Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!

My LG 22" flatron is with a G4 silver PowerMac and has been successful for about 3 years until yesterday when it showed message ANALOG Out of Range 111.4 kHz / 100 Hz Although there is a button that says...

this is common on all systems with monitors.
here is a fact for you,
not all PC/mac, etc, support all video modes.
nor do the monitors.
I boycott apple but it really is not any different that PC,
infact becomes more like one every day..(history)

the PC solution is to go into safe mode.
on the back of all my LCDs is a post it note,stating
the sweat spot. for horz x vertical, and refresh
the manual off all LCD states this sweet spot.
my sticker says 1920x1080 x 60 hz.
all monitors use 60hz refresh so start there.
do no use my above resolution, USE YOURS.

there you go , now all you need to do is find MAC safe mode.
and set the resolution back. to normal.
and can be very hard to do, when the screen is blank.!!

the monitor does not set the reso, the system does.
the monitor is telling you the system is sending ILLEGAL
signals. that is a fact.
im sure someone that used apple-sauce will answer.
or google it. (this will work, 100% sure)

I recently bought a new PC monitor and am planning on giving my Compaq monitor to my sister but cannot locate the manual or user's guide that came with it. Where on the Internet can I view/print a copy of...

try here:,,&target=productDoc&idDeviceType=2708&idMfg=1564&idProduct=475072

Although you don't need a manual, set the resolution on the computer to 1280 x 1024 and it will just work.
I hope I have been of help but please do not hesitate to ask if you have any further questions.
I appreciate your vote if you appreciate my reply.

Just bought this Flatron W2254TQ monitor. There's no 'ON' button. There's no power getting to the monitor. There are no lights. There is no message on the screen. There's no feasible way I can actually...

There is a power button if you have a real monitor - first make sure the AC power plug is securely connected to an outlet and the monitor and make sure your monitor cable is plugged securely into your computer. The power switch should be a small semi-circular groove on the lower right plastic casing of the monitor. Use this link to locate a manual if you don't have the manula that came with your product. This should help you locate the button

I know this is a guide to a different model, but the location of the buttons should be similar. Are you sure you typed the product model correctly, I wasn't able to pull up a manual for a w2254TQ. Again, the manual link above should help you.

Hope this helps FixYa! If you found this colution helpful, please share your positive feedback and a testimonial. Thank you for using for your support problems.
