LG 37LF65 LCD TV BLINKS 3 GREEN THEN 1 RED THEN TURNS OFF.

LG 37 INCH LCD TV BLINKS 3 GREEN THEN 1 RED THEN TURNS OFF SOMETIMES WHEN YOU TRY TURNING IT ON, WHEN IT TURNS OFF THERE IS NOW LIGHT ON AT ALL ON THE STANDBY INDICATOR. IT GOES BACK ON WHEN YOU TAKE THE PLUG OUT FOR BETWEEN 5 MINS TO 30 MINS. DON'T KNOW IF IT IS A COINCIDENCE BUT IT STARTED WHEN WE INSTALLED A WII CONSOLE. PLEASE HELP AND FORGIVE MY CAPITAL LETTERS AS IT IS TO DO WITH SLOW TYPING. THANKS, BRYAN.

Here's a link to the service manual for a slightly larger LG LCD TV. Perhaps it may be of some help? The troubleshooting section appears to be the same for many models of LG TVs...

It would be the best to measure the voltages on the power suply 12V 24Vand all low voltages, then check for the bouiler capacitors in secondary. If everything is ok then check the inverter on voltage, If everything ok then the inverter board is defective

Red light blinking shows some kind of internal problem during circuit check and protection got activated upon some failure.
Count the red light blink as you will see 3 second long pause and post it here to diagnose what section of tv got problem.
Did you replaced its lamp in last 2-3 years?
Thanks.

I have a 37" Phillips LCD TV. it will not turn on and the light that used to show green (to signal the tv on) now blinks red. What does that mean?


how many times does it blink red. the will help determine whats wrong. Most lightly its going to give you 6 or 7 blinks whick points to the power supply this is sometimes a false indication to the ssb/signal board being bad. you coulb try the parts or have a tech come out and verify which is the problem.

BROKEN TV


Polaroid has a 1 year manufacturers in-home warranty on 32+ inch TV's. Contact them and they should send someone to fix the TV for you.

Since it is still under warranty make it Polaroids "problem"

hope that helps!
