Question about Dynex DX-32L151A11 32-inch Flat Panel LCD HDTV - 720p - 300 cd/m2 - 16
How do we adjust the brightness on our tv, when all we see for a picture is a black screen? The sound works fine, but there is no picture when we turn the tv on. Can not get the menu to show on screen, either. Is this a "brightness/adjustment problem.....or possibly something else wrong with tv?
You need to replace the inverter board thats what preventing the backlights from lighting up so you can see the picture. You can get the inverter board from www.tvrepairworld.com

Unplug it from the wall, wait 2 minutes and plug it back in. if problem still exists, its probably the main pcb.

first check all componet wires in back make sure they are connected properly...if thats not it try reseting your color scheme thru your remote usually under the menu under picture or color and if thats not it it could be your bulb is going bad but try the first 2 things first

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc. Look for 5vdc, 12vdc, and 24dvc.
Please post back what you find.

If there is still about ? 24. Volts coming from the Power Board when it goes dark, it will be the Inverter board that needs replacing. If not, it is the Power Board that needs replacing. The Voltages should be written next to the sockets & plugs on the Power Board.
