Hi everybody!

I've got a Compaq Armada 1750 notebook which is now about 3 years old. No more warranty. Sometimes the display starts to flicker. This grows from some ignorable annoyances until nothing can be seen anymore (just a plain backlit white screen).
We had the same problem with several of these notebooks in our company.
As you can think, giving it to Compaq for repair means exchange display and/or motherboard, pay thousands of Swiss Franks, and therefore is inacceptable for such an old (though still useful) item.
Has anybody had similar problems? And knows whether (how) someone with quite good technical skills (not necessarily me!) could approach the problem?

Martin,

I don't know what kind of actual presence they have in Switzerland, but here in the U.S. you can have repair work done by an authorized Compaq repair shop instead of actually sending the hardware back to Compaq.

Check to see if this is an option. If so, give them one to fix and see if they're able to do it.

You may also want to try and use the notebook attached to a monitor for a preiod of time to determine if the problem is system board related or display related.

If the unit works without difficulties when a monitor is plugged in, you need to get a replacement display. If the monitor solution does not work then their is some other underlying problem and it is likely not worth the repair.

Even if it is a display, it probably isn't worth the cost to replace it. You would be better suited to use it as a low end desktop at that point ( with the monitor attached).

We have an Armada 1710 with the same problem and it does appear it is just the display in our case.

I also have a Compaq Armada 1700 with this problem. Today I asked the service partner of Compaq, and they told me that this is a problem of some connection between the motherboard and the TFT monitor. You can also visit this web site where somebody is discussing this problem and found an similar solution.
Look at http://home.netvigator.com/~altimate/mycompu.htm

I will try to solve this problem myself, and if will post if it works!

I have had same problem with a number of Armada 1750's when I contacted Compaq I was told that it was a problem they knew of and that they would extend all warranty and replace system board free of charge. CONTACT THEM YOU NEVER KNOW

How long did they extend the warranty for you? I'm on the phone with compaq ts and they insist that they will only extend the warranty 1 year beyond the original warranty. If I get any new news, I'll repost.
FYI: 1750

I have been having the same problem (Armada 1750). I too contacted Compaq who can only extend the warranty by 1 year. I think this is ridiculous since the machine is older than that and obviously alot of people are having the same problem (Compaq forums).
Despite this I asked how much it would cost (UK). They wouldn't quote a price until they tested it. Again ridiculous since they know what the problem is (connection problem between mainboard and audio device apparently, mainboard needs replaced). It would then cost £75 for the quote if not accepted otherwise the cost of fixing it.
If anyone has anything different please let me know. I will repost once I have any further news.

Not much new to say really. Compaq was brickwall stern about the fact that the warranty would only be extended a year beyond original warranty. I spoke with a "manager" in customer service to no avail. I tried to explain to him a like situation in the auto industry--paralleling this display problem as a kind of "recall" but he (from the beginning) was not interested in listening to these thoughts. Hate to say it--but it really seems like a dead end. Unless of course their customer service department takes on a new philosophy of customer service. I wonder what other tech companies are doing...

I've repaired many of compaq's laptops over the years. Normally, reseating the boards will help this problem. There is an I/O board that one of the two cables that comes out of the display unit itself plugs into. This is the same board that has the little button in the upper left corner of the machine that detects if the screen is closed or not. This tends to be the problem and the board needs reseated. The biggest problem is that if you aren't familiar with taking laptops apart, then it can be difficult getting it all back together without damaging anything. If you are so daring to do this, make a diagram of where all the screws are located and make sure you grounded yourself. Other solutions are to just press that little button that I refered to, this resets the screen so to speak and sometimes temporarily clears up the problem. Most of the laptops are very notorious for the screws becoming loose in them and problems like this develop. Probably not enough of their blue-goo on the screws. The more travelling you do, the quicker things become loose.

As for the warranty issue, they came out of the factory with a one year warranty. Compaq itself allowed an extention of another 2 years for $200+ for 2 additional years in the US. Most of the manufacturers though changed the rules for the extension on the machines in foreign countries. Depending on the country, they allowed a 1 or 2 year extensions if any at all.

Hope this helps

Hey,
I have a Compaq 1800T and it also has the flickering & Blinking screen. I spoke with a laptop tech, Compaq, and just about everyone else under the sun about the screen problem. I've found it best when the problem first starts I partially close the screen until the screen goes off then open it and it usually doesn't give me any more problems. Although I did speak with a guy that was very familiar with compaqs and he said he didn't have any problems with his compaqs until he installed XP on them. Mine came with it. I hope that works for you

I had a look at a Compaq Armada 1750 (1 of 3) , it has 3 bars on the lcd where there is no picture. (the bars change color ramdomly)

The external vga port on the laptop has no problem, so the problem is with the lcd panel. Have checked cables and connectors, and shaking the screen does result in the bars changing color.

I beleive it is the voltage unit inside the panel, but have not taken one from a working laptop to confirm this.

