hi norman dual is one of the supermarket wonders no backup once the guarantee is up, but you say no playback picture does it play a prerecorded tape that is one that was NOT recorded on that vcr ,if so then it is not a playback fault but what is called no E-to- E ,therefor you check the tuner and IF circuit, can you do a recording from your dvd this does not require tuner and IFs if so your fault is in the tuner/IFs you can test these circuits without a diagram , if you need to know how to test please post and i will tell you . kind regards dave
