The problem is most likely the the screws are loose on the inverter boards. The screws must be tighted as they provide the ground to the inverter bds. The inverter boards are undet the shields on both sides of the unit after pulling the back cover. One way to make sure that you are losing back lights and not video is when your picture goes black, shine a flash light on the screen at an angle and will see the video is still there. This mean the back lights are out. If you do not see the video it may be another problem

The power supply is having difficulty. The typical cause is
underated electrolytic capacitors. I would examine all the caps
(round cylindrical cans) in the power supply and see if any of them are
bulged. Not a bad idea to just replace all of them with better
These type of caps have all kinds of specs. Not just voltage and capacity, but also temperature, case size, and obtuse stuff like dissipation factor. Most all power supplies use switching type designs that run at serious frequencies (not the old 60 hz - more like 50khz) that stress out these electrolytic caps and many circuit designers (or their cheap bosses) don't specify the better parts. Replace them with the same capacitance, but higher voltage, and higher temp parts (hopefully they will not be too big physically).
Ya, I know you paid $$$ for this TV and they scrimped on cheap parts. Yup, the more expensive a product is, the more pressure the bean counters put on keeping the price down.
Hope Ya Fix It.

Yes your inverter is bad, I have the same problem my set is about 1 and 1/4 years old. Because Olevia makes a terrible product there inverters are attached directly on to the panel, which means they will only sell the inverter along with the panel i.e $700+ to replace + $100 dollars labor if u don't know how to fix it ur self. I am currently searching to find the manufacture that makes the inverters because olevia will not disclose that information. I believe it is darfon, if so the inverter should cost about $150-200 depending. If you dont believe you can fix it ur self ur best bet is try and sell the set for scrap take ur $100 or so dollar and buy a quality product! Oh and dont call there support they will tell 10 different things before u find out this long for seen truth!

I had the exact same problem and I fixed my Westinghouse 32 inch by replacing the power supply. You can purchase it at
I takes about 15 minutest to replace. Just take the back lower panel off and replace the power supply. Mine works like new now.

The lower "Y Buffer" board is defective. Best repaired by a technician, or contact Phillips support for the part if you think you are able to replace a small circuit board on your own.
