Re: GO7 B+ low

did you read the flow chart I sent you? It said nothing about flyback,
hot.......sometimes I don't know why I bother anymore.

Yep turns out R908 is okay after I tested it out of circuit. I also pulled
and tested all 900 serieies resitors this way and found nothing wrong.
Monitor has a cap kit, new flyback, and new HOT.

Depending on the circuitry. Sometimes you have to pull the part out to
see what the actual ohms are but if you measured a good board with the
same 9kohms, I would say it's good. I sent you a flow chart that should
help.

Also look for bad solder joints and you may want to install a cap kit
since you have it out.

Interesting. I checked that one again and my meter is reading 9kOhm and
the manual says it should be 47kOhm. I remember seeing that earlier
today and being a bit confused because another working monitor and parts
chassis both tested 9kOhm on that resistor even though the manual says
it's 47kOhm. Aren't you able to test them in circuit or do you have to
pull them like diodes and transistors? I'm sure other resistors did test
out good in circuit. It seems odd that I'd have 3 chassis all with the
same resistor going bad.

Try replacing R908 then adjust b+

Hey all,

I've posted this on the KLOV forums, but I thought I'd see if I can
get some additional advice here. I have a GO7 with the B+ pot cranked
and I can only get it up to 117. If it's cranked the other way it only
goes down to 107. Interestingly, it stays at 107 until you have the
pot turned aobut 3/4's of the way open. That made me think the pot was
bad, but I took the chassis out and tested the pot and it seemed to be
working as it should. I've also pulled and tested X901 and 902 as well
as other 900 series resistors. My next thought is maybe the voltage
regulator transistor mounted on the side could be bad. I have a
reading of 154 into the large white resistor so I've got plenty of
input power. What risk would I be running if I leave the pot cranked
and run the monitor with the 116? Any thoughts on this are
appreciated. Thanks.
