led light just blinks three times and goes off and comes back on. Sometimes we get lucky and the TV will actually come on. Then some days it just blinks and sometimes it works fine. HELP.

    Thank you, Jose X from Germantown Maryland.

I think in that brand of tv may be some dry- solder . if you can you have to check it after disconnecting the power cord , under the tv
board if some solder is "dry " - for philips , is it normal to happens
if it is you have just solder again  to make electric contact- delfo

I have the radion shack hdtv remote. Cat no


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.

Mitsubishi wt-42413 Power problem


Okay try to distinguish if the three blinks is 1 pause then 2 blinks or 2blinks pause 1 blink. As the set will only blink a two digit code 12 meaning no error detected and 21 meaning the set is hutdown due to xray protection.

TV auto shut off-power indicator light blinking-won't turn back on


You could have gotten an electrical surge that put your set into a shutdown condition and unplugging the set and letting the Microprocessor reset will fix this problem if it dosent blow out the main power regulator as you still or might I say have a regulator IC problem. IF THIS PROBLEM HAPPENS AGAIN MORE THEN A FEW TIMES WITHIN A SMALL TIME FRAME I WOULD HAVE THE SET LOOKED AT BEFORE THE REGULAOR BLOWS SOMETHING OUT!!!!
