you have a broken inverter board. I have a LT30HV, and it had the same problem. The inverter board supplies power to the backlight. Swap it out with a good one, and you're back in business.
To test, take a bright flashlight and point it at the screen just an inch or so off the surface. If you can see your picture, then you have a blown inverter.
it may not be worth fixing it. Wait for a good sale on a new one. My inverter cost about 150, and it was a remanufactured part. Not as good as the original part as it flickers just a tad. I had to take the entire TV apart, with pieces literally everywhere. My cats loved it.

Cheap parts were used in the construction of the olevia. I replaced 2 capacitors that were bad on the power board and the tv works fine now

I have a 24" Olevia LCD TV. Same symptoms (Stdby LED is on, press power and it flashes off, then back on). The USB cable to the Service Port also worked. But being of sound technical mind, I figured this means that the PC is supplying the +5v to the circuit. What I did was disassebled the TV, carefully disconnected all the cables, and opened it up to reveal the circuitry. I looked over the circuit and noticed the 1000uf/16v capacitor at position CS21 was failed and bulging. I removed the cap, tested it and verified that it was indeed failed. I went to a local Radio Shack and picked up a 1000uf/35v electrolytic, after all, the value is what mainly matters as long as it's not lower voltage than the original. I replaced the new CS21 capacitor back in the circuit (it is polarity sensitive, so pay attention to what the original mounting position is). I reassembled the TV and Viola! Works! No need for the USB cable to the Service Port!
I hope this helps someone!
