SOURCE: DELL LCD TV locked up w/screen message "main menu locked"

without a remote and disabled keypad keys, the only other option, is to open the unit up a physically RESET the TV. remove the cables from the power board. i believe it has a phillips head screw. careful when you separate the rear cover from the front cover. there is a board screwed in the lower right corner, there is a connecter and a ground cable screwed to the rear cover. take your time prying on the rear cover. once you separated the two pieces, look for the light yellow board with your AC power source. Unplug it for 30 minutes and repeat the process. while your at it, also look down to the lower left side of the monitor. u should be able to see the keypad. press each button, while pressing, look to see if the button is pressing against the circuit board. it may be loose, try this test, u just may be able to fix your keyboard as well. hope this works out.

SOURCE: insignia tv will not powerup

Nothing at all? Does the screen seem to go from dark black to a lighter shade of black?

If the screen appears to stay on the darker shade of black then it is broken, and needs to be sent for repair. ( ie the screen isnt powering on when the tv is and there is nothing you can do without opening it.

You might try unplugging all cables and leaving it off with no power for a day This is in effect performing a factory reset.

and this may sound stupid and patronizing but is the TV being taken out of standby mode and actually switched on?

SOURCE: I bought a 32LC5DC Lg

The only thing that would cause this is a lock!

If you ever forget your password, key in ‘7’, ‘7’, ‘7’, ‘7’
on the remote control.

If unlocking does not free up the unit menu then the unit has most likely had a software upgrade at some point to disable these functions permanently. This is normal hotel based systems in order to prevent them being used if they are stolen. In this case you will have to contact LG directly with Model no and Serial No details to get them to assist you.

If this is happening on all the channels I think you will need a total reset. If so open menu and check the settings for child lock when you manually tune. An option is to reset the channels once again after the lock is opened. Choose a new channel scan to reset the memory. However if the lock seems to be only on specified channels you can open the settings of the channel and unlock on the menu.

TV IS IN LOCK MODE


Try this. If you have a Hisense TV and it happens to be stuck in "child lock" mode (blue screen displaying the words "child lock") you can try to fix it by holding the "CALL" button on the remote for a few seconds.

Alba hd tv, no remote and the child lock is on just need to bypass it model no lcd3288ohdf


Okay - this is a secret child lock that Alba puts onto their tvs - not the child lock accessible via the menu which is 0000 as default. Basically there is a childlock built into the handset. Basically if you hold the menu exit button for more than 10 seconds the handset locks - all that happens then is when you press buttons you will see the blue panel flash on the tv but nothing works. This lock happens when the remote falls down the side of the settee or your child gets their hands on it!!! To unlock, find the menu button on the right hand side of the TV panel and hold it for 15 seconds and the menu screen will pop up - Really important you hold for 15 seconds before releasing. Then simply press the menu exit button on the remote and 'hey presto' - you have control of your TV again! Kind Regards, BIG BAD JON !!!

Got a small bush lcd tele i turn it on i get a blue screen with the word lock on


Try this
Try this...Press standby button on the remote to switch on the TV. Now press Vol- button on the front of TV while pressing the "7" button on the remote. If the lock has been successfully removed you should see a "OK" message appear on the screen.
If that doesn't work, try...
On the front of the TV...Push the volume + and -, OR, channel + and - at the same time and hold for a couple seconds, this should let you access the osd. If you can get to your menu through the buttons on the panel...immediiately go to the child lock and disable it.
