Hi guys,
sorry but its my week for asking questions...
Thought I'd fix the displays on the Meteor. I have fixed all but 1 display and are looking for some advice.
The problem is that the 1000's digit does not light up. I had the same problem with two other displays but fixed by replacing some 100K resistors and a dead tranny.
With this display, I've check and even swapped the two transistors and the 100K resistor for the 1000's digit. I've even put a CRO on the board and can see a waveform on the pins of the actual display tube (pins 24 & 26), it looks the same as on the 100's digit. Im thinking the actual glass display has a faulty digit but I haven't read about anybody complaining of this symptom before...
The attached photos are of the faulty display
So my question really is - do the glass displays drop digits sometimes and hence I need to find a replacement?
Or is there a way to try and get the glass display going?
