Question about ViewSonic VP191b 19" LCD Monitor

1 Answer

Flatron L1932TQ i have this LG moniter and it has worked great for a year now. Last night thought my moniter was on yet it wasnt on. I turnied it offthinking it was hot then tried it back after a few minutes and it came on long enough for the analog message to appear in the top right corner, then it went dark. Thing is i can varely see what is still going on on the screen from a side angle. when i try to change the source by pressing the source button it flashes to the analog where i can see it great, than back to dark. coiuld you guys tell me what happened and how to fix it, it isnt the power supply and it isnt dusty or hot. Thanks

    I have the exact same problem as the original poster. I've tried so many things to get it to stay on, and I think I have found a solution (at least until I can afford a new monitor). If you know which f-ENGINE setting you use, hit the f-ENGINE button once to bring up the selection screen (even though you can't see it) and navigate with +/- to the Normal setting and hit AUTOSET. I used to use the Movie setting on the far left, so I just hit - (minus) once to get to Normal. If I try to use any other setting, even User, it goes black again until I change it back to Normal mode.

    I have a similar problem with my L1932tq Flatron Monitor. I'll be puttering right along when suddenly the screen will go to black, and I'll see the [Analog Power Saving Mode] message. No banging of keys will bring my screen back to life. I have to re-boot. I can go for days between incidences or there are times (like today) I've had to re-boot several times just to research this problem. Now and then it will go into power saveing mode even before boot up is complete. I have the monitor set to never go into power saving mode in windowsso that is not the problem. This Monitor is only two years old.

Sounds like your inverter is going out. It is pretty cheap to replace if it is modular, ie. if it is a seperate plug in pc board. I parted out a 19 LCD because the inverter was integral with the power board and was not economically practical for me to repair when new ones are 169.00. also look a the capacitors (look like little cans with crosses on top) on the pc board. If any have bulged or blown their tops, you can try to replace them at about .50c a piece and a slodering iron. Just get the correct value, voltage (higher is OK) and temp rating (higher is OK too, but they are probably 135C anyway)

My LG FLATRON W1934S was working fine last night. went to turn it on this morning and nothing happened. no orange or blue lights and it wasnt left in sleep mode either. what could be wrong with it?


I would suspect a problem in the monitor power supply, either a fuse or possible bad filter caps especially if you had to turn it on several times to get it on just before it failed.

If you are able to open it here is what bad caps look like:

Your new moniter may not be compatible with your computer. I have an Emachines that won't take a flat screen. I have to use a big bulky moniter because it says not connected even thought the hookup fits the back of the tower. That might be your problem. Did your old moniter work correctly?

S.R I HAVE COMPLAINT MANY A TIMES BUT ONO RESPONSE FROM LAST 15 DAYS .MY ON/OFF SWITCH IS NOT WORKING PROPERLY


the best way to test this is to hook another moniter up and see what it does. if it works then the flatron is junk and needs to be broken with a bat in many pieces

Monitor keeps shutting down into power save mode? Its a LG Flatron L1932TQ-BF. Turn it off then back on it comes on for a breif second then shuts down again?


This happens when the capacitors (680uf/25v & 1000uf/16v) on power supply board are blown.
