Check the capacitors on the power supply if any on the secondary side are bulged replace them all with low ESR substitutes. Panasonic FC work well.

Also check the transistors around the inverter output transformers there are two on each side. Check them with the diode function of your DMM if any measure shorted replace both in the pair. You can find these on e-bay.

That is a power board / inverter assembly getting it would be extremely hard not to mention expensive.

Its a problem with the inverter. check the 4 transistors, C5707 near the connectors for the backlight. If none are defective, look for the PF751 FUSE. It sure to be busted.You can replace that with another 3A fuse. Remember, you should only replace the fuse if you are certain there are no busted transistors in the inverter board. Otherwise, you now have a refurbished Benq Monitor

SOURCE: balance CM2019 19" LCD monitor power supply, cord

I have this monitor currently and I ordered another one off ebay and I am also in search of another power supply for the one that I purchased. Since I alredy have one I know that the one that works with my current monitor is manufactured by a company in china called Linearty Electronics and this link: http://www.linearity.com.tw/EPmenu_LAD6019.html is to a spread sheet that list the model that was packaged with the 19" Balance Monitor. (or at least the one that came with my monitor). The model # for the power supply is LAD6019AC3 it's 15v DC 4A. The website gives no information about how to order it via them but they have a contact page that gives a sales email addy as well as hr and gen inquiries. I have sent an email today to see if they can direct me in the right direction to get a power supply for this monitor. Hint: If you got to the site you will have to change the language to english on the main page of the site since this company is a chinese company their site will automaticy come up in chinese except for the word english that the top that will convert the site to english. I will post another response if I hear back. I sent the email just a few minutes ago.

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

It may have the same bd as DELL since BenQ makes monitors for DELL and HP.

I have a BenQ FP71G+ 17 lcd monitor


When you have strange problem like this, first place to look will be the power supply section. Look for burnt parts, leaking/bulging caps, that will be the starting point.

On power on, screen comes to life for 1/10th sec, then dies. Power supply seems to be from Benq.


i just repaired a HP1955 monitor,the symptom was: when you power up the monitor,it shows on screen a desktop,but after a sec is screen going black..this repeats continously...

i just resoldered the AC cord connector on power board and also the impulse transformator...now the monitor is running good..

Contrast decreases to Zero


Had the same problem recently with a Benq FP71G+. It was still under warranty so I called customer care and they sent someone who replaced the board inside that contained all the buttons. I saw that the board was very easy to remove. He just unplugged it, and plugged in the new one. And its a very small board so probably doesn't cost much in case your monitor's warranty period has expired.

BenQ FP91G+ 19" LCD Monitor black screen


Possibly either the backlight lamp or its associated power supply has failed. Power buttons (mostly LEDs) have constant availability of low voltage (for some other circuits too) otherwise they wouldn't 'wake up' on command from a computer as some do.
The blackout could also be due to a failed main power supply so the incoming video is no longer being processed.

Benq FP71G+S NOt starting.


Hello
I have had this problem twice once at my school and once with my BenQ FP71G Monitor. At my school the monitor ( HP ) just stopped working and smelt like burnt popcorn.(though is think this is due to some kids chucking a soccer(football) ball at it! With my BenQ it has the same problem though i nownthink it is because of the monitor has been on for excessive hours ( 3-4 ) and just shut down because of overheating. I will see in a couple of hours if it works !
