Question about Zenith IQZ60Z97D 60 in. Rear Projection Television
I upgraded the stk ic's to 150's I replaced the 1ohm resistors r 4161,r1460,r4162,r4163. r4161 was at 2.4 and the rest were at 1.5 I also checked r 4151 it was at 999ohm so I left it alone. there was no 4160 resistor on the conv board or the schematics I still have the same 3 bowed lines on top from corner to corner and the green bow across the bottom any suggestions .still no picture or menues.
The 999 ohm is probably the bad one thats high for a conv ckt. also i would use the amps the tv calls for that upgrade stuff does not always work out like you think it should.

the r4151 is supposed to be 1k so I thought 999 ohm is almost perfect. I dug into the smps module and pulled the r3243 which is supposed to be 110k and it weighed in st 1.2 meg and climbing so I will pick one up after my 4 12hour dayshifts and put it in I think this might be it because this resistor cuts power to the whole converegence circuit I think?? I will let you know if it does it and thanks form your input if the high heat (150) stk's won't go I will put the old 110's back in
Oh ya the r4151 is a 1k smd resistor(soo tiny I would rather not change it if possible)
the r4151 is fine I changed the r 3243 and the tv came on perfectly .Also the stk 150's that I put in as an upgrade for the stk 110s also are working great I am now finishing the 88 step service menu setup and the convergence and picture are very nice
