Add me to the list of people having reliability problems with the Centronics ZAT 502 HD.
I've had mine for about 2 years, and used it a few times per month. Several months ago, it started not coming out of standby mode reliably -- I hit the power button, the standby light goes off briefly, the channel display shows zeroes briefly, but then it goes back to standby. Initially, if I tried to turn it on repeatedly, it would work after a few (or several) tries. But now it just absolutely won't come out of standby.
Any ideas on how I might revive it? Or is it destined for the recycling center?
Assuming I need to replace it, any recommendations on what I should replace it with?
