It could be a number of things, mostly power board and main board.
Power is relatively easy to rule out if you can make simple voltmeter readings.
Look for "how to test" at http://blog.coppelltvrepair.com and there'll be plenty of examples.
Your power board is most likely not going to be there, but the principles are the same for all boards.

The unit has a fault on its power board and sustain board.

SOURCE: 23 inch lcd tv by dell wont turn on as if no power
if this is a DELL W3201C read this.
Have the same model and same problem
probably It is a bad inverter board, in my case one of the 16 transformers is burnt out on the inverter board. still trying to find a replacement component. if not replacing the board is the only option or getting the inverter board repaired.
by the way, this TV has a Samsung panel: model LTA320W2-L03. so it needs parts for a Samsong not a DELL.
DELL does not manufacture or fix them becuase they don't make them
SOURCE: Element FLX 3202 no power
This was the same thing that happened to me. When I took it apart and checked the power supply the capacitor (largest on the board) was blown. I called Element Electronics, which turned out to be Polaroid, and they sold me the entire control box assembly for appx $115 with a $100 core deposit to ship my old assembly back. My core deposit was credited back to my account within 2-weeks. BTW, when mine went out I had no power light on at all. Lastly, If you have questions about doing this yourself let me know, while I'm no electrical engineer, I did a ton of research trying to solve the problem.

If TV does not remain in standby and turns on itself then power switch on top of it could be defective and power supply board is also suspected. Take off its back cover and unplug top switch connector just to confirm is that cause of On-Off its own. If problem still exist then power supply board has problem and will be replaced. Let me know the results to move forward.
