17" flatron crt monitor only green led blinking and tick tick sound .No display


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

Computor keeps trying to restart,monitor only shows vertical lines,first black and white then colored lines,


Probably the problem is not with the monitor. Your computer is defective and probably the lines appear because your VGA is defective.
To make sure your monitor is OK, you can connect it to another computer.
First check replacing the RAMs and then VGA.

Color Problem


all of you mentioned are correct. if they cannot work on color setting of your monitor and for the setting of your resolutions it could be the monitor. the monitor cannot support the color bit mode which required for the windows vista it could be a 16bit color mode which only display for not more than 63herts for the Hi color vsynch compare for the 256color if you have a Hi color settings for about more than 63herst vsynch. it cannot display properly. thanks

I replaced the 3 capacitors now there's just bright white screen


Open your monitor back up and look for unplugged connectors, especially the one to the back of the LCD. I had this same problem with a HP F1703. The owner whacked it so hard when the backlight stopped that they dislodged the connector.

Dark picture


you probably have a bad capacitor on the invertor board. try shining a flashlight into it to see if you can see anything. if capacitors are good, you might have some burnt out backlight bulbs. i just had the same problem, replaced the capacitors but messed something else up on the way i guess cause now all i have is a bright white screen with a few colors here and there.

Normally TFT monitor backlights have a life of around 40,000hrs .Open up the monitor and check visually for bulged leaky capacitors.This monitor is reputed to fail due to dry solders on Inverter pcb.
