Question about SAMTRON 78DF 17" CRT Monitor

2 Answers

Yellow Monitor My monitor cable is broken right where it connects to my pc, you can see the shilding inside the cable. I use to be able to move it around just a bit and it would go back to normal. Today i tried to use it and i cant get it to go back to normal, it just stays a tint of yellow. The cable is not a removeable cable. Can i just purchase a new vga connector for it and solder them together? If so, where can i get the vga connector and is there a specific one i need? Thanks!

Re: Yellow Monitor

Simply buy a monitor extenstion cable and cut the end that you dont need and measure the end plug to match the wires on the cut end and simply splice the other cable into place NO BIGGY!! Done it several times. Good luck

Re: Yellow Monitor

Its not something that anyone can do. you'll need to get a new cable and open the monitor to connect it on the inside. to get the vga connector cable you'll need to make the trip to a repair lab anyway, cause its not the generic kind with pins on both sides that you can get in any general computer store. Hope you work it out, and don't get yourself zapped please ;]

Yellow lines on pc screen

A quick check would be the VGA cable connection to the back of the PC and monitor. Make sure they are snug and completely connected.
Some monitors have the VGA cable attached as a separate item and not built into the monitor. If the 15pin plug becomes loose it will show the problems you're describing.
If that doesn't fix it, Next plug the monitor into a known good PC. If the problem still exists, you have a bad monitor...If the monitor works fine on the known good PC, the Video Card/Onboard video interface is bad and will need to be replaced.

LG Flatron W2254TQ My monitor is vertically divided in half with a grayish cast color on the right side, and a bluish cast color on the left side - I can still see everything, but it sure is...

Get a replacement vga lead for it as i am guessing that it has become faulty, try bending the cable where it connects to the pc and monitor and see if you notice a change if it goes back to normal your cable is not attached correctly or it has broken connections inside.

Please leave feedback for me if this helped

-check the monitor cable (vga cable the one with blue connector) for broken pins
-if there are broken pins replace the cable
-if not try another monitor cable or try the monitor to another cable
-if the monitor still turns to yellow after trying another cable or connecting it to another computer to problem could be with the monitor or the vga card

My monitor is change it's colour by it shelf, Why?

This happens to me a lot. It's gennerally the connectors to the computer. Like at the back of the monitor, it might not be plugged in properly or even at the back of the computer. If this doesn't help, it is most likely inside the monitor itself.

I have lost the Red hue in my screen. Any help?

Check the video cable connectors and sockets on your PC and monitor for bent or broken pins. If the cable suffered mechanical stress, a wire inside may got broken or pried lose from the connector internally.
Change the cable for a different one. Connect the Monitor to a different PC or try a different Monitor on your PC to home in on the cause.
If the problem persists and is attributed to the monitor, a fan of the monitor connector soldered to the internal PCB may be lose or broken. This sometimes happens if the connector was pushed in using excess force before.
While a repair shop can fix this easily, I recommend not to try the repair yourself.

Monitor changed to yellow colour.... what is the problem...?

Monitors mix the 3 "primary" colours, in various proportions, to produce all other colours.

Mix equal parts of all 3 colours, and you get WHITE.
Mix equal parts of only 2 colours, and you get YELLOW.

So, either:
1. your computer's video-card is not sending the 3rd colour;
2. your video-cable between the computer and the monitor is broken, and is not transmitting the 3rd colour;
3. your video-cable is not TIGHTLY connected at each end;
4. the electronics inside the monitor that SHOULD be producing the 3rd colour have failed.

Try connecting the monitor to a different computer, with the same video-cable. If it works correctly, your video-card is the problem.

Try connecting the monitor with a different video-cable, to see if replacing the cable fixes the problem.

Try connecting the monitor to a different computer, with a different video-cable. If it still is incorrect, then the monitor needs repair/replacement.

My monitor turns yellow

Computer monitors get separate red, green and blue video signals from the computer, and if you lose the blue the result is a yellow picture. This can be caused by video card failure in the computer (very unlikely), a bad cable (fairly common), or trouble in the monitor (which is most likely what you have).

The usual problem with monitors is bad solder connections to the red, green and blue output devices. These are usually three separate transistors, but sometimes an integrated circuit that puts all three in one package is used. These outputs get pretty hot, and the heat can cause the connections on the circuit board to crack. Resoldering them usually fixes the trouble. (Sometimes the part actually fails, but bad connections are more common.)

The parts are normally in one of two places. Most commonly they are on the small circuit board you'll find right at the neck of the picture tube. Some monitors have them on the main circuit board. They may be mounted to metal heat sinks to help keep them cool. If you can identify them and resolder the connections, you'll probably get your normal picture back.

Check the video cable at both ends to make sure it is connected properly.
Move the cable around near the ends and chances are it will look normal. If so then you have a broken wire inside the video cable. A common thing and easy to get another cable.

F-17 neovo monitor stopped working. power light is flashing yellow

The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.

1 The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or a broken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the monitor will reset just unplugging power cord for one or two hours, sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occurr suddenly are a blown capacitor on power board, the inverter board powering up backlight lamp has blown, or a fault on main lcd controller board.
check also the video cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

Check connectors, try moving the video cable, and if the cable is not built in, then also try a replacement cable.
