I have a emachines e19t5wtft lcd monitor that when I plug it in and turn it on it comes on mominteraly then goes off and will not do the same untill I unplug it for a while

Hi,

This is most likely a backlight related problem. It is most likely one of two problems:

1) Something is wrong with your power/inverter board. Most likely you will need to replace bulging or bad capacitors on the power board. They will like have voltages between 16-25V and capacitances of 470-1000uF. You will need to disassemble the monitor, remove its power board, and inspect it. If you notice bad capacitors, you will need to desolder them from the board and solder on new compatible ones. This should solve the problem.

OR

2) If replacing the capacitors doesn't solve the problem, the problem may be with your backlights themselves. If you are able to test them, that would be best. Replacing them is a pain as you will have to disassemble the LCD panel itself to get them out. You will then have to replace them with compatible backlights of the same size, which you can salvage from similarly sized broken monitors.

Keep in mind that the suggested actions above are for individuals with some experiences in soldering and repairing circuit boards or LCDs. Also be sure to wear anti-static gloves or wristband and keep the monitor unplugged when performing the above stated actions (except of course when testing voltages).

Please check this link for the user guide of emachines monitors and check the troubleshoot section..hope it will help….
