Hp cp3525dn no display

[songela]

This machine was previously displaying error 55.04.00. I tried to take off all the connector on the DC Controller and back again. I also didi the same to the memory DIMM.
On powering it ON again, the Display does only glow, but nothing is displayed. The warm-up Rotation can be heard and the indicators Ready, Data, and Attention light up once and goes and remain OFF.

I beg your help and suggestions please!

You can probably start by replacing the DC controller.

If the back light on the display is lit but there is no memory count it means it can't detect the memory DIMM usually. Try to do an engine test by hitting the button on the DC controller if it prints it's a formatter or DIMM issue.

Also check that you've plugged/not disturbed J303 on the
Inter connect board. Supplies power to the screen,etc.
I know cos I've forgotten to plug it back myself.
Printer spools up but you can't see anything.

Oops also J304! It's the one with the ferrite ring on the cable assembly.
