Where is the fuse located on my onkyo tx-sv434

SOURCE: Onkyo TX-SV434 "Protect" light

The protect mode is a built in safety message, indicating that theres a fault somewhere with-in the unit, and it wont let the unit come on fully or more damage will occour. This unit is a solid state device, and you should not attempt to use it or open it or try any self repair as it will cause more damage. If this unit is more then a few years old , it might just be the time to start looking around at all the back to school sales on electronics, as to have this unit serviced will cost an estimate fee as well as parts and labor. If you want to invest a few bucks into this machince , then go for it, but its most likly will cost 1/2 or more then the cost of the entire unit did when it was new to have it repaired. It is up to you. Good Luck

SOURCE: Onkyo TX-DS696. No right channel speaker sound

hello there 2 transistor 1 for the right channel and 1 for the left first thing 2 do is a visual check in good light check for any burn't part or any bulging capacitors if everythink looks ok then check underneath the board for dry joints if then you will need a mulitmeter to start testing components

Could you please confirm you have your system set to Speakers A and that the Surround Mode is set to Dolby Pro Logic?

Have you set the individual speaker volumes during the Test Mode?

Finally could you also please confirm the Model No for your DVR to confirm that this is giving the Dolby Pro Logic Output you require.
