Question about Sony SDM-HS73P 17" LCD Monitor

1 Answer

`my Sony sdmhs73 comes on for 1 sec, then goes to power save.

Plugged it into my laptop and did the same thing, so it is the monitor which is only 5 yrs old. Is this all I can get out of this monitor? Maybe need another brand?

The caps (capacitors) in the powerboard are going out. This is a very common problem in all class and price ranges of modern lcd and plasma tv's/ monitor's. I don't know if this problem has been like this for awhile or it just started, but either way, if the tv takes an abnormal amount of time to "warm" up then it most likely will go out all the way sometime in the (near) future. If you have a tiny bit of will and knowledge ypou can open the unit and get to the print board. Examine this for "popped" capacitors, they will have a buldging top instead of a flat one. Im gonna try to include a pic of them here, if i can get it this time, I've tried bfore lol. But you can google image a "popped" or "bad" capacitor and you would be able, with ease, to diagnose if you have any of these. Usually only one or two. Radioshack sells capacitors (couple anyway) for $1.59 each. MAKE SURE the replacement is of the SAME voltage or HIGHER, or you will be right back replacing those 2. Every capacitor has a negative pole marked with an (-) on the side of the capacitor(by one of the "legs", always puit the negative (-) "leg" of the new capacitor in the same hole in the printboard as where the previous negative (-) "leg" of the capacitor was ( a capacitor with the negative and positive "legs" put in backwards will result in the new piece "popping" as sson as you turn it on!!) make sure the "uf" rating (for example the most common popped capacitor is the 1000 uf) is the same as the one you are replacing. I needed 1000 uf, 105 c and 26v (volt) ratings for the 1 capacitor I needed to replace to fix my LG 19" lcd panel monitor I found by the trash that the light came on off, but it didn't come on. I replaced that capacitor with ; 1000uf, 85 c and 36 v (volts0...It works fine eventhough the volts and the temperature rating (36v and 85c) was not the same as the (26v(volt) and 105c ) capacitor I removed !! Further, I've replaced capacitors that had the celcius rating of 105 with the only ones Radioshack had, namely 85 c(celsius) they have been working great, but I'm not sure about any effect, nor have I heard or read (yet?) about that making an urgent difference. Many threads that I've read people have done the same, so we should be ok (my stuff has been running good for a while longer then most brand new ones!.............(all these ratings ; 'uf ' and 'c' etc are on the side of the capacitor you are replacing and on the side of the ones you are replacing them with)...For all this all you need is the cheapest solder gun u can find (I bought one for $7.99 at Radioshack), a camera (to take pictures as you go to remember how to reassemble the unit) and, once you have your materials, 20 minutes to replace 2 or 3 capacitors and you are good to go...Most monitors and tvs (lcd/plasma) I've seen you have to lay flat on the ground/bed/blanket etc, to work on (screen side down). Usually there are 2 or 3 screws (or a few more) to remove, then you will have to carefully (its comes off easily most times)insert a flat screwdriver inbetween the casing and gently pry it up as you go around the whole frame. Sometimes you have to remove the little washer arouind the cable input orso, just be gentle and you cant go wrong. Once insidet here will be a box with wires running to the sides etc...unplug, gently, these wires and open the box. Inside you will find 2 or 3 circuitboards, check them all for "popped" capacitors, replace, reassemble and plug it in....Have fun becoming an overnight tv mechanic lol! If this helped any(or not0please rate, thank you!`my Sony sdmhs73 comes on for 1 sec, then goes to  - 11a86db.jpg

Franciso: Have you tried using your laptop power adapter without your battery being in? You will save alot of money just using your power adapter when you are at home without your battery being in your laptop. I hope that you have a cooler fan under your laptop because it will help your laptop still cool. If the adapter doesn't help you will have to reinstall windows and load your programs again.

When I plug the monitor it won't stay on. Why?


1. CRT or LCD?
2. Do you have an image of any kind for that 45 sec.?
When it drops out after 45 sec, do you have any strange behavior as you look at the screen (colors, blinking, lines, squiggles, noises, smells)?
3. When failing, does the power drop out (ON light goes OFF)?
How long do you need to wait until you can turn it ON again?
4. What is the status of your screen saver/power saver? 45 sec seems pretty short but it's still possible.
5. What does the manufacturer's website have to say about this problem? What do other users have to say when you search for your model?

I know these are just more questions but your question is too generic to offer specific comments that might be more useful.

Viewsonic monitor stays on for only 3-5 minutes and goes off . Then I turn it off an wait and it comes back on!!! what is going on??


I guessing that when you say "goes off" you mean it goes into power-saving mode? Assuming that you're working on the computer at the time (so it's not actually going to power saving mode from inactivity), this might indicate one of two things:
a) the VGA cable to the computer is not in a good contact with the monitor. This might happen if you haven't used the screws to fix it in place, just try to plug it fully in on both ends (computer and monitor). If the monitor sees to VGA signal, it goes into power saving mode automatically.
b) there's a problem with the monitor that builds up after a few minutes. When you turn it off, it "cools down" and can be used again. If that's the case, you should take it to a dealer's shop and have it checked (or replaced if it's still under warranty).

Cause If you connected the monitor power already is on, you may not get signal. Power plug off the monitor first, Then connected to laptop. Then power the laptop and power the monitor. FN key press hold with your Monitor swicthing key which symbol of two monitor shows on key probably number 5 or 6 maybe 7 check user guide if you have it.
another cause is your monitor may need driver install in your laptop, Some system required that. Check monitor system requirements.

ViewSonic VX910 monitor has a power supply issue.


Your monitor have a bad condensator in the PSU.

The only thing to do is to replace the Power Supply Unit (very expensive, more than a new monitor) or if you have electronic tools, found and replace that condensator.(cheaper way...)

or

Have you connected your monitor with a new power cord ?

Best Regards!
