    I have exactly the same problem. When i turn the monitor on, the power LED going on and off and nothing happends on display. The power supply board is OK. The problem appears only wenn the control board is attached to power supply board dose'nt matter the LCD is connected to the control board or not.

    I've already replaced all capacitors on the control board without success. Have anybody any idea? Please help...

I have a Dell 193fp monitor. It's 5 years old and is used infrequently. Today the Power button started to flash amber repepatedly while making a slight clicking noise. After turning it on and off,...


This sounds like the power capacitors are failing, which is not uncommon for a monitor of this age. You can take it to a TV repairman and get the offending capacitors replaced, however, the cost of replacement may outweigh the cost of a second hand monitor

The screen seems to be slowly turning white.


More than likely a manufacture defect. If it is not that old; I suggest contacting the manufacturer to get it replaced. Most LCD"s have 1 year warranty, and it's certainly, not weird to see 3 years.

Hi my monitor has bright colours on it and i cant make out what im doin its really bright and hurts my eyes


Turn off the pc but leave the monitor on. unhook the monitor from the pc. the screen SHOULD run a "self test" with a moving white green red blue box. if that box is on a bare black screen and there are no bright spots or cracks or anything weird looking, then the screen itself is ok. If however, you see odd shades of blue and pink and it looks cracked or scratched or has lines in it, then it is time to replace that screen.

Probably blown capacitors, the 19" widescreen uses 6 16V 1000uF
Do you have a soldering gun? Its not that hard to fix, get the capacitors on ebay for $6-$8 with shipping.

Monitor won't turn on.


Does the cord plug directly from the wall into the monitor, or is there a power "brick" adapter between?

If there's a "brick" listen to see if the hissing is coming from the monitor itself or the brick. If the hissing is coming from the brick you may just need a new power adapter.

If there's no brick or the hissing is coming from the monitor, the monitor probably needs repair. With the price of LCD monitors these days compared to the price of labor, you're probably better off getting a new LCD monitor. Just make sure you take your old one to a proper E-Waste facility so it doesn't pollute the environment.

Problem when turning monitor off


mcdevito75 here LCD, or liquid Crystal display, chances are the crackling is the inside liquid display trying to capture the in comming electricity to make a display picture. Remember even an LCD is nothing more than a light bulb, a very intricate light bulb but a light bulb, and you have light bulbs burn out when you put them on and almost never as the are on burning. Turning the monitor itself off won"t really save electricity or the monitor itself as, when you shut down the computer from Start (left side of screen) the monitors screen saver comes on for 10--20 minutes then goes off, at this point the electricity is at the monitors on/off switch and not going thru the monitor at all. If you turn the monitor off at it"s on/off switch, the sudden jump of electricity to the monitor from it"s on/off switch could hurt it, or even the switch. I have a friend who turns off the monitor also and that friend had a bad monitor in 3 years. I never turn my monitor off just the computer itself. I'd speak with a Radio Shack, Staples, Best Buy ETC. for more advise. Me I;d say leave the monitor on. Hope this helps.
