Question about Computers & Internet

1 Answer

Losing backlight in about 3 seconds

I've found the problem to be at location Q-755, which is an SMD IC. The chip has been hot enough to melt the solder from the pads. I need to know the cross on the IC or where I can get one. The numbers are as follows:
4431
AE
W25C

This monitor is a Compaq D5064 (1720) LCD.
Would appreciate any help.

Thanks,
electrotech

I have a proview lcd monitor model pl866s .What is the size of the power connector for the 19vdc @3068a psu?I have an extra psu with the correct voltage /current .Thanks Robert.


For the above LCD Monitor, I actually saw a small spark at the top part of the main board once the power input jack was connected. It prompted me to the exact location and when I check the SMD ceramic capacitor (that generated the spark underneath it) with analog meter set to X 10 K ohm range; it actually developed a slight short circuit. Replacing only the fuse and the SMD ceramic capacitor solved the no power problem in this 19" LCD Monitor. This Monitor uses the inverter IC (OZ960G), A1084-25CM (2.5 volts voltage regulator), AMC1117-3.3 (3.3 volts voltage regulator), ADC IC (MST8136B) and CPU IC (MYSON MTV312MV64).

Check your power source, maybe it is not getting enough power or getting to much power. Its happened to my amps before.

Very dark screen


Hi yes it looks like the inverter has failed and will need replacing, or if your compitent enough you can fix it at board level. The usual suspecs are a small SMD fuse on the inverter board / power supply board and/or buldging capacitors which look like blue or black cans.

hope this helps.

Monitor turns off after 4-5 seconds


hi every one, i hope this helps and am proud to say/or not that i am now using my philips php-19x (aka proview 900w/Mag LT916s Model 900p/ Xerox) and yes turn on the monitor 2 seconds screen goes black and the blue power light stay lit, but if you shine a torch onto the screen you can see the lcd display is working, and if you turn the power off and on the cycle starts again, like most of us we checked the web to no avail, untill yesterday. I have been playing with this monitor for 3 months on and off after a kind fellow gave me this monitor for free on uk freecycle and of course i checked all the caps on the psu/inverter pcb and more components all seemed fine checked the ccfl lamps by taking them out of the lcd panel (15 minutes to dismantle) both lamps where fine not orange, a nice bright light, and knowing that if the monitor started woking ok and the back lights did not fail it would run like this for ever until you turned the monitor off / video blanking so i was convinced that there was no fault with the psu/inverter board, and as i stated i found the solution at last (yeh) and here it is many that's to all on the bad caps forum and of course the main man -----barry wilkins-----

Re: Mag LT916s Model 900p 19" LCD dropping like flies

I have got to the bottom of this ,after I got one of scopes out (PM 97) the output of the TL 494 IC was disappearing .The IC seems to crash easily ,I think the oscillator on pins 5&6 actually stops.
I cleaned the whole board with an aerosol of PCB cleaner and heated up the PCB up with a small craft heat gun to quite hot .
I fitted a 0.01 mfd capacitor across the IC pins 12 to 7 to decouple the VSS supply ,because I felt the cause of the IC stopping could be interference based
The monitor now runs for all day with no sign of the backlights cutting out.
I found out this LCD display was made by proview.

Help in identifying this transistor for my VX924


Are they black with 3 SMD pads? They should have a tiny tiny number on the top corresponding to a SMD code that will tell you what they are (example: D9A means 5.5V zener diode).

http://www.tkb-4u.com/code/smdcode/indexsmdcode.php

You should be able to just get a new inverter or repurpose an inverter out of something else to get it working again. An inverter that powers any other CCFL bulb should work fine.

Monitor problem


You are experiencing an inverter board failure. You will need to replace or repair the inverter. The inverter drives the CCFL lamps that illuminate the screen if the lamps draw to much current or components on the board are overheating it will shut down the backlights. Some monitors have cold solder joints on the toroidal coils of the inverter that causes this problem, very typical with HP monitors, If you are handy with a solder iron you may try just re-soldering board and replacing push-pull transistors for a few more years of use. Provide make and model and I can be more specific about probable cause and solution.

I DID REPAIR A MONITOR WITH THE SAME PROBLEM. IT TURNED OUT, THAT ONE OF THE TWO HIGH TENSION GENERATORS FOR THE 2 LIGHTTUBES WAS BURNED OUT. BY REPLACING THE POWER TRANSISTORS AND THE 3 AMP. FUSE ON THE MAINBOARD THE MONITOR IS RUNNING AGAIN VERY WELL.

Screen goes black in half a second....


Call the service dept. in the above post. Tell them the model and serial number of your monitor and order a backlight inverter board(approx. $35 plus shipping). Open up the monitor and plug it in, should fix the problem. This problem could also be caused by one or more backlights(small flourescent tubes) being bad. I just fixed a Neovo F-417 display by replacing one of the backlight assemblys. I also just fixed a Neovo E-17DA monitor by replacing the inverter board.
