Samsung 24" power supply BN44-00195A first stage voltage?

Re: Samsung 24" power supply BN44-00195A first stage voltage?

First thing I would do for sure is to remove those brown/yellow glue from the board, they are conductive when it gets old. I see the blacken section on one part already. It will also eat away copper traces and component leads.
I see that burnt mark where the jumper is, and that is due to conductive glue in that hugh voltage and high switching frequency area.

Thank you!
just that it was my problem.
I cleaned up the glue and the monitor is working.

Great job got it fixed by just removing the glue before major damage happens.

What do I use to clean off the glue??? My monitor blew out too and this is my first time =\

Hi, I had a jumper blow j840 as well as the fuse, my psb is BN44-00214A, the semantic looks close to the BN44-00195A, I am going to clean the glue off tonight when I get home, I could use some tips as to how to clean the glue off.

Bn44-00214a SCH. I trim the glue down with cutting tool then use Alcohol to soften it for easy removal.

it was the glue! I removed the glue around the small cap next to the blown jumper and the leg of the cap was gone as well, 10 minutes of soldering and all is working well, I got this TV for free, and with the help I received here I now have my first flat screen!, thank you all so much

Great job, The glue becomes corrosive and will eat up the metal.

Hey everyone. Kinda a noob at this, but it seems this is the exact same problem I'm having. http://postimg.org/image/5m4zlh9g7/
There is a pic. I've blown thru 2 power supplies and have another in the mail. (Thankfully a free return) is this the same problem? Should I remove the glue when the new one comes in?

Re: Samsung 24" power supply BN44-00195A first stage voltage?

Hi. Think I'm having the same problem as you with the power supply. Could you take a look at my pic in your forum?

Re: Samsung 24" power supply BN44-00195A first stage voltage?

That is bad glue, it is in the high voltage section, must be removed, you should remove all the glue before the damages occur.

Re: Samsung 24" power supply BN44-00195A first stage voltage?

Thanks a ton. Both power supplies look just like this one. With my new one on the way, maybe I can repair the old one just in case.

New power supply arrives tomorrow. Hope this works

Re: Samsung 24" power supply BN44-00195A first stage voltage?

Voila! Success! It worked!

Glad to hear.

Re: Samsung 24" power supply BN44-00195A first stage voltage?

I checked the ICP801S and it really might be shorted. I think it would be better to replace the parts of the PFC:

ICP801S - FAN7530 ? (bad to read)
QP801S - FCPF11N60
DP802S - F10UP60S
QM802 - FQPF9N50C
QM803 - FQPF9N50C

Is it right?

I really hope that the psu will work after replacing these parts.

Otherwise - sh.. and thrown on the scrap heap.

Hey Ho,

Sorry i`ll write in German)))

Hi kleine Anfrage hat das mit dem Tausch der obigen Teile dein Problem gelöst ..... habe nämlich das selbe Problem (, wenn ja wo hast du die Ersatzteile bestellt falls noch zur Hand !!!

Danke im Voraus

r801 ..... ist bei mir leider komplett verbrannt kann die Ringe nicht genau erkennen isses nen 22 OHm

Danke im Voraus

Hi,

excuse my bad english. I also have a problem with my Samsung 245B Plus. The power supply board is the BN44-00195A.

The problem is Power LED on and often no picture. So I've already replaced the capacitors. Unfortunately, with no improvement. The next step i want to do is to remove the glue from the components. But it's not so easy. Do you have a hint how I can do it best?

The flashlight test I did and saw a picture. Furthermore, I have already measured from the power supply to the inverter 24V voltage. If a picture was there, i measured the 24V power. No picture, no voltage could measured there.

Which logical further proceed you would suggest. I am not a professional, but dare me to test the voltages at the power supply outputs with a multimeter. Unfortunately, I do not know where to start or what I may like to test. I'm hoping for a some hints.

Hi - you will have to re think your pictures they only show a thumbnails.
Also they dont look very sharp but may be that is because they are thumbnails. Suggest you re-size the big ones to less than 2mb and add to
your post using EDIT - GO ADVANCED then MANAGE ATTACHMENTS.

Try just one or two and only post any that are in focus we need to be able to read the numbers on the board

Hi,
i can't edit my last post, so i do these new.

Here is also a new Link.

Much better - thanks - there is a monster thread on this see here:

https://www.badcaps.net/forum/showth...ight=resistors

First steps for you are to remove the glue - not easy as you have found.
try and soften with isopropyl alcohol and scrape away - various tools have been tried
pointy plastic blades made from toothbrush handles dentists toothpicks.
You just have to take it slow an careful.

Second step is to replace the 3 82ohm resistors they are in a goup just below the BIG cap in your picture.
