Question about Sony SDM-HX93 19" LCD Monitor

Open Question

Dead monitor Before completely going dead the monitor would intermittantly go blank (working fine then go black also no pwr lite) approx 5 times within an hour. The black out time was approx 1-2 sec's then return to normal. Today it went black and stayed out! Things I have tried: (removed covers) 1) Internal AC fuse is good 2) removed and re-installed all cables to the power supply 3) removed pwr/spy pcb for close inspection then twisted or flexed the pcb and re-installed. 4) found the +12 & +5v outputs but measure 0v dc Willing to try most anything but stuck as what to do next!

When the screen turns black again take a flashlight and shine it in the bottom left hand corner where the Windows Start button is located. If you can see a faint image then your back light is failing. If that?s not the case the next step would be to attach another monitor to your computer to see if the problem disappears. If it does that points to the monitor, if it doesn?t then we need to take a look at the computer itself. Let us know what you find out and please don?t forget to rate this posting.

SOURCE: Black screen after 1/2 second power-up of Sony SDM-HS73

bratty, do you have a pic on which capacitor this is? Also where I can find a replacement one.

My monitor is doing the same thing, nice and bright for 1/2 a sec then goes super dull, you can barley see anything.

SOURCE: Sony SDM-HS73 Not Staying On

The problem is with power inverter, usually the capacitors go bad and need to changed, they might be bulged and or leaking. Very cheap fix, less than a buck apiece and an hour with a solder iron. Google it to find more info.

Vizio TV model # E321VA turns on and after approx. 5 seconds screen goes black and backlight remains on?

In my whole career as a tech, I never had a defect on a place I would have wanted it. And believe me, if an integrated circuit is defect, or even a diode, you won't see it on the outside of the component. Most of the time you need more than just a multimeter. Any way, to use it, you at least should have a diagram pointing out what voltages you should measure on what point. If not it is pointless.
Be aware even the 120 volt AC, can be deadly, so don't play around with that voltage.

Dell 1800fp dead

Each monitor has a different response to "no activity" from the system. So for the monitor, if you get a chance, try your monitor on another machine that you know does function. At work, neighbour, or other.

For the computer, does the it (beep) or POST (Power On Selft Test) when you turn it on, do you see and hear what you would if the monitor was connected?

If it sounds normal, then everything should be fine and luck might have it, your backup monitor is not working either, try another one from the same friend or neighbour above.

If it doesn't POST, you could have a video or other card or ribbon connection loose in the computer. Either you or a friend, or the service center, whichever feels comfortable reseating all the external and internal equipment, bearing in mind static electricity and proper handling measures for the computer.

Dead pixel

It might, somes companies won't honour warranty unless you have 3 to 5 dead pixels. Go to and contact customer support to see what can be done.

Iiyama E2607WS just stopped working - completely dead - internal fuse OK

In most cases there are one or two capacitors in the power supply that open, and in some situations they have a bulge at the top making it easier to spot.

Sounds like your monitor is going dead. If its under warranty that would be the best way to go. Specifically it sounds like the power inverter is dead or there is a busted capacitor.

Blank screen - appears to be dead

If the screen is completely black, your screen may indeed be dead. There are a few solutions you can try before throwing in the towel though.

1) Test the monitor on another PC if you can.
2) Make sure the contrast, and brightness aren't turned all the way down.
3) Make sure the graphics card in your PC is functional. You can easily test this by connecting a known working monitor to your computer.

If these steps do not resolve the issue, and your graphics card is in good working order, you indeed have a dead monitor on your hands. It may be cheaper to buy a new monitor, than to have that one serviced.

Monitor went black completely dead

A simple way to check your AC Adapter, plugged into a socket and see if it lite green... If you don't see a green light lite on the AC Adapter, then it's DEAD... You can order the AC Adapter @ but sometime you need to replaced both. Have a nice day!

I had the same problem for about a week and solved it yesterday by downloading the latest driver by NVDIA who makes my video card (NVDIA GeForce 6200).
I had previously updated the latest Sony driver for the monitor. It did not solve the problem but could be part of the solution in conjunction with the new video card driver.
