Need to program samsung tv universal remote. How do I do it?

For my universal remote control's manual, all of the Samsung codes are:


Also, remember that you can have the remote scan for codes on its own. On the remote just hold the "TV" control button (should be at the top near the power button) and the power button turns on. Then hold the power button too, and it shuts back off; keep holding until it turns back on and then it will stay on. Then, point the remote at the TV (it should be on) and press the power button every three seconds. It will test a code every two or three seconds. When your TV finally shuts itself off in response, you've got the right code and the remote should work.

Samsung model Ln40e550f7f has no sound and mute button is not pm

Check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis. If you wish to get some details; check the site linked here. Pull up older posts. Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Sounds like you need to recharge or replace the battery. If the voltage is too low for the internal processor it will just turn right off again to save any remaining power.

Shutting off and on

That actually is a flaw in the Sansung phone itself, its something in the manufacturing. When getting large messages or multimedia messages the Samsung will power itself on and off. Had the same problem with Samsung.

Samsung washing machine won't complete cycle

If it is shutting off when its in the spin cycle than you either have a unbalanced load or a problem in the shocks that will trigger a false shut off in the spin cycle.Let me know what cycle it's shutting off in.Also if you can catch it right when it shuts off , then immediately try to turn it back on ,if it comes on without hesitation then you can rule out a failing motor .
