Re: benq7t3

Open up the FPD and replace the Power supply or if there is a small inverter, replace that. And it should solve your issue.

Wish you luck. I've fixed this problem so many times. I hope its not too late to solve your issue. Please Rate, Porfavor.

Open lcd 17 power supply 5volte ok 13 dimming

First of all you need some electronic repair experiance,
You have to disconect all f the power supply that going on 5v(rgb processor in moust cases)and 13v in most cases ccfl inverter(back lite ) with his driver.than have to mesure the voltages.
-Replace the capatitors in 13v line.
if the problem persist try to replace the diode one for 13v with one for 5v,they should be the same type.and check the voltage 5v and 13v.
if the problem is still on 13v look for the problem on the 13v line.

Monitor come on for a few seconds then goes black,green signal light stay on green. can you help

the monitor may be losing the back lite. take a flash light or bright light and shine it at the screen after it goes black. can you see a faint picture? if so the back lite has failed. usually the cost of replacement exceeds the cost of a new monitor but there are a couple of web sites that detail the replacement of the "ccfl" cold cathode flouresecent light.

Black screen after a year of use

Sine a flashlight on the screen and check for a dim image. If you see a dim image the back light needs to be replaced. After doing that you will want to try using another monitor cable and see if that helps. If it doesn't with the computer on and the monitor on disconnect the cable from the computer. If the monitor shows a no signal error the graphics card needs to be replaced.

Computer Monitor is dim

mzsouthpole9, Yes, this sounds exactly like a SWITCH-MODE-POWER-SUPPLY problem, and/or INVERTER circuit problem. I have lucked out and repaired 3 lcd/fpd monitors with very similar/same complaint. Now here is what you are dealing with. Have you seen the new energy saving 'curlie-Q' screw-in Compact-Fluorescent light bulbs? Your lcd monitor needs white light to light-up all the pretty colors in the LCD panel. You are lucky. The SMPS in your unit is at least for now, supplying voltage to the digital processor board in your monitor. That's y u see an image on the screen. Because your Cold-Cathode-Fluorescent tubes (2ea) are not lighting-up, you now see what you see. this most likely is a SMPS failing to source voltage to the Inverter circuit which takes 12-20v dc and changes it to 800-1500v ac to light the thin, straight, horizontal (left to right) CCF TUBES. Here are your options as a consumer. Call viewsonic, see if they have a swapout program. You send them your's+$50-$90, and they send you a refurbished same model in return. Or try to find local TV/Monitor repair shop that knows forwards and backwards everything about CCF tubes and SMPS/INVERTER repair. Last thing is try to repair it yourself. Whatever you decide to do, please drop an email to me. I'm louie12fix on fixya or lmistyrel@ Hope this info was of some help. PS Put LCD/FPD in safe place to prevent damage to the most costly part. the LCD panel!!!!

Monitor stays dim

Chances are it's not the actual CFL back-light bulbs themselves, but the back-light inverter board. If it was the bulbs you would have not had the "warm up and it get bright" issue. The board IS replaceable, (as well as the bulbs) ViewSonic charges about $36.00 USD for the board when they have them in stock. (out of stock as of yesterday 11/14/2006) It should be covered under warranty if you got longer than one year. (I know the warranty was only one year on MY VA800 but I have seen longer offered since i got mine) Good Luck I hope this helps! El Duderino
