I entered my FB login ID & PW and it does nothing. If I click on News Feed, etc., it just takes me back to the login screen. Anyone else have this problem?

My vizio recently did the same exact thing. Vizio sent an HDTV tech out to fix it and it was the power board. He put a new board in (took 15 min) and the tv works like new.

may be a mainboard problem. If you can see the orange light it usualy means that there is power running through the TV... usually inverter boards are a problem when you do not see any backlight at all.

You have faulty electrolytic caps in the power supply section of the tv. Capacitors with reduced quantities of electrolyte take longer to charge compared to normal ones. That is the reason its coming on after you repeat the on/off sequence a few times. If you are not good at soldering, replacing the power supply should do the job. It should cost you about 75-100$. Let me know if you want to do it yourself(please get me the model number of the set as well so that I can find you a replacement).

When you say there is no signs of life, do you mean that the LED at the front does not come on as well? Also when you press the power button on the remote does the tv make a single "click" noise? Please provide this info so that we can start the component level diagnosis.

Hello,
The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.
The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board. You might be lucky it's just a blow fuse. Also a defective transformer can cause your TV not to power on.
All these can be checked on the power supply board.
But more often bad capacitors causes problem on the power supply board. I do not think the power board needs replacement, rather those defective capacitors is causing this issue. Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.
The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)
You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.
What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).
You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor(capacitors) most likely the normal operation will be restored. Or you can by a refurbished complete power board to save you some stress.
Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.
If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.
I hope this helps.
Regards.
