Question about Computers & Internet

1 Answer

Hello, i have a Aoc 2434pw monitor that just lost all its power, it was on overnight as usuall (online business so my pc never shuts down), but i woke up to find that all power to the monitor was not working. I unplugged the monitor from the pc and plugged in a different monitor which worked so it is not the video card. after that i unplugged the power cable for the monitor and after 15mins, plugged it back in and it does not show any power at all.... no lights nothing, it is completely dead ...... i will replace internal parts if needed, so please any info on this problem would be great. thanks . Ronald

Many flat screen monitors were manufactured with faulty capacitors.
See if you can open the monitor and examine the power supply for any "domed" capacitors. The top of the capacitor should be flat, but if pressure has built up inside, they become domed, indicating that they have failed.
Replace any of them that you see to be damaged and there is a good chance that the monitor will work again.
It has been a problem with quite a number of monitors. The electrolyte inside the capacitors was cheaper and just doesn't hold up.
Good luck

This sounds like a computer problem and not really a television problem. Check your driver files.

Try removing your driver files. Then disconnect your AOC monitor. Reboot the computer and login. Shut down the computer and reconnect the AOC monitor. Start the computer. Now install the monitor drivers.

My aoc monitor 2216sw shut down after three seconds on


It sounds defective. When the high voltage power units stop working; you will experience this type of problem. I would call AOC and see if the monitor is under warranty. Otherwise, seek an alternative monitor to use.

Existing Graphics Card Radeon X300, which one to


I have looked it up on the internet, the graphics card is capable of displaying your monitors resolution. I am therefore assuming you want a new graphics card for 3d applications, since 2d is easily rendered by this card.
However, simply replacing the graphics card will not help. You will probably have a hard time finding a card that can fit on your mainboard, and even if you do, your prcessor will not be fast enough to send the required data to the graphics card.
In this case you will have to buy a new PC, I'm sorry. If I did not understand what you meant, please post a comment.

Regards,
Yannick.

Same problem--AOC monitor "goes to sleep" after an hour online


Hello,

It sounds like you have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of the monitor. If you are good at electronics repair/soldering you can usually fix the problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way. If you can't do the repair we offer a repair service, contact us for more details.

I hope this helps, if so please rate my solution.

No display


Try Unplugging the monitor and plugging back in again,,,you dont have to shut the PC down to do this,,,if it starts backup,,,then good... if it doesnt,,then you need another Monitor.
An LCD monitor is better for your eyes anyway.
