Im looking for the total combination for this nuber 13 20 31 36 41 45 permutations i think its called

Do you want combinations or permutations? They're different things. A combination of n items taken m at a time, sometimes written "nCm", selects m items from a group of n without regard to order. A permutation of n items taken m at a time, sometimes written "nPm", selects m items from a group of m with regard to order.

Given six numbers, there are six combinations of one number, 15 combinations of two numbers, 20 combinations of three numbers, 15 combinations of four numbers, six combinations of five numbers, and one combination of six numbers.

Given six numbers, there are six permutations of one number, 30 permutations of two numbers, 120 permutations of three numbers, 360 permutations of four numbers, 720 permutations of five numbers, and 720 permutations of six numbers.

Entered wrong code to many times will only show err and wont switch off how do i fix it

Most cars will allow you to re enter code after a fixed period of say 60 minutes. I know that Nissans for example allow you to do this. The Nissan book I last looked at when resetting a friends car after she had done just what you have done explains to wait 60 minutes and you will be able to reenter code. However the book does not explain that you must have the engine running for sixty minutes. I imagine every car shall be different though. But it wont hurt to give it a go to have the car engine running and read a book or something so it doesnt get stolen while you wait in it or near it.

It is also common for people to put codes in incorrectly by not reading the owners manual correctly. The Nissan in our case we had a code of 2365 for example. This does not mean for the Nissan to type in on the stereo pad 2365. It means again in the Nissans case press the number one button 2 times then press the number 2 button three times then press the number 3 button six times then press the number 4 button five times.

Bear in mind every vehicle is different, read your owners manual it should "in theory: tell you how to do this. Worst case scenario let your fingers do the walking and call you local car dealerships servicing centre and ask to talk to someone for advise on your particular make and model. They deal with these things all the time, That is exactly how we solved the Nissans problem of not allowing us to reenter the code with this pain in the neck ERR on the screen not clearing.

Tv is on but wont play

Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.

Error code DR

Pull the tech sheet out of the dryer ( behind the lower front access panal ). The lights flashing are trying to tell you a fault code.

A copy:

MODEL DIFFERENCES: • Better models have a digital readout display
• Good models do not have a digital readout display
READING ERROR CODES 1. Position cycle selector knob to the 3 O’clock position.
2. Press and hold the Select and Pause Cancel buttons simultaneously for six seconds.
3. Immediately after, press and hold the START and Pause Cancel buttons simultaneously for 4 seconds.
4. Rotate the cycle selector knob to the 2 O’clock position.
On better model dryers, the error code will appear in the digital display. On good models, the five indicator lights of
Drying, Cool Down, Wrinkle Rid, and Clean Lint Filter Spin will flash the number of times for the first digit of the code
and the START indicator light will flash the number of times for the second digit. Take separate counts of each indicator
light, then repeat to confirm in order to be accurate in identifying the proper error code. The code is obtained by counting
the number of times the lights flash. Example E24: The five indicator lights would flash twice indicating the 2 and the
START indicator light will flash four times indicating the 4. The five indicator lights and the START indicator light start
flashing at the same time. The control will pause for 2 seconds, then repeat the code.
Note: A letter appearing in the code stands for a number higher than nine.
A = 10 B = 11 C = 12 D = 13 E = 14 F = 15
Example Code E4A: the first digit would be 4 and the second digit would be 10. If this code would appear on a dryer in
the Good model line, the five indicator lights would blink four times and the START indicator light would blink ten times.
Troubleshoot problem by using chart below.
To move on to the next code, press the OPTIONS button. To clear code, press the Select button.
To exit this mode, simultaneously press and hold the Select and Pause Cancel buttons for six seconds.
