Dead Monitor My issue is with a dead monitor. I need to know if anyone knows where I can find the inner componets for my LT776s {ie: inverter board, power supply interface etc.}

my 12 power supply was only 500ma, not the 4a needed. Got the monitor to power up but now the screen goes dark after 2 sec. Looks like a bad backlight issue. I'll replace the inverter board.

thanks

Hi...there,
A simple way to check your AC Adapter, plugged into a socket and see if it lite green... If you don't see a green light lite on the AC Adapter, then it's DEAD... You can order the AC Adapter @ www.3rd-rocks.com but sometime you need to replaced both. Have a nice day!

Hi,

Your description is the external power supply/adapter for a Mag Innovision LT776s 17 in. Flat Panel LCD Monitor. One may be purchased here. Aftermarket/replacements may be found here, here or here. Pls verify that the plug matches the jack and the polarity is correct. Additionally, if it would be a replacement, pls check the voltage and current rating.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

The inverters often fail from capacitors that have lost so much of their original capacitance and developed losses great enough to disable the circuit.

If you can identify the inverter section, you might want to replace any capacitors you see - a 'shotgun' approach, since locating the defective cap requires a fairly wide range capacitance meter with loss (DF) measurement feature unless you are lucky enough to locate one with a bulging top or crystalline deposits around the base. These instruments cost upwards of $200 so for a single use it doesn't make sense.  About the only part in that circuit that might be unique is the transformer so everything else can be bought or substituted. The lamp itself could have failed and these are available under similar part numbers from multiple sources. If the lamp has strong discoloration toward the ends, I would replace this first.

I do not what type of inverter you have is it true wave? some inverters are cheep as they are not a true waves and they do effect the life of the Tv/Computers, etc. Tv still covered take it back and do not tell them that you connected it to inverter

my monitor samston 17`` have a problem with screen ten minute after on it`s become on / off screen ( it`s black, it`s white ) when it`s happen the wording can read, when it`s on.

Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!

Actually this is a 'warning' signal from your lcd monitor. The problem is your lcd ccfl lamp are near to their life, need to change. The ccfl lamp like our home fluorescent lamp, when the lamp need to dead, the lamp will flickering first, after some time, will totally off(dead). So, this is a signal for you. Some lcd monitor, when their inverter board are using fairchild inverter ic(oz series), will easily shutdown your monitor when they detected some flickering on your screen (ccfl lamp).

if you can get into the menu your monitor should be ok. check the cables to the computer.you might have a lose connector on the videocard.wiggle the cable and watch the monitor. if nothing happens you might have a bad videocard. best way to chack monitor: connect it to a known good computer......

If you have the pc on and the monitor light stays green, take a flashlight to the screen. If you can see the images while shining the flashlight into the screen, they will be hard to see but they will be viewable, then its most likely the back light. The vx900 takes 4 bulbs and they are about $12 US each. Anyone who knows how to solder should be able to replace them.
