No the switch if working fine. It is a momentary contact switch. Check the air vents all around the tv, Vacuum the vents if possible so air can circulate. Next there is a protection circuit built in to the system called to power on self test. if test results are ok the tv will go on. If not the tv may go on but flicker on or off and then no tv.
The power supply board is notorious for failing that way. Some can be replaced most have to be repaired to the component level. Try the Vacuum first before opening it up cause it is a lot of work on the dining room table, There is a small power relay that is located on the power board which actually controls the main A.C. to the whole set. I have seen them intermittent before causing that problem but it has to be soldered in place and a lot of electronic components can be destroyed by just you touching it. Be careful, Good Luck, Bill

Try cleaning the 11 element lens just in front of the lamp housing. If this doesn't completely clear the problem, then one or more LCD panels are faulty.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
