I've owned this set for over twelve
years. When I first moved into my new home, I put this set in
temporary storage. Here is the set when I first brought it out of
storage. The swivel base was temporarily removed for transporting
the set. Inside and out, the set is thoroughly inspected. |
|
Although the original components still function, I have
opted for precautionary replacement of the "voltage-doubler"
capacitors in the low-voltage power supply. The new capacitors are
mounted under the chassis. The remainder of the restoration consists
of making the final "setup" adjustments. |
|
 |
The new capacitors help to restore full B+
supply voltage, which was only about 10% lower than the value specified in
the service literature, brightening up the picture noticeably. I also
performed preliminary grayscale setup. |
| The base is now reattached to the set's
cabinet. Proper adjustment of the HV Regulator helps to further
improve picture quality. |
 |
 |
Convergence and final grayscale tracking
adjustments are next. Overall, static and dynamic convergence
results are excellent for this type of set. |
| Overall performance is checked using several
test patterns. In this photo, a "gated rainbow" pattern is
displayed. Although not shown in the photo, a Vectorscope is
connected to the set during this test to evaluate the performance of the
chroma processing circuitry. |
