OK the chevron light in the front of the set is it blinking?

Expert:  Anthony_Infotech replied 7 months ago.

When it switches off that is?or does it just drop to standby OFF?

Customer: replied 7 months ago.
only when the tv is turning off and on thoughp
Customer: replied 7 months ago.
Now it's just stuck on a blank black screen. That won't take any command
Expert:  Anthony_Infotech replied 7 months ago.

Is the set connected to the internet?

Customer: replied 7 months ago.
Turns off for a few seconds then turns back on and looks like this

Expert:  Anthony_Infotech replied 7 months ago.

OK but you do for sure see the light on the front of the set go off or blink?because that will imply the set is at fault and eliminate any box you may be using

Customer: replied 7 months ago.
Yeah it blinks off and back on only when the tv is turning off and back on
Expert:  Anthony_Infotech replied 7 months ago.

How old is the set now please?

Is there any warranty with the set?

Customer: replied 7 months ago.
Well I bought it from Best Buy earlier this year as an open box set they had on the floor
Customer: replied 7 months ago.
I didn't buy a warranty thru Best Buy.. So maybe a one year warranty thru sharp just depending on how they honor their warranties

Most suspect is bad firmware if you click the link above and drop half way down page teh firmware itself and the guide is there ahowever it should have updated itself over the internet but check it out anyhow to make sure you have the latest version of firmware , if that angle is covered then I suggest you exercise what warranty you have as they will swap the main-board, if you run into red tape let me know and we will discuss if you can do this yourself, outside of that if you are not comfortable with that you will need a tech www.tvrepairpros.com will locate a tech in your area

Expert:  Anthony_Infotech replied 7 months ago.

The set is ON and OFF?you will need to check when the set is ON and running, if the set is now none operational then the main-board will need to be replaced , frustrating but thats the way it is I am afraid hopefully you have warranty and the warranty covers you here

Expert:  Anthony_Infotech replied 7 months ago.

If they do not cover you for whatever reason then the only option is to replace mainboard yourself

Please though do make sure its the TV going off itself and not the box that will starve the set of a signal and you will get it going black and no sound similar to what you are experiencing

Expert:  Anthony_Infotech replied 7 months ago.

Do you need more help?

Customer: replied 7 months ago.
I'm still kind of confused on what my actual issue is
Expert:  Anthony_Infotech replied 7 months ago.

OK what is the exact status of the set now?is it working\ or not working at all\ or working sometimes then not working?
