Seee...

PS xxxx ?

Hi yeah but sir Diah says:
change
R6853 (100ohm) [can't find it]
C6826 (1uF 10V) [can't find it]
PS6800 (500mA) replace it with Zero Ohm R
Only the last one I find it... 🤷♀️🙄

I probably mixed up the component numbers with another power supply, replace the fuse and check again.

Understand I'll check if I have the fuse eventually il put the resistor and hopefully it's will start

I only see partial pictures and not well clear,.can you make some decent ones where i see also well the led driver part? post also under side.. the better is at open air, sun light is the better, 2000x2000 pixels.

Yes sir here you are those pictures,
unfortunately i only have this lower kind of resistance. Thanks

at yours PSU one No less
R6852 (100ohm)
C6824 (1uF 10V)

if R6852 read less than 100 ohm or more should be replace if not then replace only PS6800 with normal glass fuse for test if every things work fine you buy 0R SMD and put it in place

Sorry man maybe you mean this one ( R7850)right? Then I found this kind of fuse, can I replaced it definitely ? Thanks

This is a 500 mA self-recovery SMD fuse, you can install it for testing...

Ok, fuse installed. C6824 measure almost 2 uf, i don't have in stock the R6852 ( 100ohm) i don't have the mark R6852. Only R6850 i show you just before on picture.

if c didn't shorted go head turn on

Any power at all it's totally ded now

[Diah]

start ti check from wall socket to fuse on PSU this had nothings to do with yours work at cold area section

[Davi.p]

test Q6814 (TO220), R6850 (2W resistor)

Fuse is OK, both capacitor on the primary side i have 320v but standby 3v just disappeared ( before I have it , also sound i have it tv turn it on ) now notting , neither relè click on

test Q6814 (TO220), R6850 (2W resistor)

Tomorrow, now I will eat something and go straight to bed. Tomorrow after work I 18 pm will check . Se you thanks all

Remove the fuse and try to turn it on, this fuse does not work immediately and the protection may be triggered and the power supply goes into protection and the supply voltage disappears.

This is a more complex scheme than usual ones, like Sony habits, i can't read well from photos on a cellular, sorry, but i'm almost sure you'll find the 2 components burnt..
