Good job finding the problem.
Can we see the pictures of the IR board?
The IR board runs on 3.3V or 5V?

and it runs at 3.3 volts replaced c1 and c3 smd cap.

That is probably why the 1117 you found was hot.

Re: Vizio D650I-B2

okay figured it out it was the ir board for remote it was loading down main. tv works good now

Just received this same set, exact same symptoms and solution. STBY voltage was going from .8V to 1.5V. Disconnecting from mainboard and get steady 5V. Once I came across this thread, disconnecting the IR board from the mainboard and got steady 5V and would power on with the power button.

Now I gotta find the replacement IR board... gonna put this sucker on my kitchen wall, lol

Can you explain to me what you have done? I am experiencing exactly the same issue. I replaced the power supply and the main board assuming the same issues brought up. Can you explain your fix so I can try it? Should I replaced the ir board long story short?

Re: Vizio D650I-B2

Maybe unhook the ir board and see if tv works with button board on tv if there is one.

Re: Vizio D650I-B2

Can also test those 2 caps on ir board, check m in ohm mode.

Re: Vizio D650I-B2

No replacement available. Am not familiar with replacing these caps would try by myself but they seem to tiny and I have no experience in this field. Wouldn't even know where to get these parts. Anyone know of a place that could repair this for me or where should I even start?

Man you are awesome!! Thank you so much. I really appreciate all the help. I would eventually really want to learn how to work on my own parts. Is there any videos or training guides I can follow to learn this?

One there for putting them on: https://www.youtube.com/watch?v=f9fbqks3BS8

Re: Vizio D650I-B2

Some de-soldering techniques there, one simple way is to just use two soldering irons, one on each side, there's a bunch more videos there too: https://www.youtube.com/watch?v=HZLQzBOOQbw

Re: Vizio D650I-B2

Phenomenal work! Had the same problem. Thought it was the power supply. Followed your post and fixed!

Re: Vizio D650I-B2

Hey guys new here, seeing if anyone is still on this thread willing to try to help. I have this same TV with the same problem up until the low fluctuating standby voltage. The TV just quit turning on and has no standby light. I am getting a good 5v standby, 12v and 24v in there corresponding pins on the power board. unplugged the IR board just to see, no change. Ive just run out of resources, trying to figure out what voltages I should be seeing in certain spots on the main board that would hint at an issue.
