Menu problem The problem that I'm having is I can't use my menu at all. Every time I press the menu button, the tv sound goes off but the menu does not appear. What can I do?

Have you checked the TV without other devices connected to the TV.
Eg. disconnect any home theatre or speakers from the TV.

Verify with audio menu if the settngs of TV speakers is on or off ?
To adjust the audio settings:
1. Press the menu button on the remote. The on-screen menu
is displayed.
2. Use the arrow buttons on the remote to highlight audio and press ok. The AUDIO menu is displayed.
3. Use the arrow buttons to highlight the setting you wish to adjust, then press left/right arrow buttons to change the setting:
• TV speakers - Turns the built-in speakers on or off.

Lastly have you tried restoring the TV to factory default settings.
To restore the TV to its factory default settings:
1. Press the menu button on the remote. The on-screen menu is
displayed.
2. Use the arrow buttons on the remote to highlight system
and press ok. The SYSTEM menu is displayed.
3. Highlight reset & admin and press ok. The RESET & ADMIN
menu is displayed.
4. Highlight reset TV to factory defaults and press ok.
5. If you have changed the default parental control passcode,
enter it now.
The TV displays, "Select Reset to restore all TV settings to
factory defaults and clear all account information."
6. Highlight reset and press ok.
7. Wait for the TV to turn off. The TV will turn back on shortly
afterward and the Setup App will begin

In my openion, Its problem of hardware in your TV and signal processing circuits are involved. It might be problem of Firmware (programe to control the performence over all) Philips can advise you better in this regard.

Depending on your TV, here are the generic steps Toshiba has outlined to reset your TV:

1. Press the MENU button on the remote (or MENU on the TV) to open the Setup menu.
2. Using the arrow keys on the remote (or volume / channel on the TV), highlight INSTALLATION at the top of the menu and press ENTER. A new set of INSTALLATION menu icons will appear.
3. Highlight the SYSTEM STATUS menu at the top.
4. Highlight SYSTEM INFORMATION below and press ENTER.
5. At the top of the SYSTEM INFORMATION window, use the arrow keys on the remote (or volume / channel on the TV) to scroll Left/Right through the menu bar to select FACTORY DEFAULTS. Press ENTER.
6. Highlight YES and press ENTER. To cancel the reset process, select NO and press ENTER.

Sharp Aquos LC-32L450M - i have recently baught this LCD, but I think the 'mpx' ie the multiplex sound is not working. there is this 'mpx' button on the remote, but wen i press it nothing really happens. in the manual its only written in one line "mpx- multiplex sound" . please any one can help me ..I m really not happy wit the sound right now. paid so much & no good sound its bit irritating please any one help.. wats the problem

press OK on the remote and OK on the TV panel at the same time, after 5 to 10 seconds, the service menu EZ adjust should appear.

another step is to press menu on remote and menu on tv at the same time..

Check all the buttons on the TV and see if they all feel the same. Some times a stuck button can cause the problem

Is this a new problem, or has it always displayed this "X" ?

litigation- O.k if your tv is cycling through the menu ect. it sounds like you have a bad tact switch.Try pressing the contol panel buttons repeatedly,most of the time the remote is used so the tact switches go bad. Try this out ,it may help to clean the contacts. Just make sure you press them alot,it helps most of the time,if not you may wind up in the repair shop.Have fun and let me know. cooltek Mar,4/08

One of you control buttons may be stuck. I found this problem once.
