Hi its about a monitor

Hi ser41sosa, my name is Joon, and I was going through this site looking for solutions how to fix my monitor and saw your post on "Flat Screen Trouble". I have a dell E172FPb lcd monitor, had it for several years now and suddenly the monitor doesnt display anything and gives out a weird pulsing sound every second. I dont know much about monitors and sincerely asking for your help/advice. If you know the solution to it please reply back to me on my email if possible. Thank you for your time and have a great day.

There are 4 transistoe c5707 these are used to switch off an on the back light circuit when these go bad thes cause power to do a on off pulse like you described these may be bad but i would bet that the solder hold them on the board is crack a very common issue i have fixed 100s of these monitors with out needing any parts at all they are know for bad solder joints cause they heat up and cool down so fast the the solder cracks. those transistors cost like 1.49 each if they are bad.

See if you can change the video cable and get the same problem. Make sure it is plugged in securely (both video and power cords).

If same thing happens with a different cable try a different monitor. Maybe if you don't already have another one, someone you know can let you use theirs for a day.

If neither option works, it's probably your video card. If changing the monitor works then it's probably your monitor either going bad or try reinstalling the video driver on your computer.

Let me know if anything works, I hope this helps

Lg Flatron L226wTQ, power button failing


Hello,

This problem is usually caused by a failure in the power supply board which in turn is caused by a failure of the filter capacitors. We have a repair guide article posted on our web site at: http://www.ccl-la.com/blog/index.php/lg-l226wtq-bf-monitor-repair/ Check out the article and then open your monitor up and look for the failed capacitors, replace them if found and you should be back going again.

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

Syncmaster 930bf black screen


Hello,

its a common problem for LCD monitors after 2-3 years of use. The power supply that powers the back lights has gone out. If you can solder you should be able to do the repair yourself. The problem is caused by parts called capacitors that get over heated in the monitor case and blow out. You can go to our site at: www.ccl-la.com/badcaps.htm to see what the parts look like when they blow out. Open the back of your monitor and replace all of the ones that look like the pictures. We have repair guide on the site for your model with pictures of what to do. We also have a repair kit available. If you don't want to do the repair yourself we offer a repair service for $30.00 plus return shipping. Let me know if you have any additional questions.

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

Screen turns on for a second then flashes off. Just saw a post that said this could be a capacitor problem. The Monitor is the 225bw not the 275t


Hello,

It sounds like you have a monitor with a common problem. After a few years some LCD monitorswillblow a power supply. The problem is caused by parts called capacitorsoverheating 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.You should find 5 bad capacitors. If you can take a picture or two of your board and email them to me I can tell you what to replace. The capacitors do need to be installed with the correct + and- connections, note the stripe on the old one and insert the new onethe same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping.

Water spill on my AOC2216Vw LCD Monitor


Hey man, thanks for coming to me. Um yea, massaging may help but too hard will do damage since it is LCD is Liquid Crystal Display and it is fragile and easy to damage. The water should clear up in a few months, if not i would look at replacing it which can be costly. Here is a link to fix your unstuck pixels

http://www.wikihow.com/Fix-a-Stuck-Pixel-on-an-LCD-Monitor]

Now im not liking that bit about how you mentioned was spreading so leave it for about two days, give the therapy for the screen a try and let me know if the laptop screen is healing. For the moment if you have one i recommend you hook up a VGA Monitor, old school stuff if you can and give the LCD a rest. I will post as a solution but comment back and i will keep helping you as much as you need it.
