But there was a company that made millions of bad caps. You can google BAD CAPS for the full story but I have yet to find what you wrote to be true.
Please remove the set from service and call it in. It may qualify for a capacitor change.
I have a Samsung LA40S81BTV, maybe 2.5 years old. The problem is that it takes anywhere from 15 mins to 2 hours to come on.
I have read on another forum that it is to do with capacitors that have been installed with voltage levels too low. The TV is out of warranty so anybody that could give some advice??
