Question about BenQ FP71G 17" LCD Monitor

1 Answer

My BenQ FP71G powers on and off, repeatedly, by itself no matter whether connected to computer or not. Everything else is fine. Sometimes it stays on for a minute or so, but usually for just a few seconds. It is only just over 3 years old. It has twice been in and out of repair shop. After first time, stayed on for 36 hours before fault recurred. This time I only get up to several seconds of "on". Repairman claims to have replaced PC board and on/off switch. In Malta, using 240V AC mains power.

My BenQ FP71G 17 in goes on after hundreds of times pushing on off switch and when it's on it does not go off, I have checked the on/off switch which is working oke and when the moniter is on the auto adjust message (brightness and contrast)pops up frequently and the screen adjusts itself.

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.

Benq screen shuts down when pc is plugged in


If it's a 71g and not 71g+ resolder transistors 2sc5707 on invertor board along with grey condensers and inverter transformer.This should solve the problem if it was display shutting off with power led remaining on.Otherwise check power section.

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 !
