    I have a magnavox tv less than one year old and this morning when I turned it on, after just a few seconds it turned itself off. I tried over and over again with the same results. I unplugged it for awhile-no change. What could this be on a gently used tv? Please help-I can't afford another one. Linda

How to unlock the television to turn on model 27gt624


Most GE sets use a four digit code to control the v-chip. The code reset is different depending on the model. Try each number until you find the one that works for you.

1. Hold down the MENU button on the remote and VOLUME DOWN button 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 (zero) button on the remote and the VOLUME DOWN button on the TV itself 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 button on the remote and MENU button on the front of the TV at the same time for at least 4 seconds.
Hold down EJECT button on the front of the TV set 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.

After my 70" tv is on for a period of time, it turns off and won't come back on for a while.


Good Day, Connie ss;
The next time the TV turns off try this:
This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source) 1. MAY BE INTERMITTENT, SELF-DIAGNOSIS ERROR 23 OR 24. CHECK SOLDER CONNECTIONS AT CONNECTOR "DY" ON THE YOKES. 2. SHUTDOWN AT POWER WITH SELF-DIAGNOSIS ERROR 23 OR 24. CHECK C411 2200 UFD 35 V AND C412 10 UFD 50 V, BOTH LOCATED ON THE MAIN PCB. I hope this was helpful, good luck, big IRISH.

Vizio LCD 37 Inch Turns Off Randomly


I had a similar problem with my 32 inch plasma tv. I called vizio's
1 800 number and the guy said to unplug the tv from the wall and hold down the power button for a minute and then plug the tv back in outlet and turn on. And it works I guess from what I understood from his heavy accent was that the tv retains power and this resets it somehow. hope that was helpfull!!
