Question about RCA 14F512T 14" TV

1 Answer

Turns on and off at all times of the day and night

All night long this TV has started turning on and off. I have had to unplug it. When I plug it back in, in the morning I can watch sometimes and sometimes it turns off. It will turn on and off all in a matter of 60 seconds, over and over. The only way to turn it off for good is unplug. i'm having the same issue. Tv keeps scanning channels, doesn't respond to remote. deff should be a recall.

Tv repeatedly turns on & off by itself


Given the age of that unit, It may not be possible to get parts for the unit. The problem you are experiencing sounds like a poor connection on either the receiver for the remote or the main board power unit.

TV turns on in the middle of the night


  1. If the TV has a timer option, ensure it is disabled.
  2. Check the remote control to see if any of the buttons are stuck that may be interfering with the TV.
  3. Unplug the power cord of the TV from the AC wall outlet for 60 seconds.
  4. Plug the power cord back into the AC outlet.
  5. Attempt to turn on the TV.
  6. Remove all remote controls from the room where the TV is located.

TV TURNS ON BY ITSELF IN MIDDLE OF THE NIGHT HELP


If you have eliminated the obvious things the tv must have a fault...

The obvious things - a night prowler with a remote, a cat walking across your remote, a ghost that likes to watch tv, somebody sleepwalking...

It is possible the infra red signal needed to switch on the tv is not coming from your remote. You can test this by removing the batteries or taking the remote to bed with you. If the tv still turns on then tape over the infra red receiver on the tv to eliminate the chance of some stray infra red beam from elsewhere being the culprit. If that stops the tv turning on you need heavier curtains or blinds or the tv moving perhaps, but if the tv still switches on it has a fault.

There is another thought. Digital TVs and digiboxes are often programmed to wake up periodically to check for software updates. Mine wakes up at 3am but it only checks for software updates and doesn't switch on the tv, but maybe this is what your tv is doing.

A further thought - a tv often has the functions of an alarm clock. They have a sleep function so they can switch themselves to standby after you have fallen asleep and then can wake you in the morning. Perhaps the alarm has been inadvertantly set for 2am?

These days it is rather anti-social to leave any appliance on standby. Rather than unplugging the set every night and worrying about the kids, why not arrange for the tv to be plugged in to a switched outlet so the kids can switch it on or alternatively use a cheap plug-in timeswitch to prevent the set switching on in the wee small hours...

TV turns off when you change the channel


sounds like a power fault, prob just weak capacitors if you can change them it would not cost a lot to replace them, when you change channel it draws more power and if its at its limit it will turn off as the capacitors cannot take it. few £'s or $s to get the replacement capacitors, you will probably see the blown capacitors on the power board as the will not have flat tops they will be rounded, change them same for same i.e 16v 330 for same 105c type would be best. it will say this on the capacitor.

My TV turns on and off randomly!


Remove the rear cover & turn set on, pull all the connectors off one at a time and push back on. I have had loose connectors cause this problem, and by doing the above has fixed it. Note do the pull off and push back on of the connectors, with the tv unplugged from the AC outlet.

Power light flashing/ no picture


I have the same problem. The only way to get the TV to come on is to unplug it, but once you get it back on it turns itself off again in a few minutes.
