Another Gateway 24" LCD works - Kinda

[itsparks]

I have a gateway 24" lcd the hd version with all the inputs etc etc, the FPD2585, it works ok untill you go and try to use a higher resolution, I can use the 1680x1050 some times but some times it starts flickering and getting all distorted etc, when i go the the max resolution it just goes all millions of lines and you can't do any thing with it, however i used to be able to do it on this setup.

At first i thought it was the video card so i bought a new one, installed drivers and still does the same thing, so i bought a different brand and make video card that has dvi and vga it still does it, however if i use component ( of course lower resolution on a dvd player ) it works fine.

What could be wrong, ? bad cap or main board ? I'm on it right now using 1400 x900 and its fine.

When its at the 1680-1050 resoltion its ok some times but when you click the touch buttons you can see it get all weird. If pictures & or movie help i can post.


Maybe ill just put it on ebay for 99$

What's the native resolution of the display?

Native resolution is what you want to use all the time. Going beyond the native resolution utilizes a scaler which downconverts the higher resolution to your display which always equals poorer picture quality.

If you're not selecting a resolution out of the monitors display range (which would cause all type of weird things on the display) it sounds like a problem on the main board with the video scaler.

The monitor will do alot of resolutions, the max resolution used to work just fine, then it started doing this, so i changed the resolution to a lower one, then i started again, the max resolution it can handle is 1600x1200 16:10 in its day it was a 1400$ because it has the tilt feature and all the extra inputs such as dvi vga composite svideo and 2 component.

I know im not hurting it or putting it into a resolution it won't handle / accept. I think its the video bard or something, is it fixable or ?

The monitor is in mint shape i could sell for parts, the back light is perfect its a bright lcd monitor, the lcd has no dead pixles. and it powers up and psu work, but not sure if i want to fix it, im not putting lots of money into it thats for sure.

Locate a 8 pin IC that says 24xxx and post back. Might swap it for blank EEPROM and let the firmware refill it with proper settings might help.

I had to do this to one generic monitor that corrupted a eeprom IC (24xxx) that it has trouble starting up.

HOw big is that chip ? Is it soldered to the board ?

Re: Another Gateway 24" LCD works - Kinda

tiny. No bigger than your pinkie nail. Usually SMD on the mainboard. It is near a one of chipsets. It will say like 24C08, 24C16 so on. For example and I thought monitor is already disassembled?

Eeproms are smaller than the main ICs most of the time they have a Revision sticker with the firmware version on them. It will be on the main video board.

I thought it might be one that was in a socket simular to bios eprom's, Where can i find a replacement ? Should this cure the problem ?

I know all about smd and soldering, have many soldering irons on my bench and i work with smd parts all day I build amplifiers and stuff.

Please post back when you find the 8 pin IC marking on it.

Gateway FPD2485W

>> Correct model number? Should be FPD2485W perhaps?

>> Answer to Krankshaft's native resolution question - 1920 x 1200

This could be a weak power supply. Higher res drawing more power and supply can't keep up.

Have you owned the monitor since new?
Was it always this way?
How long have you had the problem?
Was there an "event" that started this? (power surge, lightning, system failure, etc.)

Sometimes wrong refresh rate can screw these up. Trying to run 72Hz vs. 60Hz.

See Gateway chart for supported resolutions:
