20 Most Recent Soyo TFT 19" LCD Monitor Questions & Answers

This is typical with many sets when it goes old as there is a high possibility that the components over a period of heating and cooling , tend to bring on a problem of dry soldering. So my advice is to check the set for some loose joints that have played on to give you these erratic shut downs.

Remove main plug, the covers - with caution of high voltage, check for dry joints, use a good soldering iron to solder all suspected points. Please find below two links for tips on poor start ups, as if the set is totally failed the SMPS might be faulty

Soldering tips:

Slow start of circuit

You may have dying power supply due to bad DC filter caps.
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/home/budm/allalbums

Hi


Thanks for using FixYa. To start with if you have warranty then use it and get it repaired to avoid future issues. However, if you dont have warranty then you can open the monitor and start checking the power board which is the board where power cord/plugs goes in as it seems you have checked everything else out. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks

If it uses AC adapter, then check the DC voltage at the DC plug to see if you get any voltage, if it use Direct power cord then it may have blown fuse inside the monitor, then you will need to open up the monitor.

your power supply is bad or the back lights. you need to open the back cover and look for leaking or crown capacitors and replace them.

check power cable and change if needed.

Your monitor is failing due to age.

Either the cord isn't hooked up, a pin is bent, or the computer isn't sending a signal. In the last case, you may need a new graphics card.

Go to Device Manager - locate your monitor - delete it with drivers - reboot the system

this can be your computer issue not monitor try connect to other monitor and make sure your computer is working fine ,you can check all the lights on the computer are on and getting no beeps sounds usually you will hear a single beep when PC is booting well

you install a application in your pc application name is " realtek audio driver

screen n T-con faulty replace them

Out of range indicates that you have attempted to use a resolution the the monitor is incapable of handling.

Lower your resolution and try again until you can get it to do what you wish then try to do each monitors resolution individually.
