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, budmrtn@aol.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

Good day.

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

I hope this solution will be helpful.Thank you for using FixYa.

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.

How do i do factory reset on hisense tv ive gotsound but no picture i tried a hard reset i cant watch movies either


Should have worked after the hard reset. Your problem could be with the leds or the inverter board. Do the flashlight test.

Hisense 50k22dg should i replace led strips first or power board


I would inspect the power board for mushroomed caps and brunt traces. A edge lit led screen has two ribbon cables coming from the power supply, I would unplug one at a time to see if one side lights up. Both led strips rarely go bad at the small time. The problem is most likely in the power supply.

My Hisense 50H5G LED TV has sound but no picture. I did the flashlight test and saw an image. Does this mean the Tcon board is bad?


No it means you have no picture, you must do the testing to decide if the PCB is defective or not.

If the back light is CCFl type; check and replace all CCFL lamps and back light inverter board.
Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

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.

If you see an image with a flashlight the T con board and power supply board are good. The back light controller board is the culprit.
