I have samsung LN46D6000Sf will not come on No Lights are on when pluged up

1. Make sure the back lights are OK, to do so, unplug the cable between the power supply & the main board, apply the AC power to the power supply, if the back lights are OK, it should light up.
2. If the back lights are OK, i will try a new main board first.

Sure the plug is getting power from wall outlet? If power is there you might want to check out the power supply board first for issues.

The lights run off of 12V DC and use your RV's batteries to run when not plugged in. When plugged in it uses the AC and converts it to DC and runs the lights.

Please check your battery disconnect switch. It's most likely off. In my Winne there is a battery disconnect switch which disconnects the two batteries near the door. Lights wont work when unplugged and the switch is off. Lights works when plugged in or unplugged and switched on.

Hello,

When you say the power cable I hope you mean the cable that comes from the main control module under the chair. I want to make sure you are not talking about the AC power cable that plugs from the chair to a wall outlet. So if we are on the same page about the cable is the one going from the joystick to the main control module under the chair and all you do is plug it in and the green speed lights start to blink this would indicate the joystick is bad.

lets try something...take the computer and unplug it ..then remove the battery...with the battery set aside plug the wall plug back in and plug that into the wall outlet....then hold down the power button for about 2-4 seconds and let me know if it turns on or if there is any changes
then try a different power cable and if that doesn't work then the problem is with your motherboard....you can attempt to reflow the board by taking it all apart...make sure you remove everything that can be heat damaged...cpu ect.....then take aluminum foil and make 3inch soft balls out of it to suspend the motherboard so that it doesn't touch the cookie sheet pan....then bake at 400 for 10 mins...and after that if it still doesn't work then you need to replace the motherboard

If you are looking for a control board for that model let me know I have two working boards.

When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.

Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.Maybe your DC Power Jack which is where the power cord plugsinto the computer is bad. Take an ink pen and push the tip inside thejack and see if the little pin wiggles, if so the jack is bad. You'll have totake the laptop apart to fix it. Most times it is soldered onto themotherboard, so you will have to desolder the old and solder a new one.

then the orange light mean you pluged it in to charge

install windows again
