Here is few question you might want to ask yourself:
Have you try the monitor on another source?
So if it work, what is the resolution the source was set at?
Can you try another video on the source that does not work and compare the resolution?
If the monitor does not work with another source then internal part is failling. inverter for neon lamp most of the time but the power light would lite up. if the power light does not light upe then it is internal power supply. Check the power cable, external power supply, the internal and external power plug (you might want to replace the cable for a test or the power supply if external)
I searched around on the web and found somebody mentioning the power source. I live in south Florida and we do get power surges almost daily. It seemed too good to be true but I decided to try it so I unplugged my monitor from my surge protector and plugged it into another outlet and BAM!!!!!! Crystal clear and like brand new!
It must have been the surge protector.
So if you have a fuzzy monitor one thing you CAN TRY is to change the power source or outlet. It worked for me and saved me a few hundred dollars.
If there is a power outage and the monitor fails to come up, i would want you to take the monitor to a good power supply source and plug it there to see if it will come up, the problem might be with the power source, if not then the problem is with the monitor.if it is dim, i mean the screen then you can be sure is the inverter switch on the monitor,but if i have a monitor problem, the best thing, i would likely do is to get a new one.
Assuming the monitor is powered (if unsure, check the that power cord is connected to a live 120 volt source and the other end is connected to the monitor), check the data (analog VGA or DVI) cable between the monitor and the computer. Make sure the connectors are firmly seated in the respective jacks, and held in place with the retaining screws where provided.
If all four connections (power in and out and the data in and out) are satisfactory, check your monitor's input "source" selection. This may be selectable via dedicated "Source" button on the monitor or from the monitor's "Menu".
When changing the source input types with the button, it will usually take a couple of seconds before an image will display, so allow enough time for the monitor to respond to the change. If changing via menu selection, it may not change until saved or exiting.
If the monitor refuses to display, it may be an issue with your video card. In this case you could try swapping the video card or the monitor to determine which is the culprit.
9 times out of 10, the vertical output IC I501 ( TDA1675 )and resistor R574 (1 ohm, 1 watt) are bad...The resistor opens up because Vert. IC has gone bad. IC doesn't get 30 volts from the power supply, hence , no vertical sweep....
