My bad, It's the connector to the right and slightly above in the pic. Epoxy on the wies but it might still unplug.

yes thats that i thought/saw in one of your first pictures you had posted earlier in the thread.

Re: 42"Fluid plasma tv Mod#(Samsung)pn50b550t2f

ok unpluged the cable in the pic, jumped terminals 3&4 on the test terminals and plugged in power,no pic's. It used to turn on with the remote but now nothing, blue power light is on. Maybe wrong cable??
I think I may have to start over. :-(
[I] wish I could find a place where they are test my mod. and used terminolgy I can understand, :-)

this thread looks the same set as yours are you sure you have the correct pins 3 and 4?

Re: 42"Fluid plasma tv Mod#(Samsung)pn50b550t2f

my board is different from any thing I've seen, I guess because the tv ( a fluid) made for radio shack. The samsung logic board # is LJ41-05078A screwed down underneathwhat I think is the t-con.

Re: 42"Fluid plasma tv Mod#(Samsung)pn50b550t2f

this looks like your board ?

so you have removed the lvds cable top right and used a jumper across the top two pins on the test connector and you get nothing on the screen ? all other ribbon cables etc connected still?

Re: 42"Fluid plasma tv Mod#(Samsung)pn50b550t2f

Thats pretty much the same but the 2 left hand pins are labeled 3 and 4 and thats where I put a jumper from a H/D. Screen still black.

Re: 42"Fluid plasma tv Mod#(Samsung)pn50b550t2f

maybe reece etc has some more tests/ideas you can do/run as im not sure what the next stage of fault finding is now as in which board to test next.

Re: 42"Fluid plasma tv Mod#(Samsung)pn50b550t2f

Hooray! I remembered reece saying all cables need to reconnected and I still had the 1 with 1and4 jumped,hokked it back up and voila test patterns but because I have to have the stand off to get at the boards it's laying face down and can only see the changing colors on the bottom edge. SOOOO, where do I go from here.lol. Btw the remote will turn it on but not off.

Told ya, sometimes you have to sort it yourself. You dont understand how hard and bloody frustrating it is explaining it lol right replace the mainboard and your Tv will work

Re: 42"Fluid plasma tv Mod#(Samsung)pn50b550t2f

um......are we sure that a europian mainboard works in a canadian tv?
As in pal to what ever we have ntps or something,and doesnt the uk one have those scart ports?

[vinceroger69]

Re: 42"Fluid plasma tv Mod#(Samsung)pn50b550t2f

Glad you have managed to narrow down the fault in post 47 i also did mention about having all the other cable re connected i would also check the main board (the one with hdmi ports on etc) from the uk will work in your country as you may not be able to use the tuner etc.

Re: 42"Fluid plasma tv Mod#(Samsung)pn50b550t2f

seller claims OK. Thanks for the heads up. Btw. tuners on separate board.

Re: 42"Fluid plasma tv Mod#(Samsung)pn50b550t2f

have you got a link to the board you have ordered? ive just looked at the picture you marked with a blue circle (post 36) the tuner looks like its soldered to it?

In post 39 I explained that the 1 circled was wrong, it's the 1 a little above and to the right.

Re: 42"Fluid plasma tv Mod#(Samsung)pn50b550t2f

i wasnt on about the circle more the tuner looks soldered to that board is that the board you have now ordered to swop?
