Soyo 17'' Monitor (DYLM017A)(VT17N71), identity of fuse.

Soyo 17'' Monitor (DYLM017A)(VT17N71)

Computer was shut down last night, it usually runs 24/7. When turning it back on today the computer booted up just fine but the monitor stayed black. No power lights, no anything. Checked the power adapter with multimeter and it gave the correct voltage (12v, 4a). Plugged it back in hoping it was just a bad connection...nothing. Then tried talking nice to it, waste of time. So I took it apart and started testing for continuity, lost it at the first fuse (F500 label on PCB). Plugged all the wires back in and gave it power. On one side of the fuse I had 12v and on the other side..nothing.

So my guess is that the fuse is blown. I could be wrong, please correct me if you think I am. This is where my real problem starts...I can not identify this fuse. Below are some high res pictures of it and another one just like it on a different board in the same monitor. It looks like a resistor, pale green/blue coat with a single orange band...but to my knowledge resistors have 4-5 bands to identify them. I also have not found a Pico fuse that even comes close to its coloring. There are markings on its case, one side it says ''PSE'' in a horizontal diamond with the letters ''JET'' outside of the diamond. On the other side it has ''SG3A''. I have searched for all markings and the PCB number...nothing.

I did find someone else that described the fuse colors as I have, it was for a ''Mitsubishi TV #WS55511''. I do not know for sure if it is the same fuse or not, just found the description very close to what I am looking for.

The blown fuse prior to removal, shows the PSE JET marking.

Blown fuse removed, showing SG3A.

Duplicate fuse on other board in same monitor (Yes I noticed the crack in coating).

Any help would be greatly appreciated, so far it has stumped me and everyone else that has seen it. The
single band doesn't seem to relate to any color code charts I have been able to find.

    what u need is to check the voltage of power supply circuit.I think the problem is the power ic and the power transistor replace that with new one.Check also the flyback and check also the mylar capacitor value 220 or 180volt 2kv these capacitor is the supplier of the voltage to the crt.check these component.

Orange color of the ring means number 3. Part of marking also contains "3A" so I'm pretty much sure it is 3 Amps rated fuse. But before replacing it measure the resistance on the PCB where that fuse was blown, between common mask (usually metalized mounting holes are connected to it) and the second pad of that fuse. How much is there? If you measure less than 12/3=4 Ohm the new fuse will blow again and you need to find what is shorting the power supply.

I need drivers for my Soyo MONITOR, DYLM017B Model:VT17n71.. Windows 7 is tellin me its out of range


Hi there,

I've spent a bit of time researching this problem for you and have come up with the following, hope it helps.

SOYO has quoted "All SOYO monitors are Plug and Play monitors. They do not require drivers to work". Recently SOYO went bankrupt so their website is now unavailable for any form of support.

What i would recommend to you would be to temporarily connect a CRT monitor (one of those big bulky monitors) to your computer, as these have a larger resolution and refresh rate capability.
Once you can see Windows 7, change the display settings to the minimum settings for your monitor (as a safe bet i'd set them to 800x600, 60Hz until you connect the LCD). Then connect your flat panel monitor again and set the display settings to an optimal level for you.

Again, i very much doubt that you will need a driver for this brand of monitor, and will be hard pressed to find one.

All the best, and i wish you luck :)

Cannot see the full screen


No, your monitor is needing service
The inverter that corrects the picture and the luminous tube ( florescent) that gives light to the LCD is failing. These and some board components are malfunctioning.

When I try to use my 17'' Soyo monitor with Windows 7 program the screen turns black and then ''out of range'' wording is all I get on the monitor. I have tried booting in safe mode, set the resolution to...


When you power up the compute press F8 key then enter in :"Enable vga mode" then go to display property and set screen resolution to 1024*768.
Then check .
If still same then enter in safe mode and uninstall graphic driver then start computer normal mode then install graphic driver.
Also in safe mode go to start->run type in run "chkdsk /r" then press ok then press "y" then restart computer then it fix and recovers error on harddrive.
Let me know if you need further assistance.
Thanks for using FixYa.

Monitor comes on,then goes off after a couple of seconds.Checked the circuit board but found no problem,feel that the screen might be faulty,please help.


Hi,
This could indicate some component overheating/damaged. I haven't worked on a monitor like yours, but on several occassions I noticed that the problem was caused by blown capacitors. This can usually be spotted if you inspect the capacitors on the logic board carefully. If they are bulging or you can see black goo "leaking" from them then they need replacing. Other than that, troubleshooting of other components on the logic board is far too complicated to describe here.
Hope this helps,
Raf

Auto-tune isse


Hi,

you could try adjusting the screen resolution in My Computer/Control Panel/Display this may help.

Also have a look to see if the Adaptor, is set for optimal refresh rate.

MISSING POWER SUPPLY


Normally, the polarity is molded next to the connecter hole; it may not be real easy to see.
If you have a digital multimeter with a 'diode' position, most devices have a diode internally installed to prevent damage in case of a bad substitution and the meter will show a value of somewhere between 500-800, typical would be in the mid-600s.
If you find that, then the meter is currently causing the internal protective diode to conduct as it would if the WRONG polarity would be applied and most meters will supply a positive voltage to the red lead for diode function.
Commonly, the center is the positive contact but this sure isn't certain.

Soyo monitors


your monitor doesnt have drivers for it.. and doesnt need drivers for that matter. It sounds like you dont have the right drivers installed for your graphics card. here is a link to the drivers you need.
