Question about Samsung 43 PN43D450A2D Plasma TV
TV is Samsung PN43D450A2D and it turned off the other day and now wont turn on checked the power board no bad cap. and looking to see if anyone out there had any thoughts.
If caps there not puffed or leaking voltages in and out of the power board must be checked next (right at turn on of the set) to see which come up and or instantly go off....this is the place to begin.

poke it open, you'll find bloated capacitors at power supply board. biggest one, with power cord pluged into. replace with thesame value(s).
you good to go!
don't lie, next time! your set has been acting up fpr a while, before it quit. Remembering: few attempts to turn it on, then it works!

I doubt that moisture damaged the SMPS bd.
There are many circuit boards in your set and it will take a trained samsung tech to find the problem.

At this point it appears that your main board is probably bad. You most likely have a 5 volt scource going to the main board but its not powering up the set. The main board is part number BN94-00796A.
You might want to have a technician look at the TV to verify this as the issue before purchasing it. Please take a few moments to rate my answer. Thank you.

It was not your power board, Thought the same on several repairs.Found out it was the main board. The clicking was the tuner relay. I bet you own a SP-R4232. If so,The part you need is BN41-00574A. Also might be under BN94-00669A. Hard to find. Try Shop Jimmy/Or Encompass Parts. Not cheep tho. Hope this info helps.
Have a happy new year. Todd
