Have TV Questions? Ask a TV Technician
Hi David and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, bear with us; re-confirm and post back with the complete model number of the "... Lg smart TV( model webosTV)..."
Appreciate the additional information.
Is this a fresh/new install? ...or has the TV connected wirelessly with the modem before and this issue of "...TV doesn't pick up our wireless modem..." just recent?
To my understanding, this particular model has a 'status test' in Home / Settings / Network / Wi-Fi Connection / Advanced settings that would show an "X" mark to identify the potential problem between: TV / modem / DNS / Internet
Can you please determine where the "X" mark is please?
Were you able to get to 'Wi-Fi Connection' at least?
Depending on the network version, are you able to manually set an IP Address for the TV?
No the name would alsmot be the SSID while the IP Address would be something like 192.256.254.1
There is a RESET for this model in Home / Settings / Advanced / General / Reset to Initial Settings
A reset is both a test and a try of a fix. As it implies, a reset would force the unit to revert back to factory defaults removing glitches and config errors but would include memories, presets and user preferences. After a reset, the initial setup would have to be performed.
Would you consider this?
With the TV yes, consider the RESET. As posted above; "...A reset is both a test and a try of a fix..." If not corrective and based on "...only recently that the TV doesn't pick up the modem..."; then we are looking at a potential hardware issue.
Then it would confirm a hardware issue.
Considering that the TV would still be under warranty, it may then be to your advantage to have it repaired by an authorized Service Center.
Please post back how you would want to approach this and/or should additional information be needed.
I understand David.
Good luck and thank you too for the opportunity to be able to share the information.
