ATM Machine Complex Problem Solving: A Technical Experience.

Friends, I hope everyone is well. I usually share various experiences of our daily life with you. Yesterday I faced a very challenging situation in my work, which I will share with you today.

I went to the maintenance and repair of an NCR ATM machine. The first problem I saw when I went there was that there was no power or display coming to the machine's monitor. Although at first glance it seemed like a monitor problem, after a while I realized that the problem was deeper.

While working inside the machine, I suddenly noticed a slight sparking at a certain place. Sparking is very dangerous in electronic equipment, as it can cause a major short circuit or fire. I immediately became alert about the power source and carefully examined it to find the sparking place.

I saw that an important wiring harness wire inside had broken and was touching the body, creating this short circuit. That is why power was not reaching the monitor.

• First, I checked the electrical connection of the machine, thinking about safety.
• Then I cleaned the damaged wire thoroughly and reconnected it.
• So that the connection is strong and does not stick to the body in the future, I taped the area nicely using high-quality insulation tape.
• So that the cables are not messy, I arranged them properly and locked them.

After fixing the tapping and connection, I restarted the machine. The power came back to the monitor and the system started loading. Then I gave a CASH TEST command. As you can see in the picture, the TOP CASSETTE GOOD and SECOND CASSETTE GOOD messages were displayed on the screen. Finally, I successfully withdrew the money and confirmed that the machine is now fully operational and safe.

I experienced again in yesterday's work how important patience and close observation are in any technical work. A small torn wire can render the entire system useless. If it was not caught at the right time, it could have caused major damage to the machine.

For those of you who work in hardware or technical work, I would like to say to you, always maintain security and take even small errors seriously.
Thank you all for reading my blog. Your comments and support will encourage me to move forward further.

This was my arrangement for today. I hope you liked the pictures I took and the nature observations. Wishing everyone good health, I bid you farewell here today.
