Question about Televison & Video

1 Answer

We have a BenQ DV3750 LCD television. It is three years old, almost to the day. It has never given us any trouble to this point, but I went to turn it on the other night and it wouldn't come on. Upon further investigation, I realized that the red LED indicator light that tells you it is plugged in but not on, was not lit. No buttons work at all, no lights come on, no indication there is any power at all coming to the TV. I've tried unplugging it and plugging it back in, but to no avail. It just appears that there is no power at all. I called BenQ, and all I got was "send it in at your own expense (both ways) and we'll quote you for $65 on how much it will cost for us to fix it." I'd rather buy a new TV than send it off for a blank cheque, but if you have any possible solutions, that would be great.

It has happened because the power circuit of your TV has gone bad, if you have opened your TV before and/or understands the risks involved while repairing a TV set then please check for the power transformer on the TV board. There might be chances that this happened because of a loose connector inside the TV set or due to leaky/faulty capacitors. I would suggest you check for the connections on the power circuit board using a multimeter. Also try to see if you find any burned components on the circuit board.

Please do accept this solution and revert for further assistance.

Benq LCD Tv Dv3750 PSU model FSP 320-6F01

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..

Please rate..

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.

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.
