Yes its CRT. I think you must be right as I have tried everything else. How can I clean this without dying. Thanks It may also be a leaky capacitor, but we will start with the dust

If you don't feel confident taking the monitor apart (see below if you do :)) then you can try the following: Get a can of "Pressurised Air". Turn off the monitor, unplug it and leave it for 10-15 minutes for the capacitors to discharge fully [so you don't go pop :)] . Give the can a few short sharp blasts through all of the vent holes in the monitor - the reason you only want short blasts is that it can be very cold if you spray for a prolonged period (due to expansion of gases causing a temperature drop) and may crack the tube. Leave 10 minutes for it all the stabilise, dust to settle, etc. Try the monitor. If you do feel confident about removing the case of your monitor (I have done this faaaar too many times :) then move the monitor to a solid work area, preferably wooden. Leave it for 10-15 mins for the capacitors to discharge fully. Lay a cloth/towel on the surface and lay the monitor CAREFULLY on its front (glass) end. Remove all the screws and carefully remove the back casing. You may have to feed the cabling through the holes in the case. Using a can of pressurised air and a soft paintbrush (for those stubborn areas). BE CAREFUL NOT TO REMOVE ANY CONNECTORS, NOR TO KNOCK THE CIRCUIT BOARD OFF THE BACK OF THE TUBE. Be careful not to move any of the components on the boards too - most of them will stand up to light brushing. When you have finished your internal renovation work, carefully slide the case back on (remembering to feed the cables [if required] as you go). Put your screws back in. Leave 10 mins for the dust to settle. Plug and pray :) If the problem persists after the second option then either you didn't do a very good job, or a component part is on its way out. I have had one go bang after it had been fizzing for a while, but I have yet to break a monitor by taking it apart :g:. Just make sure it has been off for a little while (and by that I mean that it has no power lead connected!) to make sure that all the electricity is discharged from it. Hope this helps :) Jon

I don't think I'll tough it. I did have a tv repair lab course in the Air Force and we used discharge rodes. bloody hell maybe its time for a tft thing. On Monday 17 May 2004 15:45, Joao - Calcados Jacob S/A wrote:

On Monday 17 May 2004 20:45, Joao - Calcados Jacob S/A wrote: the proper name for it, I mean the one that is supposed to slowly discharge caps etc) can be "inadequate". Oh, and make sure you take off ANY metal jewellry too, as it can touch things, even if you don't ;) I have seen the burn marks and melted bracelet of a friend who forgot whilst the monitor was on *shakes head* silly boy. You could always wear washing-up-gloves [dry, naturally :)] and make sure the glove opening is tucked under your sleeves.... Just be careful!

<BIG RED LETTERS> If being of sound mind, you go this way, don't just remove the power lead, remove all leads. The CRT is a 20kV capacitor in its own right. You don't want it to find one end connected to ground via an audio lead or similar, because that will make the other end of the capacitor [the HT lead, where you are likely to find all the dust] 20kV relative to your fingers. If this advice is not obvious to you, or you don't understand it any way, then take the job to a TV repair man. The symptoms, [hissing and resizing of image] are bread and butter to them. <END BIG RED LETTERS> Vince

If you have no electronic experience, it would be wise to let someone who does do it for you. The 25 KV won't kill you, altho the shock it gives you could send your arm flying into the wall and break your elbow, or something like that. (I had a friend in the TV repair business that this happened to! And he supposedly knew what he was doing.) Also, you probably need a special screwdriver to open the case, which you very likely don't have. --doug

Is it possible that you're running your monitor at a speed/resolution combination that it's not designed for? If you are, you could damage it severely, so check it out right away.
