Question not clear
Find an old or blank tape that you know to be clean and just let it run for 15 min or a half hour. There is a fair chance that it will clean your heads all by itself by wiping the contaniment on to the tape and you won't have to open the unit or purchase a cleaning tape if this works. Added bonus, you are not running anything thru your machine that it is not designed to run. If this doesn't work then it may be time to open it up and clean manualy. Be careful when manual cleaning because those heads are very very delicate. Mark Dischler's remarks above are correct. DO NOT USE A COTTON SWAB! When you clean it like he said, use denatured alcohol and place the moist pad you are using on the drum in a position that has no head and hold it there while you rotate the heads to wipe across the pad. Don't move the pad at all. You risk breaking off the heads and then you are screwed. In fact, don't lift the pad after you have swipped the heads untill the pad is in an area of the drum without a head. The pad does not move during cleaning, only the drum. NEVER EVER WIPE UP AND DOWN. Use only gentle pressure on the pad also. Just enough to maintain contact during the drum rotation while cleaning. About the same pressure you might push on your eyeball if your eye lid were closed without too much discomfort. Good luck and be careful.
This happened to me once and it was as simple as the SCART lead was not in properly once I pushed the leads in properly it was fine
Hi,
When you say you have no picture, is the screen black or is it snowy? If you have a 4 head VCR, it sounds like one or two of the video heads are damaged, but I can't confirm that until I put it on my VCR analyzer. Since you say that you have a picture when you put your VCR in Forward or Re-wind, what is happening is that the AB head switcher has switched to a different set of heads, and those are not damaged, nor blocked with dirt. It could just simply be dirty heads, and if you can purchase a VCR head cleaner, it should clear it up. But sometimes, you have to clean them by hand and you have to use a special cleaning swab specially designed for VCR heads. If that doesn't clear it up, heads are damaged, provided there are no other problems.
Ken.
Sounds like you have dirty tape heads or a defective tape head.
Most modern appliances are disposable being uneconomical to repair. You can use a head cleaning tape if you can find one.
Since this is ancient technology that could be a challenge.
Even with a cleaning my guess VCR is junk.
I suggest upgrade to DVD.

I make no claim to being any kind of an expert techie but it sounds to me like there are one or more loose or badly worn parts inside your machine. If you haven't had a look at the innards, try that. Loose things can usually be re-secured and, sometimes, worn parts can be replaced.

the rotary head might need cleaning carefully with cotton bud and isopropyl alcohol. The top needs to come off. The heads are actually two very tiny slits attached to the rotating drum. They are delicate. Leave to dry five minutes before inserting tape. If this doesn't work it's a repair job.
Cotton bud is just about the worst thing for video head cleaning. Use a piece of lintless cloth, a handkerchief, or a piece of an old t-shirt with the alcohol. Place the wet cloth against the lower portion of the rotating head assembly. Rotate the head drum by hand, placing emphasis on the 2 video heads. As Andrew mentioned, let it dry for 5 minutes then insert tape. If at 1st you don't succeed, try again.
