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..

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.

For the monitor that is more than 2 years old, first place to look will be the power supply, look for bad caps with bulging top first, post back what you see inside so we can guide you further, see example of failed monitors due to bad caps; http://s807.photobucket.com/home/budm/allalbums

Blown power supply


If it's possible, install a small computer style fan and direct the air stream over the power supply. You should then get another 10 years out of it. Unit needs ventilation and cooling air. Hopefully, it isn't installed in tight quarters.

Benq FP71G+S NOt starting.


Hello
I have had this problem twice once at my school and once with my BenQ FP71G Monitor. At my school the monitor ( HP ) just stopped working and smelt like burnt popcorn.(though is think this is due to some kids chucking a soccer(football) ball at it! With my BenQ it has the same problem though i nownthink it is because of the monitor has been on for excessive hours ( 3-4 ) and just shut down because of overheating. I will see in a couple of hours if it works !

Hyundai LCD TV HLT 3010 Pictue suddenly turns black but has voice


This is quite a common problem on LCD televisions.
It is not a fault you can repair yourself unless you are a competent electronics engineer.

One of the transformers on the inverter board will be the cause as the tend to go open circuit. Being surface mounted adds to the dificulty of changing this item as well.
