Question about Emerson Televison & Video
If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

There are a couple of possibilities here. If the set is indead dead,
the most likely culprit is the "standby" transformer. If you are
getting a click followed shortly thereafter by another click, then the
TV is detecting a problem and shutting down to prevent further damage.
And if you get no clicks or anything at all, I would suggest you to look at the fuse and the standby transformer. The standby transformer is a small transformer that supplies 5V to the system even when off to allow remote control. You need to see if the primary side of this transformer is open or not. You should have 5V.

The only solution at this point would be to get the power supply repair since new boards are not longer being manufactured. In about 95% of the time if the LCD doesn't power up or turns OFF by itself or need to be unplug for some time to make work again; those are the symptoms of a dying or defective power supply.

If the circuit breaker was tripped, more likely the fuse inside the TV power supply might also be blown. If that is the case there might be a short circuit in the power supply components, more likely on a diode or transistor/mosfet.
Contact these website to see if they have the parts for your plasma.

Look for the fault in power supply board. First check the fuse and replace it if burned. Then it could be a Voltage Regulator chip(s) burned (they look like transistor with 3 pins). You can test it with multimeter, they could have different pin outs, but generally it should read around 5 MOhms in 2 sets of 2 pins. Or it could be bad capacitors, look for swallen or domed capacitors; measure them with capacitance meter, sometimes they dry out with time. Or it could be other parts in power supply.
