How can I get my tape in my TV / VCR combi?

I have a Bush 14in TV/VCR Silver BTV180TSIL which has gone faulty. I cannot push a tape into the vcr as the machine rejects it. Basically I push the tape in so far but then the vcr resists and pushes the tape back out.

I don't want to start messing inside yet, or go to a shop for fixing as I'll probably get ripped off.

Please could someone diagnose the problem and a possible fixing solution.

Cheers,
Dave
