Re: GO7 B+ low



Wow.........

The reason I mentioned the flyback and HOT is because they were both changed
when I did the cap kit a few days ago. I always rebuild any GO7's I plan to
keep with flybacks, hots, and cap kits and this one was no exception.
Considering I'm looking at the 900 series components in the power supply
section, I guess mentioning the hot and flyback wasn't necessary, but
neither was the tone of your reply.

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.
