SOURCE: instructions on how to disassemble and fix a Viewsonic VX2235WM

Picture tube is not major problem. It is the main board, having damaged capacitors, could be more then 1. Other components to look at is, high voltage tranisitor, which gives up in most cases. Most cases in my career, i found that monitor tubes are good, unless the are dropped. So resolder the main board and check out for the components i mentioned. Careful while repairing, it has high voltage, take all precaution while openining the panel. Unsrew all the screwsat the back, also the stand, take a flat screw driver and lever the panel from one end till you open all the 4 sides. Thanks, and don't giveup.

SOURCE: Viewsonic VP2030b LCD monitor - No power

There should be one fuse in the power supply inside. You can check and replace that if its dead. now if its not dead and you got power to that point you do need to rule out any capcitors at that time but if the fuse is gone it will not hurt to check the rest of the supply for the fault.

Please rate and accept the answer if it did help.

I would make sure that all the cables are securely connected to both the monitor and the pc computer (screwing the screws from the cable to the port will help hold the cable in). Beyond that, the issue is likely with the monitor and not something that can be fixed by the end user.

If the device is still in warranty (and checking the cables don't work). I would recommend sending it back to ViewSonic to have it fixed.

Yes you can if you can source one however it may be more cost effective to replace the monitor.

SOURCE: ViewSonic VE170b 17" LCD Monitor Faulty power

You need to check the fuses on the backlight inverter board, also the logic board may be damaged by the AC voltage.

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 monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

How to disassemble?


pankaj29, A 1 to 2 hour visit to YOUTUBE may help!!!! Search using "lcd monitor disassembly" and "lcd monitor repair" just for starters. Lot of video clips that will help you "part" the fromt "bezel" from the rear "cover". Do not use sharp cutting instruments for prying!!!! One careless slip and it's off to the local hospital "ER" or maybe call a mortician!!! 12fixlouie

I have two Viewsonic VP2030B monitors that both died together. Possibly a resolution or scan rate problem but I need a bit of help disassembling the things. The main chassis seems to be held in place...


wa7tuv, If the plastic front "bezel" is very thin and the monitor control and setting buttons are located on the verticle sides of unit, it just may be that the "bezel" will need to be parted from the rear cover, with the glass lcd panel left in the rear panel. Then you will need to remove screws so you can get lcd panel out of the rear cover. You might just get lucky and find a video of some owner/technician doing a tear-down if you search YOUTUBE using "lcd monitor disassembly" or "lcd monitor repair" as search terms. Be very careful and protect the glass lcd screen at all times. It is the most expensive part of the unit. You CRACK the glass, It's you bought it, you own it, Toyota!!!! You could also check with Viewsonic to see if they have a cash+old unit exchange program for out of warranty,but prematurely failed units that will be swapped for same model "refurbished units????? 12fixlouie

ViewSonic VP201b with a black screen


hramirez, Retevo. com says time to retire this old monitor. Its that or you will need to do some extensive reading here on fixya on how and what to look for inside the unit that could be causing your black screen condition!!! Then you will go to YOUTUBE and view some of the many video clips that deal with "lcd monitor repair" and lcd monitor disassembly". Have you noticed any bad, swollen top, elcetrolytic filter capacitors on the units "switch-mode-power-supply/CCFL inverter printed circuit board?? How about any "cold" frosty looking solder joints around the component leads of the power transistors and ferrite inverter transformers? May need to get large magnifying glass to find those pesky little cold solder joints. 12fixlouie

Dead on arrival need to open back cover


emtv_satc852, First visit YOUTUBE and watch some of them being pried apart at their perimeters around the four edges. That's how most of them are opened. Some people use an old CD or DVD disk, while some use thin blade screwdrivers. Try "lcd monitor disassembly" or "lcd monitor repair" on YOUTUBE. Good luck. Hope this helped. 12fixlouie
