1. Description of trouble
RED LED continuous blinking Power supply sometimes cuts.
2. Fault Location
IC804 of Main Power PCB IC142 of Main Power PCB Resistor (1W, 1/2W, 1/4W) solder crack of Main Power PCB The noise does overlay to the VCC power supply of IC804 and it damages IC804. IC142 is destroyed due to the solder crack of the chip resistor.

4. Applicable Models
P42HHA10WS P42HHA10ES P42HHA10AS P42HHA10KS P42HHS10WS P42HCA10WS P42HCA11WS P42HHS10ES P42HCA10ES P42HCA11ES P42HHS10AS P42HCA11AS
5. Method of measures
Please surely execute 2 preventive maintenance.
The capacity of C836 is changed and the noise is removed. 1. Preventive maintenance The capacitor with the lead is added to C836 of Main Power PCB. For the prevention of the solder crack, solder is added. 2. Preventive maintenance Solder is added. R38, R39, R122, R123, R142, R143, R154, R155, R501, R583 R584, R632, R633, R634, R162 Each terminal of IC121, IC141, IC142 3. A case of LED lamp blinking Please exchange 1,2(Preventive maintenance) and IC804. Details : to next page.
6. Additional measures
Please execute preventive measures also because abnormality is seen in the shape of waves at the start. Parts are exchanged 1. R147 0.15W 2. R165 0.12W 3. R157 1.8kW 4. D145 ECSF56 5. D152 ECSF56 6.
