Re: Samsung Plazma Blues Model PN59D550C1F

Sorry I have not been on lately, wife is having some major health issues, tv has to put on the back burner for now.

Re: Samsung Plazma Blues Model PN59D550C1F

I replaced the 3 caps, and nothing has changed, the TV works great for a while, then randomly just shuts down suddenly. it will not restart until you unplug the set and plug it back in. It has gone for a week with no issues, to shutting down after a few hours. It is not consistent. I do not know if a short video can be uploaded, I will try to video the TV working and after it shuts down.

Re: Samsung Plazma Blues Model PN59D550C1F

sorry about the writing, force of habit. not sure why the tv shuts down, will only turn back on, if you do a hard restart ( unplug for a few minutes and plug it back in ). all the connections are clean and tight. I understand that the LED is supposed to blink when you press the remote, this blinking is extremely rapid not as normal. I have read that the main cause is a bad Y-sus board or main power board. I have replaced the boards and the same thing happens. How do you post pictures. I have clicked on insert image, cannot figure out how...

Re: Samsung Plazma Blues Model PN59D550C1F

Sorry For So Many Posts, I Am New At This.

I Have Some Experience Checking And Replacing Some Components, All The Capacitors Appear To Be In Good Working Condition, Resistors And Diodes On The Main Power Board Check Out Good.

Thanks In Advance, Duane.

I Am Looking For Some Direction, Or Suggestions On Where I Should Focus My Attention. I Have A 59 Inch Samsung Plazma Tv. The Tv Was Working Decently, Maybe Once In A Blue Moon, I Had To Unplug And Plug It Back In, As The Tv Would Just Shut Down And The Standby LED Light Would Come On And Stay On. If You Tried To Turn The Set Back On, The LED Standby Light Would Blink Rapidly Until You Released The Remote Button. Too Fast For Flash Codes. Once Plugged Back In, The Set Would Work Fine, Sometimes For Months. I Took The Back Off Of It, As The Was Some Distorted Pixels On The Right Side About 1/2...
