Re: LG 42LC2D no picture

I'm still looking for help with this issue. If anyone has any advice I would appreciate it.

Re: LG 42LC2D no picture

Sorry. I must have had the range too low.

AC DET - 0v
RL ON - 1.85v
ST 5V - 4.98v
GND - 0
INV ON/OFF - 0
5V MNT - .08v
POL/INV - 1.112v
ST 5V - 4.96v
GND - 0
PWM - .10v
6.0 V - 6.13v
GND - 0
LIVE ON - 1.476v

It looks like the inverter power supply voltages are all above 24v. Thanks for your help.

Re: LG 42LC2D no picture

I took these readings this afternoon. The second 5V pin was steadily dropping. When I first took the reading, it was showing almost 1.5v.

AC DET - OL
RL ON - 1.85v
ST 5V - OL
GND - 0
INV ON/OFF - .012v
5V MNT - .072 dropping
POL/INV - 1.112v
ST 5V - OL
GND - 0
PWM - .118v
6.0 V - OL
GND - 0
LIVE ON - 1.476v

I have an LG 42LC2D tv that recently lost picture. When I turn the unit on I get a click, the red standby light blinks green 12-14 times and then turns solid. When I press the power button, it takes several seconds to turn off. I have replaced several caps including one visibly blown one. The unit is still not working. I started disconnecting wiring harnesses. When I disconnect the 13 pin harness, the unit will power on correctly, but still no picture. With the set still on, I reconnected the harness and I have video. The pictures included have the harness I am talking about circled. Any ideas?...

I'm new to the board. I'm just a husband and dad who seems to find himself having to fix various things around the house. Sometimes necessity is the mother of invention. In other words, I'm cheap and I prefer fixing things when I can. Thanks in advance for any help I might get.

Re: LG 37LC2D No picture, believe bad power supply

Is there anyone still monitoring this thread?
