Indeed!

[B][I]New[/I][/B] Main Board was purchased and it turned on without a hiccup. Part # [B]BN94-01797[COLOR="SeaGreen"]D[/COLOR][/B] was the [I]available[/I] replacement.

It's the [B]original Main Board[/B] in there with all the tweaks I did to it. I can't really do any quick tests anymore as the TV is now at the owner's place so he'll have to put up with it for now. Will ponder some more on this.Re: Samsung PN50A530S2F Plasma Clicking Transformer BS

Re: Samsung PN50A530S2F Plasma Clicking Transformer BS
Celebrated too soon.
From a cold start, the TV will show vertical noise in blue or green (see pic) and then turn itself off, then back on as if it's trying to fix itself. Around 3 or 4 tries is when a normal picture will come on.
I re-soldered the connections this time on the [B]LVDS[/B] & other connectors on the Main Board. Didn't help. I'm wondering if the heat I put to the Chip area was what turned this on?
I also updated the firmware from a usb thumb drive. [I]Oh well.[/I]...Last edited by Kridian; 05-29-2013, 06:08 PM.Leave a comment:

Re: Samsung PN50A530S2F Plasma Clicking Transformer BS
No but that sounds like a good idea. I just did the heat gun for a minute using aluminum tinfoil in a funnel-shape to keep other adjacent parts from getting the heat.
TV turned on normally this morning so I'm happy. [I]Have to cherish the small victories.[/I]

Re: Samsung PN50A530S2F Plasma Clicking Transformer BS
These two stickers were attached to the original Main Board. When doing a search with the bottom number ([B]BN97-02185A[/B]), it only directed me to boards with the top number ([B]BN94-01797B[/B]). I guess this is what I should be buying yes?
Here's a site that has one but no picture to confirm it. [I]Wonderful[/I]. Would you pull the trigger and purchase it? Says it's brand new.

Correct, and no lighting on the panel at all. I made a [URL="http://www.youtube.com/watch?v=AMuajxRMexs"][COLOR="Red"][COLOR="Blue"]video of it for what it's worth.[/COLOR][/COLOR][/URL]
Oh wow. That would be the death knell for this thing.
For the record, according to its little sticker, the [B][I]new[/I][/B] Main Board# is [B]BN97-01985R[/B]. The original one is [B]BN97-02185A[/B].Re: Samsung PN50A530S2F Plasma Clicking Transformer BS

Hmmm, the instructions on the [URL="https://www.badcaps.net/forum/showpost.php?p=318461&postcount=2"]test panel page[/URL] didn't say to unplug the Main Board power connector. Just the LVDS. (?)
I was instructed to put the resistors on the power connector leading to the [B]Control (Logic) Board[/B]. (?)
I didn't know exactly where all the testing was going. I guess seeing if the new Main Board was still the culprit.

Re: Samsung PN50A530S2F Plasma Clicking Transformer BS
The [B]newer one cannot pass the panel test[/B] at all. It also relay-clicks in faster intervals than the original one so I guess it's bad too? [I]Ugh[/I].
Here are the two Main Boards together. They look a little different but they share the same code number.

Reverse the resistors? I did shift them over to the right which effectively reversed them but not sure if that did anything.Re: Samsung PN50A530S2F Plasma Clicking Transformer BS

Re: Samsung PN50A530S2F Plasma Clicking Transformer BS
Oh, sorry about that. In post #25 above the only reason it was clicking was because I forgot to unplug the power connector to the Main Board.
Trying to do the panel test with the X/Y-main plugged in just now resulted in no relay clicking but the screen is black (not on).
Do I take off the resistors for this panel test? What was that for?Last edited by Kridian; 04-21-2013, 05:51 PM.Leave a comment:

Re: Samsung PN50A530S2F Plasma Clicking Transformer BS
Jumpers on, LVDS unplugged from the Control Board and failed to test – just did it's clicking.
I'm wondering if I should put the original Main Board back on and see if that will work? I take it we've eliminated that it was faulty?Leave a comment:

So during this relay clicking, I am going to test Va & Vs post voltages while the jumper is on pins 3 & 4 (light panel test) or off?
