Good day

the problem of your unit is on the power supply...the power supply is the that gives supply to all of the board that TV have....
I give you some tips to perform a troubleshooting...this solution is for D.I.Y and simple trouble shooting only...if this is not successful the trouble of your power supply is major and its very difficult to repair..
so if that case happen I suggest to purchase a new power supply..

your power supply looks like this?

no power to tv through - bugoy31.jpg


first,you have to remove the cover of your TV..
secondly,after you remove the cover..the power supply will reveal and remove it to perform trouble shooting by unscrewing it
thirdly,check the fuse..if busted replace it and check some shorted transistor and diode by using multimeter tester...
fourthly,also look for leak or bulging top capacitor..if found replace it..also check the open or change value resistor..
and finally if you found any defective parts test it by plug in the ac supply to your power supply unit and check the output voltage...if you got 5v,24,and 16vdc it means that your power supply is OK..and if not,your power supply got a major trouble..your option is to give it to the qualified technician or purchase the new one..

if you are purchase a new power supply I give you a web site to order..

Can you use a power cord from a Samsung 39 inch flat screen on a Samsung 65 inch flatscreen


yes, most tv's that i know of take two types of power cords, both of which are ok to mixmatch. As long as the new tv uses a molded u ground cable (3 holes on female end) or the smaller ones (2 round holes on female end) which most do it is perfectly safe to do so. As long as the tv did not have the box attached to cord ( regulates wattage) if that is the case you need one that supplies the EXACT wattage to the tv but i have yet to run into a tv that uses a power cord like that.

Will power cord for ld3255vx work for ld4655vx wide screen tv?


Dear Cheryl,
The power cords are pretty standard from all theses TVs.

Please remember that these power cords have 3 pins (male side), being 2 flats and 1 round that connects to the wall. On the other side it also has 3 flat pins cast into the plastic/rubberized female side. These are standard power cables for the majority of the sound/video equipment you will find in the market.

If the connector at the TV (male) is of the same type in power cord you have (female), in other words, if it fits and completely locks in, then, YES! Go ahead and use it. There is no problem whatsoever.

IMPORTANT - BEFORE CONNECTING THE CORD TO THE WALL ("live" power), please test if your connector fits the TV set completely.
I hope I have helped you.

Is the red light suppose to stay on when you turn off the tv with the remote?


Yes it is supposed to stay on. This is the standby light. The television still draws power as do many electronic devices when not turned on and when in standby. If you do not want the red light to stay on you will have to unplug the television.

I do not have a power cord, can I buy one?


yes... The NEC Plasma TV uses a "standard" PC power cable.
Any computer store (BestBuy) will have one.
Standard size is 6' ... you should get at least an 8' power cord.

Less than $10...

If you have a desktop computer (or parts) try that power cord.

Hope this helps!
