I bought a Panasonic DMR-ES10 DVD player on eBay
for cheap, described as "will not power on". Of course I expected this to be a simple case of bad capacitors, but that does not appear to be the case. There are no capacitors on the power board or other (logic?) board which are bulging or leaking, or even have elevated tops. All caps visibly check out. The fuse also looks unbroken. The power board has a manufacturing date of April 2005 written on it.

All reports I've read of this device not powering on point to bad caps. I wish that were the case. Does anybody have any ideas as to what is wrong? I can blanket recap the entire power board, but if someone might have a more specific suggestion I'd appreciate it. If somebody needs more specific photos of anything, please let me know and I'll be glad to provide them.
I guess for all I know, this device could've suffered a lightning strike, let out the magic smoke, and I have purchased a paperweight.
