[daniel1987]

hi my plasma tv started this morning and then after a few second it shuts down by itself and again start and so on it has no blown caps no cold soldering removed every board from the tv none has burn marks or any other marks.
I plugged off the ribbons from x,y boards did the pin test same thing shuts down by itself.
My psu is BN44-00206A w3.

Can you supply pictures of the circuit boards. Have you taken any voltage measurement?

Unfortunately I know little regarding Plasma TV however I believe they have the various voltage you should be able to measure written on labels at the top of the screen. VA, VS and some others.

I'm sure there are others that can help on you diagnose further.

So today i took the tv to a guy in my city ho does have a tv repair service and the fault was in the memory of the av board .
For thous who have problems like mine consider replacing the av board cheers

Samsung is known for a SMD=surface mounted capacitor to fail causing the powering off and on issues.So anybody that runs into this issue and doesn't wish to replace the main board pl check the caps.Also I've found that bad connections on the PSU can cause the same issue I have repaired a couple of Samsungs with this same issue. I can't remember what the value is of this cap is right this moment but when I do recall the info I will update this post.
