Searching for Accurate BN4400622B Power Supply Schematic for Samsung TV

Question

I am looking for a power supply scheme from Samsung TV BN4400622B ps.schemat which is available on the net is not the one of this adapter

mirex · Answer

It is not and will not be there for a long time. However, there are some things on the systems working there as well. Or maybe you would be so nice and gave everyone the design of this power supply?

Kamra · Answer

And you do not know how it is with the power supply of LED strips, whether they are sequentially powered or parallel because half of the TV has no backlight

I am also looking for a scheme, Samsung UE40F6500SS TV.
BN44-00622B * L42X1Q DHS power supply, circuits such as fox mates, only ICM801CS is FSFR1800HSL and this one is torn apart, it needs a schematic with elements next to it.

File reported as dangerous, available exceptionally without logging in.

mirex · Answer

What does he say to you that he is dangerous? None of my watchmen have a problem with him.

Each file on archive. it is available without logging in, and not "exceptionally".

And anyway .... have something to fox. If he prefers foreign links, although we have two files BN44-00428, that's his thing.

Not only two, because FSFR1800 and FSR1700 are still BN44-00338, BN44-00339.

If you want to save it displays info that contains links to viruses and other programs.

kazikszach · Answer

I tried to determine the cause of the FSFR1800HSL system damage.
After desoldering this system I did not find any further short circuits, I decided to check the PFC voltage, I loaded it with a 1k? resistor and switched on the power supply, after clicking the relay the meter showed 310V for a fraction of second and the power fuse was blown, short circuit got MOS transistor in PFC, after disconnection and re-switching to the network, the balloon from the ICP801S SPC7011F system flew out, the voltage supplying it is 15V, which means correct.
I suspect that the PFC system somehow went crazy and gave too much voltage, which caused damage to the FSFR1800HSL system.

mirex · Answer

But what's that talking to you? Some AVG? Nothing included, I can not see anything quickly. Maybe your anti-virus for Chinese allergy? He treats this the same way from us? =========== \ You probably are right, Kazik, for the reasons for the FSFR damage.

Michał99 · Answer

Hello mirex. The one from the electrode is ok. It looks like the windows firewall is working.

kazikszach · Answer

The scheme BN44-00473A is very similar. Http://www.electronica-pt.com/esquema/lcd/bn44-00473a-ue40d5003-29726/
I installed the customer purchased from recovery due to the time, and with this damaged I will fight in my free time, because I have enough damage and the need to purchase proven parts.
