If you still own this piece of crap player and it doesn't work (LOAD, CLOSE problem), I have some information for you.
To simplify things, there might be a... let's call it
a very small crack somewhere on the mainboard that is fixed by:
- unscrewing the mainboard from the chassis (try one screw at a time and turn the player on to test if it still fails, you might get lucky, the mainboard might have been under strain and even removing one or two could fix the issue, but be careful not to kill yourself, this thing runs on electricity...)
- unscrewing the mainboard and then putting it in the freezer for about five minutes (this is a very bad idea if you live in a humid climate, condensation will kill the PCB, water and electricity don't mix, so again, be careful)
If your player starts to work normally just by messing with the PCB screws, then congratulations, you just might have a permanent fix, but if you need the freeze fix to make it work (very, very likely) then once the mainboard reaches room temperature and you power cycle the player, it will not turn on again (that is, until you freeze it once more). So once it initializes, never turn it off again and you should be fine
The thing that fails is responsible for initializing the player, so once that is "fixed", it works fine in room temperature. Hardly a practical solution, I know.
The more technically inclined might want to know that reballing the CPU might offer a permanent fix, but at this point it's just not worth it, although it could be a fun weekend project. You could also try the baking technique (yes, putting it in the oven, so that failed solder connections get fixed), but that has an anecdotal 1 in 3 chance of succeeding. Won't ruin the PCB if done correctly in any case, but again, not worth it at this point.
