Not very likely to be the switch itself, the switch is a tactile momentary switch, more likely to have failed power supply due to bad caps just like the rest of failed monitors here, check to see if your adapter is putting out 12vdc, then we need to find out if it is getting 12vdc all the way to the main board and the inverter board:

The LED in my motherboard is on, but if i turn on the switch, their is no response. the power connection is correct. but it doesn't work


Try swapping the power button connection with the reset button connection. Then to turn on your computer you will need to press the reset button. If that works you have a faulty power button. Otherwise try using a different PSU. One that you know works. If that doesn't help the motherboard will have to be replaced.

It's quite likely your unit had a blown thermal fuse caused by a bad thermostat. Test them by disconnecting one end and a meter should show continuity if the part is good. The pro's test them in circuit while the unit is plugged in, power showing across the part means it is bad. REPLACE BOTH PARTS TOGETHER.

Unplug the set and hold the power button for 30 seconds. Plug it back in and see if that fixes it. If it doesn't then it sounds like there is a problem on the board underneath the power button. Something isn't allowing the circuit to be cut.
