I have a new Sharp LCD 55" Aquos, bought in Dec. Had some problems in March this year, warranty covered the issues. Issues being, TV will shut off & restart, TV will then shutoff, & not turn on at all, lastly,TV will not turn off. TV lasted 2 months, issues have returned. So, I requested a replacement, Sharp says ok, they will send out a recertified TV, guess that means used but reworked. Ok, TV arrived yesterday, I set it up, going smoothly, able to input my SSID & password, now it will not connect at all to my network. My modem is good, my router is good, in fact, those components are not the problem, my wireless works fine thru out the house, for those who have this type TV, knows that Netflix & a host of other online apps are available. I know how to set it up etc. Error message says "Lan not ready, try again later". the manual has ZERO troubleshooting guidelines on online problems. My last resort is to connect it straight to the router with a CAT 5 cable & see if I can get online hard wired. Any other ideas or suggestions from anyone experiencing this ? appreciate and feedback.
