Hi Sir;

The display control board DSK consists of the

I was checking in DEEP, this matter with the CPC 1'04.

Please read carefully, and proceed according with Test board DSK, See the power for;+5+24vDC, in tolerance 0.7% up or down, 2) look for the power supply DNK2, according with the schematic diagrams 3) and measure in the ZID (Console Displaay) look for the schematic Diagrams 190'195vDC High Voltage, carefully. 4) Look very well for Ribbon and Flat cables. 5) Clean very well with contacts cleaner the pins, and look if there are some bent, or loose, and repair or replace it. 6) Reset the Processor in BEK/ZSK see my personal schematic diagrams for RESET The CPU or MicroProcesor+ example how to do it, for the Pins (search in GOOGLE for pins schematic, according with the CPU or Microprocessor that board if is; Intel or Motorola, or others.

The display control board DSK consists of the
display motherboard DGP and the EPROM
module EPM, x CPC' 1'04.

The computer of the display control board
analyzes the data serially transmitted by the
connected processor board (BEK/ZSK).

With this data and the data from the EPROM module EPM,
the image to be displayed is built up in the
graphics section of the display control board and
stored temporarily.

Via a parallel interface the data is transmitted to
the display power supply board DNK2. The
computer on the DSK processes the signals and
also makes them available to the graphics section
for image build-up.

Let me know, sincerely

 

Any update
????
