Question about RCA Televison & Video

Open Question

I have a RCA TV model # 27V512T set comes on picture and sound ok for about 3 seconds then it shuts down. For the past 3 or 4 months if I would turn on 20 to 30 times it would come on and work fine until it was shut off but now won't stay on now. I do have a technical background and used to repair TV's but that was a along time ago, any help would be greatly appreciated. Thanks Mike

Sounds like a thermal breakdown of a componet. it could be in the main power supply regulaor supply or even a bad capacitor in the power or sweep supply. In some cases Zener diodes can break down and change values after warm up. In some cases also bad solder connections in the highvoltage section, or the power supply can cause this problem. It is a hard call without being able to look at the set. Just a few leads on where to go first. most likly a combo unit, such as this one , would cost you more then a new one these days. Good Luck PS Please dont forget to rate this thread.

You can download a PDF from here: http://www.servicemanuals.net/results.aspx?type=SM&brand=0&model=50EX20B Make sure that the coolant is not leaking out onto the printed circuit boards. i have had the remote sensor cause this problem before and also I have had bad capacitors in the sweep and the main power supplies. Good Luck

SOURCE: TV Shuts off

The most common cause for what you are seeing is a shorted gun in the picture tube. When 2 elements (heater and cathode) of one of the guns inside the neck of the picture tube touch, that gun goes full on and overloads the flyback (high voltage) transformer. If it is in the blue gun, the screen will go bright blue with light blue "retrace" lines in it. The computer senses the overload and shuts the set off. At 2 years old the tech most likely tried removing the short by arcing between the elements. This works sometimes but the short often comes back a few months later. Another attempt at removing the short could be tried, and it might work this time, but it may or may not work for long. The ony other solution is to replace the picture tube but that would cost much more than the set is worth. A qualified tech will be able to tell you if this is the problem in your set.

How do I turn off the fpa lock on my rca 27V512T without a remote control.


Hello

Most RCA and GE TV 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.
  4. 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.
OK.

You don't need the remote to unlock the TV. Any RCA universal remote will change channels etc if you want a remote.
Now from the manual: simultaneously hold down the menu/OK button and the Volume down button for 3 seconds. This resets the pasword and unlocks the TV. You can then enter the menus as usualI believe to control/clear parental settings etc.
