It sounds like you have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of the monitor. If you are good at electronics repair/soldering you can usually fix the problem. Check out a few pictures on my web site You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping.

I hope this helps, if so please rate my solution.

    Hello again,

    Can you take a few pictures of boards in your monitor and I will see if we can get it going for you.


  • Buddy Mcsparrin Jul 23, 2009

    Yes, Got the photos and I am working on the problem. I do need to check, there are 2 versions of your monitor, one has an external power supply and one has it built in. Which version do you have?

  • Buddy Mcsparrin Jul 23, 2009

    Does the monitor have a power adapter or does a big power cord plug right into the monitor? If you have the model with the power adapter it should have a green power light.

  • Buddy Mcsparrin Jul 23, 2009

    Can you check the adapter, my specs show a standard round plug with only center and outside connections not 4 pin. Also does the light on the power adapter blink or pulse at all?

  • Buddy Mcsparrin Jul 24, 2009

    Yes, We are looking into the problem.


  • Buddy Mcsparrin Jul 29, 2009

    NO, Still doing research on the model.

Fuel safety switch location or other reasons it won't start after crash.

Generally speaking, only Ford products have a safety switch or inertia switch for the fuel system. This includes some Mazda models.
I would start with the basics and check for power to the coil and the fuel pump relay.

I have two of these dehumidifiers. They won't go on automatically. I don't understand the settings. One of them won't stay on at all. It runs and then shuts off.

As per your problem, that the dehumidifier shuts offautomatically - If yourdehumidifier froze, the compressor will shut off automatically. Allow the iceto melt before emptying the tank and restart the dehumidifier. Hope this will help you. Good Luck.

I have a KDS 5ms model 900W this was never used as my sister gave it to me since she was unable to get it to work. but like the others it won't stay on for more then 7 secs and you need to push the power...

These have problems with burning up transistors on the inverter side of the powerboard.
Sometimes they are fixable, sometimes not. It depends on which board is in it (they used 2 different styles)
I have done a few of these.
If you can open it up and send me a picture of the board to, I may be able to tell you more.

RAD 9p shutting off Have checked all capacitors


The capacitors need to checked with an ESR meter. Althought capacitors sometimes bulge when they go bad this is not always true. Capacitors change value internally very easily when the conditions are right. High heat.

You can send this to my company for repair or if you need more help go ahead and email me.
