We have a VizioE420I led smart tv that will just shut off & then turnitself back on at different intervals? we were told by the tv specialist it was the dish satellite box....the dish guy said it was the tv. Well, we got a different tv it it is not the dish receiver. What happened to our tv?

Sounds like you have a bad capacitor. Likely overheating. Likely going to need service or replacement.

Google how to spot a bad capacitor. They pop up and get a brown dot in the center. They are easy to spot.

Finlux Smart TV System 2013 Review ' AVForums

Here is what to check when your TV is turned on, power light is ON, but no picture is seen or sound is heard:

1 - Be sure the component you are using (Xbox, Cable, SAT, ROKU) is turned ON.
2 - Check to be sure all cable and cords are securely connected to the TV inputs and component outputs.
3 - Make sure you are on the correct input as some TV's will show a black screen if there is nothing connected to that input.
4 - Unplug the input you are trying to use from the TV (such as an HDMI Cable) and plug it back in.
5 - Check for signs of damage on all cords and cables from the TV to all components.
6 - Make sure the TV is not in ENERGY SAVE MODE, press the button on the remote control to go back to normal mode.
7 - Unplug the TV for 10 minutes to see if there was a temporary one time issue with the TV.
8 - Disconnect the TV from power for 2 minutes, then when plugging it back in PRESS AND HOLD THE POWER BUTTON ON THE TV FOR 10 to 20 SECONDS to try and force the TV to reset.
9 - If after checking all these different issues, you may have a Faulty Power Supply Board, A Bad Capacitor on the Power Supply Board, Loose Wire Harness, or Loose Ribbon Connector in the TV itself.
10 - Most likely when a TV has the power light ON but NO PICTURE and NO SOUND, it is the Power Supply Board that has failed.

BTW, here are solutions for you to play iTunes movies on Samsung smart TV

LG TV 3 blink code is due to bad power supply or LED lamps in the panel. If you have technical skills of soldering, physically check and replace if you found bulging capacitors in the power supply. If PSU is working, check LED back light strips with LED tester and replace faulty LED back light strip.

LED Smart TV saves Power and Contrast & Colour you will get better than Smart TV.

Set-up (Programming) procedure is too much to type in here, and is not practical and it will differ brand-to-brand remote controls. If you wish to get more; check the site linked here. It has set-up code list & set-up procedure to many popular brand remote controls. Pull up older posts.

There may be some components failing in the power supply or one of the circuit boards that are causing too high a current pull.

I realize that this answer is very vague. Without doing proper diagnostics, it is impossible to guess at something like this.

Out of warranty repairs on these sets can be very expensive. I would suggest that if the set is going to be expensive to service, it would be best to replace it with a known brand name that offers an extended warranty with local service. You will pay more, but you will have dependability and better quality.

it could be high voltage cap located by flyback,if you have back off of tv and turn tv on,you will see green led's turn on,(on the board)if they turn off there is a small blue high voltage cap hidden under glue(i believe it's a 102 cap)that would be the one change,99% of time that is what will fix problem

The most likely reason for the no picture might be the back light is gone and needs to be replaced, now as for the LED light blinking on different intervals is because its diagnosing it self unfortunately the user manual does not have any information on this part only by contacting the Phillips customer support you might get a better idea, but check your back light first it may just be that. Also try to check your Manufacturer warranty repair.
