My Sony STR-DE595 has a problem with some output channels. The front right is very dim and the rear left is just gone. What should I look for when opening the unit?

Hi snark63

Ypou have an intermittent problem that sounds to be heat related... the more work the amp does, the more heat generated by the output stages. This will be aggravating some poor solder joints that are cracked or dry. The unit needs some repair work done in these areas. If you have good experience with a soldering iron, the cure for this is to resolder the power stages of the unit, or any other solder joints that look to be failing.

I am more than happy to answer any other questions you may have about it, please get back to me here, or use the ASK function to go straight to me :) If you are still unsure, have problems, or we need to look at the situation more deeply, then before you give a rating for this advice, hit the ASK button Thanks for using FixYa, If you consider the advice I have given you as sound, a FixYa rating is a great reward for my efforts to help you. Cheers.

SOURCE: Sony STR-DE525 Left Rear channel not working

Most likely the amp for that channel is defective. If memory serves me correctly, there is a small amp chip mounted on the heatsink that is for both the left and right rear. I would change that first. It should have about 5-7 pins.

You need a 3.5mm mini jack coupler lead with phono plugs on end plug one end into your headphone output on ipod and phonos into your amp lead must be stereo

HI...
It will need tech service.
Check the Sony consumer site for who can do it.

SOURCE: The SONY STR DE595 goes

The protect thing is to do with an overload. It's more than likely that something in the main amp section has failed (perhaps a transistor on the big heat sink). The cause often speaker wiring touching together. You should look carefully at the this section for damage or burning. If you have a ohm meter you can test the transistors. If you place the probes on the terminals of each transistor and you get a responce like you had touch the probes together, you have located the source of the overload.
