Question about Computers & Internet

1 Answer

Hi, I have a ViewSonic VA1912wb monitor. Yesterday, the screen on my monitor went blank and it never came back again. I checked the power cable and the graphic cable, everything seems fine but still I don't have any picture. I even tested it on a different computer and it was the same. The green light in constantly on and when you stare at the monitor you can see the icons on your desktop and even movement of your cursor, but the screen is very very dark. I would really appreciate it if anyone can help, Sean

Sean, I can't believe you havn't been to YOUTUBE to see video clips of "lcd monitor repair" and "lcd monitor disassembly"!!!! You must have very good "eyesight"!!! You have just performed the "flashlight test" without the aid of a flashlight!!! See the icons=SMPS in partial shutdown mode!!! No see icons=SMPS in full shutdown!!! Ask us tech's more questions here on fixya only after you do web research at fixya and have seen videos at YOUTUBE. Do reply after you find out what WE already know! You might even be able to refurbish unit for less than $8 in new capacitors on the SMPS board. 12fixlouie

It can be the power supply DC caps for the backlight inverter circuits or the inverter circuits have failed, you will have to open it up.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed VIEWSONIC monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Blank Screen


Common problem in monitors are bad caps in the power supply, that is the first place to check, look for bad caps with bulging top/bottom, see example of failed VIEWSONIC monitors due to bad caps here (worst case will be bad lamps): http://s807.photobucket.com/home/budm/allalbums

Viewsonic va1912wb monitor goes blank for few seconds and comes back and this happens very often


Your power/inverter board needs to be overhauled.
Your capacitors on the board are probably burned out.
If you open it up and send me a picture , I may be able to tell you if they are or aren't.
There is also a chance a transistor has gone bad on the board.
I repair many viewsonic boards on ebay

Viewsonic VA1912WB error says analog signal


I had a Gateway 19" TFT that did the same thing.
Does the power light stay on? If so, you more than likely have "dry" solder joints at the inverters. Take it apart & shoot a little solder on the inverter solder joints. Good as new now. The solder joints dry out because of the high heat generated. This is a very common problem.
