Faults & possible causes to LCD & Plasma screen are given with illustrations. You can get an idea about the fault to an extent. Faults to all LCD & Plasma screen are similar, irrespective of its brand and screen size.
Unfortunately, you fried the HDMI controller. Not necessarily part of the power supply "main board." (Not sure which board is the HDMI controller in your specific TV. It's usually a separate board by itself). Easiest workaround is to use the "Component" cable connectors. The downside is you only get 720P. However, most cable/satellite and _all_ antenna signals are only 720P anyway. Most people only see 1080P when viewing Blu-Ray discs. Aside from replacing the HDMI controller, the cheapest workaround for multiple source connections is to buy an HDMI to Component Converter A/V box, which allows you to connect multiple devices to one box with one set of Component cables connecting to the TV. Then select various "sources" via the box.
Check whether the audio is muted by accidental press at remote control button. Enter its sound menu, and check it. If muted, as you know there will be no audio output. If not muted, check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis.

its better if you replace the whole power supply board rather than replace the burnt surface mount parts because commonly if the surface mount parts burnt out there are some shorted parts that cause that burnt and possibly repeat the problem..
Hello There are two main reasons for this fault. If the CCFL lamps emits less light, due to long time of use. The second one is with the t'Von board [Timing Control Board]. You haven't given the exact model number of your BenQ TV here. If so, I might send the pictures of these components. OK.
I have the exact same part burned at the bottom. I just used a long nose plier and bend the bottom so it touches the print board circuit. It works. I guess I could also use a soldering iron to fix it. But will see if this temp solution works or not.
No lamp on LCD tv.The LCD backlight inverter board it dead,that board needed replaced to get picture back.Tries Shopjimmy.com,Ebay.com to buy the LCD backlight inverter board.It usally a long board.The refurbish LCD backlight inverter board about $100-$120.
Most of the time it is the Main Board in the TV that the sensor plugs into. They have had many issues with this Board causing this problem. To be sure, you will need to call a professional.
Hope this helps,
