SAFETY CHECK-OUT
(U.S. Model only)
After correcting the original service problem, perform the following safety checks before releasing the unit 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 B+ and HV to see if they are specified values.
Make sure your instruments are accurate; be suspicious
of your HV meter if sets always have low HV.
8. Check the antenna terminals, metal trim, “metallized"
knobs, screws, and all other exposed metal parts for AC
Leakage. Check leakage as described below.
LEAKAGETEST
The AC leakage from any exposed metal part to earth ground
andfromallexposedmetalpartstoanyexposedmetalparthaving
a return to chassis, mU.S.t not exceed 0.5 mA(500 microampere).
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 instructions.
2. A battery-operated AC milliameter. 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 mU.S.t have an accu-
rate low voltage scale. The Simpson's 250 and Sanwa SH-
63Trd are examples of passive VOMs that are suitable.
Nearly all battery operated digital multimeters that have
a 2V AC range are suitable. (See Fig. A)

SECTION 3
SYSTEM DIAGNOSTICTEST
3-1. INTRODUCTION:
The following procedure is to test the WebTV (INT-W200/WJ200).
3-2. TEST EQUIPMENT REQUIRED:
1. PC (use Windows '95)
2. Oscilloscope (HP) or equivalent.
3. Digital Meter (FLUKE 87) or equivalent.
4. Donglizer (provided with WebTV)
5. +5Vdc Adapter
6. Two D-Sub 9 pins (female connector)
3-3. COMPUTER SET-UP:
1. Open "Start Windows," go to "Program," click on "Accessories," and select "Hyperterminal."
2. Click the "Hyperterminal" icon, and under "Connection Description", enter name and click "OK."
3. In the "Phone Number" window, connect using: select Direct to COM1.
4. Under "Port Settings," set as follows:
Bits per second: 19200
Data bits: 8
Parity: None
Stop bits: 1
Flow Control: None
3-4. TEST PROCEDURE:
1. Connect the WebTV unit to PC terminal as shown in Figure 1 below.
2. Energize the WebTV unit.
3. The computer monitor will show the list of diagnostics choices.
4. In order to select a test, type the number associated with the test on the keyboard, and press "enter."
The output data will appear on the screen.
5. To save the data, go to the "Transfer" menu, select "Capture Text," and click "Start."
6. The data you captured will be in the Hyperterminal folder.
7. In order to read the data, confirm that the "Append line feeds to incoming lines ends" option is selected in the
ASCII set-up menu.
Note: Two D-sub 9 pin configuration connections: Pin5 to Pin5, Pin2 to Pin3, Pin3 to Pin2
