Board/CPU bundles are so inexpensive, I almost always recommend replacing both
when either fails. (for example, starting at $59.95 from www.tigerdirect.com )

That model set had a manufacturing defect. The 10 watt resistor was sized
too small. Most sets had the resistor changed under warranty to a larger
wattage.
Setting the G2 is done the way already mentioned, turn it up untill you
get retrace lines and back it down.

Increasing capacity induces similar effect as with wrong bias - pops on bass
peaks, although there is more LF in the signal. I checked everything
thoroughly and there is still some distortion caused by wrong replacement
transistor. New 2N3055 goes better in pair with 2N3055U than with 2N3055G as
a 2N3055K substitute. The amp is a vintage ELAC 4101T quad receiver (mid
70s). It's powered by single 60V winding transformer followed by Graetz
rectifier, there is no +/- 30V symetry, there are only 30V dividers in form
of slot-in cards which I can exchange for troubleshooting and 27V AC
feedback from additional transformer winding. 2N3055K works in 60/30 V area,
while 2N3055U is connected to the speaker out.

But now some questions. The remembered visual patterns I recognize as

animals apparently rely on remembered patterns. There's no necessary
self-awareness involved, no reflexivity other than an association of
the visual image and the remembered pattern. Neither does my smile
seem to represent consciousness; it seems nothing more than a
culturally learned instinctive reaction to pattern
recognition. Animals do much the same. My instinctive sense is that
consciousness reaches beyond these elements or their connection. For
one thing, it seems to require that we see ourselves or have a sense
of our ego. In fact, consciousness seems close to what we mean by ego,
an identification of self as separate from the rest of the world.
However, I'm not entirely comfortable with this line of argument, for
it seems to depend too much on human individuation, which in turn is a
historic product. In anthropological terms, the rise of consciousness
may perhaps be associated with humans beginning to map their world
beyond immediate experience, such as knowing about the availability of
chert from a distant site learned about, but never seen. If we were to
accept this kind of argument, then consciousness seems to precede
individuation. I'm drawn back to my earlier point about the individual
seeing himself as an agent, separate from and acting upon the world,
but this can be either as a social agent or as a distinctive individual.

seems to persist (their essential qualities rather than their

abstraction, I don't know. But a pattern recognition based on the
abstraction of things' persistent qualities I suspect is true of
animal pattern recognition as well. We can attach a symbol, a verbal
sound, a word, to those patterns in order to communicate them to each
other. However, if a bird sends out an alarm call because it sees a
pattern suggesting danger, how does that differ in principle from what
I just described?
I mention parenthetically that this kind of mental operation, which
seems obvious, may not in fact be universal. That is, it is based on
the practical needs of daily life. But if the temporal or geographic
scope of our concern widens significantly beyond the world of the
individual--particularly the needs of daily life, then what seems most
fundamental is no longer persistence or simplicity, but change and
complexity. Persistence or coherence then becomes problematic, the
exception that begs for explanation. This problem comes up in
connection with world historiography, but more importantly, our
significant worlds may no longer be local, but global, so that what
happens in the Cote d'Ivoire is as important as what happens locally,
affecting me just as profoundly. Globalization might be creating
conditions in which empiricism ceases being practical, and we begin to
act as global social beings in a world of extraordinary complexity and
fluidity. Sorry for this aside.
In short, I see the recognition of the pattern of oranges and our
ability to communicate about them as a natural development of what
animals do, and even if attaching verbal symbols to these remembered

reflexivity and perhaps agency that we both insist must be central to
consciousness?

and distinguishes human from animal consciousness, reduces reflexivity

The must common faults of a missing color are:
1. A break in the color video signal wire within the video cable.
This usually occurs near the end that connects to the computer.
Try bending the cable and see if the color comes back.
You can purchase new 15 pin ends at Radio Shack and solder a new
end on the cable.
2. A bad solder connection at the socket where the CRT circuit board
plugs onto the back of the picture tube. Just resolder the connections.
3. A bad video driver transistor or driver IC that supplies the color
signals to the picture tube. Measure the voltages on the three color
signal connections on the picture tube socket. The missing one will
usually be very different.
The driver IC that you mentioned would be located on the CRT neck board.
I would download a standard color bar program from the web to determine
which color is actually missing. There are also pinouts on the web that
indicate which pins do what functions on the picture tube socket.
Hope this helps...

I've no schematics, but seems like a pretty regular switching power supply

straightforward. Since some voltages are OK, the primary side is probably
fine. Look at the secondary side, especially those outputs that fail. Check
diodes and electrolytics. If you can't those caps, just replace them.

My method for diagnosing boot problems is to disconnect or remove -
Diskette Drive, Hard Drive/s, Video Card, any other card/s, RAM Dimm/s -
basically leave the motherboard and processor.
In that state the PC should make a sequence of beeps indicating the lack of
RAM. The display is not necessary. If there is no life from the motherboard,
it is either that, the processor or power supply. If there is a sequence of
beeps where before there was no sign of life, I would then replace all
components one at a time, starting with the RAM, until the problem recurs.
By the way, If there is no life from the system board with everything
removed I would also suspect the processor fan, as most of them use dodgy
bearings that are prone to seizing up. If that has happened there is a high
probability that the processor had cooked, in which case you could either
find a compatible processor (probably second hand) or, as you did, use it as
an excuse to upgrade to a better motherboard/processor combination.
