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: Philips 47PFL3603D LCD TV - TV not responding to remote

One thing you can do is take your cellphone's camera, point the remote at the camera, and press a button. You should be able to see the infrared sensor firing.

If you can verify that, your remote's fine.

In this case, what you have is a bad IR sensor board. The part # is:
313926859182. Right now, there are so many of these things failing, that finding the original might be difficult.

Don't fear, though; it's a small part. And, best of all, it's cheap. Expect to pay around $5.00 for the part, maybe a bit more, maybe less, depending on the supplier.

Now, if you are handy with a power drill (fitted with an octagon/star bit for the back of your set), you can remove the 20 or so star-bit screws from the back of your television. Don't worry about putting the set on the floor. If your TV is on a stand, simply turn it around. You'll need to remove the stand screws, but you won't need to take the TV off of the stand.

Now that you've taken the screws out and removed the back cover, look in the lower left hand area of your set. You'll see a 4 inch long circuit board with 2 cables running to it. Pull the cables out (they'll come out easy). Remove the 2 star-bit screws.

One of the board's sides is under a plastic tab. Lift the board out of its slot from the other side.

Put your new board in, reconnect the two cables, reassemble the back and you are set to go.

Expensive repair for a few bucks and a better IR sensor.

*****************************************************************

This advice assumes that the control buttons (power, volume, channel) located on the side of the set still function. It also assumes you are able to use those buttons to power on the set and verify that you still have a picture on the screen.

default would be to unplug for 12 hours or sometimes there is a little pin hole reset hole type button very small that you have to stick a pin or paperclip end into on the front by the power button, hold it in for 5 sconds sometimes this will reset if not get a new remote a universal one.

The sky remote will not operate the volume on my grundig gu22dvd have tried all the usual things codes etc but still doesnt work


Try an auto search with the remote, you might have already tried it :

1. press tv

2. press select and the red button simultaneously untill the LED light flashes twice

3. Then keep pressing the TV and Standby buttons one after the other (not at same time) until the tv swithches off, then press select to store the code, the LED should flash twice to confirm this.


Once you have the remote working the TV, you can get the remote blink back the TV code so you can write it down for future reference.

  • Press the TV button on the Sky remote
  • Hold down Select and the Red buttons together for approximately two seconds until the LED blinks twice
  • Key in 9, 9, 0
  • Key in 1 on the numeric keypad and count the number of times the Red LED blinks. This is the 1st digit.
  • Repeat for 2 and 3
  • Note: no Blink = 0 (zero)

I locked up my set by mistake need to unlock it and adjust channel for directv I lost my remote use the front keys which caused initial problem tried to adjust volume hit channel key


Hello

Tounlock your TV you surely need its remote control. Try to get it from somewhere, from any one of your friends, who own the similar model of TV, or buy it from RCA. After getting it try the following. You can unlock it.

Most RCA and GE TV sets use a four digit code to control the v-chip. The code reset procedure is different depending on the model. Try each method until you find one that works:
  1. Hold down MENU on the remote and VOLUME DOWN on the TV it's self at the same time for at least 4 seconds. The set won't say so, but the lock will be unlocked
  2. Hold down the 0 on the remote and the VOLUME DOWN buttons on the TV its self at the same time for at least 4 seconds. The set won't say so, but the lock will be unlocked
  3. Hold down the MENU button on the front of the TV and the TV button on the remote at the same time for at least 4 seconds.
  4. Hold down GO BACK on the remote and MENU on the front of the TV at the same time for at least 4 seconds.
  5. Hold down EJECT on the front of the TV and the MENU button on the remote at the same time for at least 4 seconds.
Depending on the model, one of the methods should unlock the V-chip. Now, if desired, you can change the settings on the V-chip by going to the MENU and going to PARENTAL CONTROLS, or on some sets, going to MENU and then going to TV SETUP, then to V-CHIP SET.
Sinotec:
If you have the original remote (RC-A07) for Sinotec tv, then press and hold down the Music button for about 10 seconds
