I am trying to turn off a sleep timer that is built into a rca universal remote

Other RCA VCRs have had problems with flashing timer lights. Those could be fixed with service from an electronics repair person if it doesn't stop even after being unplugged for a while. But, try leaving it unplugged for a few hours. If that doesn't work, the electronics repair might be the way to go, or get a different VCR on eBay or from the local thrift store for pretty cheap.

Universal remotes have have very few options, just basics such as volume, channel, mute, power. Sleep timer will not be there. for that you need to get the original remote.

Electronics Equipment Repair Center

Programming the Sleep Timer:

1. Press and release the TV key.
2. Press and hold the SLEEP key for three seconds. The illuminated component name turns on.
3. Release the SLEEP key.
4. Using the number keys, enter the desired time in minutes (from 1-99 minutes). To set the timer to an umber under 10 minutes, first press 0 and then the desired number (e.g.,05 for five minutes). The illuminated component name blinks with each key press.
5. Once the second number is entered,the illuminated component name turns off.
   Tip Any key press other than the number keys is ignored. If you don't enter the sleep time within 10 seconds after pressing the SLEEP key, you must start over at step 1. The illuminated component name blinks four times and then turns off, indicating your attempt to program the Sleep Timer has been unsuccessful.
6. The Sleep Timer is now set.
7. Leave remote aimed at the TV. Once the Sleep Timer is set, you can continue to use the remote without affecting the Sleep Timer. However, because the timing mechanism for the Sleep Timer is built into the remote itself, the remote must be in TV Mode and pointed at the TV to activate the Sleep Timer.
   Note: If the ON·OFF key is pressed, the Sleep Timer is canceled.

when on sleeper on,while switch off and again if on,the sleeper on Timer cancel.

Using the menu/options button, check whether there is a sleep timer. You may have accidentally set it, and it will shut off the tv at either a particular time, or after a period of time has elapsed.

In most cases you can set the sleep timer by accessing the menu. Or if it is a learning remote find a button you dont use and teach it the sleep button from your OEM remote.
