No power to monitor. Completely dead.

After returning to my desk after a break, Monitor was completely dead. No "ON' led indication. Would this be the high voltage powersupply?

LCD (pre the manual you threw away, and my exp.)
1: does it have A.C. power, use a desk lamp to test that jack.
2: does the power lamp come on, ? on monitor.
3: does the OSD work? (press mon, keys? see a box> )
4: does the monitor work on other systems, PC,TV,laptops.etc?
5: try a new cable?

if all 5 fail, or to correct it, the monitor is toast.

Iiyama E2607WS just stopped working - completely dead - internal fuse OK


In most cases there are one or two capacitors in the power supply that open, and in some situations they have a bulge at the top making it easier to spot.

My scepter e240 wont power on is it junk or what


dear,

first of all, check whether the power on/off button light (LED) turns on or not. If it goes on either orange or yellow/green, it means its not completely dead. If its not doing that then its a different matter.
Then you have to check the power cord that can be problematic and need replacement. If it is ok then you have to disassemble your monitor to check the inner fuse that is related with the power supply.

Most probably it is cause by the Capacitor, if it is dead and after checking the fuse!

best of luck!

My problem is that my computer screen just won't turn on! I can hear the fan running so how do I fix it?


Turn off your computer first.
if the power led indicator of your monitor is blinking then your monitor is not dead or damage, you just need to clean the video card of your computer, open your computer then clean the gold plated sockets if you are using a video card. but if you are using the built in video input then clean the memory of the computer. return the parts back to its proper place then try turning your computer On again.

Good Luck, Don't forget to vote for my rating, thanks

New monitor purchased with a package with compaq desk top, but trying to use with a Acer desk top, screen comes on , but then goes completely dark after about two seconds. If switched off then on, again...


Could be a faulty monitor, or could be missing the driver information for the monitor. Usually when you first connect it will use a generic driver to start but then should automatically download and install the correct driver information for the monitor. Could also just be a faulty cable, power or VGA, HDMI, which ever you are using. Try using different cables first, then you can google search for the correct driver and manually install it.

Power dies when video signal applied


I fixed this problem by replacing all the electrolytics 1000uF and 1500uF on the power supply/inverter board. All were either bulging or had burst at the bottom rubber seal. This cleared up all problems and I am using this monitor successfully at this very moment.

Monitor is totally dead


Through my past experience I mwould remove the solder point at the input power B+ line to primary winding FBT. If the HOT has shorted there will be no power.Straight to the point if you know where the HOT is , you can desolder the middle pin or collector of the HOT transistor. If you desolder the pin which result the power led light turn up. That indicates either FBT or HOT has shorted
