 *  Turn the VCR power on by pushing the power button, and verify that it is on by watching the VCR display on the VDR, it will change and may brighten.  Find the CHANNEL buttons on the VCR and push one or the other to change channels.  Select the clearest TV station by changing stations and viewing them on the television.
 *  Select the 'Record' tape from the bench.  It is the tape that has doesn't have a square hole on the side of the tape.  Place the tape in the VCR.  Push the "REWIND" button.  When the tape stops rewinding, push the "REC" (record) button on the VCR.  The machine will make a whining noise and the VCR display will indicate that recording has begun. The VCR is now recording the television station show.  Wait 20 seconds then push the "STOP" Button.  Push the "REWIND" button to rewind. Push the "PLAY" button and the recorded television station show will play on the television.
-*  View the television video display for quality.  There should be no distortion, rainbow coloring, static, or lines.  These video defects may appear for one or two seconds after initially pushing the "PLAY" button.  If any of these defects continue longer, recycle the VCR.  Otherwise, the VCR has tested good, testing is complete, and theVCR can be sold in the Thrift Store.

-*  Remove any screws on the right and left side of the VCR case.  Turn the VCR so that the back is facing you.  Notice that the VCR metal housing cover overlaps the back of the VCR back on the sides and the top.  REmove any screws there holding the metal cover.  Remove the cover.  If the cover won't come loose, look for another screw holding it and remove the screw.

-*  Inside the VCR are three or four places to clean.  The first is the PLAY HEAD.  It is a shiny cylinder set at an angle that rotates freely, in the center of the VCR. AS you rotate the cylinder, notice that there is a groove or dark line with two to four little rectangle openings half way up the cylinder.  The 'play' heads are tucked into these gaps.  This is where the dirt accumulates.

 *  Get a Q-tip swab and put some cleaner from the red bottle on one end on the cotton.  Lightly brush the wet Q-tip across the open spaces on the cylinder to clean the 'play' heads in the same direction that the cylinder rotates.  DO NOT BRUSH UP AND DOWN.  Be sure and clean away any cotton fibers that get caught on the heads.
 *  Next, either to the right or left of the cylinder are one or two 'record' heads.  These are black or shiny metal with tiny wires coming out the back of them.  Take a new Q-tip, applying cleaner from the red bottle on one end, and lightly brush all stationary heads and then use the dry end of the Q-tip to dry the head face that was cleaned.

 *  Choose the 'play' tape, on the bench, and insert it into the VCR face.  The tape should automatically feed into the deck when you lightly push the tape into the VCR. If it doesn't feed in, recycle the VCR.  Remember to always save the tape.

 === Connecting the VCR for initial testing.===
-*  Find the Red and Yellow RCA plugs cable on the test bench.  This cable is connected to the television at the other end of the cable.  Look at the back of the VCR and plug the Yellow RCA plug into the "Video OUT" connector (it should have a yellow center) on the back of the VCR.  Look at the back of the VCR and plug the Red RCA plug into the "Audio OUT" connector(it should have a red or white center).

 ** '''NOTE: Some VCR's have two "Audio OUT" connectors, Left and Right (for stereo).  Either is suitable for pluging the red RCA connector into.'''
 *  Find the Coax Cable on the test bench.  It is a thick round black cable with a gold fitting on the end.  Look on the back of the VCR and plug the Coax plug into the UHF connector labeled "Antenna" or "Video IN" or "ANT".  This cable pulls in the Televison signal.

 *  Lastly, on the right is a thick black rubber cylinder.  It will probably have a brown tint to it.  This is the 'pinch roller'.  The brown tint is dirt from the VCR tape.  Take a wet Q-tip and begin rubbing the 'pinch roller' gently until the brown dirt is gone.  The 'pinch roller' moves freely so you can rotate it as you clean.  You will probably need to use several Q-tips with cleaning solution because they get dirty as you clean.  Then use a dry Q-tip to dry the pinch roller.
-*  Now replace the metal cover onto the VCR and put one or two scres in the back panel to secure it.  Plug the VCR into the power strip and reconnect the RED RCA plug to "AUDIO OUT" and the YELLOW RCA plug into the "VIDEO OUT".  Insert the 'play' tape and push the play button on the VCR.  Did the SNOW problem improve?  If not, recycle the VCR.  If the video display on the television is crisp and clear, go to the Record Feature Testing.
