This set came in with pix bowed at top and bottom.Both red and blue way
out.I replaced both ic's stk-392-110 and R3243 and R3244. R3243 was
open.After all this,I powered the tv on and did some minor touch-up on
the convergence and the pix is nice.After running for about 20 to
30min,I noticed that the color changes from normal to a high green and
then goes back to a good pix.I thought a may be a bad green crt but it
tests ok.
This set does not use the crt bds that had the R5102 (120K) that would
open or change in value and would cause this problem.Is there any notes
on winstips for this model concerning the color change.Maybe someone has
had this problem and can give me some help.Thanks foer your help.
