I am the one who has 10 of these 42`` samsung projection sets at work
all with convergence issues .
We ordered 4 of the 15$ sanyo STK-392-040 chips .

I replaced the 2 chips on one clean looking module , checked all the low
ohm resistors and found none bad so i went ahead and plugged the module
into one of the sets and it worked .
I continued to try the same module in 9 of the sets and they all worked
Some were super far off with the red so i quickly got into the manual
convergence and got it back into shape .
Tomorrow i will put those other 2 new chips on another board as before
and try my luck . If this goes good it looks like there will be hope for
some if not all of the other modules and tv sets .
Will they last ? I du-no ? I am thinking maybe Samsung got hold of a
big batch of not so good STK chips . Who knows !

Keep us POSTED!

Did you as I suggested by slapping some dollop of thermal grease on
removeable convergence module's heatsink area where it touches the
steel frame as well as the ICs?

Hi . No i used no grease , these IC packs sit on a thin insulating
rubber film . I am headed to work now to get stared on the second module
:-) wish me luck !

I put the new chips on the second module and it also worked . Both tv
sets were on all day today at least 9 hours and they stayed going . Both
of them sold today to !

Did all those sets just have bad pictures? I have one that won't power
up..I have replaced ic's before to correct this problem in other
projection tv's but not in this model yet....Did you have any power
on issues? Thankyou, joe
