Hello -

The remote control for your Vizio TV probably has a Closed Caption button. Is there a button with CC printed on it? If so, that is most likely the button to press for Closed Captioning.

Hi
Just try with component input, and see whether it works fine. If it works fine with component input, the tuner section in your TV has got damaged. Soem Vizio sets will have dual tuner; one for analogue and the other for digital. Lighning stroke will damage the tuners first, than any other components inside a TV, because it has been alway connected to cable. Check the component video. If it also does not work, the mother board of your TV is faulty. Some type of fault will be repairable. If the fault is serious, you have to replace its main board istself. OK.

Hi Johnson,

Only 50% chance that the symptoms was caused by a lightning strike because your cable box was powering on fine. Most of the cases when lightning strike near to your area, possible of multiple damaged to the electronic device not only to one particular appliances, most especially if they are plugged into the outlet. Also, fuse will blew because of excessive voltage.

I've suspected that the symptoms was only a co-incidence of lightning strike. If you can hear the clicking of the relay, this is only means that the standby power supply is working fine. However, this board has multiple output voltage feeding the other boards to function well. This kind of symptoms is a power supply related problem.

If you have necessary tools and test instrument and handy with electronics, you can troubleshoot this board to find the faulty parts like open fusible resistors, shorted transistors/IC's, leaky electrolytic capacitor, etc.
Another option is to replace the entire power supply board, this is more convenient if you are going to DIY because no soldering required. Try to find you board HERE. Type the model no. of your unit to the search engine, available parts/board will be display.

Hope I helped you.
Have a nice day!
Thanks for using Vr2020.

If you do it through a laptop or computer you will need what is called a streaming device. If you tv is new it most likely has an internet connection on it already and just needs to be hooked into your router to make this happen. A very good streaming device is ROKU but there are several out there.

If you are connected to a cable box the CC is being controlled by the remote of the box.

Usually there is a hot key on the cable box remote if not you can go into settings and under language turn CC on or off.
