Answers :

I would Suggest you don't try fixing this yourself. CRT monitors are basically the same as TV's, and TV's have enough high voltage stored in them to zap and kill, if you just touch the wrong spot. It's not enough to unplug them because they will still store the voltage in the caps. So please wait untill you really have enough training to do something like this. Unless you're 100 % aware of all the risks please don't ever touch a CRT.\015\012\015\012Anything I tell you is for your general information, and if you still want more detailed information on how to actually do this, what does it all mean, along with all the information on the required equipment and SAFETY PRECAUTIONS, go here: http://www.repairfaq.org/\015\012Or go to a local repair lab and have them explain to you just how dangerous it is. People who do this for a job know not to take chances or sooner or later they will be seriously hurt.\015\012\015\012Is your screen flat green, or do you have a greenish picture?\015\012\015\012If it all green, possibly shorted CRT driver transistor, possibly CRT HK short. Swap the green drive transistor with one of the others...if the problem stays with the green, install a heater isolation transformer, if it moves to the different color, replace the transistor. If the screen stayed green when you swapped transistors, there is almost certainly a heater-cathode short on the green cathode. Installing a heater isolation transformer may be a difficult project. The success rate though is not too bad, and a repair shop may be able to do it reasonable cheaply. Here's what you do: (read first...if you don't understand any part of it, DONT try it, because too much can go wrong)...\015\012\015\012Measure the P-P voltage of the heater pulses.\015\012Turn the set off. Cut the traces to the heaters on the CRT board,\015\012leaving enough to solder to. Cut about a 3' piece of wire.\015\012Wrap 4 turns around the flyback core, and solder the ends to the\015\012heater pins on the CRT.\015\012Turn the set on, and check P-P voltage again. If it's more than 20%\015\012higher than it was, I put a small resistor (1, 2, 3.3 ohms, etc, 1 or 2 watts) in the line to get the voltage back to normal; if it's lower, add another wrap on the flyback core, and check again. If the picture needs brightening beyond what the controls can provide, I'll let the heater voltage go up to 40 or 50% higher than the original, but in these cases the CRT is on the way out, and won't last long.\015\012When things are the way they should be, trim wires to a decent length, allowing a bit extra for sliding the board out later, and insulate all exposed wires and resistor leads. \015\012\015\012If it's a greenish picture, Then it's the picture tube, RGB output transistors, heater to cathode short, or loose connections on the crt board. \015\012\015\012Good luck, and take care
SILLYGIRL!!!! Great call man, could not have said it better myself. I got an article im trying to find on how to make your own isolation transformer as i used to use this all the time. As soon as I find it I will post it here and forward it to ya.

I have a 3 yr Dell UltraSharp 1905FP LCD monitor.

LCD screen shows green shadows typically behind the cursor and eg on each alternate line when in windiws explorer page. It looks a bit like the old printer paper that had alternate white and green lines. The green shadows are in the form of thin bars. Also the red pixels sometimes become brighter especially when displaying photos or playing DVDs. The problem is intermittant - sometimes goes away. Will reappear and get worse causing the screen to flicker a greener then redder hue. When runni
