A suggestion: unplug set and try to turn on again; if power light blinks does it blink in a sequence?
3 blinks repeated will mean a problem in the Convergence area.
5 blinks repeated will mean a short on the 140 volt line.
These are the two most common error codes.

I have tried everything that people suggested and I have not fixed yet I hae not changed fuse. Light blinks 3 times.
Three blinks means short and 98% of the time it is in the convergence circuit; repair requires getting at the chassis, being able to solder and parts cost on internet would be under 25 dollars.
I do offer on the Market Place here step by step instructions for this repair in this set; If you wish that kind of help look for SD TECH in the Market Place area of this site.

I have unplugged the set several times and disconnected the HDMI cables. If I let the set sit for about 20-30 minutes and plug everything in it will turn on.
