Facing TV Problems? Ask a TV Technician.
That will be SV470XVT or SV471XVT
Sorry , not sure what happened here , wasn`t supposed to post here .
Can you give me the TV's model number ?
O.k then that's a sharp tv and you say that it stopped working after an update ?
How did it do its update , through the cable system or you already had it online ?
O.k then I got something for you to try ;
Pull out the power cord at the mains and then press and hold at the same time INPUT and VOLUME DOWN directly on the tv while you plug back the power cord.
Let me know if it comes on with the letter K on the screen
Source and input are the same thing
O.k then if this procedure doesn`t work and from what you told me so far then something went very wrong with this tv .
No worry though , you can simply pack it up and take it back to the store where you bought it for an exchange or refund , not a repair if it is less than a month since you bought it
This is beyond some sort of reset now , you just tried the ultimate reset for these sharps .
