Yes, if you tell me the model the board came from, I may be able to find out what resistor to use.

If you ordered it from Flattvparts, they would tell you what TV it came from.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Panasonic P50G20E
Tom I mounted one fan but again turns off
fan works but I can not measure the resistance of fan
update
this motor(fan) is brusless fan maybe that's why offLast edited by Stanislav; 02-01-2013, 02:03 PM.Comment

Re: Panasonic P50G20E
The yellow wire needs to stay low, I believe, on this set, a normal computer fan will pulse the yellow wire. Try disconnecting yellow and forcing it low with a 100~470 ohm resistor.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Panasonic P50G20E
the fan is not PC ,it is dvd fan and have two wires red and blacк
definitely not suitable for this boardComment

Re: Panasonic P50G20E
OK, you need to connect the unconnected terminal on connector to GND with 100~470 ohm to trick the board into thinking it has a fan and the fan is working well.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Panasonic P50G20E
You only connected two wires to that three pin connector right? On the pin you didn't connect, wire a 100 ohm to 470 ohm resistor to the ground wire, this should trick the TV into thinking the fan is always running.Please do not PM me with questions!

NO pin connector there is 2 pin not 3 but fan no resistance between two wiresComment

Re: Panasonic P50G20E
By its position, I'd say that's more likely to be an output for a subwoofer or speaker somewhere on the different version.
Any other similar connectors?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Panasonic P50G20E
No This is the only one who can look like a fan connectors.
if you enlarge the image to the right of the CPU see captionComment

Re: Panasonic P50G20E
Look, the LV4921 is definitely an audio amplifier, and that connector is for the fan. Panasonic fan use three pins, with wires of red, black and yellow. It MAY be that the signal is routed through the power supply, SC board or SS board - it is on some models.Please do not PM me with questions! Questions via PM will not be answered.

Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic... -
I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow
This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board

I have a Panasonic TC-P54VT25 that will power on and prime the display but there is no image at all.
The panel is primed as there is a slight glow from the entire panel. This means the problem should be logic related. The service manual also confirms this and recommends replacing the A or the D board.
I have tried to get the TV to display the test sequence but I have been unable to and I don't even know if this TV has a test sequence or not. I tried following tom66's instructions in post #3 on this thread https://www.badcaps.net/forum/showthread.php?t=26790. There was... -
Hi everyone!
I happened several times, in the search for help from the web, to consult this very interesting forum.
So I decided to sign up and I intend to participate actively by making available my knowledge and experience on the subject, I'm a new user but at the same time I'm old in the sense that I have 4 decades of experience in repairing and designing electronics but above all I'm a great passionate about the subject.
Having said that I come to the gist of my post on the forum as the title suggests.
For my passion for technology I'm now collecting several... -
My old plasma died when one night recently. When I got to it it was giving a 3.3v sos (3 blinks).
I chased my way through the PSU, and a board, with no results.
Replacing a few bulged caps in the PSU, I eventually got to the SC board that had piles of shorts, a quick cheap replacement from china and the tv powers up again, except
I only have the right half of the picture.
Left half is completely blank.
now the c3 board running this side of the screen has its 3.3 and 5v onto the buffer ic and its got the 60v, so that all seems good.
all the other voltage rails...09-24-2024, 04:39 AM
