This LCD might have a defective power supply. I would suggest to open the back cover and inspect the power supply for swelling/bulging capacitors that are located near CN801.

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Not sure if this will help, but most caps fail with the in rush of power, over and over. Sounds like they were not made right. You might try a UPS ( uninterrupted Power Supply) this may help you with dirty power from your power company. And with high spikes. Make sure you get one that will handle the TV current draw. As far as upping the CAPs keep the same or slightly high voltage and increase in uf. You might find one that has the same uf and a higher voltage rating that will handle it.

If the tv has more than one input, you should try switching to the other one. If it has another output(s), you should try the other output(s).
