Hi, Just completed construction. Took my time and checked every solder joint that was possible before powering up.
In the first Operate LCD display, CURR is blinking and the BUZZER is beeping and the FREQUENCY is displayed as 300kHz not 500kHz?
I've checked the pcb around Q8 and the tantalum capacitors as suggested in a previous post but cannot find any fault with those.
The xtal oscillator measures exactly 6.000Mhz on a frequency counter.
Can anyone advise me on this problems please?
Mni tnx
