Troubleshooting
1) Definition of a Logic Circuit
A Logic Circuit consists of a Logic Main Board, which decodes the video signal encoded on the Video Board, outputs the address
data signal, and generates and outputs the X, Y drive signals, and an Address Buffer Board which buffers and outputs the address
data output signal to the TCP IC.
Logic Board Function Remarks
- A built-in LVDS for video signal processing (W/L, Error Diffusion,
APC, FCR, etc.) adopted and 1 ASIC chip.
- Outputs the Address Drive IC control signal and data signal to
the Buffer Board.
- Outputs the X and Y Drive Board control signals.
Logic Main
- Monitors the major drive voltages (MICOM circuit part)
; Detects any surge voltage to protect the drive circuit.
- Temperature Adaptive Operating Mode (Low Temperature /
Room Temperature / High Temperature)
; Optimizes discharges depending on the temperature.
Buffer Board Lower Part E Buffer Board Delivers the data and the control signals to the bottom left TCP. Single Scan
Lower Part F Buffer Board Delivers the data and the control signals to the bottom right TCP.
2) Waveform for Normal Operations
When the PDP and the Logic Board are normal, the Operating LED blinks at a half second interval. In this case, the V-SYNC and
data signals are output normally.
In case of problems with the product, please refer to the troubleshooting procedures described below.
Visual Inspection: Check if the Operating LED on the Logic Main blinks at a half second interval.
If the frequency of the blinking is too fast or slow, it means that the MICOM has failed to process the data properly.
Therefore, you have to reload the data onto the MICOM. Load the data using GA-WRITER when the power is
connected to the module.
If no problem is found during the Visual Inspection, check if the drive waveform and the address data outputs are normal using
an oscilloscope. (Checkpoint: The DAMPING R-NET part output of each data output terminal.)
If no drive waveform or address output is measured, this means that there is a drive problem due to MICOM data corruption,
which was the reason in the Visual Inspection. Therefore, in this case, reload the data as you did in the Visual Inspection.
When data output is measured but it is abnormal, and the drive waveform is abnormal, it is probably due to a short-circuit of
the hardware. If the address data is abnormal, the screen may be abnormal due to abnormal data output by an abnormal
operation of the DDR memory due to an abnormal Vref voltage, or the screen may be abnormal due to a short-circuit in the
ass'y inside the board. You have to conduct a short-circuit test for each case.
If the Vref voltage (the voltage of the Voltage Divider) is lower than 1.25V, check the resistance of the resistance output part
and check if the circuit is normal. If the Vref voltage is normal, the screen operates normally.
If the screen is abnormal, even though the Vref voltage is normal, check if there is a short circuit by conducting a
short-circuit test. If a short-circuit is found, repair it. If the short-circuit is an internal one, replace the board.
The following waveforms represent normal V-sync and address data output waveforms.
