It's been 2 years since I've repaired this Samsung P277HD TV with a bad inverter transformer. I use this TV as a computer monitor. It is now exhibiting a problem with the brightness control. I would set the display to "text" or "internet" which is a dimmer setting than "entertain". About a half hour later, the screen would go max brightness back to "entertain" mode. I've even manually set the brightness to 40 or so and 20 to 30 minutes later it's back to 100. I think the power supply chopper circuit is failing.
What do you think? Has anyone ever experienced this problem?
