screen randomly goes black, then comes back?

my vizio tv is quite old. i would sat about 5 or maybe 6 years. its a 42 inch smart tv. its always worked great up until about 2 weeks ago i noticed that when i was playing PS4 the screen went black for maybe 2-3 seconds then came back on. in this time i could still hear the sound, but the picture went black. it only does it once in a while. so at this point its not a huge problem, but id like to repair it before it gets really bad.

"This might not be a problem with the tv, it could be more or less the PlayStation or even the cable that you used causing the problem, I'd suggest starting with getting a new HDMI cable, if that seems not to work, then look at the teardown guide and make sure everything looks in place, and even look in the port, make sure there's nothing odd looking inside of it (TV and Playstation).

I have this exact issue with my 55” vizio that is about 5 or 6 years old and it happens with everything!! Cable TV, Xbox, etc. I’ve tried changing HDMI cords because that seems to be everyone’s answer to this problem but that just doesn’t work. It’s driving me nuts I don’t know how to fix it. I’m about to just buy a whole new TV.

"One of the responses to my complaint said the power board needs replacing. I have not yet looked how much the part would cost, but will before Monday. If the price is reasonable, I’ll replace it myself, unless the manyfacturer is willing to do it for free.

I also got a procedure from Vizio via Text message:

“Let's try a power cycle.

-Power off and unplug the TV

-Press and hold the power button for 20 seconds

-Plug the power in

-Power on the TV”"

I would say, search your TVs model number on eBay and look for a power supply board. Usually a power supply board is anywhere from $15-$30, and a main board could be $25-$50. Start there, after you've taken the TV apart to look for bad capacitors and generally just burnt places in the boards.

Experts out there, could this be the TV or monitor sending info to home base on use?
