So no sound, no picture, no indicator lights, no nothing?
Two options: blown fuse or bad power-board.
Either way start by opening up you're TV's case. First check for any blown fuses, if you find one, check it for its rating and buy a new one at Radio Shack.
If that's not the problem, then it's most likely a bad power-board. There are ways to check if those are functional or not, but that requires a Volt-meter (cheap) and some know-how. Depending on you TV's model, a new power-board can be very easy to find online for pretty cheap.

If you wanna try any of this stuff, but aren't accustomed to this sort of thing, let me know and I can walk you through it. Remember, there's no such thing as a stupid question.

SOURCE: required output voltages from an acoustic solution lcd television power supply unit

Only the original supply is going to work---schematics with voltages and wave forms are rarely available online except to a authorized service center for that brand---they want to SELL REPLACEMENT boards and not have someone fix them.

What is "flyback" in a tv monitor


A flyback transformer (FBT), also called a line output transformer (LOPT), is a special type of electrical transformer. It was initially designed to generate high voltage sawtooth signals at a relatively high frequency. In modern applications it is used extensively in switched-mode power supplies for both low (3V) and high voltage (over 10 kV) supplies.

this is use only on monitor the old one that used CRT TUBE.

3115cn power supply


"Low Voltage Power Supply" in a laser printer usually means the AC to DC power supply in from your wall outlet. The "High Voltage Power Supply" is often in the center of the printer and provides the high power required for imaging internally.

Screen goes black after 2 sec


The lightbulb high voltage power supply is detecting problem with the low voltage power supply or with one of the light bulbs and shutdowns in emergency. Open the monitor and check for inflated capacitors. Replace all capacitors even if only few are inflated. Light bulbs require further testing empowering them one by one with external high voltage por supply and their replacement is not easy. Have to open the LCD and then it's hard to clean the layers from the dust resulting bad spots on the image. Be careful and good luck.

Power light is blinking and the tv won't power up.


In that case the problem of your television is the power supply.The power supply have low voltage output so that the board of your TV cannot drive,so that the TV wont turn on.The power supply have leak capacitor that may cause of abnormal voltage.The output voltage of the power supply is +5V, +12V, and +24V.So the power supply is the problem its need to repair.Thanks

So you can see at least two bad caps, then you need to replace them, there should be a set of caps for the 5v power supply for the logic circuits and the set of caps for the16~18 vdc power supply for the backlights inverter circuits.

Make sure to use low ESR type caps.

I have lost the original power supply for my dell 1701fp monitor. I have a power supply that I think may work as a substitute until I can replace the original. I need to know, what the acceptable voltage...


What ever you use, it must be REGULATED power supply that will maintain 14vdc output, rating at 3A. These regulated power supply can easily maintain the output voltage within +/- 5% with input AC voltage range from 100~240vac.
Linear regulator power supply may not work since it has slow response time to regulate the voltage.

The power supply of my monitor doesnot work anymore. The blue power on led goes on and off. I have measured the supply voltage of 13,5 V and it goes on and off. With an external supply the monitor consumes...


http://s807.photobucket.com/albums/yy352/budm/Samsung%20205BW/

Attach a 12v bulb to the 12v output of the power supply, do not turn on the power switch because we just wan to lod the power supply with the bulb only, see if the lamp cycle on and off.
Check the DC voltage on the large cap (the one with 250~350vdc rating) on the AC primary side, it should have about 160vdc on it.
Use the hair dryer set to low and heat up the small cap by SMP IC on the heatsink as shown in picture DSCF0585 to see if the output 12vdc is on steady.

All the caps have flat tops and you replace them as a set?

Comes on by itself,shutsdown when i change channels


Try to change the channels without the remote control ie with buttons below the TV set. If it works then you need to get your remote serviced. There might be some stuck keys in the remote.
This may happen at any time or possibly after being on for awhile in which something heats up and drifts out of spec. The low voltage regulator may be letting the voltage rise excessively. Then, a dark picture or video muting during a channel change triggers the X-ray or power supply over-voltage protection.
Monitor the output of the low voltage power supply B+ to see if it is stable as the brightness/scene changes.

PS/2 power supply connection


You seem to have an oddball monitor if what you describe is correct. The power supply to a monitor[Display Screen is that what you mean?] is either direct to main power- in which case the power cord is either built in with a power plug for wall socket, or has a socket on the back for a separate main power cord. Or is powered from a low voltage converter that delivers low volts usually via a coaxial plug like this illustration PS2 connection does dot come into the equation as far as I know unless you have got hold of something unusual. Tell you what take a shot of the back of the monitor and lets have a look see mean while here's is a shot of a typical low voltage power supply available anywhere.
