Gear Door Retraction issue

[Vitek]

Hello to all the guys and gals on this forum!

Before anyone scolds me, I did do a search and found several threads with the same problem, but I have an additional symptom.

So here's what happens:

After selecting gear up/gear down, the landing gear extends/retracts. All gear doors stay open and close only after working the manual pump.
Now when several flights ago when this problem just started, it seemed as though the doors were trying to close by looking through the mirror.

I have checked the hydraulic levels and it is where it should be.

Any advice on what to look at is appreciated.
