I'm a tech trying to repair (2) MP11DXs after a power surge. It blew primary on transformers. Canon is no help about getting parts. Found someone on net who will sell me schematics.

Any input.

Please don't send me automated responses and read my original question.

thanks,

keith

I would take it apart. Be sure to label parts, take pictures, so you can put it all back together. Some drink probably got split on it, so it sticks. Just clean it with a damp cloth and make sure it has stopped sticking before you put it back together.

Good luck.

Good luck.

Good thing you keep it unplugged, this is probably a bad capacitor on the logic board. Can be repaired at an electronics tech shop.

If you don't know about calculator electroncs, you don't have own means to repair it so take it to a repair technician, ask a diagnosis and evaluate if it's worth to repair your calculatoe or dispose of it.

You might need a different outlet for that now. Or unplug it and let it sit for a hour then try to plug it back in.

Well it is just a calculator, it cannot do all the possible integrals you might think of. You may try to help it a bit by using the usual techniques that you were taught to transform the integral into another it might be able to find: change of variables, integration by parts. You cannot let the success on your AB or BC exam depend solely on the calculator.

Even if it were available from TI, the LCD screen is not generally repairable and is either an integrated part of the mainboard (hardwired) or is attached to the mainboard by a ribbon cable. Either way, desoldering and then resoldering is tough even if you own the equipment to do this kind of work. Next option: check eBay for another used calculator.

Hi,

In the Y= equation editor you can enter two functions, and graph them both or calculate a table for both. However, the two functions will be evaluated at the same values of X.

Rather than trying to guess what is happening, I will show you how to get your two tables.

If you have used one the applications** Inequalz **or **Transform** it si probably still stuck in memory, and you must unload it from the RAM before recovering the usual calculator behavio(u)r

Press [2nd][GRAPH] (Table) to see your 2 tables y1 and y2 calculated at the same X.

Hope it helps.

Thank you for rating the solution.

If you have used one the applications

- Press the [APPS] button, find Inequalz or Transform, point to it and click [ENTER].
- You will be asked to Continue or Quit the application.
- Press the number corresponding to Quit (usually 2).
- Press [2nd][Y=] (STAT PLOT). Press [4:PlotsOff][ENTER]
- Calculator replies Done.

Hello,

If there is no special key reserved for that operation, you can use the raise to an arbitrary power key. This key is represented as [^] ( a caret or accent circonflexe) or [X to the y] or [Y to the x ]. I have just verified : it is primary key accessible directly.

If you want the cube of a number; 2 [^]3 =2x2x2=8.

In your algebra course they must have taught you that the roots of a number (square, cube, fourth, fifth, nth) are equivalents to raising that number to a fractionary power (a power whose exponent is a fraction of the form 1/2 ,1/3, 1/4, 1/5, 1/n etc.)

27[^] (1/3) = cube root of 23 = 3

Hope it helps.

I also have a Canon P23-DH 111 that is printing strange symbols. This has happened after an electrical storm.

I contacted Canon Support and they verified that the board inside has been corrupted by a power surge.

I now have a new Canon P23-DH V and I invested in a surge protector.

My grandaughter is playing with the old machine.

THAT PART OF THE SEGMENT IS BURNED OUT OR NON-FUNCTING ANYMORE, I DO NOT

KNOW IF ANYONE REPAIRS THAT TYPE OF EQUIPMENT ANYMORE, YOU CAN TRY TYPING IN THE MANIFACURES NAME AND CALL CUSTOMER SERVICE DEPARTMENT OR ASK FOR TECH SUPPORT DEPT.

BEST OF LUCK.

FIND ANOTHER ONE LIKE IT AND SWAP OUT THE PART, MAYBE GO ON EBAY EXPLAIN THE PROBLEM AND SEE IF ANYONE HAS ONE THE WILL PART WITH
