- All seven segment LED light having use 5v300mA regulated DC
so in this watch use 78L05 IC*3.(5V100mA power).
2 out of 3 IC is damage, so change this IC
Or
Replace LM7805 IC (5v & 0.5A to1A power) .
It is suitable for this.

I purchased Ajanta Digital clock model OLC 302 in March, 2020. So far it is working good. Everyday during night we put off the switch of the clock because the light, for better sleep, and switch on the set in the morning. But now after 10 months of service, when we put on the clock in the morning, it is swhwing reset mode on and showing a time of 11.59 pm and year 001 . Every time I reset it to correct time, it is working good during day time, and when I switch off during night and swtich on in the morning, I find it in RESET mode as above. I even changed the batteries also. But no use. Please adivice.

Light chaly Jane Ke baad battery se Nahi chalta Naya battery sell lagaya fir bhi
ye AC power se hi chalta hai, battery to Time ko thik rakhne k liye lga hota hai
CPU heat ho rha hai sir kaya change kare ki sahi ho jaye
Pahle CPU ki supply, break kre,
Phir 5volt regular pr 5v check kre,
यदि यहाँ पर 5v है तो CPU हो सकता है शार्ट हो ,
Cpu kaha se milega new help kar sakte hai please
