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)

1) *Operation count is based on WDT. *For flashes, the Power/Standby LED flashes in red. *The flash period is based on the reliability standard.

*A failure part can be expected by the number of times of blink of LED. *When two failures occur, the failure item generated previously is detected. *When failure occurs simultaneously, an item with little number of times of blink is detected. *In other than

“Fan Error”, the unit is in standby state and blink LED at intervals of regulation. In “Fan Error”, the unit is in a standby state after display for 1 minute about the message of “Fan problem – Powering down”

2-2. White Balance Adjustment (PDM-6100)

2-2-1. Measurement equipment

1. Color analyzer (CA-100 manufactured by MINOLTA)

2. Signal generator (ASTRO DESIGN VG-828D)

2-2-2. Measuring procedure

1. Dab the W/B adjustment jig (CA-100) at the glass face of the panel.

2. Connect the Signal generator (VG-828D) to the DVI terminal.

3. Input All-white signal and set the picture mode to DYNAMIC.

4. Select”PNLCTRL” in the service mode menu and set “0 WBNO” at “0”

5. Select “SCNR” “SCNB” of “PDPWB” in the service mode menu, and then adjust following W/B standardized values of 6500K, 8000K, 9300K, 10000K and 13550K to following values of X/Y.

W/B standardized values:

6500K+8MPCD

W/B

0.3133 ± 0.003

X

0.3297 ± 0.003

Y

6. After adjusting the values, at the values of the “SCNR” or “SCNB” exceeding 128 (initialize value).

1) Reset a lager value of the “SCNR” or “SCNB” at 128.

2) Set the White Balances with the last of items and “SCNG” to the X/Y values above.

7. After the above step, when these item are nonqualified following conditions, set the largest one at 128 and readjust the White Balance with the last two item.

1) No one of “SCNR”, “SCNB” and “SCNG” exceeding 128

2) Confirm the item value 128 at least one item

8. As a result above, input the sequential number of value to the “SCNR”, “SCNB” and “SCNG”.

9. Repeat the same step 5 thru 8 for the W/B 1 thru 4 after setting the “0 WBNO” at each W/B number.

10. Input following signals from the Signal generator (VG828D).

1) All-white signal (255/255) input

Y (luminance)=45cd/m

2) 1/25Window (255/255) input
