SOURCE: TV SCREEN GOES BLANK

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!

SOURCE: TV Picture Goes Black

I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions

SOURCE: continued from no picture no sound just clicking

HI, this is total power supply failure. you and a dual power supply unit that, universally, powers all devices directly. there are no ballast in this set so, you will have to replace the Power controls and the fly-back transformers as well. this will fix this unit.

My 55ld520 screen goes black, turn off for short time comes back on but then goes black again.

Start simple by using different cables, whether they be HDMI, VGA or standard COAX cables. They could be losing the connection. Also, it's possible the power supply is wearing out and it gets too hot. You might want to simply try some spray air duster type thing to clear out any dust that can make it hot.

Picture & sound go on & off every sec, red light blinks 5 times

helloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.
