Question about Vizio L32 32 in. LCD HDTV
My son stuck a USB port into the phone jack in back of the tv then every thing went black. what should i do?
Lol , technicaly it's not possible to plug a USB PORT , into an RJ45 Phone Jack lol
But lets assume he did manage to do just that.
A. Land Lines in the united states phone system use -48 volts of electrical power.
B. USB ports that provide power to USB devices use +5 volts of electrical power.
What you have described to me would suggest to me that your USB port has been overloaded
by the input of a much higher voltage sourse ( the phone line )
Some suggested steps
1. completely unplug the computers power cable for approximately 15 seconds.
2. plug the computer back up and press the power button.
If this fails you may now have a defective motherboard or a blown power supply.
You have some options at this point.
You can change the power supply and see if that solves the issue
If a new power supply does not solve the issue
you will need to change the motherboard.
My advice on changing the motherboard is that you replace ONLY the motherboard first.
If more things like the Memory or CPU are dammaged , you will then replace them as needed.
I feel very dissapointed that your son was unable to accomplish his computer hacking goals lol
perhaps when he is older he will make a fine Engineer.
Thank you for using FixYa!
