SOURCE: My Neovo f-417 LCD Monitor is switching off after

This means there is a hardware failure in the monitor that could be either blown CAPs or a shorted out inverter. It is difficult and dangerous to replace both of those(involving soldering and desoldering) if you don't know how as LCD's are made of a hazardous material. I would try new cables and on a different computer as a last resort and if that doesnt work then your monitor is trashed. If it works on another computer then the issue is not with your monitor. Good luck!

SOURCE: Samsung 932B Plus monitor does not turn on. Blinking LED

If you can open up the monitor from the back and get the cover off. Look on the power board and see if there are any puffy capacitors, most of the caps will have a silver flat top but if there are any bad ones, they will have a puffy top that stick up.

If you see any then make sure you replace them with capacitors of the same Uf rating and at least the same volts or more.

If you don't see any puffy caps then that means the screen is bad and the whole monitor would need to be replaced.

Testimonial: "Opened the LCD monitor up, and it was as he said. A bad capacitor. Thanks!! Replied within minutes."

SOURCE: The monitor won't go on after holding the power button

disconnect all the cables except the power cable and then turn the monitor on you would see a test screen if it still happens your monitor is faulty and better buy a new one as repairing is usually expensive .

SOURCE: neovo x17a starts up then screen goes blank. unit

The problem can be the inverter transformers or lamps assembly.
You can look for number as printed on the transformers and go to www.lcdparts.net to look for pinout and resistance reading. Checking for bad lamps will be more difficult unless you have spare test lamps.
One thing you will have to remember is that the cap can look OK but it can have high ESR, you will need cap tester that can do the test.

That is a security configuration on HP Laptops, depending on the way they blink is the problem your machine has.

Here is the web page where this info is posted, in case you need more info, hope this helps you to determain.

This document pertains to HP Notebook PCs with the HP Unified Extensible Firmware Interface (UEFI) beginning in late-2008. On startup, you may see a blank screen. If the diagnostic utilities detect a specific problem with hardware components, the fan turns on, but the screen remains blank. To help identify the cause of the problem, various LED lights on the keyboard blink a series of codes. The diagnostic utilities use the LEDs near the Num Lock or Caps Lock keys to blink a series of error codes. At the end of the series the blinking stops. The pattern of blinks will occur any time you attempt to start the computer until the error is resolved. Battery power LED blinks The Battery power LED indicates the condition of the power supply. When starting the computer, or when the computer is in operation, use the chart to identify the power condition. Battery Power LED Component Tested Error Condition Battery power LED off, and Caps Lock/Num Lock off Battery or AC Adapter AC adapter not connected or failure

Battery low charge or failure Battery power LED blinking Battery Insufficient charge on the battery When new computer is used for first time, the white LED light for the AC power connector blinks. Battery is still in "Shipping Mode", the light continues to blink even when AC power is connected.

To resolve, turn off notebook, connect AC power and allow battery to charge for at least 30 minutes, then start computer. LEDs near Caps Lock and Number Lock keys blink when starting notebook The LED lights near the Caps Lock and Num Lock keys will blink if an error is detected during the start up process. The LEDs will blink a number of times in a sequence and then stop. The number of blinks in the sequence indicates what component caused an error when it was being tested during start up. If the LEDs stop blinking and the computer does not start, you can press the power button again to repeat the tests. Count the number of blinks, and use the chart to identify the error condition. Knowing the number of blinks is helpful when you contact an HP support agent for technical help.

I have a sharp aquos lc-c4677un its not turning on at all now. When I push the power botton on the tv, the power light turns on and about 2-3sec the power and opc light start to blink and thats about it.


How are the power and opc lights blinking? Do they blink simultaneously or does one blink then the other? How many time do they blink per second? Also have you had it fixed yet? and if so what was done? I had a similar problem with my set.

On My Dv5-1125nr both the caps lock and num lock keeps blinking when i turn it on. It's wont boot at all. What kind of hardware problem is this?


First remove the battery and power cord for about a minute. Then plug back in and see if that helps. Otherwise please read the following:

Green power light blinks for 1 minute then the lamp light blinks


When Lamp of the TV has been blown out, the LAMP light blinks in red.
When there is an internal malfunction in the TV, the Power led blinks and there will not be any picture on the screen.
Since, both are happening with your TV, it seems that there is an internal malfunction. Hence, your TV requires service.

You may try the following troubleshooting steps before getting the TV serviced.

Disconnect the Power cord from the Wall outlet and connect it to a different working wall outlet.
Disconnect surge protectors if you are using.
Then try resetting the TV to the Factory default settings to check whether the issue is resolved.

LED blinks in milli seconds and the images appear too late.


If your lcd comes with ac adapter open this and check for blown or bulge capacitors, replace this with same value.

If your monitor comes with plug cable, open your monitor (too risky to do it by yourself) check the power supply section, check and replace blown and bulge caps.

3 flashing lights


the 3 blinking LEDs mean the lamp may be defective. Be sure the lamp is making contact with the sockets within the lamp compartment, also make sure the lamp is the correct one for your model. The set can be reset by unpluggimg the power cord for 5 minutes then plug it back in, if the 3 LEDs still blink check the lamp if its making contact and its the correct lamp for your model, suspect the ballast
