LCD monitor gets powered off suddenly

by Harshada321 / April 4, 2013 6:10 PM PDT

I have one LCD ViewSonic - VA1703wb.
Suddenly it gets powered off while working. I have replaced the power cord 2-3 times but still the problem persists.
I think the problem might be with the monitor itself.
Please suggest, whether I need to try for some other solution or put it on a repair or atlast replace it with a new monitor.

From 2008?

Try the usual. Canned air on the vents and if you are a repair tech, open it up and replace all heat sink compound.

LETHAL and DEADLY voltages are inside so you as the tech know what to do now.

Just replace it

While it can be repaired, the cost of repairs and/or time involved maybe better spend just buying a replacement. Now, you have a reason to get the newest or latest LCD out there or one you like. Overall, you can later work on the busted LCD, whatever the problem. I also recommend, being a LCD, parts maybe hard to get hold of and if you're not a tech person, it will be a hard learning experience.

In reply to: Just replace it

We can't give guarantee about such gadgets, even after repair the problem may arise in future.
So, I think you are right...its better to replace it & get the latest one.
Also, I'm a non-tech person. so please suggest me about which monitor should I purchase.

Harshada here's a real solution

Your lcd probably has just blown a component, that's why it functions but not for long.
I'd go to a site called Fixya and the really good one is I think. I fixed this
lcd by soldering in one replacement capacitor. So the 19" I'm using, given to me
because it didn't work, cost 25 cents U.S. to fix, plus gas. Easy and save your money.

Good idea, but...

Capacitors must be discharged before attempting to replace them. Otherwise,

"LETHAL and DEADLY voltages are inside so you as the tech know what to do now.

One to watch for is the main transformer... Best to leave this to one whom knows what they are doing.

Thanks for solution
by Harshada321 / April 11, 2013 3:01 PM PDT is a great site. Thanks for making me known.
If capacitor would be the problem then I think it won't cost much for the repair.
I'll try your this solution. If it helps..good, otherwise atlast I'll purchase a new better one.
