Vizio 70" E701I-A3 - Picture went out like *snap* th

Does the menu look ok?

Blue screen could be a bad main board or a no signal issue---do you get picture with DVD player connected?

For the cheap guy like me who will probably do more harm than good:
Also check for the F3 Fuse on that same main input board. It is located in the upper right corner. Hard wired fuses; very small. You will see F1-F4 (F4 is empty). You can solder a replacement fuse right over it. I would recommend piggybacking the fuse with a fuse you can replace. Will need the holder and a new fuse. 6 bucks.
Doesn't solve problem, but I can go another 2 1/2 years and the wife won't blame me for screwing up the TV in the first place.

your set is in the SAP mode go into the cutomer settings and locat the sound setting and turn it to stereo

Yes, changing the main board should correct the problem.

The exact size for this and almost all visio TVs are: M4 x 35mm at .70 pitchHope this Helps the next guy/gal that looses their screws...

Power doesn't have to be knocked out for a cable box to destroy the HDMI ports on a TV. Thunder miles away will put voltage spikes on the cable system which in turn trashes the main board in the TV. You can get parts for your TV here: TV Parts Universal TV Stands DLP Chips ShopJimmy

you have to make sure voltage is getting to the Power supply board, if you know how to check for the 110-120v ac at the board and that there is no line fuse in between. If you are getting power at board then I would make sure the PS are good. You also can check to see if you have voltages going to other boards, Inverter boards go bad in this set alot, but you should still have logo light up white or amber, To get it right you must check voltages, carefully.

This is the fix for the Main board repair :
Locate IC 32 small 8 pin surface mount near top of Main Board and remove. Short pin 2 to pin 5. (pin 5 through 8 are together and pin 2 and 4 are together)
You will need a good TV Tech to do this for you.

After only three days I would take it back, or at least take the remote back and try it on a different sound bar.

Visio might not have a headphone jacks at all! Look around your set and, probably you won't find jack marked as headphone. You might need to use wireless headphones, what have an rca plugs and connect them to audio monitor out on your tv set.
Good luck!

The T-CON board is out.

If I'm understanding you correctly this is a two-day old television? If that's the case it should be under warranty, return it to the vendor.

If it says "searching for satellite" the problem is in your satellite receiver, not the TV. The TV is working. Its showing you the signal coming from the sat box. The sat box is the tuner and is responsible for the sat signal. The "searching for satellite" is a common problem after lightening issues. If you have multiple sat boxes, then swap this one with another that you know works. If this is your only box, call your provider as it means the dish LNB or the sat box was damaged by the lightening. Also have the wiring checked for bad grounds due to an improper install.

I will check out the back lights inverter board first if there is any defective electrolytic capacitors or not, if not, the problem is the main board.
