TPV 715G6934-P01-000-002E Power Supply Module Damage in Philips 40PFH4009/88 Post-Storm

Hello. As in the subject of TV sets after a storm, a damaged power supply module with the symbol TPV 715G6934-P01-000-002E.
The Q901 K8A65D transistor and the U901 chip on which I read the symbol PF6003AS, EP002 under it, are damaged. My request for info what kind of layout it is, or maybe I misread it, because there is an indistinct inscription. Please help, info pdf or where can I buy. Thanks in advance.

Anything more? How many legs? what where?
In recent power supplies 715Gxxxx popular PF6200, PF7001, PF8200, PF7900.

The Q901 is a MOSFET-N transistor rated at 650V and 8A. The second is rather misplaced.

See if it's the same Link_ PSU 715G... for PS9700S
SMPS 715G5194-P01-W20-002S
IC5107 PF7900S SOP-8
IC9301 A6069H
*PF7700S also shown

ps
supplier Link_ US $27.40/10pcs
Or with H-Kong Link_ US $13/5pcs

Thanks for the express replies
I drew a diagram on my knee with this layout, it is smd 8 pin.
I probably missed some elements but the essence is drawn by the way
I tracked down a damaged smd C9110 capacitor, I don't know its value but it's a small problem. The symbol on the US is as I gave, I checked it with a microscope in the evening and it does not want to be different. I request information .

The PF7700 has a GND ground on pin.5
- pin.6 ISET, the connected resistor R8108 determines the current efficiency


The PF7900 has ground GND pin.6



They are for LED drivers
There is also PF7024 from this series, SOP-16 housing link_ scheme

And your PF6003AS (from this hand drawn drawing) is a system for power supplies on the hot side, i.e. you need to choose a replacement according to this table Link_HERE_AC_DC or Link_ HERE DC_DC
for this PF6003AS for now, no mom datasheet

looking so fast
pin.8Vcc, pin.5 control and ground have no equivalents.
Rework remains.

Thanks, processing is a last resort, a massacre, and such a simple converter.
In the LED power supply there is an 8-pin smd chip with the symbol PF7708AS.
But sneezes why invent so many different chips.
http://televid-sib.ru/index.php?topic=14291.0 I found a file with a similar scheme on such a forum, but unfortunately it doesn't want to register me there and I can't see anything. Help.

From some PF6003 power supply

Great thanks. Now where to buy? Or what's best to put in instead that wouldn't fire?

Tables and links provided > look in this topic of yours (30 Jul 2015 11:21), you have described the "in reptile" pins.

There is no replacement pin-pin fox! I would have already suggested.
You have to fiddle with replacing it with something else.
It's possible there's something mirrored or upside down... backwards.
You would have to look in both directions, actually in three - mirror up d ... too. ;)

I will add the TPN14.1 service manual with this power supply in the evening.

Hello again and thank you for your interest. I don't have that much experience
Among these new puzzles, Mr. Liska's hints would imply that I can choose
any jigsaw puzzle. As for the pins, making a spider with a different pin order is not a problem. I am interested in electrical parameters, what popular jigsaw could be inserted instead, I analyzed many schematic diagrams and most jigsaw puzzles have the same descriptions, but which one has how many grains of rice inside???. I do not like to let go of the subject, and in this case the converter is so clear and simple that it would be a sin not to do so.
P.S. Thanks for the service.

If you want a spider web, minimal, then enter the following layout in the fox link:
6 - VCC (because 8 is HV), 4 - GND, 5 - DRV, 2 - FB, additionally 7 - NC.
And analyze the patterns of the results.
As for the parameters of this "invention", which is a copy of something else, they are probably not sophisticated and standard values come into play, including probably the frequency in the range of 60-70kHz.

The problem is still not solved The TV is waiting in the ''freezer'' for a jigsaw or time to adjust something else. The client is patient for now, I don't know if the topic may not be closed? Appeal to everyone for help in purchasing the PF6003AS system. Thanks in advance.

So, looking at this description of the PF6003AHS pins, it is very similar to link_ncp1271

As for the original IC, it's probably only China.
The PSU 715G6405-P01-000-002E alone on ebay is about 70 euros + port?

Thanks for the hint. At the earliest opportunity, I will order NCP1271A and let you know about the effects.
Respect to Mr. Lisk and Mr. Mirex. Rhetorical question how Mr. Lisek got
such a resource of information, it seems to me that the day is too short to search and read and where else is the time for work and life ....?? Regards.

Hello after another break. I ordered the above-mentioned ncp1271a system, I changed the pin8 connection and changed the elements at the pin5 output, the power supply unfortunately started with a chirp and lowered output voltage, it should be 12v and 22v and I have 8.5v and 19v, after playing with the selection of resistances in the tl431 coupling, I got 12v, but the voltage 22v under load drops to 16v. I connected the power supply to the TV and the TV works
in standby voltage 10.2v and 22v in working mode 11.7v and 16v. Of course chirping (wrong frequency all the time). There is no description of the datasheet of the PF6003AHS system and these modifications are partisan. I'm not closing the topic yet, the client still gives time. In total, the power supply is only for two voltages, but low-budget repair limits the room for maneuver. Thanks for all the help and if the original layout appears, please let me know.

TV repaired at an authorized service. Thank you for your help.
