Onkyo TX-SR577

[Adrian80]

Hi Peeps,

I have been trying to fix my broken reciever.

Its a Onkyo TX-SR577, its quite old, but it was working fine.

I think basically the centre channel has had it.

There are two very burnt looking transistors and i am trying to identify the correct parts.



I have no knowledge, and was hoping if someone could tell me if it looks like i am going to get the right parts or had any other tips.



1. TOSHIBA C5198 931

2 PHR MPR 2w R22K X2

There is clear evidence of the magic smoke come from certainly the TOSHIBA compnent and possibly the PHR MPR 2w R22K X2. However, that just might have burn marks because of the proximity.


I found a similar post: but it doesnt provide a good description of the parts.

Any help anyone can offer will be greatly recieved.

Do i need a special thermal grease or flux, or is any old thing ok?



Thanks
Adrian
