I think the PSR-I425 was based off of the PSR-E403, so if you can't find a service manual for the PSR-I425 then you might try looking at the service manual for the PSR-E403 to see if it helps you. I was going to check for it on elektrotanya.com but that site seems to be down at the moment.

I do have service manual of e403 but one can’t really get any idea as the schematics as well as component list are very haisy , can’t read anything from it. If you have clear / visible copy of the same then pls give me the link. Thanks for ur response.

Even if anyone shares the picture of audio board where colour codes on the components mentioned are visible , will solve the problem. Thnx.
