Question about ViewSonic G790 19" CRT Monitor

1 Answer

Have no sound

I inherited a ViewSonic G790 19" CRT. I hooked it up to my hp pavilion a510n without any obvious problems. Everthing seems good, but i have no audio. My only previous experience is with my old hp pavilion m50 monitor that had external speakers that hooked on the side of the monitor. What do I need to do to get audio with the viewsonic g790? does is even have internal speakers? sorry such lack of knowledge! any suggestions?

Moniter no display but power ok

as a computer technician by trade i will the obvious and move through to the complicated procedures and if after this you have no luck it is dead
first is there a video signal coming out of the computer
second is to video cable (vga) still good
third do you hear a crackle or obsesive humming while in operation(if yes disguard imediately)
lastly does the screen change shade when turned on (if yes you have a video problem)
and remember if it did not meet these criteria then disguard imediately as dead crt monitors can be very dangerous or harmfull should it blow out.

hope this helps and good luck

Speaker in the Monitor?

It looks like there are no speakers according to:

You should be able to use any external speakers to your system. The question is looks and power. You will likely have to buy speakers that have power in order to get enough volume.

Most speakers that come with monitors are of very, very low quality. You now have the option of buying good speakers (if you want to pay for them). If you are in a hurry you can likely pick up cheap speakers at the drugstore or Walmart. Another option is headphones.

Good luck finding the right sound.

Unplugged monitor at one location and moved to a different location and the monitor will not work..... Tried a different monitor into the same PC and it worked fine. Viewsonic continues to go into power...

Sounds to me that it's a resolution problem. I think that the previous monitor that was hooked up to it last had a different resolution.

That or try restarting, it may need to install a driver.

Viewsonic P225f CRT - clicking "short circuit" sound, shrinks and expands

Just on a whim I'd say open er up and dust it out , and look for bad solder joints.

That means get out your soldering gun and have a look around the board.

what you described is "intermitant failure" sparking sounds , that prety much indicates a bad solder joint some place , not dirty power , if you suspect dirty power , you can buy a little UPS voltage regulator 6 outlet , those little things can really do the trick when it comes to dirty power because
they can regulate the voltage ALMOST like a full blown UPS backup unit without the battery.

You sound like a smart person who understands power has to be clean , and you seem to understand that intermitant failure is like performing a ( shock test ) where you actually tap on the
device to see if something is loose.

if something IS loose thats like saying open circuit , so that means get in there and have a look for a bad solder joint , I'll bet dollars to donuts it's a bad solder joint at the plug of the monitor , thats because thats where the point of contact is with the power cable , and we tend to wiggle the power cables on our monitors which causes arcing and sparking , if you get my meaning.

I have every confidence you can trouble shoot this problem with just the simple things I've told you.

Go get em tiger.
