I bought a Philips digital flat televisions from a hotel . When I press the menu button on the tv all that appears is NOT AVAILABLE. How do I get the TV out of hotel mode so I can acces the the menu etc.?

SOURCE: Frozen digital screen

Set TV to standby and press Info, menu, mute then power. The set should turn on with the service menu available scroll down until you select reset press right hand arrow next to enter and then enter. TV will turn off. When switched on it goes into Plug and Play mode to reset the analogue and digital tuner. Allow a full reset then you should be ok.

SOURCE: menu pops up while tv is on

Isolate the problem by removing the batteries from the remote. If the problem goes away replace the remote: "CHEAP" .
If the problem does not go away, the problem is in the TV, repair the TV "EXPENSIVE" !

SOURCE: Lg hotel tv. t.v. button are locked out, only hotel remote works

Hold down the MENU button on the remote for approx 5 seconds. Then enter 1105 this will access the hidden hotel option on the LG tv so you can change whatever you like..

I've had the same problem with a 32" model LC320EM82S. All the Emerson TV ( no matter what size ) are having the same issue.
I'm sure with your TV, the green light is blinking before the TV automatically turns OFF. Basically, the TV is trying to power up the screen and has failed. Protection mode turns the TV OFF to prevent other parts from being damaged inside.
My solution for fixing my TV was replacing one bad inverter transformer of six on the Backlight Inverter/Power Board. Here is what my board looks like:
You can see the six inverter transformer on the bottom of the board. It's what supplies power to the screen. Your board may look similar. You can sometimes find a whole replacement board over the internet for a good price. Shopjimmy.com is a good place to start. Just start searching by your TV model number.
If you have some electronic experience, you can repair the board itself by finding a Service Manual over the internet for less than $20. It will have all the part numbers, schematics, and diagrams you need. I would investigate the inverter transformer for your problem.
I hope I helped you out with your problem.

If you cannot find the remote control at all, you will need to reprogram the EPROM IC. This IC is inside the tv, with numbers starting or in between 24c02.... Please contact any qualified tehnican for further help. The IC i mentioned is programmed and at present it is locked through Hotel Mode. Also try to look RESET switch, to reset the whole unit. Thanks
