Monitor show " Protect " can't do anything.

How long is a piece of string?

A list of parts is not going to indicate whether you have connected or installed it correctly. Have you put or attempted to put software on the drive? Is the HDD partitioned and formatted? No drivers installed for video or sound... unless you have an operating system installed.

Too many variables to answer this question, without details of what was done or wasn't done Hardware will operate to some degree even without op system ( monitor and satac DVD drive)

Thanks for using FIXYA

Yes, take it to a repair shop.

You have a failure either in the power supply or one of the power amps. There is likely to be burned component(s) that are not user serviceable.

These things are a bear to work on... Mine failed again and I dread having to work on it.

The protect monitors power supply current drain of the switcher and the power amp balance.

DO NOT USE IT till it is repaired. Continued use or fuse replacement will likely do additional damage.

You need to check out caps in the power supply section first, then check the backlight inverter circuits for bad fuse, transistors. It can also be bad lamps. See example of failed monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

morinj_04, "Switch-mode-power-supply" going into partial shutdown mode. Read more of my BLACK screen and BLACK and BLANK screen responses in my profile. You will get the hint as to what to do!!!

Start by completely turning off the power to it and anything connected to it. Turn all levels down to there lowest volume settings. Check to be sure your speakers are not shorted. Be sure the power voltage is correct. Turn on each of the items, the amp being last. That probably will resolve the problem but I am not that familiar with the unit just trying to help. Most units have stay in protect mode until I cycle the power. Typically they monitor the speaker current hence a short would cause almost an instant protect fault.
Good Luck,

The monitor is probably on protection.

To start unplug monitor from power and from computer and test computer with different monitor to find out if it is monitor or computer fault.

If it is computer fault and no video signal , then test:

• Video cable.
• Video adapter on PC (sometimes integrated on motherboard)
• Motherboard.

If it is monitor fault , then the monitor is on protection.

When on protection you keep having a flashing led on front of the monitor , and monitor turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or a broken contact, identified an internal fault and kicked in , starting the flashing light.


If you are in situation one, then the monitor will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, faulty inverter board, faulty input board, or a fault on LCD Digital Controller board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

Try moving the video cable, and if the cable is not built in, then also try a replacement cable.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

my kvt512 shows PROTECT on the moniter, how do fix it?

You will need a new monitor screen. I have had two screens go on me recently and what you describes normally happens

two case trouble reason and need to do:
1) back light driver (inverter) works not stable and DC power protect. it near some component damage, should repair inverter by egineer.
2) back light (lamp) over life cycle so protect by the inverter, should change new lamp (regular parts)
3) DC power supply not stable or component over life( wave filter capacitor), should be replaced

First you sec your monitor power cable is not loos or power in properly if ok then you sec your monitor VGA cable is properly conect to your pc if ok then you disconnect your VGA cable in your pc then you power on your monitor and sec that youre monetor screen. show a masege or not masage like tiis : CHEEK SIGNAL CABLE or NO SIGNAL : if show this signal then you men your display card is not responding or monitor shows nothing then you meen your monitor is faulty then contact any monitor techenican and solve your monitor problem.
