how bout that picture of the whole back, we don't have the tv on our bench so we can't see it.

Re: philips 65PUS6162/05 dead no sby led

the voltage on ps__on when mains connected (no sby lit) is 3v
pressing the remote or toggle switch at rear of tv does not change this voltage

because of the design of the psu ,the main board has to be fed 12v to enable any
of the important supplies to be produced
my attempt to force on the psu i used a link from the good 3,3v supply on the main board
and fed it to: ps_on
dim and
on/off
this produced no backlight voltage
earlier before any posting on the forum i checked all caps with esr meter and for good measure replaced a few that were not 100% cap value
i also confirmed the vcc1 and vcc2 voltages were good at approx 12v and that the backlight cct or LLC as philips like to call it revealed no s/c or suspect components

perhaps ,(as philips like to be different )the ps_on has to go low to turn on psu not high as i first thaught?

standby seems a little low, maybe unhook cable from powerboard to mainboard, recheck standby voltage with it off, if it stays the same maybe check that cap right by the connector, D9100, D9102 and the transistor right there by it on the heatsink, can you post a picture of the whole back, as to see how everything is connected?

PS_on is 3v in standby or power on?

sorry here are the pics
the cct is from 65pus 6162/12 version not 65pus6162/05
i dont know if theres any difference

hi to all,
following on from earlier post ref:no boosted pcf voltage
i managed to get a LD7591T pcf boost ic
i now have 385v boosted volts.
the psu produces 12v ok ,
(and bear in mind the 5v and 3,3v supplies are produced by the main board not as shown on the psu board markings.)
now, the tv has no sby led lit ,no backlight voltages
my thaughts were that ths processor could be faulty,but i wanted to completely eliminate the psu first
i checked all the supplies on the main board 1,5v,3,3v,5v, they are all ok,

the psu voltages:
dim 0v ,
on/off 0v ,
ps-on 3v
i fed 3.3v from main board to:
dim,
on/off
and ps-on
but still no backlight voltage
any ideas as to why psu wont give out b/l supply volts?
am i correctly trying to run psu ,or am i missing something?
