Panasonic su board

[tvtimmy]

I was taking the white connection off the sc to su boards. The connector came off with no force at all but stuck in the male end. It left all 4 pins closest to the center, and left 1 of 5 toward the edge of it. The 4 pads are gone as well as the outside grounds that hold ti to the board. Me question is where do the 5 pins trace to? Are they a common ground? I cant tell. Pics to come.

Hey tvtimmy...
looked at my 50s30 board from tv that I am still working at (very slow as the boat didn't come thru canadian logistics yet... :-( ).

Anyways, that connector has the four "board side" connections (towards the basic board layout) connected into the 2,4,6,8 pins in the connector). The 5 that you have "missing" connect into 1,3,5,7,9. One my board, 9 has a test pad towards the side... kind of where the "9" is printed on that track. The others pins are soldered to "short tracks" that don't appear to go anywhere that I could "measure" with a meter. I am thinking perhaps they were "anchor pins" ... in your case not anchoring too good ... :-)

I haven't removed those boards on my set as I am hoping to not disturb things too much cause I don't really know what I am doing... :-) and don't want to break / make things worse than they are.

Just rechecked things after re-reading and looking at your pictures. I was mistaken about pin 9... it goes to a "short track" also BUT it is NOT connected to the "test point pad" that mentioned earlier. So all those "odd pins" are nothing but anchor pins for the connector.... my "read".

Re: Panasonic su board

I have a couple of sets from the 50" that I can also check. Thanks for the heads up. Might get lucky with some gorrilla glue to hold it down. I got this 55st30 with a 14 blink. Guy who owned it said it had a 13 code and bought a new a board,didnt work. The power supply is bad. I checked the 5 fuses and one was open. Replaced it and BANG. Two others blew. Been checking things on and then off the board and cant find anything yet.
