Re: philips 65PUS6162/05 dead no sby led

read my post above.. your PSU didnt give 18V_12V high on pins 3 4 5 6..
take yours PSU out on the table and run it as stand alone... from 12V with R2K !w JUMBER IT TO ps_on:: ps_oN WILL TAKE THE CURRENTS IT NEED 3.3V and it should produce other pins 18_12V high.. .

Be carfull.. you should know exactly the pins of AU_12V and PW_18V_12V on PSU socket

Re: philips 65PUS6162/05 dead no sby led

on the underside of usb2 socket there are 9 contacts
two rows CN112
5 and 4
to the right of the black internet connection CN107
theres no voltage on any of these pins
see jpg
pins 3-6 i dont see any change in 12v it measures 12,4v
where does the 18v come from?

Re: philips 65PUS6162/05 dead no sby led

BTW . let bring things in correct way.. this is yours Service manual.. on page 48. we can see the system power on the MB socket will be.

STB will be only 12V on pin 7 & 8 =AU 12V ( this remain 12V )
after the eeprom start script load will send the signal PS_ON from PIN 13.
then on PSU PFC go high and should produce 12V high 18V-12 inter MB socket on Pins 3/4/5/6 = PW_18V_12V.

PS_ON you said you have... so check the pins 3-6 on MB if they are high >12V. if not PSU problem. and this why no Panel VCC 12V on T-CON

Re: philips 65PUS6162/05 dead no sby led

the blue wire is where i took 3.3v to try to turn on the psu earlier

this is wrong way for test.. because this 3.3V will return back to MB via PS_ON wire while the TV in sleep hope the MB didnt toasted..
so tell us which voltage you have on the MB. u said optic had 5V so this mean USB could have too.. u measure on the top side..and remark it on your early photo so we can understand where are the fault at MB could be.

what is this blue wire ?? is this DIY TV LOL..

Re: philips 65PUS6162/05 dead no sby led

at this case need more test on MB. you wrote USB1 was 3.3V which are low... however Audio OPTIC had 5V normal.. i would do the following and consider on the optic if lit or USB 1 become high 5V
a- panel complete disconnect from T-CON ( by disconnect ribbon )
b- messure 12V on T-CON
c- remove WIFI module from TV. or bluetooth . check if USB1 come high 5V
d- check after warm parts after you turn on the tv on MB..

im sorry
i made a mistake earlier when i measured for voltage on the usb socket
there is no voltage .
i was measuring on the wifi socket
measuring voltages on the underside of the main board
i made a mistake

Re: philips 65PUS6162/05 dead no sby led

i will try what you said but :
audio optic has 5v but is NOT lit red
i have no 12v on tcon
i will remove ribbon and wifi and see if 3.3v on usb1 increases to 5v
all the chips on MB are cold
i will post reply

Re: philips 65PUS6162/05 dead no sby led

i downloaded thr file ,extracted and loaded to clean usb stick plugged into blue usb1 skt then applied mains waited 25 mins .

Re: philips 65PUS6162/05 dead no sby led

try heating that bga again, its the easiest test, then go with the firmware if no change.

thanks Diah
i will try downgrade as suggested

Re: philips 65PUS6162/05 dead no sby led

Your words suggested just getting some heat in to see if there was a BGA issue, 200c is about right but you turn on whilst it's still hot, the heat causing expansion, hopefully making a temporary connection with any cracked joints.

ok i now understand thanks for reply

is the loader you kindly posted the same for 17.9?

Re: philips 65PUS6162/05 dead no sby led

what temp would you recommend when attempting a reflow ?
and for how long approx?

Re: philips 65PUS6162/05 dead no sby led

interesting .ive never heard of half boot
the opto port is not lit but does have 5v on it
usb1(blue)has 3.3v on it
usb2 has no voltage on it

the first cct i found was tmp17,7 e ly which is similar
.but i later found the correct cct tmp 17.9 cct

Re: philips 65PUS6162/05 dead no sby led

from what i can see there are only 3 things that can control the psu state:
dim
ps/on
on/off
the remote reciever small pcb has 3.3v feed ok .
on one of the pins when remote button is pressed the voltage drops to 2.9v
this tells me that the remote reciever is ok

from yours confirmation above... and you have PS_on. then could be MB at half boot... did you messure any USB post had 5V? did the optical audio port lit red?
if one above are correct... i would suggust you to start with firmware downgrade
with upgrade_loader 17.june.2019

Re: philips 65PUS6162/05 dead no sby led

it's a mystery, guess one option is to get a powerboard from someone with a generous return policy, if it don't work then you probably won't be out much if you need to return it, maybe just a small fee plus shipping? I might try it with some of my crap, or might just switch to fishing.

hope you have better luck fishing than i do with repairs

Re: philips 65PUS6162/05 dead no sby led

powerboards can be a real bich, have failed on my last 2 board repair attempts.
