My Philips brilliance200b monitor has
horisontal thin bug-lines - mostly at the middel and little above the middle of the sreen.
Every 5-20 sec, it starts a degausing and resizeing of he visual screen.
Both sympthoms appears in boot and after burn in (cold and hot electronics)
I guees that, its some capasitors, that needs replacement, but I am not skilled, in detechting such bugs.
Ought I just trash this monitor, or is it just a minor bug, that some electronic-guru will replace at low cost?
Or it it possible that I could find and replace this component - that is: Is this problem a wellknown problem for monitors or Brilliance 201B in general?
Thank you wery much.
Re: Succesive degausinge and horisontal line-bugging
If you do not have high voltage training, messing in a CRT based monitor can hurt you due to the high voltage risk.
Detecting failed electrolytic caps is not hard. I've replaced the caps in my monitor a couple times (It's a 12 year old 21" CRT, that replaced a 10 year old 20" CRT 10 years ago), but you do need basic soldering skills.
An electronics tech could probably fix this for the cost of a hand full of caps, but remember, you will need to pay for service time (skills are costly), and that will probably run 75 to 100 dollars.
If you are concerned that someone may benefit from you lack of ability, then you can have the monitor diagnosed for $35.00 or so in most places, donate it to a charity that refurbishes computers for the needy, and let them fix it :), or just ride that bad boy until it dies (what I'm doing, I'm not replacing the caps a third time, I'm planing on getting a 24" widescreen LCD to replace my 21" CRT)

IF you do not think it is the monitor, replace (if possible) the cable from the computer to the monitor. Sometimes the cable can be loose. Then, check the connection at the video card. The video card may be loose or may need to be replaced. Also, before you decide none of the above is what you want to do, verify that the refresh rate in the computer display control panel is set to the speed the monitor can accept. (right click on the desktop and pick properties then screen resolution/video/monitor options). Screen refresh should be 60hz +/- as a basis and adjust from there.
I really suspect the cable.
Usually the case with this issue is the LCD panel itself. After a certain long period of time, some LCD panels just bug out and stop working. ( not sure why, possibly the way they were assembled and manufactured. For instance the LCD Panel has 8 connectors ((top)) and 3 connectors ((left)) (((Depends on model)))that attach to the main board of the LCD Panel, and on many occasions the thin lines wear and cut and therefore loosing part of your screen. If i explain further how it works i can write you a good explanation, just message me. That is the issue or the Cable connector from the Video Card to the LCD Panel is faulty. Try replacing that or the line will stay there for a long while then eventually your LCD display will begin to show more lines and eventualy Nebula itself. ( unusable )
You can also try repairing the LCD, in some rare cases the only problem when the line shows up is because of the video genesis card inside the FPD. try swapping that out with a known good one and perhaps that will work otherwise eventually the monitor will begin to stop working over time.
