My Yamaha PSR 1445 is not turning on.
I thought this was a problem by the adapter and hence to confirm it i tried the battery mode of it and it still didn't start.
When i try to turn it on the start button is like the usual it goes down but nothing happens.
Anything i could do to fix this?

Are you sure about that model ID? I can't find "PSR-1445" on Yamaha's website.

Well, I don't see the service manual for the PSR-I455 on Elektrotanya.com, but there's one for the PSR-I425 and one for the PSR-E443:



I think the PSR-I455 is very similar to the PSR-E433, and the PSR-E443 was the followup to the PSR-E433. Likewise, the PSR-I425 was the predecessor to the PSR-I455. So I would look at those two manuals to see how similar they are with respect to the power on/off circuitry and parts. That might help you diagnose what might be causing the problem with the PSR-I455, or what parts might need to be replaced.
