32'' sharp aquos tv will not power up.

32'' aquos will not power up. The tv had not been used for about a month. When I went to turn it on, nothing came on. No lights of anykind. I tried it on another outlet, and checked the connection to the tv. No luck. tried to power up w/remote,same problem.

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.

Testimonial: "The tests suggested may lead to something."
