Philips DVDR3460/75

[Amraks]

Hi Guys I am Working on a DVDR there is no standby light.
Started from the obvious first.
PSU Fuse = All Good
Bridge = All Good

Checked Voltages
1 12V_STBY = 13
2 GND_D
3 5_STBY = 5
4 3V3_STB = 3

1 VGN_STBY = 5
2 5N_STBY = 5
3 GND_A
4 IPFAIL = 5?
5 GND_A
6 12VA_STBY = 13

What could this be?

So far I have replaced these caps on the analogue board just on a hunch that these might be bad not sure if I should go ahead and replace the rest in this area.

IPFAIL"-signal from power-supply-unit to kill the audio outputs can be
killed

Re: Philips DVDR3460/75

Can you explain that in some more detail not understanding what you mean?

Re: Philips DVDR3460/75

I found what you meant

("D_IKLL"-line) or the "IPFAIL"-signal from power-supply-unit
(in this case it's the combination of "A_KILL" and "IPFAIL").
In addition to that the DAC [7001] and the cinch outputs can be
killed (muted) in case of "digital silence" by the circuit around
[7008], [7009] and [7010], when no audio data are available
(e.g. "D_DATA0"-line zero).
This function can be also activated via the "ION"-line (set to
high during any stand-by mode). To avoid signal distortions
(clipping) the mute transistors for cinch rear out [7415], [7416]
are decoupled via [7011].

I just guess its killed all all audio inputs as nothing is hooked up.

Just thought I would redo my voltages

1 VGN_STBY = -25.73v
2 5N_STBY = -5.305v
3 GND_A = -4mv
4 IPFAIL = 5.180v
5 GND_A = 7.1mv
6 12VA_STBY = 13.20v


Checked Voltages
1 12V_STBY = 13.19v
2 GND_D = -0.7mv
3 5_STBY = 5.182v
4 3V3_STB = 3.494v
5 GND_D = -0.6mv

Thoughts?
