I have an RCA VR639HF purchased in 1998 or 99 and have tried to troubleshoot the problem I'm having. I only have a basic knowledge of components in a VCR after some googling. The following occurs when a tape is inserted: Tape is engaged in drum and drum is spinning. Tape is spun "backwards" into the supply reel by the capstan/pinch roller, but in most cases (not all however) does not travel around the drum but simply gathers inside the VCR and the VCR then decides to eject the tape. Sometimes it manages to collect the tape up again, and sometimes it does not.
In the other cases when the tape does not gather after inserting (manages to continue to the supply reel), the VCR only operates for about 2 seconds and things seem to tighten up (tension seems to increase) although that is observed only by a sound of the motors working harder. Then the tape is ejected.
Funny thing is that some tapes get further on in this proces than others. Some are ejected as soon as it's inserted, others are wound around the drum and tension is applied by tensioners and yet others get to the stage listed above. Any suggestions as to the cause of this and possible fix???
Thanks in advance

You need at least a basic knowledge of electronics to identify the failed part and replace it. If you don't have it then call a repairman - you can make the damage a lot worse if you mess with it blindly.
Take the tv aparts.The tv power supply board,that the board,have power a/c cord plug into it.That the power supply board,check component parts like capacitors,see if it leaking gases,these capacitors are dead.Capacitors they'll alway bulges up on it tops or puff up on it tops.Have tools like soldering iron and solders?Know basic electronic and soldering?Replaced these dead capacitors will get power to ur tv back.Or tries websites like Shopjkimmy.com to buy a whole refurbish power supply board for the replacement.
There may be a number of problems that are causing your HD issues. They may exist in your TV, or in the box you use to tune your channels. Contact your cable or satellite provider and ask them to change out your box. If the condition still surfaces, then you need to have your TV checked. The component and HDMI jacks are both connected to the same electronics. This is why they are exhibiting the same problem.
The color-coding used for the RCA connectors is nearly universal:
composite video - yellow
audio - red (right channel) and white (left channel)
component video - green (Y), blue (Pb) and red (Pr)
Also, these jacks are normally labeled in print as well, although it's sometimes hard to read the text on some equipment.
Match the connectors on your converter box to the corresponding connectors on the TV. If your converter box was one purchased with the $40 US Government coupon, it may not have the component video outputs. The only coupon-eligible boxes are the most basic models, and they sometimes have only RF (channel 3 or 4) and composite video outputs available.
This unit requires the rubber parts to be replaced. The loading sequence is not completing properly. The VCR will eject the tape when the sequence fails as a safety measure to prevent damage to either the VCR or the tape.
First, the R/Y/W connections are "composite" not "component" video. Component connections are green/blue/red and are a superior connection basically on the same level of quality as HDMI. If you have your TV and VCR connected this way, it will not be compatible with the RCA Y/R/W. I think you are confused as to what component and composite connections are. And, why would you want to connect a DVD player to anything at all other than your TV or a DVD burner? I don't get it.
If you are using R/W/Y, that is basic and the least sophisticated connection available. Further, if you connected this unit to your TV, then you would want to set its connections on "out", not "in", then plug them into your TV.
