E172fpt Backlight flicker

HI Ray....unhook the plug going from the power to main board and see if you get backlights when you plug the set in, if you do chances are you have a bad replacement main

Hi,
Please check it monitor color adjust button. If ok then you check it monitor cable if change possible then change it or power cable also proper connect. If not solved contact Good Monitor technician.

Thanks.

I agree that the problem is most likely on the inverter board. I repaired a Vizio 42" LCD with the same problem, it was bad capacitors on both inverters. Cost $2 to repair. Take off the back cover to the set and check the capacitors on both boards. If they have bulging tops, that's your problem.

try re-setting the phone to factory settings or update the firmware to the newest version available, sounds like a software issue to me

Do a factory reset to this set. Refer its user manual for details.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

Not really, the screen flickering is due to a faulty circuit inside of the Mp3 player. If you have another one, you might be able to swap out the screen circuits, adn fix it, but this is very difficult.

I can help if anyone with this problem lives in Anaheim CA.