Regards

~~~~~~~~~~~~~~Found and Awnser!~~~~~~~~~~~~~~~~~~~
Hey, I've got an 1800 model and it HAD the flickering screen. I tried talking to a Compaq tech, calling compaq countless times and I got tired of dealing with those pinheads so I took matters into my own hands. I took a small screwdriver and took my laptop apart and carefully kept track of all my pieces and I disconnected the screen completely. Then I re connected it. And put it all back together. The whole process took about 2+ hours but I've NEVER had the problem since and it's been 2 months. If all else fails and you have a tiny screw driver try that. I highly recommend it. I hope it works for you. The hardest part was keeping all the screws organized. Good Luck!

after reading all the suggestions above i actually opened my laptop apart which took me about 30 min. by the way i never opened a loptop before. and just put it back without doing anything and next time i turn it on and play games it seems to work fine. till now i didnt have any problems. didnt even had to use the reset buttons. i suggest opening the laptop and shaking it or doing some thing that you may want but be careful. it solved my problem. it is worth opening as it is an old laptop it is worth trying it.

>> Re: Compaq Armada 1750 display problems -Before you disassemble the whole thing...
I experienced the same problems after dusting off the ole 1750 and taking her out on the road quite a bit lately. It seemed after she warmed up, the screen would go white - and the reset button was useful only intermittently.

You may not need to disassemble the entire case to fix the problem - The Armada 1750 has a large bezel over the left screen hinge (near the screen button). Remove the one screw that holds this bezel in place (it's on the back). You'll need to open the screen up to about 160 degrees (almost flat) to remove the bezel.

Under the bezel (on the keyboard side) are two plugs for the screen. Make sure the one on the left (black) is seated (press it down), and then remove and replace the one on the right (white). DO NOT PULL ON THE WIRE(S) TO REMOVE THE PLUGS - use a tool (I used a really really really really...really small screwdriver to pry up (walk it out) the white plug. The black one refused to come out and I didn't want to force it since it looks as though it's plugged into a card that plugs into the motherboard.

Then simply replace the plug and replace the bezel. And wah -ah, screen works fine now. (hope it works for you).

There shouldn't be a need to take apart the entire case.

Good luck.

I guess my conclusion was a little to fast, beacuse now the problem is back. I tried to disassemble the laptop, but I didnīt manage to remove the keyboard. Does anyone know how to do that?

The other solution for the white screen problem is to unplug all power, including battery (or batteries if you have the second one in) then with a ballpoint pen or tiny screw driver unlock the keyboard via the two small tabs at the below the space bar. Lift the keyboard up and you will see a white plug on the right with two tiny wires... the bios jumper. Unplug it for 5 to 10 seconds, reconnect, snap keyboard back in (top first), reconnect power and you should be fine. This does not stop this from happening again, but I don't know what will...

There is a more complex albeit, easier fix for the 'black screen' problem. I had it, fixed mine about a year ago and now can't find the fix. It involves going into the setup I think... if anyone know? Please post?

Thanks!

I have a solution that will fix the problem for 6 months to a year for most of you but you will then have to repeat. The problem is that Compaq went cheap when they built this machine and they used silver for the connector pins instead of gold. If you know anything about silver you will know that over time silver becomes oxidized. This is why after reseating the connection for the display plug will solve the problem for a short time. To fix you need to unplug the power and remove the battery from the system. Make sure there is no power going through the system or you could fry your system board. Now remove the cover on the left that covers the two connectors for the display. The black small one is the power and the white one is the output from the video card to the display. Go out and purchase some silver cleaner and a small paint brush (like what you would use to pain model cars) this should be small enough to do the job and you should not be able to bend any pins. Do not use a q-tip or anything of that nature, you may bend the pins and if you break one you are screwed. Simply dip the brush in the cleaner and run it back and forth over the pins. Donít have a whole lot of cleaner on the brush you donít want to get it too wet. Now re-seat the white connector and take it back off, repeat this a few times to work the cleaner up and down the pins. Remove the connector, let everything dry over night and then reconnect the connector and put everything back the way it was. I have done this on two armada 1750s and it fixed them both for about 6 months and then I had to repeat to get another 6 months. There really isnít a permanent fix other then using an external monitor.

This is very disturbing problem with the Armada 1700's and 1750's. I have read many posts on this and feel that this may only

be a mechanical hardware problem.

I have suspected for some time the contacts between the LCD and the mother board. These are the white and black connectors

just under the left hinge cover.

I have heard about oxidation buildup on these connectors causing the screen to "white-out." This comes from a faulty

connection with the WHITE connector. The Black connector is for the inverter for the back light.

I decided to CLEAN these contacts on the WHITE connector by purchasing some Tarn-X (tarnish remover and silver polish) from a

local drug store. First I powered the computer off and remove the battery. I dipped the WHITE connector into a small tray of

Tarn-X after I unplugged it from its motherboard socket. I let it soak only for 30 seconds and then removed the Tarn-X and

then dipped the same WHITE connector into water as a rinse. After a few seconds of water I used canned-air to blow out all

water from the connector and then allow it to dry for a half day. All this in taking care NOT to get any solution into the

computer because it would ruin it! If you want to be super cautious remove the entire LCD with its bezel from the base before

you attempt any of this.

After all is dry I plugged in the white connector and my display has been rock solid ever since!! Even a little brighter, I

think.

NOTE: I only cleaned the white connector, however, it wouldn't hurt for the black connector to be cleaned too. DO NOT put any

solutions into the socket (pins) of the motherboard. The Tarn-X will short out signals between the pins with it residue.

Thats why we rinse with water and then air dry.

Let me know how yours works out! It won't hurt anything to try it.

Hi, ive been reading up about the 1750's display problem with the white out but i actually have a black out problem. After pulling the laptop out of retirement a week ago and loading XP on it the screen began to flicker similar to what has already been described. Then during a 3D game it just went black. Now when you reboot the laptop the compaq logo comes up and then the screen goes black even though you can see there is still power to it. Do you think this also has to do with the LCD connector plugs? As the compaq logo is perfect, just nothing comes up after it. Im going to try some of whats been sugested already but any other help would be much appreciated.
