SOURCE: How to use my Zenith VRB4215 VCR with my new LG

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

Good day!!!!


That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

check for bad capacitor in the power supply board and then check shorted component parts at the sustain board.
