Thanks Ian,
the controllers has arrived (the second one) and the clock is running great, while it had the down time I did replace the 7805 with a murata buck converter (oki-78sr-5/1.5-W36-C), as suggested in another post by TY,
although a different spec one, works great 4.95v output and runs at 30°C

Cheers Mark

hello!
I started to reconstruct the PCB and now i am at the stage of connecting the RTC module and tick leds. I have 2 tick leds connected in series, the RTC module have the red light on but the tick leds does not comes on....the RTC module what does exactly? have any influence on the clock or tick leds? or just keeps the time when power is off

Solved...to easy to thing of....the RTC Module was the problem...somehow after the test mode the RTC was not communicating with the main PCB and was shutting off the tubes

Do you need a new RTC module? I can send you one if you need it.

Was this the problem causing the tube blanking?
