My remote can not do any action of my home theater system in spite of red light running every time I click a button. Mother is a problem in the system or remote? I would love to get help.

I'd look for the manual and see what it says about that red light. I can't find squat for "Magnavox KM42010P".

Hello, Cheri Torres with DISH Network Customer Service here. I came across your post and would like to help! I will list here for you the best codes for 20.0 IR remotes for Sony DVD Home Theater Systems as well as the instructions for addressing your remote to the system. I hope you find this information useful and if you have any further questions or concerns feel free to email directly at Cheri.Torres@Dishnetwork.com.

Codes for 20.0 remote
2846, 2784, 2765, 2766 and 2500

Instructions for addressing your remote to your Home Theater System

1. Press and hold the desired mode button until all mode button back lights come on, then release.
2. Use the number buttons to enter the device code corresponding to the equipment.
3. Press the POUND (#) button.
   
   If the code entered is valid for the remote, the mode light flashes three times.
4. Test the functionality.
   

There are a few possibilities. 1) You have the system on wrong broadcast system. Press the TV.Sys button on the remote. (In the US, you need the NTSC (analog) broadcast for older TVs). If you have lost the original remote, you need a replacement that matches the feature. See http://www.remotes.com/remotes/servlet/rs?a=gmi&uuid=12937326385240&smodel=DVD505&brand_pn=COBY_DVD505 for a substitute remote. 2) You have mismatched cables/inputs.

For the second issue, a composite video cable could be connected to a component video input. If both devices have component video, get a component video cable (red, blue and green for the video, separate red/white cable for audio); it isn't included with the player. Otherwise connect to the composite (AV) connections on the TV (yellow for video, red/white for audio).

If needed, you can reset the player as follows:
****RESET THE DVD PLAYER BACK TO THE DEFAULT SETTING***
1) Open the DVD tray.
2) Press the "Setup" button.
3) On the "Down" arrow, press it three times.
4) On the "Right' arrow, press it once.
5) On the "Down" arrow, press it three times
6) On the "Right" arrow, press it once, then press "Play/Sel" button.
7) Press the Setup button to exit.
*The default setting will take affect as soon as you press the setup button (step 6).

I hope this helps.

if the light is red that means that is off, so try to turn it on, that will help and if it doe not work just unplug everything and run the setup again, sometimes the system lose the configuration

1 Turn on SE-FX65 2 While pressing [>>/>>'] ] press the numbered button [3] on the remote control until "P" lights in the home theater unit's display The indicator on SE-FX65 turns green. 3 While "P" is displayed, press [I/D SET] 4While pressing [>>/>>'} press the numbered button [3] on the remote control.
This worked for me. I moved and lost the FX65A, and Had to buy a replacement off ebay,
Used this manual http://www.specsserver.com/CACHE/FRQUJVMNXTYS.PDF but I have to give mosyzlak props, cause he gave me the idea to look for it.

Make sure your remote has all new batteries. It might only be running a partial side of remote. Test the battersies?

a blinking or pulsing power light usualy means a problem with the power supply. Check for burned resistors or swallen capacitors on the power board it will be the one with the one with the main power running to it.

With the home theater system off, press and hold the REMAIN button on the home theater's remote control for 5 seconds.
Note: You can release the REMAIN button when the POWER LED blinks blue.

With the wireless module turned on, use a ball point pen to press the RESET button on the back of the wireless module. The POWER LED in the front of the home theater blinks two times.

Turn on the home theater. The LINK LED on the front of the SWA-3000 changes from red to blue, indicating the wireless module has connected to the home theater.

If your home theater continues to display rear check after you have tried the steps above, call Samsung Customer Care at 1-800-SAMSUNG (1-800-726-7864). Have your model number and serial number on hand to set up service.

The code I used is 0449...I have a STS20-S Venturer Home theater

1. With the home theater system off, press and hold the REMAIN button on the home theater's remote control for 5 seconds.
