Will not run video - lights comes on and says "service"

Digital TV can use component video and stereo connections to record on analog VCR. Analog VCR needs DTV converter to record digital TV channels. VCR play back use AV channel on TV.

ok you did not give the correct model the model you gave is only a zenith remote

but

please refer to this picture: http://www.retrevo.com/r/375bh427/3/Connections+for+your+VCR#q=Zenith+VRB4215

Rather than use the method in the picture above you should use the audio L+R and video OUT on your VCR and connect these three to the color matching audio IN and video IN ports on your television. The colors are red, and white for audio and yellow for the video. If you do not own a cable like this simply pick one up at radio shack they will know exactly what you need. The pictured method will work also but the picture and sound quality will not be the best possible.

Remember you are sending data OUT from the VCR and IN to the TV

its the wheel bearings. they run about 70 a piece once you replace them the lights will shut off

It seems to me that you have only got one set of RCA Cablec between the TV and VCR ( from VCR Video out to TV Video In), as such the VCR only works in playback mode, you need a second set of RCA cables (from TV Video Out to VCR Video In) then select the appropriate input (Video) for the VCR. make sure to follow the colour coding on the RCA plug / socket arrangement

Sounds like the video heads are worn and time to replace them. You can try Asti Magnetics. The part number you are looking for is "378". Sells for $55 plus shipping. A bit cheaper but quality parts. I've dealt with them in the past. You can decide if the VCR is worth it to repair.

Try adjusting the tracking on your VCR. This symptom would typically be caused by a slight tracking error in your VCR or video heads that need to be cleaned. Your Zenith TV may be a little more sensitive to video synchronization problems than your other TV is.

If VCR tracking adjustments have no effect on the symptom, then the problem could be in the TV, but I'll need more details to assist you with troubleshooting. For example, how do you connect the VCR to the TV?

not sure what year this tv is, but I had some where the tuner was bad and would be stuck on video. The only way is replacing the tuner. Or you may want to try hooking up a vcr into the video audio jacks and run the channels from the vcr it may work yet.

could be a small belt thats keeping the draw from opening or a power supply problem Or maybe even a fault in the slider assy that has the laser on it as if it doesent return to the "home" postions nothing else will work. Good luck
