Sony Protection Mode (1 Viewer)

[Chris Dawley]

Hi,

I have a Sony STR-DE515 that I am working on. I found out that the transistors MP1620 and MN2488 were causing my protection mode. I replaced those transistors and still have protection mode. Do I need to replace the 180 ohm resistors and the .22 ohm resistor block? What about the little transistors in between the MP1620 and MN2488? I measured the values of the resistors and they seem to be fine. Is this receiver worth fixing?

Thanks,

Chris

Easy gauge is " how much for a good working one on Ebay"
If repair cost is greater than a working unit....no

Other considerations
Do you think upgrade fever will hit you soon?
New technologies that it is lacking

Gut reaction is NO. I owned a 815 back in the day, and though it was laden with a ton of nice features for the time, it's sound was less than impressive. I sold it for $100 back when it was only a few years old, and replaced it with a Marantz that was about the same price new. WOW, what a difference... That generation was only digital READY, so unless you are going to power some bookshelf speakers in a bedroom with it, I probably wouldn't bother unless you are looking for a project to entertanin yourself/learning.
