RCA VR652HF V.C.R. Problem please help...
By Chandler - usenet poster
I have this vcr for repair, the problem is that more than half of the upper
part of the image have snow and the bottom of the image is perfect. I tried
to adjust the guides with no success. The video heads look good but I ham
not shure. Before changing the video heads I would like to know if a
defective video head could cause that snow just in the upper part of the
image... Or what could cause this. I heard that it might be a bad feeder
tension but it doesn't look bad (Checked it without instruments) but it
doesn't feel to be that bad, i've seen worst.
Any ideas?
Thanks...

then it's not a tape path problem. If the tape path was off, the sound would
also be bad. Are the tape guides going all the way into the V stoppers?
Zenith & JVC used to have problems like this, it was a bad 3.3 Mfd smd cap
on the drum motor PCB. Maybe it's something like that. Maybe a head-amp
problem. I'm glad it's not me working on it! Good luck.

I heard it might be a capacitor in the capstan pcb and found that strange
but in the head motor pcb, it's very possible possible. So I have a new
question... I'm not an expert in smd, how do I know the value of the
capacitor, do I need the service manual or is there a way to it's value on
the part (there is nothing wrote on it, no numbers, no color bars...)
