Question about Sony SDM-HS73P 17" LCD Monitor

2 Answers

Sony Monitor ... SOMEONE HELP, please!

I own a Sony LCD SDM-HS73 Monitor, its almost 4 years old. Never had any problems with it until now. When my computer has been turned off for awhile, and I turn it back on, the monitor green light comes on, but the screen is black. I have to uplug the monitor from the power supply, and when its plugged back in, everything is fine. So, I took it to a repair guy. He replaced the G board, and had the A board rebuilt. $195 later, I bring it home, and nothing has changed. I am going to do the flashlight test, but I am trying to find out if the "inverter" board is the G or A board, because I think this guy just ripped me off. Any help would be great. thanks, ann*e

    thanks Tigers02...
    I had a feeling that was the case. I did the flash light test last night and couldn't see anything (so its not the bulbs that are going bad), now i just need to try and get my money back from the guy that ripped me off.

    I WOULD STILL LIKE ANY OTHER SUGGESTIONS from anyone that has them.

    SUCH AS... in another post someone mentioned the "invertor" board going bad when you have symptons like this. I am trying to find out which board that is. I had the G board and the A board replaced in my unit, but don't know if either of those was the "invertor" board. I called sony customer service and the parts dept and technical help... NO BODY could tell me which board letter was the invertor board.
    I don't think i'll ever buy sony again.

    Sony SDM-HS73, experiencing same problem. Power light changes from amber to green when coming out of sleep mode. Screen will turn on after unpluging power cord and reconnecting power cord several times. At times the sceen may turn faded blue or white. Once the screen is operating it works fine until the PC is shut down or goes into sleep mode.

It's funny when reading sweetanne post on her Sony LCD SDM-HS73 Monitor which I also have ,I could copy her word for word ( I own a Sony LCD SDM-HS73 Monitor, its almost 4 years old. Never had any problems with it until now. When my computer has been turned off for awhile, and I turn it back on, the monitor green light comes on, but the screen is black. I have to uplug the monitor from the power supply, and when its plugged back in, everything is fine. ) Only mine does come on but it takes anywhere up to 15 minutes to come on and I've noticed with the green power light on I cant press to shut off unless I'm shutting the computer off.. Sony was no help gave me a number to call so I called it and yes up to $200 to fix if they can so for the time I will just have to put up with this. :-(

Thanks for your response. I actually sent my monitor out to guy that does LCD repairs for cheap. He changed out the video board and did repairs similar to yours but still couldn't get the monitor to work. After some more testing, he found that one of the chips that contained Sony's proprietary firmware had gone bad and said there really was no way to replace the chip. It definitely seems like we had the same problem, so I thought this information may help. I'm sorry that you paid so much for repairs that didn't solve the problem.

17" Sony SDM-S74 goes blank after 1 hour

Here is my possibility.

Sorry to be the bearer of bad news but the fact is you have a very old monitor. My research tells me that it is almost 10 years old.

The obvious problem and the one most likely is that the power board inside the monitor is going. It is common in LCD monitors of this age. Do yourself a favor and junk it and replace is with a new larger better monitor. They are so much better these days and so much much cheaper.

You can get a 22 inch wide screen monitor on right now for $104.00 and pick it up at your local Walmart with free shipping. Not advocating Walmart necessarily just pointing out. Recycle your old monitor responsibly and pick up a new one. No matter how cheap it is it will be better than what you have now and your current monitor is not worth a technicians time.

If you don't have the money for a new one go to your local thrift shop and get a working 17 inch for $20. Good luck.

Had my monitor for four years, great performance

jlallen54, When lcd panel goes to a dark condition please shine a bright flashlight 1 inch from screen an tell me if screen data is still displayed during this "blackout" condition. It might be just a single (1) poor and now thermally intermittant solder connection on the printed circuit board inside the monitor. Do some reading first and then you will understand the problem that your monitor has. 12fixlouie

Monitor goes Black off and on .....

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.
