NEC Turboexpress won't boot...

[MoBoRoS]

I recently bought a turboexpress from a seller that was selling it as working but apparently the capacitors were dead...
(I have a tendency in buying broken stuff...)
I replaced the crappy video and audio capacitors with new ones but the console now will not even boot... Should i try and remove every single capacitor and replace them with other ones? Or has a generic hardware failure occured?

I imagine if it won't boot at all now but it worked somewhat before it is something you did wrong. Maybe the caps you put in aren't the right type? Maybe one of the connections is poor? All I can suggest is checking your work and if you have to, undoing what you did to see if it restores it to its previous state isn't the worst idea.

The power connector in the Turbo Express is particularly bad. Are you using batteries or the AC adapter? Either way, my first instinct is to diagnose power issues at this point, rather than component failure.

I was using batteries... I am sure that the replaced capacitors are well placed and soldered. So i dont know wth is wrong. At first it was booting, but no sound/white image. and now its not even booting:/

I assume you followed the "audio fix" and "video fix" guides?

No offense to their creators, but they are half-assed attempts to fix what is a bigger problem.

Hawanja sent me his TurboExpress which was not working at all - I did both "fixes" and it did absolutely squat.


I went through, cataloged every capacitor on there and bought SMD replacements from Digikey, after replacing every electrolytic cap on the PCB, it worked beautifully.

Heres the parts list
