Power cords can be bought from most of the electronics spare part selling shops at your town. There is no special attention to choose one. Select a good quality power cord from a reputed brand. that is all.

I NEED a new power adapter ttttttttttoo.. can you HELP please,, I allready had a so called TV repaire Man try to fix it he said he cant get a new power adapter for it to be fixed .... I stupidly PAYED him waited 9 months later, and still no TV fixed..Im taking him to smalls claimes court.....Very un happy persone ,I just want a new power adapter,....please some one out there...peascorn...I have d:sign TV 3032- ad-13d-2...

Hi Steve,
Power on the unit in the dark room then shine with the flashlight directly in the screen, you will barely see the images. This is because your backlight is not functioning. The following reasons are the caused.
1. Power supply - missing B+(supply voltage) coming from this board feeding the inverter board. This is caused by faulty transistor, dried/leaky electrolytic capacitor, open fusible resistor.
2. Inverter board - even the B+ is good from the power supply, if the fuse, driver transistor, driver transformer is faulty no output to the backlight resulting to black picture.
3. Busted backlight - even inverter board is good but if this is busted resulting to black picture also.
Diagnosing the fault is technical and if you don't have necessary tools and test instrument and can't fix it yourself, I would advice you to look for an experienced technician to isolate the problem.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

I have a new OEM power supply for this tv.
If intertested, please email me your contact info.

Thanks,

There you go. Happy throwing!

It's a backlight or backlight inverter issue. (The backlight itself usually fades or makes the on-screen image change to pink/red.) For an out-of-warranty TV, open up the back of the TV and remove the shielding. Look for any scorch marks or bulging or damaged capacitors. (Sometimes other parts will fail on this part but these can be spotted easily. Capacitors look like cylinders on a tripod.)

If you borrow (or have a) high-end multimeter (able to measure high frequencies - 50 kHz) or an oscilloscope, hold the multimeter probes a fraction of an inch apart about an inch above the board and power up the TV. If you see a 1 or an actual value, you have a good inverter. If you see a reading near 0, the board is bad or the multimeter can't resolve the frequency.

In either case, you can buy a replacement inverter for $50-150 and just do a simple swap. Disconnect all of the wires (connections are similar to molex and ribbon cables in a computer) and remove board (a few screws usually). Connect the cables to the new inverter. (If you google backlight inverter replacement, you'll find videos and text descriptions.) Note the part number on the board, including the Rev number, and order the exact one (shopjimmy.com or lcdparts.net are good starting points). Universal inverters do exist but can result in reversed controls (up to lower the brightness). Replacing individual parts on the board is cheaper but more prone to not tracking down all of the bad parts.

If the inverter is good, then it's probably backlights themselves (several in most TVs). These are sandwiched on the perimeter of the TV (usually under some tape that holds the lamp, reflector and other parts together. You need to order by length and width and get ones for your TV size. Remove the tape, and separate the reflector (make a note of how things are put together) then you have to Dremel (or use another rotary tool) to remove the plastic to get the backlight out. (They are often molded into the frame.) Then put in the new backlight and reassemble everything.

With a good spare backlight, you can test an inverter for condition (plug together and turn on the tv while the box is open). Similarly a good inverter can test the backlight.

I hope this helps.

In that case other parts are still in need of replacement. Start by checking the high tension capacitors, followed by the high tension transistor , then the voltages from the low tensions (all of the above from the power source) and finally check the signal board.

is there a screen saver that appears or a No signal popup?
check the connections from the source. maybe remove the source cable and look to see if the no signal screen appears...
if not maybe some damage has occurred.

Check To Make Sure You Have Cable To The House Which Im Sure you Have.

Then Unplug The T.v And Hold On/Off For 30 Seconds Then Release And Plug Back In. When Turning It On Hold The Power Button For 10 Seconds Or Until It Beeps.

Check To See If Problem Persists.
