Help! Something missed

[Mike9012]

Hi everyone,I have bought a famicom (HVC002 on the cover)weeks ago.
When I was  AV modding,I discovered something like capacitors or resistors lost.
I hope someone good to tell me what they are and the Exact  value of them(Are they important?),
so I can buy them to replace.Have a good day guys!
Here are the photos for comparing

The capacitor on the bottom of the photo appears to be a 330pF ceramic caoacitor and the resistor appears to be 1.2K Ohms.  I can't read the capacitor near the resistor, but it appears to be less than 100pF (68pF?).  I do not believe the precise characteristics of the diode are critical.

Thanks for your help! You are so great!
Will Anyone with rich experience identify the diode?

I dont understand your question, these added components are on older board revisions like HVC CPU 03. Newer boards were redesigned and built without them. I have such board (03) and I can check them out for you. What do you mean by "lost"?

I don't know why it disappeared,even don't know the function itself.
But I remember something on the back it should be,so google and find
Help here.Your help is appreciated.
