    TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible. Does it?

Having gone over five months without a response, I assume the suggested contrast adjustment solved the problem.

Will turn over but wont start cant hear the fuel pump


If it hasn't run in a couple years, I would use a "test light" and check for power at the plug-in for the fuel pump. If ther's no power I would run a wire from the battery straight to the fuel pump itself. If the pump doesn't turn on you will have to replace the pump. If this starts it. If this makes it work you could put a fuse in the wire and hook it under the hood to any wire that has power when you turn on the key.

If you are trying to get it running again after 2 years it might be a good idea to pick up a Haynes manual for the car. They're only about $20 and have a lot of useful help for the DIYer doing average repairs. Hope this helps.

I haven't used my calculator in some time. Now when I go to use it, it won't turn on. I've pressed on and clear and reset. Nothing. It is solared powered and its not like I just change the...


If it is solar powered and hasn't been used in some time, the battery may have died, permanently. If there is no battery to replace then it is broken forever. Sorry.When batteries are left without juice for a long period of time they die, and cannot be recharged.

Won;t power up at all. New batteries but I did not replace back up battery. should I? Tried the contrast fix. Son said he dropped it and it got kicked down hall at school. One year old. Any hope?


Hello,

If new batteries did not solve the problem, the next thing to check would be the battery terminal.

If the battery terminal is rusty, the battery power won't contact and the calculator won't turn on. So, use a flat small screw drive to scratch the battery terminal so that there would be contact.

If the above is not the problem, the next to check would be the wire connecting the battery terminal to the the calculator's main board. There is a wire between the battery terminal and the calculator board. When the battery is inserted, the power from the battery goes from the terminal to the board through this wire. There is a possibility that this wire is cut in-between or is loosing contact. In this case, you need to get a small screw driver and carefully disassemble the calculator in order to check the wire.

If the wire is intact, use a light brush to brush the calculator board as there might be dust on the board.

If non of the above helps, then it means the calculator is dead and needs a replacement.

Regards.

Nikon N65 Won't Turn On , With NEW Batteries . This Camera Is NEW ! Please Help ''/


Nikon hasn't manufactured the N65 is several years now, so if you bought it it was either misrepresented as new, or possible new-old-stock (a never sold/used item, that's been sitting on the shelf for a number of years). I'd be willing to venture you probably ran into a disreputable seller.

Either way, open the battery compartment and look for corrosion in the compartment. If that's present clean it off with the eraser of a pencil and try again. If that doesn't work, contact Nikon service with the warranty information in your package. If it's a new item, it'll still be warrantied since the warranty won't begin until it's sold to a consumer.

If, however you find that the camera was sold 10 years ago and no longer under warranty, you'll probably want to either find a local reputable shop, buy another camera if yours turns out to be too expensive to repair (impossible to tell until someone looks at it to determine the issue), or if you don't have a local shop I'd recommend KEH Camera in Atlanta, GA for mail-order/internet dealers. They've been in business many years and are very reputable.

Ti 83 black screen problem


i had the same problem. If you hit 2nd down 2nd down 2nd down and keep repeating untill the screen clears it should solve the problem. i tried the other solutions that tried clearing the memory and they didnt do anything but erase the equations i had previously put in it (great). But this should work.
