If you can use your oscilloscope, you can check the signals going to the anode/cathode drivers.
Page 10 of my Classic Notes If they are ok, then probably one of those IC's is faulty. If that area of the board has been reworked, maybe damage occurred. If you have spares, then swapping one IC at a time might reveal the problem. cheers Tony |
