Hi, if i press the power button to turn on the screen, for a split second the benq symble appears, then black. I have pulled apart the screen. it seems there are 3 faulty parts,printed beside these parts on the circuit board are the folowing C826, Q805, and PF801. I have taken the board to a local electronis shop and they don't have these parts, where can i get them and will they fix my problem once they are replaced. Thank you

Re: screen has power but is black
Looks like many faukty parts on the inverter board.. replacing will not be of much help as it will soon start get troublesome once again. I would suggest that replacing the LCD inverter board is a smarter solution. Hope this helps! Good Luck!

Press and hold the Home button for at least six seconds, until the application you were using quits.

on again. Press and hold the Sleep/Wake button on top of i Phone for a

1) Turn off the BenQ power, before connecting your VGA cable to the Toshiba laptop.
2) Once your laptop recognises the BenQ unit, you then need to tell your laptop to send an output signal to the BenQ - you do this by pressing your 'screen output' button (this is usually one of the function keys and you may need to hold the key for 1sec). The output function key can choose either single VGA output, or both laptop screen + VGA output.

We have a dis-assebly and repair guide posted on our web site at: www.ccl-la.com/monitor_repair.htm The problem is usually the driver transistors, our guide shows where they are and what to replace to get your monitor back running again.
Turn power on.
Press and hold the volume down button on the TV.
Press and hold the "split" button on the original remote.
Hold both for for over 5 seconds in power condition.
Counter will reset and lamp indicator will go out.
How old is the computer? Make sure that the power light comes onto the monitor when you plug it in, should be orange and then turn green when video card syncs with it when PC is turned on. If you are getting black screen when PC is powered on:
1. Bad video card
2. Bad video cable
3. Bad monitor
1Solution: Try using a different monitor attached to this same PC and see if it works. If it does, then its the monitor, its cable, or its power supply. If it doesn't work, then its the video card or the video cable coming from monitor.
Explicit enough to see that's this a a repair shop job. That also probably means a replacement- cost of which will not be much more than repair prices.
One thing how ever- the power supply[which would appear to be the problem] is this built into the screen [that is does the screen have mains power direct? Or is it powered from an external 'Power Brick'
If it is of the Power Brick type - then a new power supply is the answer - get on of the stabilized universal type with a fistful of connectors and a voltage selector switch.
