The case has 2 plastic snaps en each side as well as 3 snaps at the top
Use a flat-head screwdriver in the **** between the gray and black plastic. Twist the gray plastic away from the black plastic, and this will snap the part appart

My Monitor is blinking in side. How to solve?


Hello mrakmed,

Welcome, and thank you for using FixYa!

To answer your question: Your issue is one of three things, that will have to be checked and tested by a professional TV Repair Technician, if you consider this worth fixing.

1. Bad soldier joints around the Flyback Transformer.
2. Bad soldier joints around the 5v low/high power supply Transistors.
3. Some or all of the parts above, could be weak, and need replaced.


Have a great day!

A menu keeps flashing on my monitor so fast I can not read it and it will not stop. Black box with grey edge. Compaq 5017M monitor


mrsrobins849, if monitor manufacturing date (on rear of unit) is anywhere close to 2003-2004 then trade unit for new wide screen only if problem of flashing "menu" goes away when you connect a borrowed substitute monitor to your pc. Will your monitor "act" same when connected to "known-good" "fully-booted" pc that will display the WIN-desktop?? Most problems with "cold-cathode-fluorescent-lamp" "back-lit" lcd monitors can be attributed to their internal or external "switch-mode-power-supply" DC voltages degrading over time with use.

ysm7862001, Monitor has possible problem lighting-up cold cahtode fluorescent lamps that provide lcd panel with white light from rear(reverse side) of the panel. No white light= black or blank n black screen. Read my fixya profile for all options you might have open to you.

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

When I turn on my computer, i can hardly see a thing.


Problem is with the backlights. They are long fluorescent tubes usually on the top and bottom of the lcd screen. Most of the time the inverter (the small board that develops several hundred volts to power the light) has failed.

Failure of inverter can (but not always) be helped along with weak florescent (cold cathode) tubes. (caused by use, old age)

Monitor not working...sorta


I just changed my video card and after turning up my screen refresh rate (Hz) my monitor started doing the same thing. Monitor worked great for a long time but now its done! The only thing I can think of is that it has to have 60Hz, turn it up for gaming and its too sensitive to frequency. By the way, mine will turn on after a few power cycles.
