Title: matsui 42p900 plasma (using l.g.p42v7 series panels.
Post by: maff99 on May 20, 2008,12:46:52

Hi guys,The ysus p.c.b. failed on this set,so I ordered panel kit from c.h.s.tried fitting all three panels in kit but end up with no picture but sound.My control p.c.b. is larger than the new one in kit & is marked6871qch053c(not on the list)if I leave the new ysus/zsus p.c.b's in & the old control p.c.b. the set then gives a picture but very noisey in back ground no amount of setting up seems to alter this.any body got any ideas before I go mad & do something I might regret later to this fine example of modern tech.  :oops:

very easy heres what you do fit the new 42v7 y sus & z sus boards only with your old original logic board so fit the 2 big boards & leave the original logic board in the tv as the logic boards that come with the 42v7 kits dont give any picture do that and your set will be ok

if its giving a dark picture with a new y sus and z sus then you need to replace the ctrl logic board with the correct 1 of the same number which is found in the pdp42v7 range of plasma"s the original logic board is prob duff if its sounds loud

Hi Mulja, it usually works ok with old logic board,I have done this a few times. Charles Hyde seem aware of the problem and advise using old logic board. It doesn,t seem to do any harm. Norman
