Samsung plasma pn50B550t2f wont turn on

(1/3) > >>

rickmav:
Mine just wont turn on,I got no blinking light,sound...just dead, and after watching video on U-tube;it seem that most the time it's a capacitor that blew up or some real cheap part.

so any one here can guide me on what to check or test first?

so far I check the power cord all the way to the power board by doing
a continuity test.
then see pic below;



#1 seem to be the one that break but if I compare it to a new one;
on the 2uf scale the new one read .063 and the one on the board read .069,should I still change it?

#2 is those 3 cap I decide to test,those 3 cap are 450V and 150uf and on the 200uf scale they all read 1 (this was done with cap still on the board),they should read 150uf +- 10% no????

#3 well I was just wondering about this one

or should I check other stuff?

thanks for any help.

And after checking the fuses?????

Turnip:
Hi Rickmav,

As Tony says - first check the fuses, esp as it's totally dead. If they're OK need to move on to the S/by power supply that feeds the main board to turn the set on.

Note the P/S Caps look OK, so it's getting complex, so you need a schematic and experience if you're really serious about a mend.

Good luck, not met one yet - Chris.

rickmav:
thanks for the reply

and yes I did check those 2 fuse,also the fuse on the X,Y board,I also check the power cord all the way to
the power board (near the fuse).

those 3 caps(#2 on pic) does visually look good but should I get a reading on my capacitance tester?

also a test I made,with the TV plug in and I touch the "touch pad button" in front bottom right;I can ear
a faint "tick" near the board where all the outside plugin are (cable/speaker/usb....) witch is way on the opposite  side,could be just static and not related?

a test I would like to make;up to where they should be power when the TV is plugin and turn off? and can this be tested safely?
