Plasma Pn58B650 clicks on and off, after replacing y board with blown fuse

[chaswee1]

Upon plugging in the TV, a red readiness light blinks is then it goes into looping click on/click off cycle. Once this takes place, I have to unplug the TV to power down as the remote & pad become unresponsive. I have ohm tested all the fuses & found them to be good. I located a blown ceramic fuse on y board jumped it out and burened up a fet. I oreder used replacement y board. Unplugging individual boards as follows continue the clicking cycle: y-sus, x-sus, logic or control? I tried jumping the #3 & 4 pins on the logic board while jumping out ps on to ground on power cable coming from power supply to main board. also disconnected lsvd cable. Tv went into test patterns and patterns look good. I saw this on you tube. Video says to suspect lsvd cable or main board. I ordered used main, installed and tv repeats original faoult. I am going to order another main this time from Jimmy. P.s. also replaced logic board before this same results, both logic boards pass test pattern. I waiting for replacement main, could there be another problem if new main board act the same?

Your problem, from what you have described, is more than likely on the main board.

I was unaware of this site. I did a lot of research and based on what I learned thought the same. I also followed similar posts of yours and it reinforced the idea I may have order a faulty used main board. I will install new used replacement main board when it arrives and post how I make out.

I just replaced main board. You can hear the tv speaker when turning on and off. Tv does not click any more. I can turn on and off. when I first put on I get slight white light for an instant then screen stays black. I attemted menu with remote and button on tv, still no picks.

It's more than possible your new main board is bad, since the test patterns worked you've proved basically everything except the main board as working. Also check LVDS cable is seated properly and 3-4 jumper is removed.

I left plug disconnected from y board to the lower boards. I did the pattern test jumping out pins 3 and 4 and got no patterns. I relized then to double check all connection and I caught where I forgot to plug back in. I then plug back in and tv fired up. Thanks.
