    LG 42Pj350 ysus maldischarge

    Need assistance please

    I recently got in Lg 42pj350 with the usual y-sus problem,found four Igbts shorted 30f124 & 30J124 repalaced those refreshed the board then I examined the Z-sus board,to find the coil had dry joints..re-soldered most of that board...it came on nice,tested it for couple of hours

    I released it to the client,it came back five days later,I found all the Igbts I replaced before shorted with the addition of two fets...I replaced all these checked the board again,replaced it...now I have mal discharge ...what else can I do thanks in advance

              plasma TV Lg 42w451 - why is the zsus igbts damaged when the ysus is plugged?
              by Salvatore057
              Hi all,
              I am trying to fix my plasma TV which is not powering on due to damaged IGBTs. I have changed two igbts and 2 IC drivers on the zsus and also two igbts on the ysus.
              Now everytime I plugged the ZSUS and the YSUS boards to the power board, the two 30f124 IGBT on the ZSUS are damaged and the TV stays in standby mode. When I plug the ZSUS board alone the TV turns ON but I do not see pictures. When I plug the ZSUS board without the two 30f124 IGBTs and the YSUS board, the TV powers on with a picture.
              I am lost, should I change the YSUS board? Is the YSUS board damaging...

              LG 42PC3 buffer output doesn't follow YSUS
              by legg
              LG42PC3D -UD originally with green lamp but no display or audio.
              Owner says was working, then went 'pop'.
              All 5V caps bulging. replaced.
              All PSU output voltages within spec but -Vy is low on YSUS.
              One of three parallel fets between SUS_OUT and SUS_DN is zenering,
              eventually shorts DG. Replaced all 3 - -Vy now OK.

              Y scan buffer test point does not follow YSUS output below -50V

              Note: This unit seems to expect YSUS output to park at -Vy in between
              drive signal pattern periods. A replacement drive signal board confirms this....

              Help repair this relic? Philips 42PF7220A/37, pulsing buzz from YSUS
              by Truncatedhose
              Greetings all!

              Originally this set had the usual messed up video symptoms such as: horizontal lines, weak, grainy video, bottom and top of picture differ in intensity of problem. It also seemed to slow to turn on or show the messed up picture.

              Seemed like must be YScan/buffer board failure. Ordered buffer boards from my distributor which were supposed to be original/new and also from another distributor, I ordered the YSUS because I wanted to replace it for preventative maintenance. (also, the YSUS had a bulged cap, so there was even more reason to suspect it could...

              by zwarder
              Hi
              Had shorted YSUS

              Q24 RPJ63F3
              C726 cap
              Q11 K3667
              R528 & R529 2.2 ohm

              replaced all of these but still trips psu VS & VA are a bit low when ysus disconnected. IC301 does look a bit burnt however

              ZSUS is also good as far as I can tell

              Anyone could help me out on this one

              Panasonic TX-P42UT30E, IGBTs on the SN board
              by rivetcity
              Hi,

              I'm having problems with my plasma Panasonic p42txu32e. The issue started about 12 months ago.

              I have a remote controlled main outlet so whenever I turn off the TV set at night, I also switch off the whole power outlet.
              It gives me a better feeling to know I don't have 230V on any cables, so my dog can't get hurt if he gets the idea to start chewing on something.

              About 12 months ago the TV started to have the following problem: when pressing anything on the RC to get it on, the red led would go off.

              Sometimes it would turn...
