To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

i had the similar problem. i'm not a tech but like to take stuff apart to find the problem. on my tv i took the back completely off. do not touch the boards. if you follow the power supply from the plug up two boards i found a small white adjustment screw. it was just up and to the right slightly from the plug. with a small screw driver i turned it slightly to the right and the flickering and delayed picture went away. couldn't tell you why it worked but it did. hope this helps, saved us $800 to buy a new tv.

Power LED light indication blinkings or completely dead?Yes,than the power supply board is the causes.That the board,where the power a/c cord plug in to it.Take the aparts,replaced the power supply board,will sold this problems.Tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

no it is your power supply it may have primary power but if you look closely you will see several puffed up capacitors these blow because of the fet near by let go and is not avail you can get a new supply for about 60 bucks from ramplus.com get the fsp number off the supply ex fsp-194

I HAVE FOUND 2 2200uf CAPS ON THE POWER SUPPLY BOARD THAT ARE PUFFED UP. CHANGING THEM USUALLY SOLVES THE PROBLEM. THERE'S ALSO A RESET BUTTON ON THE MAIN BOARD YOU MAY NEED TO RESET AFTER CHANGING THE CAPS.

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.  ;)

Replace all bad capacitors(end raised up) on power suply's main board. That'll fix it. fixed mine :)

Oh my God. I just finished talking to the rep mentioned below. She was nasty. I've been waiting since July cause they don't even have the part in stock since then. I will almost quote this person: "Okay Mam, I don't have to listen to your complaints, your only option here is to keep waiting and I really don't know when the part is going to be back in stock or even if it is going to be in stock again. There is nothing else we can do for you". So what do you think. I paid for a one-year lasting tv and a quote for repair. I was even willing to pay for the part and the excessive shipping charge to get it, but they don't have it. I can't believe there is nothing we can do about this.

This is the "so gentle" lady's information. One thing I know, I will never buy a Soyo again, and will persuade anyone wanting to buy one against it.
