Soyo 19" flat screen monitor

When we turn on the computer/monitor, the picture only appears for a moment then flashes off, if we turn off the monitor and turn it back on, again, shows the screen for about 3 seconds and then blacks out. I have checked the cables/connections etc. any hint on whats wrong. Monitor is just under 2 years old.

    I have the same problem with a 20' Soyo. Monitor reads "no signal." This is an intermittent problem. I have plugged and unplugged the cable between two video ports. I have replaced the cable.

Hi, these monitors are dropping like flys and it's due to power supply problems. There is a power supply that needs to supply 5v, 12v, 24v. The 5v and 12v is for the logic boards and the 24v is for the back light. On other boards people have tried to repair the supplies with no luck (same here).
The best fix is to purchase two power bricks off of ebay. Get one that supply 5v 12v that are used for external hard drive enclosures and get one 24v that is used for mac g4 laptops. Both can be had for < $10. Then you will have to replace the internal power supply with these. This is not for the beginner, but if you have any experience with soldering and wiring you should be able to do it. You will have to tap into the 12,5 volt wires, I used the PC style power 4 pin connections and attached the other end to the power supply. You will also have to do this for the 24 v lines. A bit of cutting / stripping, soldering and getting the AC to both will do the job.
The only thing that this will not do is shut of the 24 v supply during idle. Best this is to remove power from the monitor when not in use. This should fix an no / power / on then off / problems with this monitor.
Total time is probably about 2 hours and tools needed are the replacement power bricks, cutters, soldering iron, solder, electrical tape, screw driver... etc

Does the fault appear on the laptop screen aswell? It appears by your description that the fault is only on the external monitor. If the screen comes on for a moment and then goes blank as described, then this appears to be an invertor fault. It is very common among laptop and tft screens and requires the invertor inside the panel to be replaced / repaired. Simply plug the screen into another computer to confirm.

medproducts, Nothing new here. Check internal "switch-mode-power-supply board" only after devoting about 1-2 hours of viewing "lcd monitor disassembly" and "lcd monitor repair" video clips at YOUTUBE!!! Then you will need to make big decision!!! Let me and all who read this know what your plan of action is.

I have a soyo computer monitor, flat, 19


packldr, If your certain that the monitor is not going into sleep mode, you will need to find out where the possible bad solder joint might be. This type of symptom could be a "intermittant thermal fracture" of a solder joint on an internal printed circuit board inside your monitor. Your monitor works fine until the internal temperature rises enough to cause "thermal expansion" to cause a OPEN connection on some critical component on a "switch-mode-power-supply" or "cold-cathode-fluorescent-tube" power supply circuit. (INVERTER ckt) If you visit youtube, check for videos that deal with "LCD monitor repair" and "bad capacitors", "LCD disassembly" just so you know what you are dealing with. Please let me know if this was helpful to you. I'm louie12fix on fixya or lmistyrel@aol.com Bye for now.

Very dark screen


Hi yes it looks like the inverter has failed and will need replacing, or if your compitent enough you can fix it at board level. The usual suspecs are a small SMD fuse on the inverter board / power supply board and/or buldging capacitors which look like blue or black cans.

hope this helps.

Bank Monitor problems


Unplug the cable from your PC, if the monitor shows a test image, the monitor is fine and the problem is with your graphic card. If you dont see nothing on-screen after unpluging the cable from the PC, then the monitor in damaged. Send it to repair.
