SOURCE: Either PSU or Darfon V144 inverter backlight problem?

Hi, Please measure all windings again and see if there is one lower than 900ohm. All CCFL might seem working but only for one second before the protection circuit cuts in. By the way, there is something that I would like to know, what is the type number of your remote control?

Hello,

I think you need to check the ballast. The ballast ignites the lamp. A defective ballast to cause your screen display become dull or dim.

So, you might also need to replace the ballast.

Lastly, power problem could cause this type of problem. When the power board is not supplying full current into other parts of the TV, this can cause the display to become dim. So it is also possible that low voltage circulation in the TV is the cause of the problem. Check the power supply board for any short or obviously bad capacitor or any other component on the power board.

But check check the ballast first, if that doesn't fix things, then check the power supply board.

Good luck.

What you have is a darfon V144 board (junk). it's a simple fix if you know how to use some basic tools and a soldering iron. Get an led (i used digikey's PN: L10041-ND) and solder it from pin 10 to pin 16 on the OZ960 chip on the inverter board. If you need the chip layout type "OZ960 pdf" in google. Hope this helps.

It sounds like you have a power supply problem, this powers the inverter! Where you just replaced the inverter, we could assume it is good! Look for some bad caps (capacitors) on the power supply board. They will look bulged on the top an may be a little leaky (brownish stain). The power supply can fail on some output and be good on others. Was the back light inverter new? If all else fails, see if you can return the back light inverter and get another! I hope this is helpful!!

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!

Screen goes black, sound unaffected. Can be remedied by turning off and immediately back on, but it will do it again and again and again.
