My Soyo DYLT032 has power but no picture or sound

This cord looks like a regular 3 pin cord used for things like computers, etc. You can get them from home center stores, hardware stores, computer stores etc.

CHECK THE FUSE

1. This may be a fuse blown in the start up circuit or a rectifier diode at the AC input ( the primary side ) side of the main board.
2. In any case this will require a testing of components at the power supply of the main board by a qualified tech. A schematic is require to trace all defective components and replace them about 1 to 2 hours to isolate and repair.

Ur could purchase new power supply at these website.Tv Repair World.com,Shopjimmy.com, Partstore,or Ebay.com.

go to bestbuy they have them

A couple of questions,

What make and model TV.

Are you using a external Digital receiver for digital cable or satellite.

Are you using a surround sound receiver.

I will have a better answer for you after you answer these questions.

I can repair the power supply for you if you like depending on where you live repair is about 150.00 shipping may be a little extra

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.  ;)
