Common problem in the HS73/93 is bad soldering works in the lamp assemblies, see my pictures here:

But look for bad caps (leaking/bulging top) first in the power supply section.

Screen goes black while power button is on i turn off power to monitor and it will stay no a few seconds and go black once again


Common problem with is SONY 17" and the 19" are due to fail lamp assembly as shown in my pictures here which will be the worst case. You will need to check the other parts in the set first.

My sdm-hs73 moniter the power is on but screen is blank, what could be wrong


First check brightness and contrast settings.
If all good could either be your lcd back light has gone or the inverter. To check if its the black light shine a torch through the back of the screen to see if you can see a slight image on it, if you cant see anything the inverter board is faulty and to repair needs to be changed.

Sony SDM-HS73 Monitor huts down after 15 seconds..


Hi...there,
Well, open it up and look for the capacitors voltage (example 1000uf 16v). You can get it in any of your local electronic repair shop or radio shack.

SDM-HS73P Screen Flashes


This is a problem I have seen with a few LG monitors.
Your Inverter circuit is fine (that powers the lights to your screen so you can see the image on the LCD panel) but the monitor does not like having a video signal attached to it.

  1. Bad capacitors on the power board can upset the current going to the controller board. This board included the video input circuit and the power supply needs to be stable for this to operate.
  2. The controller IC that translates the video signal into what the LCD panel controller can understand is failing. Normally this fault occurs in the horizontal and vertical input of the IC. The fact you can see the other message on screen is due to it going through it's own internal and seperate section of the IC. In this case the only repair option is to replace the internal video board. Sony will not supply the parts directly to the public, but if you are really nice, they "may" tell you where to get one externally to Sony.
Hope that helps =)
