TA-F444ESII Hi I'm after any info regarding this model as I have recently purchased this amp not working. The problem is it is going into protection after around a minute 30 seconds. It does have an LED lit on the right channel but not lit on the left. Now should both LEDS be lit up or should they both be out? I am aware of resistors going out of spec and have ordered them. Any pointers would be greatly appreciated THANKS IN ADVANCE!
First replace all the fuse resistors, this is a prerequisite, then you will see if the behavior of the LEDs changes
Are you aware that this is an extremely complex amp?
On the SM you have measurement points with values in Volt, you just have to take the readings

Thanks for your response. Yes I am aware and all but a few fusible resistors are out of spec. I have changed C516 AND C518 10v Caps and the unit is now coming out of protection and so far running ok. I have ordered replacement resistors and will update once fitted with the outcome. There still is one led not lighting.
the pdf document that I uploaded is the page containing the part of the diagram concerning the famous LEDs.
