Soyo 32 inch lcd tv
Long story short:
Had the same problem with my Soyo.
Thought it was the power supply board problem that everyone else was reporting.
ordered one. Plugged it in. Did not work.
Inspected the Main/Logic board and found what looked like a black button that could be depressed. It is located to the right of main processor on the board. You can't really miss it.
With the TV plugged in, I pressed the suspect button. The TV made a buzzing/clicking noise for a few moments and the stuck blue illuminated power button faded away.
Curious by this, I pressed the power button and low and behold the TV comes to life!
Looks like I found a "reset" button which seems to have fixed my problem.
Thanks Soyo for not bothering to mention that such a button exists.
I hope the rest of you have the same good luck. In the event you are still in need of a power supply board, email me. I have a spare now it seems. ;)

Will not power on
Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
