Question

LGE TV is taking longer on start-up to display a picture.

Mar 22, 2013 5:36AM PDT

LGE TV is taking longer and longer on start-up to display a picture. I may have to turn it off and on 7 or 8 times to get a pciture at all and it's getting worse. When I turn it on, the green light blinks and blinks and then goes steady, but no picture comes on. Then I have to hold in the Power Off on the TV to turn it off because it doesn't respond to the remote on switch off. Finally, after doing this for about 5 minutes, I get a picture. Occasionally a bright white light suffuses the screen but no picture appears. Finally, after turning it off and on many times, I get a picture but this problem is getting worse. Any ideas?

It's a shame the age was not revealed but google this to learn why this is a known symptom of an issue or plague.

-> BAD CAPS PLAGUE <-

Most makers are covering this one.

I think you've hit it! I googled "bad caps plague LG" and saw it's a common problem. Then I called an LG repairman and he was pretty certain that was what it was--capacitors. I'm going to have him come by tomorrow. By the way, the TV is about 5 or 6 years old.

Thank you so much! I will post confirmation of the diagnosis after his service call.

Don't ask me why I know about this.

And let's hope it's that since the repair is usually on the cheaper side of repairs.

Yes, that's exactly what it was!

He also said it's a common issue with LCD TV's, not just LG's, that are 4- 5 year old because the manufacturers cheapskate by using capacitors that are insulated for 10 volts and they eventually burn out. He replaced mine with capacitors insulated to 25 volts.

Thank you again for your insight and saving me a bundle. I thought I was going to have to buy a new TV!

Good to read, sad to read.

There is some misinformation about the Volts on the caps. The issue is a stolen formula, corporate espionage gone wrong and in the cases I encountered not one cap was the wrong voltage.

While it is fine to replace it with a higher voltage the same maker with the bad formula would still fail due to the botched formula.

All this is well discussed but the TV makers LG and others didn't blow it here. Unless you decide they should have done more research on the parts?
