Good afternoon I have a Sony Bravia model KDL-40M4000, when I turn it on it stay blue and without audio what can be the problem Can it be the main board or the LCD board Best regards Eugene


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ 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.

I have a Sony TV model KDL-40BX412. There is a red ghost. Sometimes it is green. The longer the TV is on, the distance between the image and the ghost decreases, but never disappears.

Normal picture mode make the sharper picture quality but smaller screen apparance


If the broadcast is in 4:3 (square) then either you can have the black bars on the side, or the TV can stretch the image to fill the screen.
Nothing wrong with your set. The broadcast must be in 16:9 to fil the screen.
