Re: bn44-00514a PS component list?
I think you guys aren't getting what I'm still trying to figure out....
I need help determining the ESR of the caps I need to replace. For example if I were to replace a 100v 470uF 105 degree Celcius cap, I can search for those specific examples on the sites you guys have mentioned so far.
But there's an issue....
There's like 15 different version of caps with the same specs, except the differences are form factor, lead width, and ESR.
The ESR is important because it deals with internal plus external...

Re: bn44-00514a PS component list?
Hey I figured out what you're talking about now. Sweet thanks for the info. I'm not sure what spec sheet to look at, but the problem is that they do not offer caps rated at 100v, and I have a few like that....

Re: Samsung 58" Plasma TV (FPT5884X/XXA) keeps turning itself off + clicking
Please check out the attachments. Based on your pics I see a component that looks like it should be replaced. But the problem with bad transistors is that the capacitors, diods and resistors surrounding that transistor could also be bad.
Also, the other attachment is of your PS card, which you should replace those capacitors for good measure....

Re: Samsung 58" Plasma TV (FPT5884X/XXA) keeps turning itself off + clicking
I'm currently working on a similar issue with my own Samsung 60" plasma. What I will tell you is that your clicking sounds are not coming from relays, as there are no relays on the power supply boards. That clicking sound is the sound of capacitors charging and discharging rapidly due to a fault. Occasionally the clicking will also be associated with a transistor beginning to short out and arch.
I've replaced my power board on my TV twice now...the first time it failed it had similar...

Re: bn44-00514a PS component list?
Thank you for your help TVTimmy. But i've seen this list before and it doesn't give info about the individual components. What I'm looking for is the type of capacitor I need to buy. I can read the capacitance and voltage, as well as the temp, but there are other factors like ESR and Size that come into play that I cannot identify conventionally.
Also what i'd like to do is upgrade the caps to something more tolerable, for example a higher temp tolerance and higher voltage value (like from 100 to 125). There's plenty...

Re: bn44-00514a PS component list?
Well I give up. So far all the components look fine (no burns/discolorations/bulged caps). I tested every diode as well and they all seem to work.
What happens is when I watch TV the screen will go black and the set will turn off (red standby power light also shuts off briefly). Then the TV "clicks" back on (it doesn't make that noise normally). Everytime it did it, the click would get louder and louder. Eventually it was happening every couple minutes which is when I decided to turn off an unplug the TV for good till I could...

All the MOSFETS in question have this white rubbery glue-like silicone covering them. That stuff safe to remove? FYI it's not Heat Sink Grease.

bn44-00514a PS component list?
Hello,
I've been trying to find out how some of you are able to troubleshoot this particular card without a schematic or list of components and their locations? I need to repair mine, but I just wanted to replace all the electrolytic caps instead of screw around testing them...but then I noticed some other folks had issues with the MOSFETS shorting out.
So basically I just need to find out what the part numbers/specs are for these components and figure out if I can buy them locally (most likely at Fry's Electronics) or order them online.
Once again...

Re: New Members - please post your introductions here
Good Morning folks!
My name is Zach, and I'm an Aviation Electronics Technician for the Navy Reserves. I learned electronics troubleshooting through the Navy back in 2003, but have loosely kept up with it, including my soldering skills.
What brought me here is that I have a Samsung 60" 3D Plasma where a power supply board keeps going out. I recently replaced two boards which included the power supply board (it's the 2nd time it's been replaced now), but that was only 3 months ago and now I'm...
