VCR PLAYER PLAYS TAPE WITH INTERMITTENT STATIC EVERY 1/2 SECOND

get a VCR head cleaning tape as the heads may be dirty etc, apart from being outdated

You need to clean the video head. With these types of sets it's best to use a tape cleaning cassette. I should get a Scotch Head Cleaner Plus tape currently on sale on Amazon for around 4 pounds.

This is a problem of the mechanism vcr. loock into the vcr because may be the kids put some objet inside vcr. To check also all the vcr belts.

Ur VCR signal recorded free air throught an DTV converter box?Yes,this cause is normal,because VCR player have no digital tuner on the VCR player by itself,on it circuitries design.If recorded throught pay cable signal.Yes,than ur VCR video head player is dirty needed to be clean.Tries websites like Amazon.com,Ebay.com to buy a VCR video head cleaner vdeo tape.Just play it as normal as a video tape,when the video head clean,VCR will display clean head eject tape now.

As JSE suggested.
Also dump any very old tapes.
As you say some play perfectly, I suspect, from personal experience, that faulty ones are either very old, or if recorded on another machine, may be mismatched with your current player.

My guess would be dirt on the rollers inside the VCR. They sesnse a jam and ejct. Try a VCR cleaner (with cleaning fluid) and see if that helps.

try to find a multi-video selector swicth that the best you can do

VCR is set with blank tape..Bring up vcr control on TV with television set on Chanel #3, go to menu

Yes, Different sections can go bad.

Meanwhile the issue is with the tape player on vcr. Bet you that the rubber belt(s) that drive the transport have stretched and ............................

Most everyone I know had problems with the tv/vcr combo including myself. I'll never buy one again. I'm sorry you are having the same problem.
