If you have another monitor, plug that one into the system and see if it works, if it does its the monitor that is bad if it does not it is the video card.

How To Repair LCD Monitor


The most common problems on Samsung LCD monitor/TV:
  • The power can not turn on, the red light flashing
  • the monitor on for a while and then turn off, then the red light flashing.
This is due to the weakening of the capacitor in the power supply module.
let's go hunting for bad capacitor.


I will explain how to:

  • Open the case of the LCD
basically in all LCD monitors have two circuit boards (power supply board and system board)
  • After you open you will see the two boards are
  • You see a board that has a socket for the power source. wrote that the board we're looking for (power supply board)
  • Remove all cables connected to the board and take out the board. (get noted before you unplug it)
  • Now you see it components on board, we looking for capacitor.(see picture below)

  • Looking for damaged capacitors, physically you will see a capacitor on the top like a bloated (see picture below)

  • Replace the damaged capacitor with the same value that you can see on the surface of the capacitor. (In this step you need any soldering tool)
My advice: replace capacitors with higher voltage, like 10V replace with 16V or 25V will be fine.

Have a Nice Repair :)

Compac d-530 won't start red light under power button flashing


Take out the battery and only hook up the AC Adapter. Try turning on your laptop and if you still only get a flashing power button then try another AC Adapter. If the same thing happens then that means the motherboard is bad and would need to be replaced.

Hello have a problem with tv Model is: lg


http://lgknowledgebase.com/kb/index.php?View=entry&EntryID=6281

The above link goes to lg's website describing the red flashing light where the power switch is, and

another switch down below which can turn that light off.

Try switching that other switch below off so the light turns off. Then, switch it back on.

If that doesn't work, then service should be scheduled for this discontinued model.

Hope this helps on your lg tv.

Booting up


one light is for hardrive activity , the other is to show the power is on.. the flashing one is most likely the power light as most computers will tell you when thier ill....the beeping is an error code and should be in some pattern EG: Power LED blinks red twice, once a second, followed by a two second pause. Or something like that. Take note of the pattern and repost it here, then we can give you a specific area to look at.

MY mouse has a red light that continously flashes. I charge it at night and all day the red lit flashes. Time for a new mouse or what?????


You need to tell us more then "MY mouse"... but I'll try to help.
First: there must be button to power off/on your mouse, switch to off and then on. If red light continues to flash clean connections on mouse and on dock (where you charge mouse), try to charge it, if red light continues to flash check if you can replace battery if not it's time for new mouse.

Red light flashing on power button


Sounds like the hard drive has had a failure, you need to get a replacement one, and reinstall it, along with the opperating system, and any other programs that were on the old one.
