Question about BenQ T701 TFT 17" LCD Monitor

1 Answer

LCD flicks on for a second, and then switches off

I have seen other posts about this problem specifically with this brand of monitor, but was unable to find an answer. When I press the On button, whether its connected to a computer or not, it flicks on (I see BenQ symbol) and then flicks off. If I login to windows with another monitor, and then plug it in, it flicks on for a second and i see windows...and then flicks off again. Any help would be greatly appreciated... Pat

The screen goes blank after 1 second display, flicks back again to the display for 1 second and back to blank, this goes on non stop. The little led next to the on/off button goes from green to yellow...

pandres, Your monitor will need troubleshooting to find out reason why the 2 "cold-cathode-fluorescent-lamps" fail to remain lighted. They provide "white light" so you can see what is on the lcd panel. Connect a "known good" monitor to your pc to prove monitor is bad. If pc is ok, then your monitor will need repair. This type problem not new and is very common for all brands of ccfl back-lit lcd monitors. Watch some video clips at YOUTUBE that show disassembly and repair of ccfl lcd monitors.

Monitor goes black on bootup,when switched off then on again p image is seen for a second or two then goes black again

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for:

The amptron monitor will flick on for a split-second (long enough for me to momentarily see the desktop) with the center power (green light) lit...for a split-second. then its off for a few (3-5) seconds....

90% of the failed LCD monitors are due to bad capacitors (bulging top/seal, or leaking) in the power supply, or bad solder joints, etc.. You can look for them first. Please see the pictures here to see what to look for:

Had to reinstall xp after virus infection and now unable to change size, stuck on 640 x800

You need to download the specific video drivers for your computer. Windows only includes generic drivers. Go online to support.(my computer brand - insert your brand here).com and follow the manufacturers instructions for downloading drivers. While there I would suggest downloading all the drivers possible for your brand of computer. By the way - don't pay for the drivers, nearly all are free. Good luck

The power button flicks on and off and I have checked all my hookups, plugs ins and they all seem to be in working order

If you mean the on light goes dim, then I've had the same problem - unplug both computer and monitor - hold power button for monitor for 15-30 seconds...then power it back on and then power on the computer. Seems from other sites there is a power issue with the monitor - this worked for me.

AOC LM700 17" LCD Screen switches to black and then comes back to normal. Power light never goes green but monitor works. LED is orange when off and in sleep mode, wakes correctly on getting input. Just...


According to LCDParts, an inverter for an AOC LM700 would cost $69.99. Specs (with picture) are available here.

Perhaps you can do a Google for lesser priced versions.

Good luck and kind regards.

LCD Monitor blacks in and out for 1-2 seconds

does your monitor have an external transformer as the psu ?
If so, try disconnecting at mains for about 5 seconds and re-connect. failing that we'll need to dig deeper.

Philps LCD Monitor Won't turn on Straight away

That is definitely a problem with the monitor...if its under warranty have it replaced...if not...start looking for a replacement it hardly ever is worth it to have them repaired (shipping, parts, labor is usually a little less than a new monitor). Sorry
