1. Open internal fuse
2. Power supply failure
SOURCE: LG Flatron L1550S power light blinks green.
shorted components on the circuit. send it to a repair shop if you don't have experience on electronic troubleshooting!!!
SOURCE: No picture, but power is on...
How many times does the POWER led blink per sec? (dont worry about the OPC)
2x = power supply (not as expensive to fix)
3x = Main board (expensive to fix)
SOURCE: LG 50PC3D PLASMA WILL NOT TURN ON
Unplug power cord- safety first!
open backcover
check powersupply- top center right is p.s.
top left side of powersupply you'll see 5 capacitor 3300uF 10V.
see any pop up on top? replace it All with same rate or 16v is O.K.
do not use temperature rate 75c. Use 105C.
if you know how to solder. you save $300 least!
SOURCE: red blinking light when tv is turned off
if this is a 37lg30 i have brand new spare parts. the tv was never used it was dropped and the screen was damaged so i just took out the parts out. i was originally looking for some one that had a problem with there tv but a good screen like you but its easier to ship out the boards.
SOURCE: blinking green light no picture for a lg lcd tv
We have a bunch of 23" LG units that all failed with the flashing green light problem. I opened it up and traced it to a bad 3.4v output on the power supply which was caused by a puffed up capacitor on the board. If you are capable, you can do the repair and they have all worked fine since. BTW, they ran 24h a day for 2 years before this happened.
