90559 2002-10-18 20:24:00 I recently moved to a new address, and in the process my monitor, a compaq MV540, has probably been knocked and as a result the image on it is now skewered. I have tried re-adjusting it through the settings menu inbuilt in the monitor itself, and although I succeeded in straighten it up a bit, the problem is still there and it seems to be residing with some of the elements inside the monitor (or so one technician said).
In essence the problem could be fixed no problem but at a very high cost!
I could send the monitor away and pay a fixed $200 dollars minimum for it to be repaired.....And that doesn't include parts. I would like to know whether there is anything that could be done in a way that wouldn't break my bank acc. and my marriage, for I really like my monitor and it is only 1 and a half years old.

90560 2002-10-18 21:12:00 Try looking at our Billy's brand new monitor FAQs. They're so new they aren't even in with the other FAQs yet (link top right of this page).

Have a look here (pressf1.co.nz) and here (pressf1.co.nz) and hopefully something in them might be of some help. :-)

90562 2002-10-18 21:58:00 HI, I had the same prob with my monitor (out of waranty). I dropped it, and now it has a slight keystone shape, but tipped on its side (ie the keystone adjustment function narrows and widens the image top and bottom, where my screen needs to have the height of the right side of the screen increased relative to the left side.

I was also told it was anexpensive fix. I can put up with mine, but you might want to pisck up a working second hand one to replace yours if it is very bad.

90563 2002-10-18 22:56:00 Thank you guys, you all have been very helpful and alas no easy solution appears to be available, some others seem to have a reasonable viability.
Always great help from this forum. Keep it up guys.
Thanks again.

90564 2002-10-19 02:48:00 Hi Sanco

I can't quite grasp what your problem is, but if you think the pix is tilted, it may be that the scan coils have shifted. If the top of the screen image slopes down on one side or the other and the same slope exists at the bottom I would take it to a TV repair shop. It will cost a lot less than $200 to straighten that up. Alternatively, if you are handy with a screwdriver you can tale the back off and see if the scan coils are loose. they sit on the neck of the CRT and extend up over the bell.

As in my monitor FAQ, you will have to unplug etc to work safely and some metal covers may have to be removed to get access. If they are loose, twist them straight and make sure thay are seated firmly against the bell of the CRT then once the screen image is level, tighten the securing screw (if it has one, some may be simply glued so use a hot glue gun).

If the top and bottom slope in opposite directions, this is called horizontal keystoning and is an electronic adjustment. The equivalent effect for the sides of the image is called vertical keystoning and is also adjustable. Check your monitor manual or on=screen menu.

I'll stop here and if you can post a better description of the effect we can pursue further options.

Cheers

90565 2002-10-19 04:54:00 Billy, I have what you call horizontal keystoning, but my on-screen display can only correct for vertical keystoning. Is there any way I can fix this???

90566 2002-10-19 06:59:00 Hi Graham

Are you absolutely sure that your OSD doesn't offer horizontal keystone adjustments? It would be most extraordinary to find a modern monitor of reputable manufacture that didn't .

I suppose it is possible that it is a manual adjustment internally but that would be quite unusual . Can you post your monitor brand & model number and I'll see what I can find out .

You may need to look at the serial number area to get the technical model number as the info on the front is often just a marketing designation . If you have a paper or CD manual check through that as well, just in case .

Cheers

90567 2002-10-19 20:56:00 Hi Billy, I have opened the back of the monitor, as you said, and following your instructions I have checked that nothing was skewered or twisted.
Well everything would seem to be fairly straight, as far as I can say, and more importantly, everything that was glued had not moved from the factory positioning. One thing I have noticed though, on the neck of the tube there are two one inch long 3 millimitres thick little blackish bars, like those ones you would find in radios for example, sitting on either side of the tube, glued on. Well only one is still there whilst the other is missing and I can definitely say there was one there, for there is still broken glue sitting there. How important are those bars and could that be the reason for the image to be very out of tilt? Finally to answer your question, the image on the mon. is twisted to the right. To give you an example, imagine looking at a painting on a wall that is not sitting straight, in fact I can move the image but the black frame around it will always stay the same, with the result of loss of image on one corner or another depending on how I adjust the image itself. You seem to be on to it and I am not scared of getting inside the monitor, so let's see if we can toghether solve this little mystery. Finally thank you ever so much for your help so far offered to me, I really appreciate it.

90568 2002-10-19 22:35:00 Billy, thanks for the help. My keystoning prob is fairly minor, and definitely bearable, but I have uploaded a pic (knightguider.orcon.net.nz) from the manual for you to look at. The monitor is a Likom L7034LD.

Cheers
