Facing TV Problems? Ask a TV Technician.
Hi and welcome to the site, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.
Initially, bear with us; re-confirm and post back with the complete model number of the TV. The "...DU-52px12xd..." is reported back as an invalid product number.
Appreciate the additional information.
And would you have the service / programming remote (not just the user's remote control) ?
Also did a controller / tuner module came with the TV ?
Yes, the service remote would be necessary.
I would suggest to take pictures of the settings/configurations while in the service menu.
Enable all the options while still in Hotel Mode and then as a final setting, set "Hotel Mode Operation" to "No"
...still as inquired above, did a controller / tuner module came with the TV ? an LST-4100A.
Also, a friendly reminder; change only the Hotel Mode settings. Any and all other changes may and can cause the TV to be completely inoperable.
Please confirm that the service remote is available and was used to turn off the hotel mode.
"Analog 6" would indicate that the TV is now set to analog TV channel 6.
Please post back with a clear picture of the different settings of the Hotel Mode. Click HERE.
