The 24vdc is turn on by the signal from the main logic board, it is not always on, the standby 5vdc is always on. So yes it can be the power supply board is bad, but just to besure we need to find out if it is getting the turn on signal from the main board first.
You can have 24vdc at the inverter board and it will not light up the CCFL until it gets the signal from the main logic board to turn the lamps on (this is the STANDBY condition, the TV is on but the screen in not lit up util it see the video signal).
Send me good clean and clear pictures of the power supply board, email@example.com, connectors of the Power supply, bottom side of the board, then I may be able to tell you which pin is a control input pin. Most people will just throwing parts in and hope that they one of the parts will fix the problem. Used Power supply module for this TV is over $100. http://www.google.com/products?rlz=1T4GGIH_enUS282US283&q=delta+DPS-379AP&um=1&ie=UTF-8&ei=USsxTKn3J6TonQfFlJGEBA&sa=X&oi=product_result_group&ct=title&resnum=4&ved=0CCsQrQQwAw

Testimonial: "Bud helped me fix my TV! It was only 1 1/2 years old. I was looking at a repair bill close to $300 - $500 and I fixed it with a $60 board! Thanks!!!"
If you already replaced a new inverter board and T-con board and the problem is still there.Try to play the video on the DVD,if the video is OK check the cable connection and try to run auto scan.
If the problem is still there check the input supply of the system board or main board it should have 5vdc and 12vdc,if it is OK replace the system board.
Review this manual page 4-1 abnormal display http://www.scribd.com/doc/36875894/Olevia-232-S12-SM

Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
