Checking below to make sure power block is working:

1. F1, power to inverter, open?
2. F2, power to system, open?
3. TP 11 = 18V? If not, check power adaptor.
4. TP2 = 5V?
5. TP12 = 3.3V?

If checking below were all right, panel failed:

1. Power fuse F3 to panel open?
2. Power output to panel = 3.3V (F3)?
3. H-sysc output normal (IC 10 pin74)?
4. V-sync output normal (IC10 pin73)?
5. Panel clock normal (IC10 pin44)?

Checking below to identify scaler function, if output abnormal, the scaler chip failed:

1. Check IC10 power input from TP12 = 3.3V?
2. H-sync input TP18 normal?
3. V-sync input TP17 normal?
4. OSD clock IC10 pin117 normal?
5. Scaler clock input IC10 pin141 normal?
6. Video input IC10 pin 95/91/87 (R/G/B) normal?
7. H-sysc output abnormal (IC 10 pin74)?
8. V-sync output abnormal (IC10 pin73)?
9. Clock output to panel abnormal (IC10 pin44)?

If checking below were all right, CPU socket or CPU has problem:

1. Power to CPU pin-8 +5V normal?
2. Reset to CPU (TP6) normal?
3. V-sync input TP18 to CPU normal?
4. H-sync input TP19 to CPU normal?
5. IIC signal SCL-MCU output (TP4) abnormal?
6. IIC signal SDA-MCU output (TP7) abnormal?
7. CPU clock in/out Pin 11/12 normal?
