Hitachi CT-7883BC Can't Post

Hello

Need help,I am working on a Hitachi CT-7883BC, Chassis number A1LXU-M/R.

I have repaired it to the point that it works fine,Picture,sound,.Funny thing is

when I use a universal remote it changes channels fine,up and down etc.Volume

up and down great.But when I go to use the front buttons on the tv itself,The power

button on and off okay,channel up and down has a tendecy to do the volume up

and down instead. Then if I push the channel up or down button again it seems to

be fine.I check the push buttons on the board with a DMM and seem to check out

fine. Any suggestions Thanks Rob

Board is contaminated or one of the stand off resistors has gone out of tolerance.
