Check the relays on the power supply board. A defective 5V relay part number LKS1AF-5V will prevent normal power up or power down.

Will Not Turn On


First you need to do a self test diagnosis and then if it comes up with:
SELF-DIAGNOSIS ERROR 23 OR 24. CHECK SOLDER CONNECTIONS AT CONNECTOR "DY" ON THE YOKES. 2. SHUTDOWN AT POWER WITH SELF-DIAGNOSIS ERROR 23 OR 24. CHECK C411 2200 UFD 35 V AND C412 10 UFD 50 V, BOTH LOCATED ON THE MAIN PCB
Do self test by pressing Input/Device and Menu at the same time for 5 sec. the set will show a 2 digit seq. first blinks followed by a short pause then the second.

LG 42 LCD no sound or picture


Did anyone find out the solution for this??????? I have the exact same problem with my LG 32 LCD. I only had it for a year and a half, and the green light blinks a few times and it shows no picture. Not even a red light when the tv is off. The same thing happened a couple weeks ago and by some miracle it started working again.
