Image collapses to a bright white horizontal iline

When monitor hasinitially turned on (ie mornings) the image be fine for a short period of time, then it starts to flicker and jump and then collapses to a bright white horizontal iline, Turning of using front power buttonf and back on will restore image for 2-3minutes then collapses again. Off then on again and I'm good until the next time I have to turn the monitor back on after it's been shut down for awhile.

    Ccreen colapses into brilliant white line. Smacking console or turning off and on provides temporary fix.

I resolve this problem this way.
In first about source of the problem - the solder in some contact destroy during some time (2-2.5 year) through temperature conditions. In result lost contact and award as a bright white line (some minutes and good bye, tube!).
I second - how I decide problem.
Please, see this picture - http://img165.imageshack.us/img165/3280/crw7783sc3.jpg
You see problem areas inside red circle.
I don't open the monitor (this is very difficult), but it age about 4 year and it out of guarantee.
I hack the bottom of the monitor -

and solder this contacts again. (This photo show back side of monitor)
After I try restore hole's edges...
Now my monitor shows without problems!

    I used electrician snips to cut the case open. Resoldered the joints and the LaCie is again working properly.

I've been fixing it the "rought" way (like skidog) for far too long...

Btw, temperature helps, so if you're reluctant to get it to a repairman or resoldering the contacts yourself, try covering the top ventilation with a heavy cloth after turning it on - it helps speed up the process. Don't leave the cloth for too long though - monitor might overheat or the cloth catch fire.

Also, don't beat it on the top, it can lead to short-circuiting and possible severe damage. Beat it on a front lower corner.

This solution was semi-proposed by the post by "noone", who's suggestion is certainly the route people should take if they don't want to risk opening their monitor and getting electrocuted. For those adventerous among you, here are the steps I took to finding the bad solder joint in my monitor, and fixing it! (no more blindingly white line across MY Lacie!)

Getting into the case is tough, as the plastic casing is held on by internal clips as well as the screws. (my version of the screen is an "electron19blueIV") The two screws are located at the rear, bottom corners of the display. Once removed, the case still won't want to budge. I actually cracked mine a little tugging it apart, which is why I'm spending so much time describing this seemingly simple step. on the seam that runs along the top of the monitor when in its normal viewing position, there are three plastic clips that extend from the perforated cover into the square rim that runs around the glass display: one clip in the middle, and one clip on each side, about 2.5 inches from the edge of the monitor. Sticking a screwdriver or a stiff putty knife in and levering should help you open them up. (screwdrivers are pretty thick for this, and will probably mar the surface of your monitor, I'd try to find something thinner.) That should be all thats holding your cover on. With the clips released and the screws removed, the cover will slide directly away from the front of the display. You might have to tug pretty hard. I put the whole thing down on the floor with a shirt laid out underneath to avoid scratching the glass, and lifted straight up, using a screwdriver inserted into the cooling slots on the bottom of the cover to pull up.

Now unscrew all the screws holding on the tin-foil-ish shielding covering the electronics. Once uncovered, you'll notice that there are quite a bit of wires/circuits attatched to the back of the glass cone of the monitor (thats the crt gun circutry). Running from that to the main board which sits at the bottom of the monitor are some wires. The wires we are interested in are bundled all togetherand are colored red/blue/green/yellow. They attatch to the main board at a white connector (a P1 i believe it is, for the techies out there). The wires that had the bad connection for me were the yellow and green wires, but I resoldered all of them just to be sure. Resoldering requires removing the protective backing, and is pretty rough. there are three screws on each side of the circuit board that need to be removed, as well as two or three screws scattered through the middle of the board. (you can tell exactly where those are by the imbedded hexes that they screw into on the back of the protective metal backing). to make it easier, I pulled a couple of the connecting cables off the boards in order to poke my screwdriver around. (a shortish screwdriver is a big help!) There are two more plastic clips, one on each side of the circuit board, and that should free up the board. I just tipped the shield back, not actually removing it in order to support the circuit board a little bit. Now, locate the pins on the underside of the board that correspond to the aforementioned connector for the colored cables. Reheat the solder joints with a soldering iron, adding or pulling off solder as needed (I sucked off as much as I could and added completely fresh solder). Reconnect everything as it was before and enjoy!

I have 2 of these monitors and have this problem. I was so frustrated turning the monitor off and on until the white line disappeared that one day, I punched the screen. And it worked! So now whenever this happens (about once every other day) I use my palm and smack the lower left corner of the monitor until the white line disappears. I like the color on these screens so I don't want to replace them until I have to. I will NOT buy another Lacie though.

Most likely cause is a bad solder connection at the vertical deflection IC. Most service shops should be able to quickly repair the problem.

Sounds like this one needs component-level troubleshooting in the power supply section.

My brightness control does not work just turned on and can not hardly see anything it is up and running what now


Have you tested it with an external monitor?

I would say you either have a damaged inverter board or screen baclight lamp. Usually the inverter board fails in one of the following ways:

1. When you turn on the laptop, the screen lights up for a short period of time and then goes dark. You still can see an image but it is very dark, almost invisible and definitely not usable. When you restart the laptop, the screen lights up and then goes dark again. The laptop works fine with an external monitor.
2. Your laptop turns on but the screen remains dark all the time. You still can see a very dim image outline. The laptop works fine with an external monitor.
3. The laptop screen works fine for hours or even days, but sometimes it goes very dark as it mentioned above. When you restart the laptop, the screen works fine again.

Inverter failure symptoms are very similar to backlight lamp failure symptoms and in most cases you cannot tell which one is causing the problem until you replace either the inverter board or the backlight lamp. From my personal experience, inverter boards fail more often than backlight lamps. If you have to guess, replace the inverter first.

if you can see the image in the monitor the light tubes are not firing and this is commonly caused by blown capacitors on the power board, the capacitors need to be replaced and the monitor should work fine.

Monitor problem


Hi,

Appreciate the "Ask Me".

I am assuming that you have more than just familiarity with electronic components and circuitry, the use of a DVM and a soldering iron. Further, that you have access to a service manual.

Width problem is basically insufficient horizontal deflection, then analysis would have to be in the horizontal section. Areas to initially focus on:
  1. 12V line and pin 29 of IC401;
  2. 110 V peak to peak at collector of Q403, if yes check Q 402 & 404 as well as T401;
  3. other components that affect the horizontal size are:
  • IC201
  • Q 405, 406, 407 & 408;
  • D409
  • L401
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

White vertical lines in image w/ 2 inch black bar horizontal.


the black bar is from the light tunnel collapsing. the white lines are from the colorwheel or the main board has a cold solder joint. replace the tunnel and colorwheel and have the main board looked at.
