SAFETY CHECK-OUT
After correcting the original service problem, perform the
following safety checks before releasing the set to the customer:
1. Check the area of your repair for unsoldered or poorly-soldered connections. Check the entire board surface for solder
splashes and bridges.
2. Check the interboard wiring to ensure that no wires are
“pinched” or contact high-wattage resistors.
3. Check that all control knobs, shields, covers, ground straps,
and mounting hardware have been replaced. Be absolutely certain that you have replaced all the insulators.
4. Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair. Point them
out to the customer and recommend their replacement.
5. Look for parts which, though functioning, show obvious signs
of deterioration. Point them out to the customer and recommend their replacement.
6. Check the line cords for cracks and abrasion. Recommend the
replacement of any such line cord to the customer.
7. Check the antenna terminals, metal trim, “metallized” knobs,
screws, and all other exposed metal parts for AC Leakage.
Check leakage as described right.
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground and
from all exposed metal parts to any exposed metal part having a
return to chassis, must not exceed 0.5 mA (500 microamperes).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA
WT-540A. Follow the manufacturers’ instructions to use these
instruments.
2. A battery-operated AC milliammeter. The Data Precision 245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operated AC voltmeter. The “limit” indication is 0.75 V, so analog meters must have an accurate lowvoltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOMs that are suitable. Nearly all battery
operated digital multimeters that have a 2 V AC range are suitable. (See Fig. A)

Twin View
Problem Possible Remedies
I cannot get Twin View to work s If you are using a cable box to unscramble all channels (as shown on page 26), you
cannot use the Twin View feature. This is beca use the cable box can unscramble
only one channel at a time. But if you need the cable box to unscramb le only some
(usually premium) channels, you can use Twin View for unscrambled channels if
you connect both a cabl e and cable box, as shown on page 25.
s You can use T win V iew to view a signal from a different source that is connected to
the TV's A/V jacks (such as a VCR or DVD player) in the second window by
pressing the TV/VIDEO button while in Twin View.
s Digital sources, as well as any sources connected to the VIDEO 4, VIDEO 5,
VIDEO 6 inputs, display in the left window, but not in the right windows.
There is no Twin View window,
or it is just static
s Be sure the Twin View window is set to a video input or channel that has a signal
airing.
s You might be tuned to a video input with nothing connected to it. Try cycling
through the video inputs by pressing the TV/VIDEO button.
Twin View cannot displa y
anything but TV channels
s Try cycling thr ough the video inputs by pressin g the TV/VIDEO button. Check
that the Label Video Inputs option is not set to Skip. (See the Setup Menu on

insufficient
s The TV’s audio might be set to Auto SAP or Mono, when it might be better set to

s Video head interference. Keep your VCR away from the TV.
s Leave a space of 30 cm (11 7/8 inches) be tween your VCR and the TV to avoid
noise.
s Avoid installing your VCR in front of the TV or at the side of the TV.
Image left on screen s Perform image retention recovery. (see page 98)
s Use the Screen Saver function (see page 98).
The screen flickers when
turning on the TV.
s This is caused by feature of the Plasma Display Panel, and does not indicate a

ìBlack boxî on screen s You have selected a text option in the Setup Menu and no text is available. (See
page 104 to reset Setup selections.) To turn off this feature , set the Caption Vision
option to Off. If you were trying to select closed captioning, select CC1 instead of
TEXT 1-4.
Bars appear at the top and
bottom of the screen
s Some wide-screen programs are filmed in aspect ratios that are greater than 16:9,
such as 2.35:1. (This is especially common with theatrical releases). Your TV will
show these programs with bars at the top and bottom of the screen. For more
details, check the documentat ion that came with your DVD (or contact your
program provider).
Certain programs on DVD or
other digital sources display a
loss of detail, especially during
fast-motion or dark scenes
s The compression used by certain digital broadcasts and DVDs may cause your
TVís screen to display less detail than usual, or cause artifacts (small blocks or
dots, pixelations) to appear on your screen. This is due to your TVís large screen
and ability to show very fine detail, and is normal for certain digitally recorded
programs. Adjust the reality/clarity in the DRC Palette option (see page 93) to
optimize the picture while viewing these sources.
