Apex ADV-3800 Progressive-Scan DVD-VCR Combo
The product and the company are highly flawed
I bought the Apex ADV-3800 from Amazon because it seemed like a great price.  I had no problems with it at first. Then, a malfunction started.  I no longer got video output from the DVD player.  I could still view cable channels and VHS tapes fine.  But when I switched to DVD mode, the screen would go black; there wasn't even the generic-blue DVD screen.  If I inserted a DVD and pressed the buttons in the right order, I could get the DVD to play.  However, I only heard the audio (which came through flawlessly); the screen was still black.  I tried calling Apex's customer service number (both the California area code and the toll-free).  They were busy every single time.  Except for once.  The one time that it wasn't busy, I was on hold for over 3 hours before I gave up waiting.  (In that time, I went from #17 to #3 in the queue, according to the recorded voice.)  I also posted my problem on their website.  They promised a reply within 24 hours but none came after 5 days of waiting.  I even called one of the companies listed on the Apex website as a licensed repair company.  The company told me that they also have great difficulties with Apex, especially in getting hold of them on the phone.  Spend your money on a product supported by a company that will actually help you if anything goes wrong.  Avoid Apex.  I'd give them zero stars if I could.
