Hello,
i want to repair an Onkyo TX-NR809 receiver.
symptoms:
on power on, display appears and i hear one click. enue functions is given.
- no hdmi output
- audio output not tested, but i think it is not there
- usb sticks are not recognized
if i read out the chips with display+standby button + tone+
both dts show only ????
chip is D830K013BZKB4
things i have done:
- reflow of the dts chip without taking off and reballing
- changed the aluminium caps without the big one with 25v because i dont have a spare part here
measured some voltages:
die 1,1V - 1,8V - 3,3V and 5,2V are available
usb port is dead
the usb power chip gets the 5.2V but no voltage on the enable pin
i connected via serial to the hdmi board and get the following.
las message is starting kernel and then nothing happens.
maybe there is a nand problem ? oder its the dts chip or both ?
or is there another problem which stops the booting process
