Procedure

Adjustment

Input Signal

Adjusting Point

Adjusting Method VRN (minus reset power supply voltage) Check the drive voltage label value at the top inside the unit, adjust VR4002 so that value between TP4021 (VRN) and TP4022 (RNGND) becomes this value.

VRN, VH voltage adjustment

All white 100% signal

VR4002 (VRN) (X DRIVE (A) Assy) VR5002 (VH) (Y DRIVE (A) Assy)

VH (scan IC power supply voltage) (Note 1) Check the drive voltage label value at the top inside the unit, adjust VR5002 so that value between TP5035 (VHY) and TP5034 (GNDH) becomes this value. Note: When the VRN voltage adjustment is not performed properly, dot-like blinking luminance points appear. If deviated greatly from the right adjustment, PDP will stop discharging. When the VH voltage adjustment is not performed properly, dot-like blinking luminance points appear. If deviated greatly from the right adjustment, these will become white. Check the pulse value when replacing the DIGITAL VIDEO ASSY and set the data again for the new Assy with the DIP SW.

Note: If set incorrectly, the number of drive pulses generated will change, and affect the brightness of the screen. PD operates if the power consumption exceeds the normal level. Check the waveforme shown in Fig.4 at TP4027 (XPSUS), TP4012 (XPSUS) on the X DRIVE (A) ASSY and X DRIVE (B) ASSY, TP5004 (YPSUS), TP5002 (YPSUS) on the Y DRIVE (A) ASSY and Y DRIVE (B) ASSY, then look at the waveform of the scanned portion, and find the sub field with sustain emission (refer to Note 2: Sustain emission.) Enlarge the waveform of the sustain pulse portion shown in Fig. 4 in the sub field with sustain emission, and adjust as shown in Fig. 5. If not adjusted properly, the slanting portion and base portion will distort as shown in Fig. 6 and Fig. 7.
Enlarge this portion, and check that this is the sub field with sustain emission Typical sub field adjustment for Y P.SUS Enlarge this portion and adjust the pulse width

Note: When the adjustment is not performed properly, dot-like blinking luminance points will increase. Memory data (CONTROL ASSY) When replacing the CONTROL ASSY, read the following data before ASSY replacement. 1) picture quality, white balance, phase data 2) HOUR METER data (Panel operating time from shipment) Set the above data again for the new ASSY using the RS232C command.
