BenQ LCD maintenance information


1 : BenQ LCD can switch planes normal (no signal light yellow, green signal), Looking carefully at the screen whether there are changes, they generally do not carefully read the screen can not see a change, oh, look at carefully Matata. Change or switch to a normal plane, the main board intact, such a high-pressure situation on board is no work, no lights lit backlight.

  • 1:明基液晶顯示器能否正常開關機(指示燈沒信號為黃色、有信號為綠色)、仔細看屏上是否有變化,一般不仔細看是看不到顯示屏有變化的哦,看仔細啦。有變化或能夠正常開關機,表示主板完好,這樣的情況就屬於高壓板沒工作,沒點亮背光燈。

    2:拆開機器,首先檢查高壓板(插220V的那塊板),螺絲鈕開,別偷懶,把電源板和主板都拆下,這樣比較好取下電源板、

    3:測量C5707、FQU11P06(有的機器是用FU9024的)、是否損壞(擊穿)、如果損壞(擊穿),將他拆下來,在看.22/160V電容外觀是否有變形,如果有變形請更換,如果電容沒變形就不管他。

    4:將損壞的器件更換新的,如果怕上電再燒,你可以講高壓線圈一起換掉,如果為了節約成本你就先不要換高壓線圈上電測試,如果在次損壞C5707就需要更換高壓線圈(大多數損壞C5707最歸禍首就是高壓線圈引起),

    5:測量高壓板供電部分是否短路,如果無短路,請將保險(PF801)換上新的(一般損壞C5707,保險肯定損壞),如果你手上沒有此保險你就用細銅線連接起來,此保險為3A。

    PF801請用電阻擋位測量,否則測量不准確。

We have a Benq FP767. when we start the moniter than the screen appear blank and blinking LED light near on/off switch. what i do?


Have you attempted to enter the on-screen menu system for the monitor? There should be a reset system reset option somewhere in the menu selections. If not give that a try.
Also you might want to check your monitor cable. Unplug then replug it in. If you still have a blank screen you might want to try the cable on another monitor if that's possible.

If the cable is not the problem then that leaves the monitor itself or the video card if your system is equipped with one. Check the back connectors and locate the video output plug. If it is located close to the keyboard, mouse, Ethernet and usb plugs it is what's known as on-board video. If it is located below those other plugs it is a video card. Shut your system off and disconnect the power cable. Open up your case and make sure that the video card is seated correctly. They can come loose.

Your only other option is to try your monitor on another system.
I really hope something here helps. Good luck

Monitor displays breifly then goes to blank screen


The green power light indicates that the monitor is receiving from the computer correctly. I suspect it is going into high voltage shutdown. There is a safety circuit that monitors the high voltage and shuts the monitor down if it sees anything amiss. So the monitor comes on and then shuts off. High voltage problems are generally not worth trying to repair. Another example of a worthless safety feature. High voltage failures are not dangerous, and adding the safety circuit just kills the unit when it may have some life left or worse, sometimes it is the shutdown circuit itself which fails!
Hope this helps.
