trying to figure out a plasma that wont start it just clicks from the relays its a samsung hp-r5052,
i replaced the LJ92-01045A X-Sustain / Z-Sustain Board for SAMSUNG HP-R5052 it was burned,
and dont see any capacitors blowned unless there bad but i dont see it whats next to check? i can replace it i have an iron, whats next to check ? i need help please

 

Do you have a schematic?

 

no i dont sorry, i just seen right now that on of them wire ribbons is cut

 

A photo or two might help then.

 

here it is a picture <a href="http://s272.photobucket.com/albums/jj189/PhotoMe4/?action=view&current=CIMG0557.jpg" target="_blank"><img src="http://i272.photobucket.com/albums/jj189/PhotoMe4/CIMG0557.jpg" border="0" alt="Photobucket"></a>

ill just tape it away from others. and try it

 

didnt work, still clicking the same 1 click the lad light lights up wait 5 sec then 2 clicking sounds i think it turns off the plasma, is it becouse i dont have nothing pluged in? like an antena or a ps3
just wanted to give a try
you dont think its something else or you think three broken mylar ribbons will not start up the screen

 

Disconnect the set from all power, and leave it sit for a couple days. Use a proper resistive capacitor discharging tool, and be sure the large caps in the set are neutralized.

Then.........Disconnect and brush all ribbon connectors gently with something on the order of a fiberglas scratch brush, or an abrasive eraser, then reconnect them.. Same goes for any board-to-board jumpers, check for bent pins, or and tarnish / dry corrosion.......check all boards thoroughly for burn spots, or blown fuses/components and repair any cold solder connections. You'll have to look close for connections that aren't real shiny, or have obvious looseness around component pins / leads.
Look also very closely at all IC chips, for any detritus, metallic or no, lodged between pins that could be mis-directing signals.

how do i discharge the capacitors, and fuses are good let me check more and how do i check cold solder?

when i unplug the x bord from dc-dc bord the relays click on right and you hear a beep sound like the tv startes black screen but i think now is the x bord is bad,,,

 

Did your repair solve the problem?

 

yes!!!!! you right and i finally got the set started without the X bord.
i figure out that the votage rgulater where you turn it up or down with a small screewdriver was bad so 2 day im going to replcae it,

 

i need this adjustment pot anyone kno which one i need the ohms or v?
the pre owner broke it, he turn it all the way around and now i cant ajust the volts going from main bord to dc-dc bord

 

 

ve on the dc-dc Bord needs to be about 80~120 and its like 10.0 something that
and the va on the main bord needs 60~80v and its putting out 450~657 and i cant adjust it on the pot
