BenQ FP767 17" LCD Monitor Problem - Power LED Blinks

Dear Viziks,

I am having this problem with one of my BenQ FP676. The Power LED blinks / no image (backlight off) although I can see something being displayed when using a flashlight (image also blinks in the same frequency of the power LED).

The fuse is OK, of course (I have checked)

I have tried to find the schematics online but was unsuccessful. I wanna test the transistors, but (to be sincere) I am lost on this board. Do you have any hints to find the schematics online?

I'd really appreciate your help.

Regards,

RC

Look for small power transistors 2SC5707 near yellow invertor transformers which go to backlight connectors.
But if problem is blinking power LED powersupply capacitors maybe an issue,check visualy and/or replacement.
Also fuse that maybe blown is not glass fuse near mains socket,It is semiconductor black or yellow colour labeled PFxxx near heatsinks of power supply secondary.

Please rate the solution and provide feedback.

Power not on, power button blinks green power light, doesn't power up. Benq FP92W


It sounds like you have a power supply problem and the safety shutdown has kicked in, the system will need to be checked by a computer tech with an estimate in mind.

LED blinks in milli seconds and the images appear too late.


If your lcd comes with ac adapter open this and check for blown or bulge capacitors, replace this with same value.

If your monitor comes with plug cable, open your monitor (too risky to do it by yourself) check the power supply section, check and replace blown and bulge caps.

Benq 567s lcd monitor does not power up. Switch led blinks but goes dead. Tried replacing capacitor 450v 82uf with 400v 100 uf but did not work. please help.


That cap is for the Primary power supply switching circuits. How is the DC secondary side, no blown fuse, shorted transistors in the inverter circuits? Pictures will help, budmrtn@aol.com

Power led blinks


Some of the capacitors inside off the monitor might be starting to go bad. If you can get the back off of the monitor, look on either the power board or the main board and you might see some capacitors that are getting puffy. The silver tops will look pregnant.

If you look in there and you don't see any puffy capacitors then you'll have to wait until the power led light blinks and you get no video.

If you look in there and see puffy caps, then replace them with capacitors with the same UF rating and either the same volts or higher.

Monitor to black, power LED blinks, hard re-boot and it works


Take a look at your power saving settings. It sounds like the monitor is set to sleep after 20 or 30 minutes. You may want to change your setting to "never". The settings are under Control Panel - Power management
