I get no picture, nothing when hooked up- blank screen. I tried unplugging- same. On many AVS threads I have read of these units failing. I probably burned about 400 DVDS on this unit that I bought in 2005 from Walmart for $330. It is not uncommon after about 2 years for this model to fail.. Not a hookup problem because my ES15 Panny worked perfectly with identical hookup on same TV and SAT box. I believe it is an HDD failure. I plan to call Pioneer in LA and see if they can provide me with a local repair facility- Pioneer has a big problem on these units as to failure- They are one of the best when they work but... I hope that my Pio 640 does not repeat this . I wonder if Pio sells an extended warranty on the Pio 640 as Panny does on theirs. I would buy it if the price is reasonable. An electronic unit that you pay this much for should NOT fail at 2 years. I may try to take it back to Walmart as I have my receipt. Satisfaction Guaranteed!
