    Has anybody found a solution for this. I have replaced the Main board and the video interface board. Still has gray screen. It doesn't make sense that the LCD panel would be out. Please help

This Samsung LN-R408D TV has a small surface mounted fuse that has failed on the T-conn board (the small circuit board at the top center of the LCD panel as viewed from the rear)

The fuse is mounted slightly above the LVDS cable connector and the component marking next to the part may begin with a "F". Replacing the fuse with another fuse, or a thin wire filament, or a jumper will restore full functionality to this TV.

Try unhooking the LVDS cable from the controller board and see if it does the same thing. If so you need to replace the LCD panel.

I was using my Samsung LCD 40" - LE40M86BD [R] when it just switched off and wouldn't come back on. What could it be? Thanks guys


Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. . If you wish to get some details; check the site linked here. Pull up older posts.
http://electro-medical.blogspot.com/It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
