Your power supply/inverter board has died. Heat buildup in lcd monitor cases cause parts called capacitors to overheat and blow out. If you can solder you should be able to do the repair yourself. Check out the pictures on our web site at: now open the back of your monitor and look at the power board, replace all of the blown capacitors that yousee and you should be back in business. Be sure to use high temp caps, they will be marked 105c. Also be sure to insert the new ones with the polarity stripegoing the same direction as the ld ones come out. The values you need to purchase will be marked on the sides of the blown ones you take out such as 220uf, 470uf or 1000uf. The replacements can be ordered from many places on the internet or we can supply them for you. The capacitors at Radio Shack will not work, they are not rated low ESR and high heat so they will blow out in a month or two. If you don't want to do the repair yourself we do offer a repair service for $35 + return shipping.

I hope this helps, if so please rate our solution.

Camera does not come on

Make sure to remove the battery first ... make sur your camera has a full battery charge ... then select "MENU" scroll through options until you find "FORMAT". This will re-set all your settings back to factory settings ... you will lose any saved pictures on the internal memory only. ALSO when your camera light goes on try to hit the PREVIEW OR EDIT SElection. I* cant see how the memory card being removed would cause your display to permently be damaged. You can also try to connect your USB/AV port. Use your A/V cable with the two input connections to a TV to see if it is putting out an image. Hope all goes well

Hi My Benq FP91G flickers with the auto syncing message around once every 60s. sometimes the power button does not work, i have to keep pressing it before it will eventually switch on. Is this worth...

Its worth fixing...
Its just an issue with the board.
If it happens to be the LCD panel, rather not fix it since its gonna cost u a fortune.
