Hi,

The problem is known. You have to replace 2 capacitors on control board. C604 and C507 are 2 10uf capacitors that produce this problem.
My monitor working fine since i had replaced them. I hope i could help you.

Hi this is the way how to examine what's wrong with your LCD monitors. Power on both CPU and monitor. After that, you have to check if you can see the image on the screen or not by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. Like me, I can see window image using flashlight and check lamps inside. Some of them were broken and it is easily replaced. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.

My dell ultra sharp 1702 monitor blinks for quite awhile before starting up when I turn it on...?


Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed Dell monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Dell flat screen started flashing, green light was blinking then screen went blank and green light is on. Tried unplugging etc...time for a new one?


No. It is not a Flat Screen issue. It is a CPU issue. You CPU is not sending signal to your flat screen so the green light is flashing. Try to:

1. Reset OR
2. Unplug the CPU case, Open the CPU, the interchange the RAM modules, OR
3. Same with step 2 but unplug and then plug back in all expansion cards like audio, video cards, etc.

It seems that your system needs discharging from a frozen state.

Regards!

HP 1702 Monitor comes on but immediately goes off.


There are five capacitors on the power board which have dried out and need replacement. A reputable repair shop should be able to fix this for around $50.00 including labor.
