Monitor does not show images when computer is turned on until computer is re started sometimes several times, and/or several keys on keyboard are hit.While screen is black a ticking sound is...


Likely a bad power supply board, and that is almost ALWAYS a bad capacitor on the board. They cost under a dollar to purchase a replacement.

Before you fire the computer up next, try running your hair-dryer (yes, your hair-dryer!) and blowing hot air into the innards of the monitor.

If it starts then with no problem, you have "aced" what it needs for a proper repair: a new capacitor on the power supply board, and you can Google for the parts and the instructions.

LG LCD Monitoer


Check the power supply section first, hopefully it will not be bad lamp assemblies.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

My rca r52wh73 wont turn on the power supply fuse was blown i replaced it and it blew right away. what do i need now and where can i find it? Thanks


You got a bad capcitor then on the power supply. You need to change out the bad capcitor so the fuse will not blow. I would recommend just buying a new power supply to save face as with anything eletronics just reparing one thing as you did brings out new issues.

Remember before touching anything eletrical I advice you if you do not know what your doing leave it to the experts who do thanks for using Fixya.com

Acer X223W monito won;t wake up after sleep.


I have a dual monitor system, both are the x223w. Same problem but only on the second monitor. Backlight shuts off.On/off light stays blue. I have to turn off the monitor and turn it back on. I returned it and Acer could not find any problem so I got it back. No problem for awhile and now a few times over the past couple days. Not good...

No picture on monitor


The Q7 has a tendency to burn up transistors and a high voltage capacitor on the one half of the inverter board which is part of the power board.
I have repaired 1/2 dozen of these with that problem.
Only way to tell for sure would be to open it up and look at it.
If you can do that and send me a picture to bammbamm@ptd.net, I may be able to confirm this.
The other possible problem could be a bad bulb, but since it is fairly new ? that is probably not the issue.
