Hi Members;
There was some duscussion a while back, about which STKs should be used as a
replacement for the STK392-110, on the Hitachi PTVs. Is it OK to use the
STK392-180 ? (Most of you said to use the STK392-150.)
I have been using the STK392-180 on Toshiba, and Mitsubishi PTVs with good
results. I see no reason why they cannot be used on the Hitachi PTVs.
I'd like the rest of you guy's opinions on this matter.
I replaced BOTH STKs on the above model, for blue off to the right about 2
inches, and no adjustement activity. I also replaced RK50 (2.2 ohms). Now the
Blue is off in the opposite direction (to the left about 1/2 inche), with still
no adjustment activity.
Do you think I have a voltage missing, another open resistor, factory menu
default problem, DCU board problem, or could it be that I used the wrong
replacements for the STKs ?
I have downloaded the service manual from the Hitachi web site, and the service
bulletins that apply to this model. I now have the set here in the shop, after
making 3 trips to the house.
TIA,
LLW
