Re: Samsung LN52A550P3F - No Backlighting
The board from shopjimmy failed, but they refunded the cost right away with no issues. Great company and I would use them again, but they no longer carry the part. So now I am back to the original board.
When I turn on the TV, the red light turns off, the light below the screen turns on, and I have sound along with use of the remote. The back light does not come on at all. The board does not click, but makes a faint buzzing noise. I checked all the capacitors and none of them are buldged out. None of the board looks charred...

Re: Samsung LN52A550P3F - No Backlighting
I ordered the part from shopjimmy, and since September it has been running like a champ! I started to get green pixles a few days ago, removed the back and sprayed the pins in the cables. Problem went away! Thanks for the help!Leave a comment:

Re: Samsung LN52A550P3F - No Backlighting
So I took the reading on Inverter On/Off and didnt get anything. And when I tried to take the reading for PS on the TV wouldnt turn on. At this point is it a safe bet to just order that part at ShopJimmy? Any chance I could be ordering a part that isnt broken? Thanks for your help thus far by the way!Leave a comment:

Re: Samsung LN52A550P3F - No Backlighting
Cool thanks for the reference point. I had no idea what those were called. I disconnected the thin light grey cable at CNI805 and the TV turned on with no backlight, and then tried it with the thick darker grey cable and it didnt turn on at all.Leave a comment:

Re: Samsung LN52A550P3F - No Backlighting
I'm not really sure which grey cable that is, but I disconnected at pins 23 and 24 on the orange board that go to the green board on the right with all the lines in. When I did that the TV didnt turn on at all.Last edited by eaglecaper; 09-15-2013, 09:31 AM.Leave a comment:

Re: Samsung LN52A550P3F - No Backlighting
I do have sound and don't have the multimeter. I can try to find one, but is there any other way to tell?Leave a comment:

Re: Samsung LN52A550P3F - No Backlighting
I have a Samsung ln52a550p3f as well and I can see the picture but I cant get the backlight on. There is an orange board that the power supply plugs into, and the backlight inverters also plug into it. Do all 4 of those have to be replaced? Or should I replace the entire board?Leave a comment:
