Why does my gateway fpd2185w monitor screen go black after showing my desktop for about 1 minute

That problem is calle,refresh, thats happend when the monitor try to refresh the page or "clean" the page, you can set that in your video driver options. but if you don't have a video driver for your particular video card already installed, you don't have a right refresh rate and this delay, may happend.

I have an hp w1907 monitor i start up puter and after about 15 miniuts the monitor goes black i turn the monitor off and about 5 minutes later i turn it back on and works fine for about another 15 minutes


You could have a faulty inverter board. The inverter supplies high voltage to the CCFL lamp/s, these lamps are mini fluro tubes approx 1,5mm dia. and the length of the screen.
Check the inverter output/inverter board and you maybe able to get parts from

Monitor image comes up, then blacks out, power still on


Hello David,

This is very common problem and is heat/age related, but It can happen to monitors that are no more than a year old. It is usually bad capacitors on on power inverter board. I just fixed two monitors with this problem. This problem is common across all brands. Look for several radial capacitors in a cluster on the power inverter board. If some are bulging or have a slightly domed top, they are the ones that are bad. I usually replace all the capacitors in this small cluster because some may be marginal. This is easy to do if you have a bit of electronics skill.

LCD Screen problem


You have a failed inverter circuit. This is a very common fault with BenQ and other LCD monitors. I have seen more FP737 and FP731's and all their cousins in the last 2 years then I care to count.

You will be best to take it to a TV technician and have them do the repair. There are ways to fix it yourself, but the chances of success are not great without a decent amount of electronic knowledge.

Call several places and get approx quotes based on the inverter fault. A lot of TV techs will not work on LCD monitors and is another good reason to call around first.

One final thing, check the manufacture date on the back of the monitor, these normally come with a 3 year warranty and it will be either expired now, or very close to it. If it is still under warranty, then contact BenQ near you to facilitate the repairs.

PC or monitor, signal problems


your monitor is telling you it's on it's last legs..either that or your compaq has a bad video section. either is more vital than a video cable being loose.
