It seems your "power regulator" a small unit inside tv device has damaged due to wrong power supply. In this case usually the power capacitor burns and few other electronic components like triodes. Get the help of a electronic chip technician to replace the damaged components.
Hope it works.

I would suggest to start by measuring the voltages from the power supply to the main/back light circuitry. If the voltages are low or jumping up and down, that means a defective power supply.
If the red light is blinking, the power supply has a shorted component.
Let me know if you need further assistance.

Hi, the power surge has destroyed the power supply board that is located inside your lcd cabinet. this board works in conjunction with an inverter board that regulates the raw ac current that is used for many different functions in your set. Normally, this type of damage will be isolated within the power supply but, it could have spread to the main control board as well, depending on how well the surge protector preformed during the surge.
The good news is that, this is a repairable situation. you can replace the power supply circuit board and inverter board as well. these replacements will fix this issue.
please rate and god bless:)

The ware to buy information will be hard to come by hence that manufacture for this product does not use a part number on every single part when servicing the unit. Thus I can recommend where to take it and whom to call for more information since this is a unit that i personally do not repair for my clients anymore due to the aftermarket of their parts and how expensive it is getting them ETC. Here is one solution find someone on Ebay.com that is saling this TV dirt cheap and take the parts from it at your own risk! or you can go the manufacture route by calling this number 1-866-289-5168
I know you came here looking for part numbers and more help then this we understand as experts but to tell you to do something that can harm you or go beyond our scope to get these part numbers, because the part in this unit don't go by that would not help you and us and the cost of the assistance would thus go up surpassing the $9.99. I only can diagnose and check on a solution based on your problem, Yes Fixya does have solutions that do Fix but in the case we can only recommend and I would encourage you to rate my assistance based only on recommendations to solve a solution only,

Hello, If there is a complete darkness on the screen, it is likely that the problem is on the card that responsible for providing backlight to the screen. Known as invertor. Sometimes the causes are: 1 loose contacts across the card. 2 the main ic that is number begins with OZ .3 More rarely missing of the 24V voltage that provided to the invertor, in this case you should check the power supply. I hope it was helpful!
Let me know if more help is needed.
