Hi.

If it is completely off, then the power board has probably failed.

Try disconnecting the TV and connecting to a different power outlet, eventually use an extension.

If still no luck, then it is usually a faulty power board.

The board gets replaced after testing the power cable.

The cable can be tested using a multimeter. Cable is unplugged and multimeter set on ohm is used on power cable, with one probe on outlet side, and one probe on TV side, for each of the two wires.

If power cable is OK replace power board.

Parts for most models available here.

Regards.

My remote wont work,tryed new batteries its for a lcd tv,dvd player


Try to check the battery terminal specially the one that is connected in the pcb, Then if you have a cellphone with a camera try to point the led sensor in to the camera lens then try to push any buttons and look at the monitor of the cellphone if you see a red light that glows it is indicating that your remote is in good condition, if there is no glowing red light it is indicating that your remote sensor is defective try to replace it but observe the polarity.

When I turn on the TV the blue indicator light comes on but there is no display, then the blue light starts blinking.


The following steps should be able to correct the problem:
1) Unplug the TV or remove AC power from the TV
2) Count to ten and then plug in the TV
3) Locate the [Menu], [VOL-] and [Power] button on the TV’s side panel
4) Using the buttons on the TV’s Side Panel, press and hold both the [Menu] and [VOL-] buttons.
5) While holding those buttons, press and release the [Power] button one time and count to 3 before releasing the [Menu] and [VOL-] buttons.
6) The TV’s lower left Blue Power LED will come ON.
7) Wait 30 seconds. Confirm that the blue LED on the Lower Left of the TV (not the iPod dock for iPod models) has remained ON during this time.
8) Press the [Mute] button on the TV remote twice
9) Unplug the TV or remove AC power
10) Count to ten and plug the TV in
11) The TV power should automatically come ON and the blue power LED with be ON
12) Wait 40 seconds and the TV picture should appear
13) You can now continue using your TV.
14) If the picture does not appear, power on the TV manually:
· If the LED begins flashing, unplug and power ON a second time.
· If the LED begins flashing again, power ON the TV without unplugging
If the LED begins flashing again, contact us directly by phone to obtain a local authorized service center for you.
If the TV does power on, please reply back with the software version number for us to research this issue. Please follow these steps to obtain the software version number:

1) Press the [Menu] button on the remote control.
2) Using the arrow keys in the center of the remote, scroll over to the "settings" menu and select the [OK] button on the remote
3) Scroll down to "system info" and select [OK] button on the remote

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.

Remote works occionally


dear,

the easiest way to check all remote buttons is here
just open the camera of ur mobile phone or any other digital display camera.
place your sensor (IRLED) of remote infront of the camera so that u can see the sensor from ur camera.
just press each button one by one and u will see light emitting from that sensor in your camera.
if all button emitt light then it is confirmed that remote is ok, the problem is in tv reciever (Photodiode or phototransistor).
but see the light intensity. is it glowing high or low.
if low then u have to change the health battery.

regards,

dont forget to rate it, it should work
