Question about Sony SDM-HS73 17" Flat Panel LCD Monitor

1 Answer

Problem with powerup for my screen

If I could get the screen to work there are no problems unit functions great. When I turn off my computer and the screen goes into power save mode it doesnt come back on. The power light stays yellow (which means its in power save). I have to unplug the unit for a 30-40 secs and then plug it back. Doing this sometimes doesnt help. some of the time I have to plug and unplug about 100 times to get it to work. I think it might be the power unit but who knows. When I use a different moniter i dont have any problems. If you have any info please e-mail at [email protected]

Although you didn't list your operating system, I'm assuming it is Windows and offering a suggestion to clear up the issue based on that OS. Go to settings, and then to control panel. Once in control panel look for "power settings" and click on "custom". This will allow you to turn off all power saving modes by clicking "never" on when the screen is turned off or goes to sleep. If the issue is caused by the power saving mode, this will end the problem.

SOURCE: Sony SDM-HS74P/S 17 - Monitor won't stay on the right picture

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: 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.

It's a common problem with sony hs75p
the problem is with the power board's transistor in the monitor

people might try some stuff and may get some results, but trust me it's all luck...

i had the same problem, so i gave my monitor for repairs as it was under warranty and the culprit was the power board (sony calls it the 'A' board). The only problem is u need to have patience as u are dealing with sony here >_>.... i mean, i got my monitor back, but after 2 tries and with many dead pixels and analog signal being greenish...well atleast the DVI port worked fine >.>, which they said wasn't their fault ( i was like...riiiight, so the dead pixels generated all by themselves, huh?..btw if u are wondering...before giving my monitor...they checked the monitor and it's written in the receipt that the monitor had no dead pixels).... so dont be surprised if ur monitor comes up with another problem, after giving ur monitor for repairs to sony >.>

in any case it's 'A' board problem

WYSE 50 beeps at turn on, but no data on screen. Seem to recall that you could hold down some keys when powering on, but do not recall which ones.

On powerup, you can get to options screens by pressing one of the F-keys. It varies between computers, but it's usually either F2, F8, or F12. If in doubt, try all of them until you get a menu screen, then go from there. The beep at turn-on is an indicator that something isn't hooked up right, usually, so recheck all your connections, then take it from there. If you still have your manual, it will tell you the powerup options, and how to access them. Good luck!.

Boss BV9055 Power Up Problem

12/29. I actually figured this one out myself after reading posts concerning parking brake over rides. It turns out that the Boss BV9055 will not powerup if the pink parking brake wire from the units wiring harness is not grounded. Once I grounded that pink parking brake wire the unit did power up.

Magellan roadmate 700 "powerup problem"

I had a Roadmate 700 with the same problem as yours, and the solution was simple: the hard drive inside had come loose!

All I did was open up the unit (4 screws on the back and a small snap-together clip on the end), and plugged the hard drive back into the cable. The cable has 2 black posts that fit into the hard drive, so you can't misalign the pins. On mine, the hard drive label was facing UP.

Once the hard drive was plugged in, I powered up, and could hear the hard drive spin up (which I hadn't heard before). The unit booted from the "Magellan" screen right into the menu almost immediately!

Hope this helps someone!!
