Question about Televison & Video
Hi We bought this a few months ago and it it was very good, but suddenly we have no picture only sound. I have turned it off at the mains, unplugged, tried everything. This morning the picture came back for about 10 minutes, then disappeared again. I saw somewhere that it could be the 'inverter'? Guess this means a call-out since I'm not techie. Thanks for any help.
LCD sets (most) use back lights for the light source--the inverter mentioned likely is for them----in a very dark room with set on and or with a flashlight look to see if you can see a FAINT image on the screen, if so backlights are either bad or no power reaching them.

Please be aware that this a big problem on this unit. The insulator material used by sharp to between the IC's on the AV board both on top of the boards and underneath the the AV pcb is failing. This insulator is mounted to the IC and under the metal heat sinc. Remove the back and pull the AV Board out of the unit. Use zylene or alcohol and clean all of the grey insulator from between the pins on the ic and order the replacement insulators from Sharp. Most times this will correct the no sound problem. Sometimes this has also damaged the AV pcb and it will have to be replaced. The parts that should be replaced come in a kit with sharp part # PSPKIT663WHZZ. If the kit is not available the 2 parts needed are PSPAZA663WJKZ AND PRDARA216WJFW.

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!

Aquos has the same problem. I'm not sure how I discovered this, but
when I lean the TV forward and hit the power button it will turn on
every time. If the screen blacks out and I don't lean it forward when I
hit the power button, the screen will just remain blank. It is very
weird, but at least repeatable.
- Thank you, Guest. That did it. It definitely seems to be a problem with the TV. Tilting it and hitting the power button helped me get the video back.
