Gateway 900g no power

Hello,

The most common cause of power up issues with the Gateway FPD1960 monitor is a failure of the filter capacitors on the AIP-0100 power supply board in the unit. Here is a link to repair information for that board.

check at any other power socket or plug any other working equipment on the same wall socket to check if the power is ok in the wall socket
if all ok then either your power cord to the computer is not properly plugged in the computer or the computer power supply may not be working.
you may then require technical assistance of computer mechanic.

hi there.
not sure if this link will help you find them but have a look.
Fuses located on gateway 900g lcd monitor Google Search

Flickering could be a loose power connection but the hissing is indicative of a potential short. for your own safety, I'd get this to a TV type repairman asap.

the_princes, On the rear side of LCD screen that you look at are two each long, straight, cold-cathode-fluorescent-tubes that need to "LIGHT-UP"and provide pure WHITE light to be reflected through the LCD glass panel that you look at from the front side! If you don't have any luck with Gateway providing warranty service or doing a swapout with them, then you should possibly look into having it Refurbished by someone locally in your area. I highly recommend that you go to youtube and watch some video clips of LCD MONITOR REPAIR to see exactly what you are getting involved with. When making a post to tthis site you should always give some "history" along with the trouble "symptom" such as how old is unit and approximate total amount of "ON" time the unit has. I hope you can use the info provided. I'm louie12fix on fixya or [email protected] Bye for now.

try to turn it on the power switch on monitor.....and make sure all connection are ok

You can check the fuse on the monitor and replace it. In case the fuse is OK check the cable connector, display card on the motherboard.

Thanks

I'm writing this using a recently repaired Gateway 900g. You may be correct about the power supply, as that was the problem on this unit. There was absolutely no response with this unit. No blue LED, no dim display. Nothing.

WARNING: BE SURE TO UNPLUG THE AC LINE CORD. THE POWER SUPPLY HAS DANGEROUS 120 VAC PRESENT IF LEFT PLUGGED IN. If you don't know what you're doing, it's best not to attempt a repair!!!

Disassembly is a bit tricky, and there's a variety of different sized screws used; so keep track as you go. First you remove the front bezel (be careful as the two control boards on the lower right need to be disconnected). There are two screws (lower left and lower right) that secure the shell, the rest of the frame is just a snap fit around the perimeter.

Then remove the 6 screws that hold the LCD frame to the rear plastic shell. Careful here as well, as you must disconnect the back light cables AND the signal cable to separate the LCD from the Power Supply / Signal Processing board.

The Power Supply board mates to the Signal Processing board thru a 2x5 pin header. This contains convenient points to check the +12V and +5V supplies. In my case the +12V was OK, but the +5V was reading about +2.5V...not good! THIS IS REALLY DANGEROUS TO CHECK AS THE 120VAC IS ONLY AN INCH AWAY.

Here was the key symptom on my unit. Your's may not be the same. If I disconnect the Power Supply from the Signal Processing board, then the +12V and +5V read correctly (as well as the +16V that goes to the Backlight Inverter section).

However, once I connect the Signal Processing board, the +5V drops to +2.5V. However, the Signal Processing board seems to run correctly off of an external supply drawing about 300mA.

On closer inspection of the Power Supply board, I notice that 4 capacitors had buldging tops (domed). This indicated some stress. These were capacitors C205, C206 (470uF/25V) in the +16V section; and C210 (470uF/25V) and C209 (220uF/25V) both in the +5V section. I didn't have a Capacitance Meter handy, so it was simpler to just replace all four parts with similar values. (There's a lot of latitude in making these substitutions.) But be sure you have voltages a *least* greated than those needed; i.e. 16V or 5V. They used 25V to have plenty of headroom.

After replacing the 4 Capacitors, the Voltages and Blue LED responded normally. After reconnecting to the LCD assembly, all was well. Reverse the disassembly process, and you are ready to go.

Does the power button light up or blink at all ?
It probably is the power board/ inverter. I fix many of these.

To TeeKO, did you try moving it back to see if it was maybe a bad household receptical ?

If the on/off light is not lit, then the monitor is not receiving power for some reason.

This could be:

Power is not available, meaning the outlet maight be dead.

The power supply [power converter too, if it has a square/rectangular box as part of the powercord] for the monitor is bad, meaning it is getting power from the outlet, but nothing makes it to the monitor.

The power converter or cirucuit board in the monitor is bad nad needs to be replaced, because power is getting to the monitor, but the monitor is either not able to convert it into useable current, or the circuit board within the monitor is damaged.

You can find out which is going on by doing the following:

Grab a $10 voltmeter at your hardware store and check the power coming from your outlet, then plug the power cord/converter into the outlet and check the other end for same. Note: If your power cord has a converter on it, check to make sure the voltage/amps are the same as what is printed on the label of power converter. If those are all good, then your monitor needs repair. get a quote first before allowing any work to be done, as it could cost more to fix this than a new monitor would cost.
