SOURCE: My sony monitor flat LCD HS74P went black and heated up

Its easy to repair. Some parts that needs replacement are the blown and bulge capacitor in the power supply section on the monitor. They are the very first to be affected when something goes wrong. The others where the inverter transformer and the inverter light. Very cheap to repair, the labor is the one that cost that much. Bring it to a nearer technician in your area and it will be repair in no time

Hi, I have a ViewSonic VX2235mw LCD Monitor it was working fine then all of a sudden the screen turned off and now it wont turn back on. The power light is on and is Blue but no sign of life in the screen...


This is a very common problem with this model after a few years of use. This problem is caused by a failure of the capacitors in the power supply board hat powers up the back lights in the monitor. When the back lights don't power up you get no display on the screen. Here is a link to a repair guide for that model that shows how to open the unit and what to look for and replace to repair the monitor.

Here is part one of the three part video repair guide posted at the above link:

The Samsung 204B monitor have a know issue with failing power supplies that cause the exact problem you are having. At first they are a little slow to display a picture and the more you keep using it the longer it takes for the display to come on. The repair is simple if you can solder. Here is a link to a site with additional information on this repair. This Samsung 204B monitor is a great unit with a simple to solve issue. No need to trash a good unit.

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

I have a 5-year old Sony 19-LCD monitor that stopped working. The little power-on light does not come on, and their is no picture, but I do hear a faint buzzing from the back. Sounds like?

smyko, Sounds like a tired out old "switch-mode-power-supply"/ "inverter CCFL power-supply!!! May require unit to be REFURBISHED with upgraded power suppllies and if the LCD screen had been displaying an increasingly dimmer screen, it may also need new "cold cathode-fluorescent lamps" installed. A technician who knows all about LCD monitors and their backlight "ELECTRONIC BALLAST" circuits will need to evaluate it. Check with sony and find out if you can do a "cash+old unit swapout for a factory rebuilt (refurb) same model type. Before you do any of that have a look at youtube for longer video clips of "LCD monitor disassembly" and "LCD monitor repair" just FYI. You will then know and understand what is on the "OTHER SIDE" of what you been looking at for 5yrs!!! Yes, they are trying to experiment with WHITE led arrays that won"t fail for 10 years. Remember lcd Panels last 8 - 12 yrs. Hope this helps. Bye for now. 12fixlouie

Sony 24'' CRT widescreen GDM-FW900 blurry after initial on

CRT shorts are common with this model and focus problems are a major symptom. however, the loud 'pop' you described leads me to believe that the flyback transformer may have a problem in the focus divider portion. replace the flyback, if that fails then the CRT is most certainly the problem

Acer Monitor

I have no idea about the game connection, don't add to many questions to this, as you can research that stuff yourself as you are now a expert in your own eyes. There is a driver for that monitor located on the Acer website and they offer a 3 year warrenty on the monitor. I doubt the driver will fix your issue, but it is at least worth a shot.
If what you say is true, then it looks like to me you've tried just about everything that can be tried and I would lean toward explaining to Acer why you need a replacement monitor.

Compaq 1501 15" LCD Monitor ( Blinking Display)

Hi BOY! :P
Check if there is anything wrong with the video input cable to the monitor. If not then you should move ahead with the replacement of the ceramic fuses. There should be around 6 of them in most monitors i have fixed. They will look like this(click here) They should cost you around 1$ each.
If none of these work then your monitor's inverter board is probably screwed and needs to be replaced. should cost you around 30-60$.

Dell LCD monitor suddenly loses power


Five years is a long time for an LCD panel. You definetly got your money's worth.

But, if your trouble shooing has led you to this conclusion I can also only conclude that the power driver inside your panel just gave up the ghost.

However, try giving Dell a call, for what's thats worth and see what they have to say.

You might also want to ask this expert "Robotek" what he may think as he is a board troubleshooter and could give you an answer if one is there.

Samsung monitor 970p triple hinge.. hinge collapsed how to restore

From doing a good amount of internet research I have found that this problem is "fixable". Inside the top portion of the arm there is a spring. That spring was made to support the weight of the screen, but after readjusting the screen so many times, the spring loses its ability to hold the weight. If you take apart the top part of the arm (the top part, not the sides, pop it off with a flathead, be careful) you can fix it a number of ways. I used a zip tie. Go right through the middle. and tighten it until you get the screen where you like it (forever). thats just want i did. Do some googleing people!
