Hi,
I hoped I might be able to fix this for my sister, but I'd like to try to narrow it down as much as I can before ordering anything.
It was supposedly taking multiple power button hits (remote or panel) to get it to boot, then eventually stopped coming on at all. The front LED will go from red to blue with no other sign of life. I've now verified that, by sitting there turning it on and off a bunch of times and have seen it boot maybe three, so it's not totally dead yet.
Does this behavior for that model sound familiar to anyone or does anyone know which components or board might be responsible for it? The supply caps still look to be in good shape and the couple I poked at didn't seem terribly high on ESR, but I can pull a board and get some more thorough checks if it would help. The main supply voltages seemed OK, even while in the "dead" state, with the 24V maybe being a volt or so higher.
Much thanks!
