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 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.

Voltmete (0.75 V)
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 microampers). 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)

POWER SAVING FUNCTION
CPD-E220/E215E/E220E
This monitor meets the power-saving guidelines set by VESA,
E
NERGY STAR, and NUTEK. If the monitor is connected to a computer or video graphics board that is DPMS (Display Power Management Signaling) compliant, the monitor will automatically reduce power consumption in three stages as shown below
.
Power mode Power consumption 1 (power)

DIAGNOSIS
This monitor is equipped with a self-diagnosis function. If there is a problem with your monitor or computer, the screen will go blank and the 1 (power) indicator will either light up green or flash orange. If the 1 (power) indicator is lit in orange, the computer is in power saving mode. Try pressing any key on the keyboard.
* “Sleep” and “deep sleep” are power saving modes defined by the
Environmental Protection Agency.
** When your computer is in a power saving mode, MONITOR IS IN
POWER SAVE MODE appears on the screen if you press any button on the monitor. After a few seconds, the monitor enters the power saving mode again.
If all four color bars appear (white, red, green, blue), the monitor is working properly. Reconnect the video input cable and check the condition of your computer.
If the color bars do not appear, there is a potential monitor failure. Inform your authorized Sony dealer of the monitor’s condition.

2
Press the 1 (power) button twice to turn the monitor off and then on.
3
Move the control b utton , for 2 seconds before the monitor enters power saving mode.
MENU
If the 1 (power) indicator is flashing orange
Press the 1 (power) button twice to turn the monitor off and then on.
If the 1 (power) indicator lights up green, the monitor is working properly.
If the 1 (power) indicator is still flashing, there is a potential monitor failure. Count the number of seconds between orange flashes of the 1 (power) indicator and inform your authorized Sony dealer of the monitor’s condition. Be sure to note the model name and serial number of your monitor. Also note the make and model of your computer and video board.

REMOVAL OF ANODE-CAP
NOTE: Short circuit the anode of the picture tube and the anode cap to the metal chassis, CRT shield or carbon painted on the CRT, after
removing the anode.
REMOVING PROCEDURES
b
a
1 Turn up one side of the rubber cap in
the direction indicated by the arrow A.
2 Using a thumb pull up the rubber cap
firmly in the direction indicated by the arrow B.
HOW TO HANDLE AN ANODE-CAP
1 Don’t scratch the surface of anode-caps with sharp shaped
material!
2 Don’t press the rubber hardly not to damage inside of anode-
caps! A material fitting called as shatter-hook terminal is built in the rubber.
3 Don’t turn the foot of rubber over hardly!
The shatter-hook terminal will stick out or damage the rubber.
c
Anode Button
3 When one side of the rubber cap is
separated from the anode button, the anode-cap can be removed by turning up the rubber cap and pulling up it in the direction of the arrow C.

SAFETY RELATED ADJUSTMENT
CPD-E220/E215E/E220E
When replacing parts shown in the table below, the following operational checks must be performed as a safety precaution against X-ray emissions from the unit.
Part Replaced ( ] )
HV Regulator Circuit
HV HOLD DOWN Circuit
Beam Current Protector Circuit
Allow the unit to warm up for one minute prior to checking the following conditions:
a) HV Regulator Check
1) Input white cross hatch signal. (fH = 69 kHz)
2) CONT maximum and BRT center
3) Cut off Screen VR (G2).
4) Input voltage: 120 ± 2 VAC
5) Confirm that the voltage is within the voltage range shown below.
Standard voltage: 26.9 KV ± 0.4 KV
6) When replacing components identified by ], make sure to recheck the High Voltage.
7) Verify the High Voltage as shown above (26.9 KV ± 0.4 KV) is within specification. If not, set H. SIZE data at minimum (-127) and then adjust VR501 on "D" Board.
D board IC502, T501 (FBT)
D board D538, R521, T501 (FBT)
D board IC901, R949, T501 (FBT)
8) After adjusting the High Voltage within specification, put the VR cover on VR501 as shown below and apply sufficient amount of RTV around VR501.
b) HV Protector Circuit Check
1) Confirm that the voltage between cathode of D517 an GND is more than 27.5 VDC.
2) Using an external DC Power supply, apply the voltage shown below between cathode of D517 on "D" and GND, and confirm that the HV Hold-Down circuit works. (Raster disappears) Apply DC Voltage: Less than
35.8 VDC.
Check Condition
• Input voltage : 120 ± 2 VAC
• Input signal : (fH = 69 kHz), White Cross Hatch
• Controls : CONT (max) & BRT (center)
• B+ Voltage : 179 ± 3.0 VDC
c) Beam Protector Check (Software logic)
1) Using an external current source, apply < 1.55mA between pin qa of FBT (T501) and GND, and confirm that the raster fades out.
Check Condition
• Input voltage : 120 ± 2 VAC
• Input signal : (fH = 69 kHz), White Cross Hatch
• Controls : CONT (max) & BRT (center)
VR501
d) B+ Voltage Check
1) Input white cross hatch (fH = 69 kHz) signal.
2) CONT (max) & BRT (center)
3) Input voltage: 120 ± 2 VAC Note:Use NF power supply or make sure that distortion
factor is 3% or less.
4) Confirm that the voltage is within the voltage range shown below.
Standard voltage: 179 ± 3.0 VDC
