Question about Samsung SV5000W VHS VCR
The flat copper spring's lack of contact with the mechanism absolutely was the problem here! I soldered some copper braid on the spring and soldered the other end to a lug conveniently located on a bracket behind the right side of the drum.
Vodeo 99, you are right. This is a design flaw. And properly grounding the mechanism in this otherwise decent deck should rid you of the white flecks (that do resemble dropouts) in your picture!!

Clausiomas is correct it is caused by poor connection between flat copper leaf spring on pcb and edge of mechanism chassis at rear of chassis behind head drum assy, causing poor grounding and pb video noise. Sometimes simply flexing unit will change or temporarily fix. I solder a 4" wire with crimpon eyelet terminal on one end to leaf spring, and terminal under one chassis screw with a star lock washer to ensure ground.

The SV-7000W model has exactly the same problem (even tapping solve the problem temporarily) , but as I am not a natural english speaker I did not understood exactly you guys have done, and where. Can any good soul post a picture somewhere marking where the problem is ? I am getting mad with this - I am searching for the solution of this problem for over 3 years :-(
With the VCR cover off and looking at the round head drum, just to the rear below the grey chassis are two copper tabs sticking out. These supply the ground to the grey chassis and may not be making contact. If you remove the 9 screws securing the grey chassis you can lift the chassis enough to reach under the copper tabs and gently pry them up. Re-install the screws and the cover and the snow problem will go away.
Thank you very much, BigBlok502 ! I will try to do that asap !
Just bought a SV-5000W, and not surprisingly it has the same snow issue that many owners seem to experience. Off to try the copper tab solution... Thanks for posting, BigBlok502!

It is definately the bad ground contact. I soldered a wire from the copper ground springs to one of the chassis screws. I attached a wire O terminal to the other end of the wire, sanded the grey paint off around the screw hole (for good conductivity) , and attched the terminal between the screw and the chasis. NO MORE WHITE SPECKS! After dealing with this for years, you have solved the problem. I was almost going to buy a new unit, but now it works perfect.

Loose flat spring leaf between main board and mechanism
solder a wire or lift mecanism and bend the leaf spring.

I have had 2 of these units with the exact same problem out of the box. (hundreds of white flecks that flash across the screen)
It's not dirty heads or a loose wire. It's a design flaw with the unit. I do not know what a flat spring leaf is...Could you explain the above solution?

Some possibilities - Dirty video heads, but unlikely. Could be bad Connections / Cables. Also, could be due to electrical noise or loose connection / cold solder inside the VCR Video Circuits.

Have you tried cleaning the video head? This would be the place to start. You mentioned tapping on the rig will temporarily fix the problem, and this doesn't fit the dirty head diagnosis, but it is worth a try. Also check your connections to/from the VCR. You could also be seeing "snow" due a poor RF out connection, if this is the way it is hooked up.

This solved my video issue but when I tighten the chassis back in place I lose the audio. I slacken the screws and can get audio but video goes bad. Something shorting I guess when I tighten the screws but cant figure it out! Any clues?

I found this video on YouTube showing this exact fix:

Hi, by accident I found an easy way to fix that problem. Before I inserted a tape in the VCR I tightened the tape by drawing the sprockets with my fingers. Sometimes the problem come back after half an hour or so. Then I ejected the tape and do that procedure again. Please try it for yourself.

Yet another Samsung SV5000 with the same problem. Mine now has the cleanest heads of any VCR but it didn't solve the problem. Bending the copper strips at the back of the chassis behind the drum instantly cured the problem, at least temporarily. As soon as I get time I'll do a more permanent job. I was about to sling it in the garbage. Samsung, you **** for such junky workmanship.Thanks to everyone here for saving me the cost of a new VCR.

I have 4 of these units that I used for a one time duplication job then used once in a rare while to to a VHS to PAL conversion. The decks were bought new and none of them have more than 20 to 30 use though they were bought in 2004.
This week one of our clients ordered a series of 30 videos that we had produced for them and they wanted it in the PAL standard so that they could send it to their office in England. I confidently hooked up one of my nearly unused Samsung SV5000 decks and ended up with the sparkle or snow effect problem described by others here. My first response was that the head needed to be cleaned, so I cleaned it and the problem seemed to resolve for a second or two of tape. I tried dry cleaning, wet cleaning and take it apart cleaning. After retrieving the other two barely used decks from storage I found that the problem with the first Samsung SV5000 deck was also present in the other two. attempts to clean the heads on these two decks met with the same results as with the first deck.
I is beginning to be hard to believe that these units are not defective.
It may however just be in the playback portion of the head and not in the record head. I say this because when I record a tape in NTSC standard and then play in back on one of these decks there are the hundreds of annoying sparkles on the screen, but when I put the NTSC tape in another NTSC deck it plays back without any snow or sparkles. All tapes play back with sparkles in the Samsung units even if recorded on another tape. I hope that the PAL tapes will play back in another PAL deck, but I have no PAL deck to check them on than doesn't show the sparkles.
I have unpacked an SV-5000 after moving it (in its box). If I record a tape in NTSC on it and play it back, I see white flecks (dropouts) on the screen. If I take the same tape and play the recording back in my JVC HRD-565U (purchased in 1985!) , the image is free of dropouts. If I record a VHS tape in NTSC on the JVC and play it back, no dropouts. If I take that recording and play it in NTSC on the SV-5000, I see dropouts.
I have run a wet system cleaning casette three times. No change.
I have used the reset button on the SV-5000. No change.
I have used the undocumented "soft reset" procedure (eject the tape, push STOP and PAUSE together and hold for ten seconds. Shut off VCR for ten seconds. Power on, load and play tape. No change.
I have used the Cold Shutdown procedure: Power off VCR. Remove plug
from wall. Leave for several hours. Plug in, power up, Load and play tape. No change.
At this point I think:
a,) I need to have a technician perform a manual head cleaning.
b.) I need him or her to test the playback circuits.
I have exactly the same problem (lots of smal horizontal white stripes) but mine's is the SV-7000W model. Can anyone elaborate that solution #4 please? I did not understood that one too.
