Ritchard, You may want to try this site: www.slelectronics.net/nec-lcd/monpart.htm will get you to pages with list of other manufacturerers other than just NEC. I'm louie12fix on fixya or lmistyrel @aol. com. Note: Take pictures of how everything go's back together before you take it apart. The board with the Transformers on it and connects to the 4 plugs from the sides of the LCD/FPD is called an INVERTER board. It takes 12v-15v and turns it iinto something like 1200v-1800v and of an AC nature running at a frequency> 30khz. BYE.

GE spacemaker microwave turns off during cooking and display goes black


Step 1:


Door Switch




If the microwave runs for a few seconds and then shuts off, a door switch might have failed intermittently. Check each of the door switches for any signs of overheating, arcing, or burning. Also check each of them for continuity. Replace any of the switches that is visibly damaged or that only has continuity intermittently

Step 2:

Main Control Board




If the microwave runs for a few seconds and stops there may be a short circuit in the main control board. Check other components first, these boards are often misdiagnosed.


Touchpad and Control Panel




If the microwave runs for a few seconds and stops the touchpad and control panel might be defective. There are several other components that can cause this problem, be sure to check any other components before replacing this board.

Touchpad




If the microwave runs for a few seconds and stops the touchpad might be at fault. This is not common. Generally speaking, if the microwave display is working and some of the buttons respond correctly but some don't, the problem is with the touchpad.

High Voltage Transformer




If the microwave runs for a few seconds and stops the high voltage transformer might have an intermittent short. This is not common. Check other components related to the microwave symptom first.

Thermostat




If the microwave runs for a few seconds and stops the thermostat might be defective. Watch our video on testing thermostat

Dell 1900 fp monitor driver


Go to GOOGLE and type DRIVERS for your exact product and model of monitor, which will hopefully give you the correct drivers to download. Softonic would be one place to look. CNET would be another.

Open and look at the tops of the capacitors. I bet there are at least 2-3 "bulging" tops. Replace them and the problem WILL be solved;.

Monitor light blinks no picture


(Please be advise that if you don't have the knowledge, the proper skills and the right tools to open the back cover of your monitor and replace its part...don't risk it...
Otherwise, bring your unit to a credible technician and avail of warranty if there is any.....) If you have guts.. then do the following steps..

You said your monitor will blink but no picture display... well, there are possible reasons why this problem occur..

1. Open the back cover of your monitor..Check the power supply section for possible loose connections and blown capacitors.. Resolder any loose terminal connection on the pcb. Check for any blown capacitor, replace the capacitor with exact value, and also replace any bulging capacitor..If you have successfully replace the parts you can try to turn it on and connect the vga cable in it to the video card of your computer. Turn on also the cpu, if the monitor led turn green and the display came out..that fixed it.

2. In case you have successfully repaired the power supply section and the led of the monitor stays green.. then the problem will be in the inverter board section....Turn off your monitor... open the back cover...on the inverter board section.. check and replaced burnt or overheating high voltage transformer..if one or more of this overheats, it is enough to affect the supply current from the power supply section and that may cause to blow your capacitor...If the ballast transformer is working fine the last thing to check is the backlight inverter (the light that illuminate causing display in your monitor) Replace any busted lamp.. that should fix the black screen on your monitor. ..

If you find this information very useful..please be kind to rate this solution and vote for this on the help below...thanks..




Much appreciated if you rate this help...thanks...

My Dell 1905fp Ultrasharp was coming on intermittently for a little bit and then it would not power up at all.


You said your monitor will be on for little bit and then would not power up anymore... there are two possible reasons why this problem occur..

1. You need to check if the high voltage ballast transformer of your backlight inverter is about to be burned... the transformer is overheating..that's why you experience the monitor working for a couple of minutes and then it will shut off until the transformer cool down again and then it will be ready to work again...

2. You need to check the power supply section for possible loose connections and blown capacitors.. the ballast transformer has direct effect on power supply section.. when there is overheating transformer,,, the supply current from the power supply section becomes unstable.. and will not be able to supply the remaining good working ballast transformer.

In case you do not know, the ballast transformer generates high voltage for the backlight inverter to work..The backlight inverter is the light source that is responsible for the image display of your screen...If the ballast transformer is not working or if the backlight is busted then the only thing that you will see in your screen is black....

Please be advise that if you don't have the knowledge, the proper skills and the right tools to open the back cover of your monitor and replace its part...don't risk it...

Otherwise, bring your unit to a credible technician and avail of warranty if there is any.....

GE microwave


This is usually an indication that the magnetron has gone bad, or something in the high voltage network controls the magnetron. Any one of the following components could be at fault: 1. Magnetron 2. High Voltage Transformer 3. High Voltage Diode 4. Magnetron Thermal Cut-out 5. High Voltage Capacitor 6. Interconnecting wiring I do not advocate taking any voltage measurements inside the High Voltage section of a microwave since the voltages can be as much as 14,000 volts or higher. If you are savvy enough to attempt yourself, WITH THE MICROWAVE UNPLUGGED, you will need to disassemble the unit to get to the high voltage section and take resistance readings. The magnetron or diode are likely suspects. If the magnetron or the transformer are bad, the repair costs can meet or exceed the price of the oven. Let me know if you need further assistance.
