Acetronics thanks, I tried both things grounding the MCLRE pin while powering it up with battery instead of adopter supply. It didn't work, so I think the chip must be faulty. Whether on external...

Mack: Yes i am using Proton, haven't done any change in the circuit yet but seems I might be able to run it on external oscillator by adjusting capacitors on OSC1 & OSC2 ports. Just realized that the...

Hello again: Here is an update on this strange chip. I placed the 1000 uF Capacitor on the input side of the 5V regulator as it was not letting the ICSP and placed 0.1 uf ceramic directly on the VSS...

Thanks Mack, MCLR is connected to VDD through a 10K resistor and also grounded with a bypass ceramic capacitor of 0.1uf. I also placed a big 1000 uf capacitor between ground and 5V line but...
Problem with PIC 16F819
Hi, I have this terrible problem with PIC 16F819, it does not starts up with external or internal oscillators if the supply voltage is 5V regulated. However if I decrease the VDD to 3.4 it starts...
